As I recall, the audio is only on one channel, left or right. I suspect that you are "listening" to the audio channel that does not have sounds. Sorry about that. Chris

Good morning! Good question. Think of the device as having individual resistors as you stated. Each one can be ON or OFF or ALL ON. The resistor value is dependent on the total current of the circuit. Using one resistor for 7 LEDs would be a different value that one resistor for 1 LED. Hope that helps! Cheers and Happy New Year! Chris

Good morning. There are some documents that are available on our companion website. This link will take you to the page for all the Woodworking related documentation, look for W083 molding plane makingstuffwithchrisdehut.com/woodworking-files Cheers Chris

Good morning sfo1mas, I am glad you found that video helpful and useful! May your surfaces be flat and smooth forever. Cheers! Chris

Good morning TheMadface80, I am really happy to hear that you found a solution to your problem! By chance, is that why your 'name' is TheMadface80? Hopefully you will have a happy face now that you are moving forward with your project. Cheers and Happy New Year! Chris

Good morning Martin, I would be great if we could see what the Tiny Code Reader sees, but we can't. All of my experiments with lighting had to be done blind and analyzing results based on suspicions. Once I discovered that the overhead lights were the problem, (which I can set their brightness and their angles which didn't help), I moved on to the LED. In my testing, I did try angling both the LED and the Camera in an attempt to achieve better performance. I didn't notice any improvement by doing that. Just having the LED helped with reliability in all locations on the layout. Hopefully the Tiny Code Reader stays working reliable as it is right now as I just discovered another major problem. I knew this project would be loaded with challenges, but WOW, NOT THIS MANY! Cheers! Chris

Good morning Ron, That would be awesome. Frankly ZoomTown's marking and signs are getting pretty overwhelming!. Cheers! Chris

Good morning Steve, The thought never crossed my mind. I think I probably got fixated on that join function and got lost in that. Great suggestion though! Cheers! Chris

Good morning ariketola1602, Thanks for the feedback, much appreciated! Cheers! Chris

Hello ronaldchinn5967, glad to hear that you found this video, hopefully you also found the one related to interrupts! I have been trying to keep good notes, but like you, there wasn't a "good" tool for me. The tabs certainly are the key for me. I can organize all the different information and find it FAST. Before, I would have docs made with Thonny, Google Docs, Notepad, you name it. Never could find anything and it drove me crazy. Hopefully you can get into the routine because, as I am finding out, it is a massive time and frustration saver. Us old farts have to help each other out (I'm 63 and need all the help I can get). Cheers! Chris

Good morning wktodd, Thanks for the feedback, I really appreciate it. My hearing is so bad that I am usually just hoping people can understand what I am saying. About the only Audio correction I do is when there is white noise in the background, especially when the furnace / air conditioning is running. I can't say if I hear the "noise" of 'S's, but it may be in one of my dead frequencies that I can't here. I just looked at Audacity to see if it had a de-esser and didn't see one. Perhaps someone has a plug-in for it. Thanks again, much appreciated! Cheers Chris

Good morning sashidharprabhu5067, I am really happy to hear you enjoyed that video. David was great at explaining a lot of different aspect of woodcarving. His contributions to the community will be remembered. Cheers! Chris

Good morning StudentTrader, nice to see you again. You description is correct - sort of. Power the servo motors as you described with an external source. Connect your PWM signal to the servo as you suggested. BUT, you will need to connect the zero volt (negatives) from the Pico to the zero volt (negative) of the bread board as well. This will keep the reference voltage (potential) the same for both individual circuits. Adafruit also has a board that allows you to control multiple servos that I have used and it worked good as well. Cheers! Chris

@ okay great thank you! I just tried to get the 16 bit servo driver to work with the pico but no luck but I’ll keep messing around with it

Good morning dylanjennings3746 Glad it helped! Cheers! Chris

Good morning Fant01, I am glad to hear that you found the explanations to be helpful. Cheers! Chris

Good morning wktodd, Thanks much for the encouragement! In the real world I am about 5 weeks ahead of that video and a lot has changed - A LOT!!! Committing to a big change (complete rewrite) is difficult at this phase of the experiment, however, things are "MUCH MORE GOODER". The results of that commitment will be the topics for the next 4 or 5 videos and overall things are so much better. Some really cool additions and changes are ahead and they are providing good results. Thanks again and Cheers! Chris

Good morning SteveWoodgate, Good to see your comment. Yeah, your name has been mentioned many times in recent weeks in the shop - I think you are going to be really pleased to see what is being done with that sensor! Cheers and thank you so much for the suggestion and for the financial contribution, it made a WORLD OF DIFFERENCE on this project. Cheers! Chris

Good morning Starlight-AG, Thanks much for the kind words and perspective. As programmers and tinkerers I believe everyone goes through this experience but few are comfortable talking about it as it can be perceived as failure. While certainly exhausting to think about a rewrite, it is filled with new opportunities to learn, improve and innovate. In the next handful of episodes, things will certainly be changing ;-) Thanks very much for sharing your thoughts and beliefs. Cheers! Chris

Good morning sbelyo, It depends on what is being powered with the single power supply. I am assuming you are powering the PICO and the Coil of the relay. Assuming the coil side of the relay has the proper components for circuit protection (flyback diode) and the coil is 5 volt and the PICO is powered with 5 volts, then you can. Cheers Chris

@@MakingStuffwithChrisDeHut perfect!

Good morning vetrivendanshanmugasundara2507 I am glad you found it useful, thanks for watching! Cheers! Chris

Check the specs for the I/O ratings and it will help you understand why buffer chips exist. Another factor is the package still readily available for through hole applications which means they can be easily used in self made "circuit boards". Being the "cheapest" isn't always the right choice. Cheers Chris

Good morning jimw1266, Thanks for the very kind words of appreciation! That is great motivational fuel to keep me going. Cheers! Chris

Good morning jimw1266, LOL! For a minute there I thought someone was reminding me of which pills I take in the morning! Thanks for the chuckle. Cheers! Chris

Good morning chadmetzger5353 , Unfortunately, I have nothing that could help regarding an SPI LCD display. Sorry, Chris

Good morning Starlight-AG, Thanks for sharing your perspective. I think all of this is why we love programming so much. There is simply never the "best possible" way. We can find alternative methods and never stop. All that exploring and thinking and learning costs little (financially). It occupies our time and mind excessively :-) Cheers! Chris

Good morning alentanor, Thanks for sharing your wisdom. Cheers! Chris

or the one with the most spare time ;)

I guess that depends, Raul is 467 Lbs, how big are you? Cheers mate. Chris

It isn't always about the cost. I certainly can buy cheap drill presses and I get what I pay for - usually junk. When possible, I prefer to make the tool the way I want for the purpose they are to serve. This drill press serves me much better than any of the commercial ones I have owned. Not everyone cares about that, but then again, not everyone drills .008" diameter holes in copper plated G10.

@@MakingStuffwithChrisDeHut agree. but you said in the video "i used some scrap aluminum..." like dude..that's not scrap..that's expensive as hell. only one piece of aluminum costs 50$ ....

@@MakingStuffwithChrisDeHut you are not even showing how precise it is. and the rails have a awful noise - are they Chinese? just nonsense...

@@bambumbambu Thanks for your feedback. The rails are surplus from Ebay, but they run straight which is all they need to do. As for showing it's precision, I frequently drill .010" (0.25 mm) diameter holes with it using carbide drill bits. Out of curiosity, why do you keep coming back to throw shade on the project?

peterwest1158, Wow, sounds like an awesome project, enjoy the process! Cheers Chris

Good morning Tomek, always great to hear from you. I think that would be another great experiment and demonstration of the power within these algorithms. It will be very interesting once this whole thing is up and running and we can try out all these changes and watch the behaviors in the "real" world. You pizza sounds MUCH BETTER than mine!!! I think the thing is called a "Baking Plate". I am going to suggest to my wife we get one so that we get more consistent crusts and hopefully less spilled cheese on the burner which causes the fire alarms to go off! Come Friday night I am too exhausted to jump up and start opening all the doors and windows so those things stop screeching! Cheers! Chris

@@MakingStuffwithChrisDeHut "baking plate" sounds plausible to me, thanks :) OH NO! No fire alarms ... anoying loud ear-penetrating sounds, terrible. Maybe I'lll send you a picture of our pizza, so you can get an impression - but dont get tooooo jealous ;)

@@tomek3633 Definitely share the photo! It might motivate me to make and cook a proper pizza instead of eating a frozen pizza.

@@MakingStuffwithChrisDeHut check your emails and get ready to have your mouth watered :)

@@tomek3633 Oh DUDE!!!! That looks so delicious!

exactly. try using a "penalty" for every turn the road makes. that would prefer the straight roads

Good morning wktodd, I am really looking forward to trying experiments on just the SPF aspect of the ZoomTown experiment. I think it is going to be a lot of fun. However, I still have a massive amount of work to do before that though. Thanks for sharing you thoughts and suggestions, always appreciated. Cheers! Chris

Good morning, Thanks for sharing your wisdom about this. I would have never guess that it would apply to network routing as well, that is amazing! Cheers! Chris

Good morning chrismofer, That is unfortunate, maybe one of the viewers here can help with C. Personally, I am not a fan of C so never program in it anymore. Sorry I can't be of more help. Chris

Good morning peterwest1158 , always great to hear from you! That sounds like a really fun project!!!! - Well, let me be honest though, without the mistakes :-) Thanks for sharing that information about the i2c requiring pull ups. Not always needed so often they are not implemented. But when problems arise, it will ruin your day (week, month). I had a situation where the the project would run fine some of the time without pull ups. Eventually I figured out that if the power supplied isn't up to the demand, it creates problems in i2c as well. I believe it is because the weak internal pull ups are even weaker with sub-standard supply power. Thanks again for sharing you experience!!! As for more videos using MCP chips - I would like to as they are SO USEFUL with microcontrollers. I just need the time to do it. Cheers ! Chris

Good morning deadly_dave ! Thanks for sharing those ideas, all very helpful. Cheers! Chris

@MakingStuffwithChrisDeHut Good morning to you too and you are most welcome.

Good morning harryman01, Yes solenoids are a good alternative for actuators. However, in this case, pneumatics were the best choice especially since I already had most of the components. There is one specific actuator that pushes the spindle locking wrench forward. That one has to stay powered the entire time while trying to advance as another actuator tries to engage the socket with the collet nut and ultimately turn the spindle until the wrench can engage. Not all solenoids can tolerate long On-Times whereas the pneumatic cylinder can stay active for days without worries (of course something else would be rally wrong if that happened!!!!). Cheers! Chris

Good morning JohnWaller-i8z, Thanks for adding that bit of Wisdom! Cheers! Chris

Alternately, You can use smaller shrink wrap and use 2 screwdrivers to stretch it out first. It'll stretch to about double it's original diameter and then it should shrink back enough to wrap the wire.

Good morning WizofOz65, I am glad you liked the video, I hope your project comes out great. Cheers! Chris

Good morning MrAlexanderk69, Wow, you are certainly an attentive viewer!!!! I am very happy to hear that you benefited from that video and I hope you project comes out great! Cheers Chris

Hello Tomkek! It has been a while since you posted, very glad to see you again. Yes, new tunes in hopes of changing things for the better. There have been a number of recent problems with the experiment causing me to rethink the methodology yet again. I am currently in the midst of a complete rewrite of the Zoomie program, I think this version looks a little more 'classy'. I still have this random "crash" problem that I have been working on, driving me nuts. Unfortunately the rewrite has not fixed it nor has it helped me getting any closer to it. However I keep plugging along on this crazy project. Anyway, good to hear from you again! Cheers! Chris

@@MakingStuffwithChrisDeHut hahaha, I experienced this state a lot in my life ... rework and improve, sometimes rewriting the whole code - but it is always better than before. So, keep on and cheer up, everything will be all right ... zoom-zoom ...

@@MakingStuffwithChrisDeHut and yes, I have been on vacation with my girlfriend. We visited the island of Ibiza and used our low-level skills in spanish language. It was nice and warm (27°C) and when we flew back home, we had 7°C ... brrrrrr ... cold germany ...

@@tomek3633 Thanks for the encouragement and sharing your experiences with these "rework" situations!!
