If your holiday festivities are lacking some flashing LEDs then you have to look at the latest project that our friend Ian from Dangerous Prototypes has made. It’s a circuit board LED Christmas tree Ornament!

"Holiday cards that blink and beep have always fascinated us. This is our hackable DIY version, made with an ATtiny13A and a few LEDs. Push the button to play a short light show in the tree. We’re sending these to friends and family this year. It’s a handmade, hackable gift, and it was a ton of fun to build."
