My little setup

Finished my first DIY PCB project
 | I've used an online PCB company before but this time I wanted to try to do it myself. The design is based on Don Lancaster's Low Cost Keyboard project from 1973. Link to scans of the Feb 1973 article in radio electronics magazine I had to 3d print the key caps and stems but I think they came out ok. The springs are made by using a drill to wind piano wire around a screwdriver along a spiral path. The contacts are foam tape and aluminum foil which worked surprisingly well. I still need to work on adhering the film to the PCB and engineer a more precise way to make slots and vias with a cordless drill, but everything works as expected! I'm pretty pleased with the result. Next step is to make a "full" keyboard. [link] [comments] |

Roast my circuit
 | Hi guys, Happy to get some feedback on this climate control project i put together. Constructive feedback preferred, but reddit-style puns and dad jokes also ok. The code is in: https://github.com/sdesalas/esp8266-climate-control No commercial motivation here. Just hacking together a circuit for kicks. Thanks!! 😎 [link] [comments] |
My First Full Color Silk Screen PCB
 | It came out really nicely - the keyboard is silk screen printed over capacitive touch pads: It looks even more impressive in person. There are a few more details here, but the actual process of getting the boards made was pretty painless. Just needed to send a PDF with the artwork and some guidelines on where it should be printed.

Annual Clock: Experience Time on a Wider Scale!
 | My first electronics project was an annual clock based on something I saw on kickstarter a while ago. The clock slowly advances ~1-degree a day and you can see the year progressing in a whole different way. Just in the 3 weeks I've been working on it has advanced 20-degrees and it gave me an interesting perspective on what % of my year went by in a very intuitive way, It was a great learning experience and got help from this community too--thanks! If anyone is looking for a simple project that has a fun deliverable, take a look. I think it'd be perfect for STEM programs starting at middle school. https://www.instructables.com/Annual-Clock-Experience-Time-on-a-Wider-Scale/ I am definitely open to feedback for any part--hardware, software, instructions, etc--so please share anything that you think would help get more people to be successful with projects like this!

Made this absolute abomination while trying to debug why the LSE wasn't working on my newly developed STM32 dev boards... Took a bit of trail and error adding caps to find a value that worked! RTFM, I learned the hard way how to spec the caps for an...

Cute little radio kit.
 | No instructions except a few pictures online. Cheap kit. The yellow caps had polarity printed on them so I checked which mounting holes went to ground on the board. No hints printed on the board to help. Works good on a battery but plugged into a cheap car charger it makes nothing but static due to the dirty power. [link] [comments] |
Built 1 micron precision measurement tools
 | I'v built a circuit that use PIC mcu and CCD to measure the width of things (tube) without using micro meter. the result is quite good. However there's a little point I'll improve later. just to make it best tools. [link] [comments] |

28v DC controller
 | Average Joe here trying to fix an electric lawnmower while trying to learn a thing or two in the meantime. Mower has three components - batter, DC controller, motor. Using a multimeter, I’ve determined the batter is fully charged. Connected battery to DC controller and measured air rent on other end. Nothing. I’m presuming the DC controller is not functioning. If this logic holds. I’ve searched for a replacement DC Controller to no avail. Is there a way to instead recreate controller that can still be functional to the mower?? Maybe this controller is proprietary in some way? Again, not an electrician or engineer if any sort. Just trying not to problem solve (which for me is fun in itself). [link] [comments] |
