| | | | | 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... | |

| | | | | [AI summary] This is a detailed account of the design and implementation of a trailing edge dimmer circuit for a lamp. The author explored various components and concepts, including current sources, pulse generation, and the challenges of achieving a linear ramp for dimming. Despite the project's complexity, the author found the dimming performance to be less than ideal due to nonlinearity in the ramp and flicker in the output. The project concluded with a decision to pursue an alternative solution, such as a rotary switch, instead of a dimmer. | |

| | | | | 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... | |
