Happy Canada Day! Here is a cool LED Fireworks project by Instructables user vahid_you2004. The circuit is sort of like a bunch of LED Throwies except the LEDs are being powered from capacitors instead of coin cell batteries.

“I decided to simulate fireworks with LEDs and made a machine that makes LED fireworks.
It works simple, there are a lot of LEDs that everyone is connected to a capacitor with a resistor, the machine charges the capacitors and a timer drives a motor that strews them around.”
