OK now that it is all built and ready to go lest test all the circuits. Hook it up to a meter and check each switch. If all the switch are off and you...
OK so I have a old DEI 555t module laying around. It is a module for a remote starter system for a GM. So I saw the Hack it contested and want to make something for it. So first thing was to get the thing open and see what I had to work with. So grab a small screw driver and a pair of pliers.
Step 1: Its Open
Now that we have cracked the case lets see what we are working with. So I see we have 10 switches, 10 resistors, 2 relays and some wires. Hey here is an idea. Lets make something were I can pick a resistor on the fly. Well I don't need anything that is not a switch or a resistor. Lets get rid of what is not needed.
