I have spent endless hours searching for the best and most reasonably priced components from around the world.
Below is a list of components used to create the MIDI controller. The cost for this project is based on the components needed for the MIDI controller. Other tools such as a soldering iron or a power drill, or common components such as solder and wire aren't included in the final cost.
Resistors provide resistance to current flow. The amount of resistance of a resistor is based on its value.
My materials list for the project included: - 1 Altoids tin (or any suitable sized project box will do) - 1 4xAA battery holder - 4 Rechargeable AAs - 1 Solar cell (cannibalized from an outdoor garden light) - 1 DPDT Center-off switch - 1 150 ohm resistor - 1 Rectifying diode - 1 power cord (cannibalized from an old cell phone charger) - 1 PSP power adapter (Radio Shack part #274-1532) - 1 Green LED in holder - Electrical tape - 1 12-pack of bee... soda - Snack of choice (anything to warrant eating all those altoids!)
When studying for my ham radio test, I found that one of the things you need to learn is electronics. I had several books available, all of which assumed you either *liked* the topic or had a knack for it. I also had two teachers who thought electronics were wonderful and easy.
