For one of my recent projects, I needed a way to control some lights powered by a 120V household wall socket. Rather than reverse-engineering some commercial “smart outlets” for the task, I decided to try and do this the old-fashioned way by embedding relays in electrical boxes.
So far the hardware side of the Adalight setup has been a nest of wires on my desk, with the Arduino on a breadboard and the power running through a terminal block. Now it’s time to wrap up this project by getting everything off of the breadboard and onto a dedicated PCB in its own custom case!
Just in time for the holiday, I finished work on my replica Reaper mask from the video game Overwatch!
The base of the mask is a wonderful 3D design by Ricardo Salomao, which you can download here. I wasn’t originally planning on building a Reaper mask, but I found this fantastic model and just had to make it.
While the final version of the footwell NeoPixel project calls for a long strip of ~60 pixels, most of my time is going to be split between programming at my desk and testing the pixels’ response to telemetry from the car. I didn’t want to have to wrangle a large strip every time I wanted to test an idea, and I figured most of the patterns for the 60 pixel strip could be replicated on a shorter one.
My solution is this small prototyping board. It’s a 3D printed part with mounts for an Arduino Uno, a small breadboard, and a NeoPixel stick. The NeoPixel stick is a nifty PCB with 8 of the same type of RGBW leds as the strip I plan to use, and includes input/output pads and a resistor for the data line. The breadboard lets me wire a 1000µF capacitor to protect the pixels from voltage spikes and allows me to hook up a second power supply if I’m reaching the power limits of the Arduino (which I should note is absolutely possible if you’re using all of the pixels at full brightness).
For the inaugural post on the blog, I thought I would post a small completed project that I made awhile back. Last year I finally purchased a 3D printer of my own – a Printrbot Simple Metal #1403. The printer itself works fairly well, but it sorely needed a light so I could see what was going on under the extruder head.
