Great stuff Sean. I'm pretty good at writing the stuff down, but I need to learn how to use my scope, and read ITMD, to make any sense of the more technical jargon. Sure, I can measure frequency, inductance, resistance, capacitance, consumption, test a tranny and a diode, but the complex mathematics and algebraic equations escape me.
I can easily use PCBexpress and Lay6, but battling with Eagle so far.
On the 99% perspiration, 1% innovation theme- there's gotta be a better way to make a 555 into a simple detector, than the generic 10mH piece of snot? Even if it takes a few extra parts? I have made a BFO using the 555 as a reference frequency, but this is far from ideal. I recently came across a 555 solar regulator a bloke made, and won an award for, so there's obviously still more experimenting to be done with this versatile chip.
Another recent thought is adapting Colin Mitchells Circuit 8 into Garys "better" 4069 BFO. I praised this circuit 8 here when I first started, and the AM radio detector I made from it still impresses me. I will be finished my Hort. Cert. this week, (I hope) and attack the electronics with renewed vigor.
