Want to get your point across? Why not say it with light? This new kit lets you create your own custom LED light board using any pattern you want. The whole thing reminds me of a modern-day Lite-Brite.
The latest Open Source creation from Evil Mad Science Labs, “Peggy” gives you the parts you need to make a pixelated grid of LEDs in any design your little heart desires.
Peggy is named for her 25 x 25 pegboard which can hold up to 625 LEDs in place for your custom signs. It’s able to drive just about any LED you’d like, and can be run off of 3 ‘D’-cell batteries or on an optional AC adapter. The kit includes the pre-populated circuit board, battery pack and a photosensor which lets you automatically turn off the display in daylight. And yes, the whole thing is driven by a fully-programmable micro-controller, so you can create animations, blinking and flashing displays if you know what you’re doing.
Keep in mind that you’ll need to buy your own LEDs, and will need some basic soldering skill and a soldering iron to create your own signs. The kit is available from the EMSL Shop for $80 USD. You can also pick up a batch of LEDs while you’re there. (For those more adventurous, there’s a bare-bones version of the board without the electronics already installed for $50).
