I bought 200 Raspberry Pi Model B’s and I’m going to fix them

I'm using one right now to build a Fireman Sam dispatch console for my son. Lots of leds and buttons. An arduino would be better, except I want it to play MP3s so the computer voice can tell where the fire is, beep the right beeps, etc

Neat project! There is a small, inexpensive MP3 player board called DFPlayer that can be controlled from an Arduino and probably would work well for similar use cases, if using a full Pi isn't an option.

That’s an excellent idea. Will you be writing a blogpost about it (please please)!

I do something like this every few months, and I've never tought them worthy a blog, to be honest.

It isn't particularly complicated. Base is a strong enough cardboard box from the local supermarket. I took screenshots of the console from an episode and cleaned them up with krita.

Electronics is a matrix where some rows have leds abd others buttons.

Software low level scans the matrix and drives leds and checks buttons. High level a state machine that changes state based on button presses.

I mainly us whatecer I have lying around at the moment, and don't spend much money on components.

The thing before this was a lego based crossroad with leds and an arduino
