Jeri has made educational tutor videos, which are easy to digest and assimilate. Good for Hobbyists and Students and refreshing for the Professionals.

Batteries - A to Z of Electronics - The history and technology in batteries. Ampere - A to Z of Electronics - Ampere is a unit of measurement for current and was named after André-Marie Ampère.

But, here is the Amazing part, She is demonstrating a Homebrew NMOS Transistor. This is the DIY Spirit!



Homebrew NMOS Transistor Step by Step - Jeri shows step by step how to make a transistor and at home with a kiln, Whink Rust and Stain remover, Emulsitone spin on dopant, ebay wafers and vinyl stickers.

A very slow 0.. 5 Volt fader

A circuit that generates a voltage that rises slowly from 0 to 10 Volt and (when a switch is flipped) slowly back to 0. The request did not pose much restriction on the wave form, but a rise / fall time of 30 minutes should be possible.

I got a mail question, which i logged here Long Duration Linear Sweep or Ramp Generator. The above project could be an neat answer.
