Electroids VS MintyBoost!
Hey I wanted to make both kits, the Electroids and MintyBoost!. Does anyone know which resistor is used in the Electroids kits? It doesn't specify on the site. Thanks!

My guess is that it's a series resistor for the red LED. If it's driven from the 5v line, it's probably 150-250 ohms or so.
If you don't need the LED, you probably won't need the resistor. From the description, as far as I can tell that kit is a 7805, a switch, and a battery clip.
Any reason you want to make both kits? The Electroids kit is cheap but probably won't perform very well at all. 9v batteries have very little capacity, and the use of a 7805 is going to make it incredibly inefficient. (Basically halving the effective capability of a 9v battery to charge anything.)
