Shadowboard Build from the Basement Shop
ฝัง
- เผยแพร่เมื่อ 17 มิ.ย. 2022
- Shadowboards are extremely useful, but they can be tricky and tedious to build. Often used for aviation tool control in toolboxes, they can actually be very useful around the DIY home shop as well. Here I'm demonstrating a techique that uses a Raspberry Pi computer, Python, CNC router, and some other software (CamBam and Fusion 360) to greatly simplify the process of setting up your tooling inventory with shadow boards. Typically cut from tool control foam, I'm using coextruded High Density Polyethylene (HDPE) from Vycom Plastics for my build (www.vycomplastics.com/)
A short discussion of image components, pixels, cutting tool geometry, and software scripts is also included. I attempted to make this video fun and educational at the same time. - วิทยาศาสตร์และเทคโนโลยี

really love the explanation process! great video
Thanks Christoph!
Just finished watching your PrintNC video. Awesome job, really like both the content and presentation of your videos. (I need to start using audio the way you do) I think you might have convinced me to start designing my next CNC... It's sort of a disease.
Very jealous of your space and equipment. Someday I hope to catch up...
Keep in touch! -Scott
@@scottprints Hi Scott, Thanks for the comment! yeah the CNC is like a disease, once you're infected, your other projects will suffer from a lack of time :D
Hi, Is there any chance I could get a diagram or a step by step "how to" for the software and what else is needed for this set up? I have a raspberry pi and camera, id ike to make one of these. Thanks @@scottprints
@@johnbarrera7998 hi John,
I really don't have more instructions past what I put in the video, sorry.
My god, this video is criminally under-viewed and under-promoted. Amazing job👏👏👏
Thanks! Probably under-promoted because I haven't released much content since this video. I have a ton of ideas, but time... Not so much.
Great job! Looking forward to the socket/ wrench storage board!
Guess I'd better start designing that!
Ahhh the bench, ingenious way to have something be multifunctional. Great video!
Thanks Chuck, glad you remember the old office benches.
love it, please make another video. I'm invested
More to come!
Great video, you've just gained another subscriber. Please make another one as it was genuinely interesting.
Thanks Benjamin, I appreciate the encouragement!
Hey there. I've never actually commented on a TH-cam video before, but I thought your presentation and your helpfulness really stood out and deserved some feedback.
I love that you're using open source software to do this, but also that you've made it accessible. Your speed of presentation was brilliant and I particularly enjoyed your tangent on cutting heads.
Definitely keep producing videos and tutorials and good job on making it to Hackaday. :)
Hey, thanks! I feel honored to be the recipient of your first TH-cam comment!
Quality video and nice work! Watched it from beginning to end (which definitely doesn't happen with most videos). Thanks!
Thanks for watching and for the comment!!
Loved it. This is how a video should be done.
Loved the video! The explanation and walkthrough of your process was super interesting and I'd love to see more of what you are working on. Keep up the great work!
Thanks! I appreciate the feedback!
Killer mix of skills! Very impressive
Thx!
I loved this video. Everything hit home for me from the imaging to the final board. I'm going to look for more on this including the imaging setup you have. Thank you!
"Stuff Made Here" (I think his name is Shane) just did a video on a robot that measures puzzle pieces. It also uses a camera and a backlit light. Shane's significantly better at this stuff than I am, so his video might give you some ideas as well.
I absolutely love the video, perfect balance between tech and fun ! I'm a fan !
Thanks!
As a fellow aviation background with a messy toolbox this touches my soul.
Yep.... Not like working on cars!
100%
I'm gonna be honest, this made me more excited than it should have.....
So freaking cool
Simply the most awesome way I’ve ever seen to build shadow boards!!!!
Thank you, I used to be a tooling manager at several aircraft manufacturing facilities. I got really frustrated with typical shadowboard design & fabrication processes so I came up with what you saw me demonstrate in the video.
Awesome video Scott! Please do keep the videos coming. I'd be very interested in a video about your imaging processing workflow on the Raspberry Pi.
Thanks!
It's though to decide what to do with that workflow. On one hand, people seem interested. On the other, I'm absolutely a novice programmer and I don't want to present bad practices (and I know that I my code could be vastly improved)
@@scottprints Very cool video! I'm also very interested in the build of the image processor.
I would love to see that as well.
@@scottprintsHow about someone that works in Python every day? I'm getting close but I'm missing something. I could help clean up the script you're using. :)
@@StellarEclipseStudio I think I'll take you up on that! How do I contact you outside of TH-cam?
The shadowbox device is something I need to look into. I think it would be a great addition to my shop. Thanks for the video.
it definitely peaked my interest! I went through the whole "cell phone, inkscape" process, and I gotta say - I'd much rather build the shadowbox and use that process. Genius!
Loved you video, great work on the shadow boards. Well done and thank you for sharing Dave
Thanks, it was a fun video to make.
Excellent Video, Thank you!
Strong work. I found your video very informative and well explained. Your flow was easy to follow and you stayed focused on the important steps of the process.
Thx!
The skills and craftsmanship are truly exceptional. 👌👏👍
Why thank you!
Really great video and explanation. Inspiring
Really awesome video Scott. Excellent end result. I do like the subtle plugs for each software used and its application...gives a really good lead-in to the more in-depth concepts to explore without getting off-topic.
Thanks for noticing that. This is one of those projects that builds on lots of other skills, and it would have been really easy to go off on tangents in any number of places while documenting this process.
Appreciate the comment!
Great video. Just did foam this week for a small pliers drawer. Really like the tool capture camera.
Thx! It's a work in progress. Got a few ideas for improvements, but I have no idea when I'll have enough time to play with it again.
I would love to do this to my toolbox! Looks super clean.
Thanks Josh,
I'm planning on doing a video about a less technical version of this technique. I think that learning Python, CAD/CAM, and access to a CNC is a fairly formidable barrier for most people that watch this video. But there are some other methods that can create the same effect.
Hope to be able to work on that video soon. Thanks for the comment!
That's great! I don't have a cnc but I can use much or the process for 3d printing custom boxes etc. Thank you for sharing.
Thank you. Love the concept of the video, but the complexity made me save it so I could go back and develop a process to do the same thing (parse it out to get the overall job of organizing tools to save time as a system). Thanks again for the great video.
You're welcome. Glad it was helpful.
I was looking for materials and a good video. This is absolutely gold! It came up quite randomly in algorithm. Your employer has it right. I would never have heard of them if it was not for you loading this tutorial. Thank you! Keep it coming
I should charge Vycom for my marketing!!
Thanks for the feedback!
I don't have any training like you do but i understand your explanation of the cube color and as you move around the cube the color change awesome
Thanks for the comment! Truthfully, I don't have any training in this area either. I watched a lot of TH-cam videos and played with Python a bit. I never went to school for any sort of CNC or programming education.
I'd DEFINITELY like to see a follow-up video! I'm not in aviation but since I'm working on restoring an antique car stuff like this really helps designing neat and organized tools (mostly since my dad can't do the same - drives me nuts). Definitely worth the subscription
Welll, feedback seems to be fairly positive. Guess that's my signal to start working on Part 2.
Thanks!
Scott, like always outstanding instructions!! I think I will bring my tools to you to have them shadowed. I I think this would work to make something nicer for the every day kitchen for storing our silverware, spatulas, larger spoons, tongs…. Ideas are endless. Amazing video! Keep them coming.
Thanks Pat! Great to hear from you again!!
Well done! Great explanation and your boards are really accurate!
Thank you, it's always fun to see the boards that you put up on LinkedIn as well!
Great information. I'd love to have the ability to do this. Well done.
I'm thinking that I'll do another video on a different method. One that doesn't require Python scripts or a CNC. Standby for that!
I definitely need to shadow/french-fit my tools, as all of us do. I probably won't build the shadowbox measuring device you have, but the general "photo-to-toolpath" workflow absolutely seems like the way to go.
Good luck! Post some pics if you complete the effort and share the link!
Thanks for the video: this is a wonderful idea and video, which a good explanation of both the theory and how you made the "scanner".
It was a lot of fun to make!
Actually, I'll be working on it more today. I upgraded to a raspberry pi 5; looking forward to seeing how that changes the performance. Plus I want to make some code changes.
Great video thank you for sharing your process.
Thanks for watching! I appreciate your input, Josh!
I'd love to see how you built the shadow box camera
It's all Raspberry Pi hardware. You can find separate tutorials for hooking a pi to a touch screen, input buttons (switches), camera, etc. The scanner is just following all those separate instructions while making the wires long enough to fit into a box. That's pretty much it.
Wow! Love the awesome video ... went way over my head. Ethan from down under.
Thanks!!
Awesome work!
Thx!
Nice work, really pro scale finished product👍
Thx!
Great video. Thanks for sharing!
You're quite welcome, thanks for the feedback!
Thank you for sharing your techniques. I’m looking at doing something similar with my toolboxes and various projects I’m building. I don’t have a CNC router, but I do have a couple of laser cutters. I will be cutting layers of EVA foam to achieve similar results. Going to research the camera method you used. Way faster than measuring with digital calipers and creating a CAD model.
Good luck! Don't forget to post back here and let me know how your version of this project worked out!
Fantastic, the DIY picture capture and editing blew me away, this is extremely handy. A video on how to make the capture system possible would be great.
Very Cool never thought of using my cell phone to get the shapes.
Yeah, you're going to need to include something in the photo to establish scale (say, a coin or something else of known size). But it can be done with a cell phone camera.
Great vid, hope you make more
Thanks! I plan to as time allows.
Great video with a good explination. I like to use a flatbed scanner and corel draw for doing something very similiar. The poly material you used is indeed neat stuff, heavy as heck but neat and tools literally last forever when cutting it. An endmill will last tens of thousands of inches in this stuff. Thanks for sharing.
Thanks for the comment!
Yep, we cut this stuff at work, and it isn't terribly hard on the tooling.
Hey.... I've been wanting to ask about doing this on a flatbed scanner. How does the profile capture work with tool edges that are a couple inches away from the glass? I wanted to re-create this contraption with a scanner, but I'm worried that thick tools will be out of focus if parts of them aren't right on the glass.
@@scottprints I dont think I can say that I have done anything 2" thick. If it had straight sides I think it would not be a problem since as you know th scanner bar is always looking straight up iff you will as it moves along the bed. I have done lots of cardboard patterns for things that I want to profile and cut in more expensive materials like carbon fiber and such where you really want to get it right the first time. It has always worked perfectly. Lately I have been tracing around wrenches, pliers and the like for foam inserts. That is what brought me to your video. What my method lacks in refinement however is the fact that I have to bring a PDF of each tool into autocad and then manually trace around the object that i want to shadow with a polyline drawn manually. It is a tedious process and it can take a few hours to trace around a whole tray of wrenches. Sometimes I profile cut reliefs when I want it to go all the way thru the 13mm EVA foam, and other times I cut relief pockets in the foam by laser engraving partially thru the foam for shallower stuff. I then stack up 1 to 4 layers of the foam with the corresponding cutouts and glue them all together. Again it is not a a fast process, but it sure does look amazing when it is done. I use 24" square EVA foam gym floor tiles from home depot or Amazon as it cuts quickly and beautifully with no residual stink on the CO2 laser. Again thanks for the inspiration!
Wow that and awesome setup that photo setup is so mint!
Thx!
Pretty good video. I appreciate the dry sense of humour underlying. It was fun. It was educational. and, even better, it was timely. You have earned a like and a subscriber. Hopefully, you will have more videos in the future.
Thanks Riggsron, I appreciate the feedback. I really enjoyed making that video, I have another topic in mind fory next one. Just need to find the time to actually make it.
oh man this is an awesome video ! you'd make a great teacher !!
I've been told that before! Thanks!
Awesome project! I wanted to share a way to keep the tools in the slots. I have kids that use my tools, but I need the tools back where they belong. What I did was spraypainting all the tools that same color as where they are from, in your case it would be the same color as the shadowboard. That way, it makes it easier for them to know where the tool belongs.
Another hack I do for my metric sockets is spray paint paint them in sets of five as a sequence of red, orange, yellow, green & blue. Every red is a multiple of 5. For example, one "rainbow" set would be red 5mm,orange 6mm, yellow 7mm,green 8mm, blue 9mm. Another would be 15,16,17,18,19mm. That way you can quickly know going up or down which increment of metric you need without squinting to see the number.
Cool hack, thx for sharing!
Fantastic production. Start to finish. Highly entertaining. Can we just send you our tools?! 🤣
Ha! I haven't even finished my own toolbox yet!
Well that was awesome. By all means, keep filming!
Thanks!
Exact TH-cam channel I needed
Good to hear! What sort of projects are you working on?
@@scottprints I'm currently in tech school during my highschool school day. Me and my other fellow classmates are working on a shelf with 6 casters on it 4 of them being locking and the shelf's have rubber on them. We are building it for Aurora flight sciences. They have cool cnc machines, fixtures, robot machine tending, paint booths it was really cool to tour there facility they even have a computer inventory system that is like a vending machine but for tools and PPE... We finished the shelf but still have to mount the shelves on the beams which at are a 45 degree angle. There will be 4 shelves on it to hold airplane rotors that Aurora flight sciences manufactures. I'm still learning manual and cnc machines at my school and I find it very interesting. I like making things and I learn something everyday in this industry I love it.
You are awesome! I totally understand wanting to make videos but not having enough time. I just added "attempt to make a photo box" to my video list. I've never written any Python code before, but with all your helpful answers to the comments, I think I might be able to figure it out. If I do, I'll make a video and link it to this one.
Good luck, and thx for the kind words! Concerning Python: your local public library will probably have some good "getting started with Python" books. That got me started and I was able to hobble through enough code to make the shadow board box from there. Please keep me posted!
SVG bench is really cool!
Thanks! It was fun to build.
A video on how to make the camera system would be awesome. I have a pi and the camera. Would be great to make that ! I have been asked to do this with my laser and I would love to build a little bench like that.
I wish I had the time! Would love to make a video like that, but I have had 10 minutes to call my own in months.
Thanks for the suggestion though!
@@scottprintsthere are definitely people who would value that information and would enjoy watching! I subscribed in hopes I see that video pop up on your channel soon.
@@tomaschacon4275 Hi Tom! I'd love to make a detailed video about the camera system, I really would! Unfortunately, I just don't see a lot of free time in my schedule anytime soon. Thanks for the note; if a few dozen hours worth of free time ever falls into my lap, I'll make a camera system video for you.
Take care!
@@scottprints No worries, I understand how busy life gets! If you get a free chance, you should post a few pictures of the internals especially wiring and post them on your community page. I get a full video may not be in the cards but some photo references would mean a lot. Thanks again, awesome video!
Slick set up. I need to figure out a way to do this.
Awesome Video, thanks for sharing! Any possibility to share more information to build a „photobox“ like yours?
Please do a more in-depth video on the lightbox-bench. I'm thinking I need one of those!! Thanks!
Agreed! That would be awesome for all kinds of stuff!!
Came here to say the same thing, I need one of those light boxes In my life
many thx for the hints
Awesome. Thanks.
You're welcome!
Hot damn. Those are beautiful shadow boards.
Very cool scanning device, too.
No space for a CNC mill at my current shop - but I sure hope I can get one someday :-)
Good use of that Pro-Lift mat too - I tried using it to shadow with a box knife and it sucked but the mill would obviously get it done :-)
I'm impressed that you recognized the Pro-Lift mat! I've cut up a few of them. Too bad they're so small, I wish they came in bigger sizes.
@@scottprints haha yeah -- I've been down this road a few times! I actually ended up stacking gardening knee pad/mats from the dollar tree for my shadow boards -- as it cuts perfectly with a razor.
The pro-lift it's very economical for what it is -- but it is so difficult to get a clean cut -- --- I even chucked a nice endmill in my hand drill and it cut fine -- but it was tedious and hard to get it to look right :)
It's actually pretty nice for rolling around on the ground tho :)
It's a shame they don't make them wider -- finding bulk foam like that is $$$ -- just goes to show economics of scale matter!!
@@IroncloudMetalworks I have a theory on why bulk foam is hard to obtain. I could be wrong, but I think that shipping costs destroy the economics of good shadow board foam. It can't be terribly expensive to produce; but the shipping costs are probably why it's so hard to find.
Yes please for the sockets!!
Very nice
Excellent video. Well produced, and amazing content. I dream of having such a workshop. Maybe someday. My only complaints are regarding the lack of Little Ponies and Sharks in your toolbox. LOL
Somebody finally noticed the humor!! Congratulations Bob, you're the first!
And shops are fun; highly recommend that every person should build their own 'me' space someday. They're great!
great video! would love to see tutorial for the picture box build.
Thanks!
Dude, I am begging you to do an in-depth tutorial on building the silhouette box. I would happily buy the plans for it, or donate to your channel to get this video.
I wish I could! But I have no time right now. That CNC you saw me operating in the last video is in about 200 pieces now. I need to find a new workshop and get my equipment set up again, and that all has to happen in the scraps of time that aren't taken by other priorities. I'd love to make more videos, but I just don't see any room in my schedule for the effort. Thanks for your interest though, it's always nice to get positive feedback about my builds.
Awesome video. I'm a maintenance manager and trying to optimize the effectiveness of my team and I 200% agree that a razor knife and foam is a half-effort into a good direction. I am curious though (because foam is less expensive than the materials you used), how you mapped the outlines with your shadow box (and how I could do it) and use that data to laser cut 5S foam inserts instead of CNC. Thanks for taking the time to make this video. You explain things very well for people to understand.
Hello Mike,
If I were you, I'd back into the process from the end. So start with your laser and cut a piece of foam with it. Can you make a shadow board? If the answer is "yes, but it takes forever" then you're ready to start improving the other parts of your process. That's how I did it, I started cutting foam with a scroll saw and constantly looked for ways to take the pain out of the overall process.
If you have a CNC of some sort that can cut a shadow board, then start looking for ways to automate. A next logical step might be to map out your tools in some CAD software (semi manually), then after your team is comfortable with that process, build a rig like the one I demonstrated so that the silhouette generation process gets easier.
Hope that helps, let me know if you have more questions.
Yes please!
Hey Scott, this is an awesome project I hope you do cover this in more detail in the future. I'm going to attempt to build one of these myself as I have great application for it for internal company use. I do have a question, you mentioned what you have the red and blue buttons do but what are the others for?
Ending scripts, starting scripts, and looking cool. They came in a 5 pack, so I decided to wore them all in.
you’re so good at explaining this stuff, what did you study if you don’t mind me asking? Cool stuff man
My masters is in 3D printing
Great Video! I did some Shadow boards in the Past as well but digitalising the tools was always been a pain. Could you share more details on the Box you use or might share the Python code? Cheers
Do you have a instructions on how to build the shadow box? I think this is such a great project. Thanks!!!
Hi.
Sorry, all that I have documented is what I presented in the video. A few other people have asked for more info, but I'm not sure how to pull it together. Just the video you saw was a lot of work; I'm not sure I could cover everything in depth without neglect other parts of my life.
OK - first, great video. Tons of very unique and useful content. The project was very well executed and the choice of material is super interesting! Have you ever used your CNC to cut out the Kaizen Foam material? Does it work or does it tear it all up? I really did enjoy this video though and this is the first time seeing one of your videos and I am subscribing. Cheers.
Thanks! I have used my CNC router to cut foam before. It works, but dense foams work much better than soft foams. I think Kaizen foam would be OK to cut, but might be pushing the limit on "too soft to cut with a router". Dunno... only way to know for sure is to give it a shot.
Appreciate the subscribe! Hope I get some time to make another video someday. Life's been pretty busy lately.
@@scottprints "Have you been busy?" that is a joke from a band named 12 foot Ninja on a song called One Hand Killing and they do a bit of comedy at the intro of the video... pretty funny but if you don't know them it may not be... Good song also if you like modern progressive rock music.
I also have been busy, got a new job a year ago and turns out this squad works massive amounts of overtime and Saturdays and right through some of the holidays!!! It sucked but I learned a lot and got a different position where we only work a bunch of OT! But better than not having a job. But I did literally noting other than work for the entire year so it was rough.
Anyway thanks and I'm looking forward to seeing more of your videos. Cheers
Annnd you just earned a subscriber! I have been wanting to make shadowboards for my toolbox for a long time now and have been discouraged by products like Kaizen foam (mainly due to the astronomical price of it) I am in the final stages of building my CNC router and this would be a perfect project for it!
Do you have your scripts for your machine vision camera setup posted anywhere like Github?
Can't wait to see more projects, now I need to go find that pesky 10mm socket.....
Good luck, keep me posted on your progress.
No, I don't have my scripts posted. Mostly because I'm a novice programmer and this was a learning experience for me. Consequently, my script is poorly commented. While it works, it could be MUCH better and I know that I'll have to re-do it soon.
Cost of the material is always a challenge. As I said in the video, I'm lucky enough to work in the factory that makes Playboard. I was allowed to take home some scrap for this project. If I didn't have that resource, I'm not sure I would have been able to make the video.
Thanks for your comment!
@scottprints , that's an amazing video! Your scanning device is a brilliant idea! I was wondering what are the dimensions of the back light surface (what's to biggest tool you can fit in)? Speaking of dimensions, how do you define the distance between the camera and the tool? What's this distance value in your case?
The shadow box is awesome! I’m interested in either building one or purchasing one, any information you can provide regarding either?
If I were you, I'd start by working through the software as 1's and 0's are free. Get started with your language and hardware of choice (I used Python and Raspberry Pi products) and build out a working model on the bench. If you can get that to work, then go bigger and get a box to put it all together with a backlit stage. Good luck!!
Awesome video, any chance you would share the script you wrote? I would love to build a tracer box, but only starting to learn OpenCV.
Thanks for the feedback; but I'd rather not share my code anymore.
The photo-bench is adorable. (I'm afraid I'd never be able to keep it from getting buried underneath things when I wanted to use it, though...)
Do you find the intensity mapping accurate enough (you mentioned doing a bit of shape cleanup but it seemed to mostly be about being smart about the tool, rather than fixing glitches?) Or would a black lining (so there was less reflected light on the camera-facing surface) help, maybe for chrome tools (like the socket sets that you're doing next)?
Well, the trick is in how the cube is broken up. I find that I get better results if the split is closer to the white corner of the cube. That way, the pi has a better chance of labeling shiny tools as "tool pixels" -otherwise shiny pixels can get mistaken for background pixels.
But yes, the black lining is a good idea. I've been toying with the idea of painting the inside of the box black.
This is amazing. Do you have a details on the bench / photo booth ? I hate to say this right off the bat but I would buy one of those readymade happily
Thanks for the feedback! I really don't have any additional info past what I put in the video. If you have a specific question, might be able to point you in the right direction. But I don't have a detailed "how-to" guide for this project.
Really love the photobooth, and the video!
Liked for showing the exact Chess Set my father taught me chess on!
Classic Games, circa 1960! Great chess set!
8:25 cool to hear from an employer. Thanks for sharing!
Yeah, I enjoyed working for Vycom. I left almost a year ago, went back into aerospace. Though I do very much miss access to scrap HDPE...
Hey great video, awesome process! How do u make sure the scale of the vector outlines is the same as those of the tools in real life? Thanks appreciate it!
Hi Sam,
Scale on a tool of known size and remove the barrel distortion will get you most of the way there. Parallax error is still an issue, but keeping the camera as far from the tool as possible minimizes that error.
@@scottprintshow to counter the barrel distortion using a phone? Taking overhead pictures using a white background with lights to minimize shadows? Thanks for the video, info and your time
@@CisnerosShop well, I think "how" you take the photo (in your case, with a phone) is irrelevant. What's important is knowing how much barrel distortion is inside of your images and then removing it. You may want to do a search for "openCV barrel distortion correction" for some examples that show Open CV being used with Python for this function. Then you can take that knowledge and apply it to your project.
Very impressive. I made a shadow board by tracing the tools onto paper then photographing the paper as a hack to avoid the camera distortion, then tracing the image in CAD and carving on the CNC. Any chance you'd make the Raspberry Pi scripts public? I'd be very tempted to also build an automated scanning box.
At the moment, those scripts are so cobbled-together that I think they'd be more trouble than they're worth. Maybe someday if I re-write them, I'll put them up on GitHub or something.
@@scottprints Even documenting the steps a bit more would be valuable. I can write my own Python, just could use a head start on the process.
@@StevePrior I agree. It's better to have a jumbled toolbag of code to start out with and then polish than to have nothing to start with.
would you be willing to share your cut out file? I do not have the necessary training to build the lightbox
Great video +1 Subscriber! I've been wanting to build shadow boards for a long time, but have kept being put off by the bad results of taking a photo and trying to clean it up to an acceptable standard before actually building the board in CAD. I've tried so many methods, but always end up disappointed. Your RasPi solution is just genius. Please could you share more about it's components and the scripts that tie it all together?
Do you have a more specific question? I did everything that I could (short of posting my script) to convey the process in my video.
@@scottprints Short of posting the script, it would be most useful to me to understand the libraries you used to automate the workflow of photo to usb stick at the push of a button, so I could have a go a coding something similar. I've taken PiCamera and PyPotrace from the video, but have little understanding how you isolated the tool from the background. Although I get the theory, not sure how you produced that in code.
@@__stuart__ sure! Use PiCamera (or PiCamera2 nowadays) to make a 3 dimensional array in NumPy. Then you can use some match functions on each pixel to determine its distance from either the black or white corner. Once you have that distance, each point in the array can be categorized as either "tool" or "background"
That ought to get you started! Good luck!
@@scottprints Just wanted to loop back and close this off. I've got some code that I'm happy with for now (these things are never "finished", right?) to extract the tool from the background using PiCamera2 and OpenCV, now just need to find some time to have a play with Fusion360 and the CNC. Thanks for the pointers - really useful starting point.
@@__stuart__ Code is never finished. Good luck, and keep me posted!
hello.
i appreciate this video and now I want to build a fotobox myself.
Are the programming steps in python the following:
- taking the picture converting to bmp
- then using undistortion library opencv
- convert bmp to svg or eps with portrace library
- sending to a folder on the network or usb stick?
thanks for your advice
best regards
Hello,
Yes, that's pretty much the Python workflow. I prefer to have Potrace output .dxf files, but the .svg or .eps formats you mentioned would work just as well.
@@scottprints 1 question.. do you have all the pictures on 1.dxf or are those multible
@@hrykne6134 I have the script spot it out both ways, generating each .dxf individually and one master .dxf. that way I can use whatever output I need and send the rest to the recycle bin. Gives me more flexibility.
are they useful tuts for the opencv part, I want to first rotate ä distortion operation but just finding those chess board tuts with cam adjusting...
god stuff.... how much wass your cnc machine?
I built it for about $3000 in materials.
Hey so In this video at 1:15 seconds, you talk about the bench processing your image into a geometry File. Would that be a SVG file? Please forgive my ignorance this is way above my pay grade but I need this thing in my life so I’ll take the time to try and learn how you did it.
Could be an SVG if you want. But I use a DXF. Both would be suitable for this sort of application.
Another question, about the voltage converters. You have two, what are they used for?
@@ammonsequiptment9877 pi runs off of 5 volts, the other changes the voltage going to the LED's, which is how I change their brightness.
I'm gonna show this to my boss to try to convince him to let me make our shadow boards in house
It's the way to go! Do me a favor: post back here after you've had the conversation with your boss. I'm curious to know how it turns out.
Are you in aviation?
@@scottprints will do! No I'm in industrial automation. Ever heard of Festo?
@@jpwd1999 no, but I'll head to Google right now. I'm all about industrial automation. Stated differently, I don't know anything about industrial automation, but I think some Python and a few sensors placed strategically around my factory might be super useful.
Great Channel! Just got subscribed :) give it some time and you got 1mln subs 😃
Thanks!
Hi
I tried to also build a python code and its working so far.
It keeps me wonder what image size you are using for the jpegs. If my code iterates through every image by pixel to decide by given threshold what is white 0 or not, it takes quite a time for example 10 images including all steps to get one dxf file with all tools in it. I have had several methods also without the iteration loop.
I also worked out a scaling solution and this takes me to the next question. Did you messure and scsle the tools in the CAD software?
I am using a raspi4 with cam module 3 and the picamera2 lib.
Would be great if you could give me a hint. 🤓
Hmm... I think that looping over every pixel in your image is causing your slow code. Try setting up your image in an array (say, with numpy) and do operations on the array instead of individual pixels. Hope that helps. I'm not a terribly accomplished programmer myself.
this I could try... especially since picamera2 (libcamera) does provide an output in an array 🎉... and did you automate the scaling? I also did object recignition with a ref and scale it by converting with potrace but this also gets sticky😅
@@hrykne6134 all my scaling variables are fixed as my setup has no distance variables. So I don't need auto-scaling.
so, I nearly finished..😅
did you do any optimizing on the BMP files?
what threshold number to decide wheter pixel go white or black in the BMP file?
I am asking because I not already happy with the lines of the tool in the bmp file.. they not that smooth...
@@hrykne6134 depends on the intensity of the backlight. I made it a variable and change it if it seems to be giving me bad outlines. You're going to have to set up strategies: shiny tools will need a different set of variables than flay ones, etc.
You end up needing substantially more surface area with these things as you aren’t maximizing any vertical space.
Personally don’t mind a wayward wrench placement on top of a screwdriver.
I’d probably need a full on warehouse and an even heavier OCD diagnosis if I were to “shadowbox” all of my tools.
In dense toolboxes, it can make sense to stand tools on their sides. That usually means putting them into deeper foam or getting support gizmos to hold them in place. There's also a lot of influence from the sort of environment the tools are in. I've had a few guys with automotive backgrounds mock my "overkill" because this just isn't needed in an automotive environment. But guys that come from aviation tell me that I haven't gone far enough.
Holy Cr@p Man! Maybe you can call Dustin Hoffman to help you with your OCD!!! My man man Vern!!! LOL. Great stuff.
Who's Dustin Hoffman?
Anyhow, thx for the kind words! I made that video more than a year ago and I'll bet that those two drawer inserts have saved me hours of "where did I put that (insert tool)".
Probably hasn't been a compete wash yet, but the drawer inserts are still really helpful.
I have shadowed several tool boxes using just an ordinary router and using tumbling / yoga mat material as the shadow board. I want to step up my game using your method. However, it maybe a little over my head. I have watched this video no less than 8 times already. I have been researching these Raspberry Pi computers. I am grasping it a little bit at a time I will figure it all out. How long that may be I don't know. To make a long story longer, if I paid you a consulting fee. Maybe around $50 an hour, or whatever you and I deem reasonable, Would you allow me to consult you?
I'm not sure that I'm enough of an expert to accept cash for my guidance, but I'll help where I can. TH-cam doesn't have a messenger feature, but look me up on LinkedIn (I work for The AZEK Company) and I'll see if I can get you pointed in the right direction.
@@scottprints ok I never really used LinkedIn, or any other social media for that matter, TH-cam excluded. However, I am interested enough about these subject matters in your video to step out my comfort zone. My first step is to buy a Raspberry Pi computer and camera and work with that enough to at least know what to ask. Thank you Sir
@@josephcarlat9414 let's start with programming a little bit of Python. As a good friend of mine said: 1's and 0's are free. So get a feel for the software for zero investment, then branch out and buy a piece of hardware (raspberry pi, etc.)
@@josephcarlat9414 You may be ahead of where I think you are; but can you program in Python? If not, there's a really nice getting started app from CODELIBR that you can download to your phone. I found that very valuable as I was getting started.
Sockets and wrenches.
Yup. Need to design that drawer next.
ICT?
How can I contact you？
How do I get in touch with you?
LinkedIn might be the best way.
