PCB Display Case With Overhead WLED Lighting [ESP8266] Jeremy Cook 2021-07-07 | PCBs often don't work out, however, they can be quite beautiful.

The same concept could be applied to any sort of display case/shadow box, which could be a great way to get the same sort of effect without a laser cutter or complicated mechanical assembly.3D CAD step file: github.com/JeremySCook/Laser/tree/main/cutouts/PCB-display@ 9:11 "problem with the firmware" is what I thought here, as when I flashed the board again on another build the problem went away. So not the way the firmware was written per se, but how it was transferred to my device... OTOH, I may have added another capacitor at this point, so it's hard to say. Definitely some value in trying one thing at a time if you're trying to get to the actual root of the problem.All that being said, WLED is pretty awesome - I'd suggest you give it a try if curious!

First PCB - Printed Circuit Board [WILL IT WORK?.. yes, it does] Jeremy Cook 2020-02-25 | My first printed circuit board (PCB) design, designed in KiCAD and ordered from OSHPark. PCB blinks up to 5 LEDs via an ATtiny85 chip and CR2032 battery, then goes to sleep until triggered again. Sort of a "Hello World" for PCB design.Code for 3 versions available on GitHub: github.com/JeremySCook/ATtiny85-5LEDPCBI followed along with this tutorial to figure out how to actually make a PCB: docs.kicad-pcb.org/5.1.5/en/getting_started_in_kicad/getting_started_in_kicad.html on KiCADInstructor for class I took previously was Anool. Not sure what his schedule is like, but his Twitter is: twitter.com/anoolIf you ask nicely, I might be able to put the revised PCB up as well (I don't think I have this actual design available anymore). It's pretty trivial though. Also, this video wasn't sponsored by OSHPark, or any other PCB manufacturer obviously. I did use a card with a discount code that I got years ago for the purchase, and it still worked, so that was pretty cool of them.

ClearCrawler Goes to Hackaday SuperCon 2019 Jeremy Cook 2020-01-06 | The story of how I traveled thousands of miles with the ClearCrawler robot in tow to attend the 2019 Hackaday SuperConference.

Really glad I went, and would definitely going at some point if you can. Here's my thoughts on the conference: embedded-computing.com/guest-blogs/hackaday-superconference-2019-an-incredible-collection-of-people-and-techMonoprice case used: monoprice.com/product?p_id=12184 - Case was provided for free, however, I was not expected to do a review of it. Basically, sending it was a bit of a mistake, as I requested it, but then realized I might not have time to do a review in a timely manner. They sent it anyway, and said I could keep it either way, which was certainly less trouble for everyone and was very nice of them.

Why Instant Replay is Worthless for Yardage Jeremy Cook 2019-11-29 | When a referee makes a call regarding where a ball was thrown from, or on what yard line it was caught, this is often "verified" via instant replay. As seen in this video, depending on the camera angle and height of the player, this can be EXTREMELY unreliable, especially when you need supposedly INDISPUTABLE evidence.
