| | | | | Video Appetizer https://youtu.be/XsFSDM1pgMA TLDR I built a shortwave radio receiver from scratch using only cheap and easily available components, i.e. standard transistors, op-amps and 74xx logic chips. No typical radio parts - no coils, no variable capacitors, no exotic diodes. This project is easy to build and gives you a hands-on experience with radio technology... | |

| | | This project is a little old, but now that I have some time, I thought it would be nice to write it up! The device has been serving me well for a few years now. Being somewhat red/green color blind, I've always had trouble reading through-hole resistor color codes (though I often wonder if those with full color vision have it much easier - some resistor bands are so 'muddy'!) I make do with labeled pouches holding my resistors, and a multimeter to double-check. The multimeter is so slow. Surely it shouldn't take seconds to sense a resistor value! For years I dreamt of making a faster resistor measuring device with an instant readout. The 'final straw' that pushed me to actually do that was that I bought a beautiful old metal Akro-Mils cabinet1 stuffed with o... | ||
