I had some leftovers from the zener diode video. So I shoved 16V/12A through them.
Read MoreThis PIC was rated for 3.3 volts. I gave it 16. Now I need new power leads.
Read MoreMy Canon 580EX 2 on full power is VERY bright. Bright enough to burn a hole through a garbage bag!!
Read MoreThis is what happens when you connect things backwards with 30 Volts.
Read MoreSo I recently got hold of some 2600F (no that is not a typo) ultracapacitors with an insanely low ESR of 0.7 milliohms, meaning they can discharge hundreds of amps even at low voltages. This video shows you some of the mayhem I got up to, and teaches some important capacitor formulas along the way. […]
