Ignition Coil Testing
I started to search, the other day. Sometimes my hands hurt so bad, I have a friend that is interested in what is known as QRP radio. This comes from the old telegraph and radio what is known as "Q" signals, "QRP" means "shall I reduce power" and "QRP" operation has become a "gentlemans" agreement" sort of a contest of "5 watts or less" deal. In other words "how far can you get" on less and less power. And of course this means CW or morse code, because this is the lightest, simplest way to get portable equipment.
But the PROBLEM is that it hurts my fingers to operate a key, nowadays, and to operate a pencil!!!!
The thing is, there are more and more amateur based projects on processor based 'stuff', that is basic stamp, arduino, and rasberri pi, etc:

And Ten-Tec is in the mix, too
