Pogo Pins: Attractive Distraction or Ultimate Wiring Solution? - DIYson Lamp Build Log #9

- Welcome back to another DIYson build log, the series where I gradually overcome my fear of speaking on camera while also trying to build an open-source version of the Dyson Lightcycle task light. I really want to make this wiring alternative work, so I spent an unreasonable amount of time doing a proof-of-concept experiment to test its viability. I ended up learning a lot exploring this solution so I hope you enjoy seeing the process as well :)

Hello! Hope you all enjoy the return to the full DIYson. Lot’s of experimentation and iteration in this one!
Careful on relying on a capacitor. Of course, I would add one, it will help - but when testing, if you don't have a load similar to the light on the circuit, it will appear to fix it more than it really will. Like in your test case (at least as you showed it), there is effectively no load on current path, so the capacitor is smoothing out the 'signal' much more than it will with a light attached.
I think a solution - or an approach that makes other solutions more likely to succeed - is to move the placement of the pogo pins. At the moment they are mounted away from the point the arm is pivoting (somewhere between the rollers) - which magnifies the misalignment. If you get the pins mounted closer to where the arms pivot - the length of travel of the pogo pins may be enough to keep contact during lamp adjustments (which may also explain the positioning of the original power block @
Hi!:) You could use carbon brushes, like in electric motors. Those are fairly long lasting considerint how many time a motor turns before brushes need to be changed. They are "self lubricating" and somewhat selfadjusting, because of the graphite itself can be seen as a lubricant.
Jake is now a certified DIYson legend. Hope he makes another one for the final version.
Loving this series, your iteration and attention to detail is really inspiring! One potential alternative for the pogo pins could be some off the shelf carbon brushes intended for use with a small dc motor. These are spring loaded and maintain electrical contact to the spinning part of a motor so keeping contact with a linear smooth track should be no issue for them, they may also offer a little more surface contact area which could help with any slack or twisting in the assemblies. Looking forward to future videos!
Great solution to the wiring issue. Sounds like it will work. Must admit I didn't like the wire chain solution, but figured it's the best way considering the patent limits. But this really works from the aesthetics point of view. a DIY solution for an extremely tough issue. Won't be surprised if you get a nasty email from Dyson now that you've basically achieved their own design, but without patent infringement.
Stephen, your videos are great! As soon as you upload a new one, I drop everything and go watch it.
That moment when you have a whole set of things you want to test, with neat possible solutions in mind and you end up fixing it on the first try
super cool ideas and developments again this time, very well done for the thorough testing you did, that seemed like a ton of work.
Getting yourself very prepared to solve a complex problem and fixing it first try is so funny. This is one of the best build series I've ever seen. Can't wait to see more.
I can't get enough of this project, for real!... Your commentary ties it all together very nicely, and I love seeing and listening to you go through your creative process.
I’m really enjoying the series! I think a design aspect of the light cycle that may be worth testing here is just the location of the connection, positioning the pogo connection between the two v wheels will get them closer to the axis that the arm is twisting on. The closer you get to that axis the less apparent the rotation should be.
You could try something similar to slot car track - instead of pogo pins, they use little metal brushes to stay in contact with the track. Brushed electric motors also use, well, brushes.
RUclips just reccomended me this project, and I gotta say, I love this project and can't wait to binge all of the other build logs! About testing the pogo pins, one way you could've tested it is by putting either a small voltage (~0.5v) or a high frequency signal (around 10KHz sine wave) on the rails, and connect the pogo pins to a 3.5mm audio jack, then to a line in of a PC or a audio recorder. you can then hear or see (in Audacity or other software) the failure as drops in the signal, which sounds like when you turn a headphone jack in a bad plug, but you have much more resolution than with the method you were using.
I'm so glad you went for this design change. I suggested it in the comments of one of your earlier videos and I'm so glad you got it to work.
Just discovered this series last night and binged it all today. I am so impressed, this is a remarkable project. Can’t wait to keep up with it now!
Totally my favorite series on RUclips. I’m so excited for upcoming videos. Great work and so much inspiration for my upcoming industrial design internship!!
Awesome as always! One solution to the pins could be to have them pressed down with a spring so when they move too far away from each other the spring keeps pushing the pins down.
Another really fantastic and impressive build log. I really enjoy the way you're putting together all the different aspects of engineering yourself, and coming up with great ideas to solve problems and test the solutions to really get into the details of what's going on. Can't wait for the next one.
