    ISO a particular switch. Don't know what it's called/to look for

    Probably a standard micro switch. Most have changeover contacts to suit whatever application. In your case you would possibly mount the switch so it could be operated by a hinged platform using the common(C) and normally closed(NC) contacts in series with the pump. I am assuming here that the...

    Attiny85 and unrecognized HIGH levels

    Are you using 2.4g system? I have seen reference to using the servo signal from these in the past, just cannot remember offhand what it was. Think I'd be double checking the commercially made boards though.

    Actulator/Solenoid Help

    Idea of the spring is to allow servo to travel to the set position. If not, the feedback internal pot will be telling the motor to "soldier on" and it will be sitting there buzzing it's head off trying to get to the set point. Also allows for a bit of leeway in the setting of the servo position(...

    Motorcycle Electrical System Resistor

    Can you show the wiring diagram you have? I found one from a '78-'79 model but there are many variants (UK, Aus, USA etc. etc.) From what I can make out it is the pre-CDI with standard coil ignition and a run resistor (similar to Toyota cars and many others). Idea is to run an 8v coil (or...
