My Electronics Projects/Notes
Finished Projects
A Rudimentary Pelletron |
|---|
| An induction-based electrostatic machine built from available house-hold items and pre-existing projects based on the design of a Pelletron (an improved Van de Graaff generator topology). |
555 Flyback Driver |
|---|
| I made a simple circuit with a 555-based oscillator for driving a flyback transformer primary coil with some parts that were laying around the garage. |
200V Boost Converter |
|---|
| A closed-loop 200V boost converter with a 555 clock and Schmitt trigger feedback. |
Some bipolar power supplies |
|---|
| A couple of basic circuits for generating a bipolar supply from a single voltage rail. |
Some Notes
Notes on LED Photometry |
|---|
| A page of notes on LED photometry drawing on Forrest Mims’s works. |
Basic Magnetics |
|---|
| A page of info on the basics of magnetic materials. |
Unfinished Projects/Graveyard
Low Noise Audio TIA |
|---|
| A design for a low noise transimpedance amp and corresponding PCB. Never spun out or tested. Originally intended for use with field mill E-field sensor. |
Field Mill E-field Sensor |
|---|
| A mechanical chopper-based E-field sensor (field mill). Testing failed due to 60 Hz noise in environment. |
