| | | | | [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... | |
