Thinking of building the Moog VCF I posted yesterday? You might want to check out this post about using Cupric Chloride to etch PCBs.

Usual disclaimers apply.

Moog Low-Pass filter clone

November 20th, 2009

moogFilter_cc

Robert Moog, may he rest in peace, invented a legendary voltage-controlled filter (VCF). It’s the low-pass filter that gives the MiniMoog its characteristic sound. YUSynth has published the schematics, parts list and PCB layout for the MiniMoog VCF.

How to drive a RGB LED with a PIC

This simple project shows you how to drive a RGB LED with a PIC. Interesting, colorful, and expandable. With a little work, you can replicate the Ford Focus’ best feature with this: its configurable interior lighting.

How to Make Printed circuit boards

So you’ve designed a nice circuit and laid it out on your trusty breadboard. Time to move on and make a permanent version of it. You can always use stripboard and obtain a sloppy yet functional version of your circuit, or go all out and print your own circuit board. Homemade PCBs produce professional looking results without the overhead of dealing with a third party. An excellent option if you’re just making a few instances of your circuit.

This nice how-to shows you how to do that. Just make sure you dispose of the chemicals properly when you’re done. The sink isn’t an option here.
