Re: Mission Possible C

Re: Helicopters C

Packing peanuts work nicely too. Except, you always have to be careful when dumping them out. ;) Thanks!

Re: Exothermic Task

For this task, I'm just using a G4 Halogen bulb, a photoresistor, a TIP120 transistor, and an Arduino. It has been working reliably since December and has run consistently hundreds of times. I highly recommend this method, because it's easy to do and it is very unlikely to fail. Could you explain h...
