Recording Sign

An ATtiny85/NeoPixel based blinking red Recording sign for the studio…

I recently made a few “Recording” signs for Brown Dog Gadgets so that when we are recording or streaming no one opens the doors to the studio. This is one of those projects where I thought about it too long instead of just getting busy making it. And of course, like everything, there’s the issue of it being “good enough” versus being “done” and yeah, I just need to find a middle ground between those two things.

I did a quick design in 2D so I could laser cut some 1/8″ Baltic Birch plywood. I didn’t put calipers on the wood so the fit was a little tight, but nothing a few minutes of sandpaper couldn’t solve. Also, since I painted the pieces it slotted together fairly tight so I didn’t even add the 3mm hardware I had planned on. I’m pretty sure if it falls off the wall there’s about a 50% chance it’ll stay put together versus coming apart. I’ll call that a win.

Josh and I talked about using an ESP8266 so we could control it from the studio wirelessly, or just running power to it from within the studio but in the end I just went really simple (hey, it’s version 1.0) and there’s an ATtiny85 programmed using the Arduino IDE to just blink a string of NeoPixels on and off in red. Simple works and usually gets done… eventually.

Who knows? Maybe I’ll make a version 2 that is controlled via WiFi and use matte paint instead of gloss and actually design in an on/off switch hole instead of drilling it later. Stay Tuned!
