Unusual functions of cheap parts

As an addition to the various mentions of common diodes as varactors there is a well publicized British design for a frequency tripler that will put out 2 watts at 1.3 GHz and uses five 1N914's in parallel. I once built an HF transceiver that used CMOS logic chips for all functions except an audio low noise amp and a voltage regulator...with further thought those two could likely be done with CMOS logic too. At least the audio amp, this is nice to build with some Inverters (4069) with resistive Feedback. -- Martin |
