If power consumption wasn't an issue, I would have picked the WS2812 as well. They offer so much flexibility with color selection. Thank you for posting the photos and the video!

Nope, unfortunatly instructables never bothered. As a workaround you can create manually a normal link (@3LRusS1T0) and message the person.

Ha, yeah the LED soldering part is "not easy" to say the least. I've tried a few different ways and because I was running out of time I just went with the "easiest" method I found. That said, your method seems a lot more straight forward. It systematically solves the alignment issues and should thus be a lot faster too! I think I have one half-build spare PCB left, I'll have to try it myself :D It's a shame that you can't pin comments, but I've added a note to step 13.The orientation of the LEDs is marked with a tiny dot close to pin 1 in the silkscreen layer. For diodes it the de-facto standard that pin 1 is the cathode, but I admit that I should have mentioned that somewhere. It should be possible to auto-detect the polarity of the LEDs at runtime, which I'd properly…

Wow, this version looks even more gorgeous than the smaller version. :DWish you best of luck in the contest!
- nqtronix commented on nqtronix's instructable PCB Christmas Tree Card
Many LEDs will be suitable as long as they are roughly the same size and have two independent chips inside. I strongly recommend the red/green combination (not yellow-green) because the animations are optimized for those. From mouser these types should be usable: https://mou.sr/3aGCuSk. The generic ones I used are from aliexpress work ok as well.

Wow, your designs get more and more sophisticateted! Even though I do not need such a device (or know anyone who does) I do like reading the technical aspects behind it :)Oh, and one more thing: Unless you like etching PCBs much, consider getting them manufactured. elecrow and jlcpcb are both good and the size 10x10cm costs less than 25€ shipped.

I couldn't help but give the robot some eyes that glow when you've awoken him (by gently petting his head) :DTwo LED are directly connected to a TTP223 touch IC which is powered from a CR2032 coin cell. Aluminum stick tape masks the eyes and prevents light from coming out anywhere else. Had to scrape down the backside from the cardboard to make it a bit more translucent. Turned out really well, I think :)Happy Halloween 🤖

- nqtronix commented on lonesoulsurfer's instructable How to Make a Optocoupler (Vactrol)
Interesting part, I didn't know they make them with an exposed base connection.
View Instructable »You have now made your own optocoupler which will work just as good as any store brought one.Although your build does provide galvanic isolation, it is not a substitute for an optocoupler. Not only will the transfer function be different (ie. the same input current will not have the same effect on a real optocoupler), but it will be also about 100 times slower. Typically optocouplers are used in high voltage applications as a safety measure and thus must have a guranteed voltage rating, which your build doen't have either.So yeah, to understand the concept this is fine, but for real applications it won't work in the best case or be a risk for electric shock in the worst case.

I've seen the original years ago and have to say that your version is a huge improvement in terms of the overall look and feel. I dig the "speaker grill look" on the top of the box, it makes it seem like a miniture version of a professional keyboard :D

The distance between high and low voltage is IMHO too small. If the buttons on the front panel are rated for mains voltage, it should be safe to use unless you use the reset button while connected to the mains voltage.I've attached a picture to illustrate my concern. The image is from Ken Shirrifs blog with more detailed explainations: http://www.righto.com/2016/03/counterfeit-macbook-...

I totally dig this unusual lamp shade design. The abstract shapes work really well together with the light pattern it generates.Do you still have the print file used for the paper mock-up in step 12? I don't have a 3D printer, but I do have some spare matte acrylic glass that might work instead.
- nqtronix commented on WilkoL's instructable Tuning Fork ClockView Instructable »
Huh, I never though about the acoustic noise a low-frequency oscillator generates, but it's so obvious in hindsight. I guess that's one advantage of the modern 32kHz watch crystals beside their reduced size.Nevertheless I appreciate you build as it is. Being able to see what makes a circuit tick - in this case quite litterally - has always a certain charme to it. So thanks posting this :)

Thanks! I actually planned on adding a case, but didn't get around to try it in time for the contest. Right now one must pay attention to keep enough distance to other elctronic devices.I try to avoid batteries for non-portable devices because of the added complexity and size. If I'd do this again I'd spend more time on the design before prototyping it, but I simply did not expect noise to be an issue.

Despite all this negative feedback I have to admit that the re-design does actually look quite good and intuitive to use. So this update is MUCH better than the last big update two years ago and I'm glad you learned from your mistakes. Cheers to whoever implemented lazy-loading for the images, that is really helpful for browsing on mobile.The most annoying thing was the removal of the recent page, but you're already about to fix this. The other thing I'm missing is the general community button. Although I do not use it often (and I'm sure your statistics indicate similiar other user behavior), it is important for this general kind of feedback. Can't you just put a "Projects" and "Community" button on the start page, too? The projects button could take you to the "…

@MaclskThanks for the info. I vaguely remembered a similar design I've seen a while ago and was curious why it was featured again. If you want people to make use of your inventions as long as they give proper credit, you should considering using a CC NC-SA licence or similar.@JLGG_3D Come on, you take like 90% of the work from someone else, fail to mention it and then have the audacity to enter a contest? That feels like a violation of the unwritten makers' codex.

Indeed. This is especially true if you require parts from overseas and/or custom made parts such as PCBs. It's not uncommon that a single project takes several months from the first idea to the final result.

Pretty cool! Its refreshing to see how complex projects can be build from so few (mor or less) discrete components. While it is likely impractical for daily use, I like this instructable for the educational value alone. It proves that even without a micro one can do soo much more than what seems possible (at least to me, a member of the microcontroller generation).
- nqtronix commented on _Gyro's instructable Bike Wheel Lights Hack
When I clicked on the thumbnail I thought this was done with either EL-wire or some LED strip, either would have been a nightmare to mount and wire up. So I'm pleasantly surprised with the glow-in-the-dark pain and UV LED solution you've come up with. As a bonus, the light is way more even than it would have been with EL-wire or an LED strip. Thanks for sharing!

Hey, thank you for showing your build! I did not expect a "light sesnsor" diode to work this will, but your resuslts are certainly usable for many applications. Maybe the reverse voltage was high enought to bring down the effective capacitance significantly. Using batteries is a good idea as this will solve much of the noise issues.
