Catching up on Electronics Projects

I’m behind on a bunch of electronics subscription boxes and projects, so I’m just going to list out a bunch of stuff. None of its worthy of its own post anyway.

One of the projects for HackerBox #0023 was to build a custom antenna out of PVC, copper wire, and glue. I did a pretty piss poor job of drilling my holes in a straight line (as you can see in the picture), but I connected it to a microcontroller and was able to scan for Wi-Fi networks in the area. Success?

I need to make more time to work with the pan and tilt system built with HackerBox #0024.

The camera that came with the project can only do 640×480, which sucks. One of these days I’ll connect the system to a Raspberry Pi and use one of my unused Pi cameras instead. Would be neat to mount at the front door to track anyone who comes to the house when I’m not home. The face tracking stuff is pretty awesome, even with the shitty camera. Here’s a really rough video of it.

I had to modify the code a lot to get everything working and I put it all on GitHub. If I work on this project more I’ll update that repo.

There wasn’t a lot to do with HackerBox #0025. It was mostly a soldering and look at the blinky lights project. Here are the 3 badges I made. I turned the star and rectangle (with a “Let’s Party” sticker in place) into pins and gave them to my nieces.

The skull badge has a buzzer on it, so I wrote some code (it’s on GitHub) to make it play the Star Wars theme and display some light animations.

Over the holidays I messed with AdaBox006 a bit. The 38 I posted on my birthday was a light painting taken with the Slow Shutter iOS app. I got it the light paintbrush working on both the Circuit Playground classic via a customized Arduino sketch and on the Circuit Playground Express through MakeCode. Both are available in the adabox-006 repo on GitHub. Using MakeCode is a fun way to program and I think it’s going to change the way people learn. Look at how simple and visual that version of the program is…

I did solder everything for HackerBox #0026 and verified some of the functionality, but haven’t done much with it. It was one of the most fun projects so far from HackerBoxes because of how many components were on this PCB. I find soldering to be so relaxing and satisfying.

I added the code for the temperature sensor I mentioned and showed in my post Why Are Thermostats Still on the Wall? to a new dht11-low-pass-filter repo on GitHub. Very simple, but useful.
