I started building my own electronics as a kid. In 1989
parent's brand new $400 VCR and they weren't too happy about it (even
though I did put it back together) so they started giving me
electronics kits to play around with. Before long I got pretty good at
it and even started developing my own circuits. Now days I mostly build
things because I either can't find, or can't afford the thing I'm
Here's a sample of some of my recent projects.
The speakers built into TVs and projectors are really,
horrible. In here I show you how to build a small pair of self-powered
speakers to give your ears a break.
Optical S/PDIF digital-to-analog converter based on the
Cirrus Logic CS-4338 DAC and CS-8416 audio interface chip. Works with
all common sampling frequencies and resolutions, including
32/44.1/48/96kHz at 16 and 24 bits.
I have a real fondness for tubes, when it comes to hi

music. This is the preamp I use everyday, featuring five tubes, a
12AX7/6DJ8 phono stage, two 6DJ8s as a line stage, and a 6BY5 as a

My thoughts on why tube gear sounds the way it does.

electronics; how to read a schematic, different types of components,
