| | Introduction Some time ago I started a project of reusing an old, crappy toaster oven as a reflow solder oven. I did some necessary improvements on the oven, like adding a glass wool isolation. I also examined dynamic characteristics of the oven by looking at its transient response to a step input power. Everything was...

| [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.
