We’ve all got a box full of old PCBs, just waiting to be stripped of anything useful. [Dennis1a4] decided to do something with his, turning it into an attractive mosaic that he hung on the wall of his new workshop. But this isn’t just a pile of old PCBs: [Dennis1a4] decided to use the LEDs that were on many of the old boards, creating a blinky junk build. That’s kind of neat in itself, but he then decided to go further, building in an IR receiver so he could control the blinkiness, and a PIR sensor that detected when someone was near the mosaic.
This whole setup is controlled by an ATMega328p that is driving a couple of PCF8575 port expanders that drive the LEDs. These blink in Morse code patterns. [Dennis1a4] also used an array of DIP switches on one of the boards to randomize the patterns, and wired in a pizeo buzzer on another board to make appropriate bleepy noises.
I’d make mine more like Data’s head from Star Trek TNG. Hundreds blinky LEDs that makes it look like it’s actually working.
This guy’s website is a goldmine!
Thanks for the complement :)
Dude, That integra is amazing sir.
Looks like Borg tech :)
That’s a big conference badge. Damn..
Very cool artwork.
