Videos about tech and tools as seen by a software developer with a focus on Embedded devices. I build IoT hardware, design electronics and write software as my daytime job. I also teach every now and then. You'll usually find me @ Bitraf in Oslo, Norway.
This channel serves as documentation for my projects and as an experiment in making somewhat better videos than I've done in the past (as in: just dumping random stuff). I'll post tutorials and tidbits about various technologies that I play around with and maybe also some work related projects. The aim will be to post stuff that can be useful to others in some way :-)

Setting up HiveMQ Community - MQTT Broker
มุมมอง 7K3 ปีที่แล้ว
I couldn't find a guide on how to set up the Community version of the HiveMQ MQTT Broker, so I figured I'd make a simple video showing how to install and set it up on a brand new Droplet on DigitalOcean. For many years I've been using Mosquitto, but setting up Websockets is quite combersome. HiveMQ on the other hand is easy to setup, has good documentation and works just as well, so why not use...
First iteration of the pcb for my SMD hand soldering workshop
มุมมอง 1374 ปีที่แล้ว
Some of the largest components are missing (I just bypassed them) as they are stuck in China (due to Chinese New Year and/or the Corona virus). Most important part - the board worked - even the tinyest component. It took 3 tries to get that right though...
Jinhan JDS6052S Review - 50Mhz portable Oscilloscope @ $100?
มุมมอง 7K4 ปีที่แล้ว
I've been looking for at portable Oscilloscope for some time and now that I'm working from my home office every day (thanks to Covid-19), I miss having some of the test gear I have at home. So what can I expect from a handheld Oscilloscope and did I select a good one? tl;dr I'm pretty sure this one will do the job. It's not a huge benchtop scope, so it packs away easily and can measure all I ne...

Short vid showing the process of making a pair of leather slippers using the laser cutter @ Bitraf, Oslo, Norway. I'll do a writeup on the details later and post here.
Getting started with Pneumatics - the Basics
มุมมอง 183K5 ปีที่แล้ว
For a customer project I need to use pressurised air and pneumatic actuators/cylinders. Having little experience on the topic I did what I usually do - I read up and look for good videos that explain what I'll need. I couldn't find a good introductory video covering what you need to build a pneumatic setup, so I figured I'd make one myself that explain the questions I had a few months ago. Peop...

The replacement for my Reprap is now ready. It takes up much less space and has much less deviations in walls of the prints. It's basically super-tight? Very happy with it and glad I did the swap! Here's a timelepse of the build with some tips and hints I discovered while building. ¨ Music: "Almost Happy" by "Kim Jong Chil"l is licensed under a Creative Commons License.

Why I'm dismantling my self built 3D printer (Requiem for a Reprap)
มุมมอง 5875 ปีที่แล้ว
At 4.5 years, this is my longest running personal hardware project. I've learned incredibly much about building machines that "just work" and I've taken the project as long as I feel it makes sense. Since my focus these days are on electronics and IoT hardware, 3D printing is now more of a tool for me. But why swap out a 3D printer that works great already? In this video I'm summarising the pro...
excelent explanation
What size of this pneumatic cylinder?
what do you call that connectors you used which controls the exhaust port flowrate and the inlet port flowrate?
Hi! That would be a "pneumatic muffler" or "pneumatic exhaust filter".
very helpful ❤
Very helpful thanks. 👌
Very informative.
Sake of it "tanks" for compressor systems are often reffered to as receievers, tanks are often related with hydraulic systems at least if you're in the UK
I’m looking to make a prop electric chair and need something to make the dummy shake. how would I make the cylinder automatically open and close without having to press a button
Sure. This is fairly easy to do with a microcontroller like Arduino. Just search YT for the keywords Arduino and Pneumatics to find many. James Bruton is one of my favorites th-cam.com/video/d7ErG5ecO2s/w-d-xo.html but check some others as well that go more into the details? One thing: many of the examples I found are using Relays. Keep in mind that mechanical relays don't like being turned on/off very fast, so it's often better to use an SSR instead?
Hiya mate I'm just getting into this sort of thing & I'm going to make a working model of basic hydraulics system so I can show it to my friends & I'd like it if you could give me a list of what I will need to get & anything else that you think would help me with it then thank's for that one jonboy
Heya. Just check the description for links. So many asked me for this, so I added them. This isn't hydraulics though as that would require a fluid in the lines. Same, same, but different?
I like 2ft piston speed and 5kg body,and dc eletrik
A little unclear to me, but just get some gear and get started and you'll find what you need?
How to Setup The SSL Cert for websocket (WSS)??
This depends a bit on your server setup. Just search for the operating system of your server (i.e. Ubuntu / Debian) and SSL setup? Maybe also throw in LetsEncrypt in that search for a free solution?
Hey so I got some Tailonz pneumatic fittings, solenoid valves and such the 1/4 NPT. I have no idea how to connect that to a compressor. Part wise I can't seem to find anything. Is there any recommendations?
Heya. I have no idea where in the world you are, so it's hard to offer specific advice. But - if you go to a proper hardware store that sells pneumatic tools & fittings, they can give you advice. Bring a valve to explain? (And no - Harbour Freight is not the kind of hardware store I think about here. You'll need somewhere that knows more than selling cheap stuff)
I want a pneumatic animatronic!
I want to bulid one!
tysm for this. vex robotics' new game introduces pneumatics so I needed to find an explanation vid
I always get confused because i always think if i want the rod end to come out slower i need to adjust the flow control on the closed end and if i want the rod end to go in slower i neer to adjust the flow control on the rod end i must be lookint at it as air coming in instead of air exhausting out
THANK YOU!
How would a steam powered 3d printer work 🤔 steam produced by a on demand water heater, or by cooking
I love the idea! Please build one! I'd use a "boiler" a kettle of pressure like on a steam train. You'll have to constantly adjust pressure and have emergency valves in case pressure gets too high.
Watch at 10x lol - but thx for the vid
Thank you for this video.

Good
Thank you for this video! How loud is your compressor?
Not so loud that it scares me? The most important is to have a pressure chamber so the compressor does not have to run all the time. Beyond that, you pretty much pay per decibel of reduced noise so it really depends on your budget. Any cheap compressor will be loud basically.
How did your ball launcher turn out? I wanted to make something similar that would be able to shoot a basketball ball up to 20-25 feet. Would everything just need to be sized up to handle that?
It actually ended up beeing opposite of what I thought. If you try to blow something inside a tube, it'll fail at some point. The ball will stop inside the tube. What I had to do was to use under-pressure. Turned out great and have been running all year for 4 years at the museeum by now. They're very happy with the installation.
Now if only eBay sellers would specify which connectors to buy for their cylinder I would buy one already for my project.
@Maketronics thank you for this video I followed your instruction but I have the error "“Connection refused: Not authorized” I want to mention that I am running Windows OS
Hi Yusuf. I never tried setting it up on Windows, but it sounds like you've added the user extension? (RBAC) If so - are you using the default username and password from the comments? (user1/pass1) th-cam.com/video/p04NqXDlRE4/w-d-xo.html
Boutta make animatronics with this 😀thanks very useful
can you please share the pump details that you used for this demonstration
Hi. If you expand the Description here on TH-cam, you'll find the details ;-)
Make a fist with phenmatics
What size of cylinder did you use?
Humko chahiye
What the power supply? 12v ?amps ??
Hi. This depends on your specific device. The one's listed under the video are 12V (as written), but you'll find others as well. 24V is a common battery on trucks/lorries, so that's also common. There's also 110/230V solenoids available. Amperage is directly related to how strong the solenoid is. These small one's won't pull much, but look at their datasheet and you'll find what you need.
Hi can not using a air tank to lift weight weaken the strength the cylinder not lifting one side off my chassis im only using air pump 7.4v lipo battery and lego air cylinder
Sorry. I have no idea what you are trying to achieve with your LEGO here - weak cylinders or not ;-)
@@JensChrBrynildsenthe lego ones i have are weak to lift my chassis but the 16mm bore mini peumatic air cylinders i have lift it
@@TW39 Ok.I still don't understand your question though? Do you wonder how to get more "pressure/lift"? The easy answer is to not use cylinders made for LEGO since there are obvious limits to how much pressure a plastic cylider can hold.
i know now have to use 16 bore in diameter peumatic air cylinders to lift the weight im new 2 this
Hey nice video! I was wondering how powerful of an air compressor do I need to move the piston?
Most small compressors will give you at least 8 bars of pressure and that's enough, unless you are moving something heavy. Look for a compressor that has a tank, so the motor does not have to start all the time?
Hi, can we control the position of the piston extension via 4/3 solenoid valve?
Nope. For that, you'd probably use an electronically actuated device with position feedback. Look for a linear actuator with position feedback?
I wish you would show us video of the cannon build.
Im making a pneumatic vegetable cutting machin for my final year project, what kind of air compressor should i get?
I would need more info on expected cutting speed, the size of the setup and much more to advice on that, but just start with something that has a tank? If that runs out of air, you'll know that you need something bigger.
Can I change language my device is in Chinese
Yes. Just follow this video th-cam.com/users/shortspmgMpJFuZKA
Hey so I'm trying to make a portable system and Im considering CO2 and/or paintball canisters of air, any suggestions?
You could totally do, but it seems a little wasteful? Will be expensive in the long run :) This guy has a good explanation of his setup th-cam.com/video/wCxJ12s1-cI/w-d-xo.html and CO2 makes much more sense than air.
Thank you so much, it helped me a lot.
Would you use more air keeping single acting open for 5sec then using dub acting ?
Sorry for late reply. This would depend on your setup/connections, but it does not have to.
Excellent explanation thanks a lot.
Very interesting video - thanks - I've been through exactly the same process (still ongoing) - having started with building printers in 2012, I now use Prusa models. I've dismantled one, and am trying to use up 3mm filament before doing the same with 2 more printers. It's always a dilemma with projects - however much effort and thought has gone into them, if they are no longer used they just take up space! It's encouraging to see someone taking a sensible approach... (Mortimer Rhind-Tutt)
Pretty good demonstration. You helped me a lot, thank you!
Good video, thanks for posting. Where did you find those small actuators? I need something just like the one way spring loaded you have.
Hi Evan. I got mine from AliExpress, but if you're in the US, it's usually faster to get it from Amazon.
it can power a whole building bro it does heat ac fans temps
Hey do you know if I can use a mini compressor
I have found that some of these are not be able to hold the pressure at max for more than a few seconds. Another problem is that it will produce noise continuously. If the noise is no problem, you can give it a shot. I would recommend getting one that has a pressure chamber though - even if it's just a small one. Start with a small that you treat well and then sell it when you find that you need something bigger?
@@JensChrBrynildsen they you might have a Idea what for brand I need to look for?
Are you from Norway?
Yup 😉
So the most important is the first point at 15:27 as exactly this feature is what the sense of handheld scopes should be about.
