I'm building a BEAM blimp, and this is my first electronics project. I'm really having trouble identifying the parts I need to build the schematics I found. This is for the head only, as I plan to build it first, as a "warmup." Here are the schematics:

Hi Geo,

From your schematic:

The main chip is the 74AC240 octal inverter, it has 20 pins, each pin input and output is identified on the schematic by the numbers.

The other parts are:

photodiodes or light dependant resistors
a few capacitors and a few resistors

Please ask if you require any more details.

Blimp sounds great! care to elaborate on your plans?

Tom
