I have had this old DOD Flanger kicking around in my parts box for about 10 years. I finally got around to testing the mods on it, and WOW! It’s a killer. From added LFO tones and noise to delay-like repeats The mods are pretty simple, you replace the 3 internal trim pots with comparable-value … Read more
When I saw the midi speak kit online I knew I had to have one for my Speak and Math. The circuit-bent Speak and Math is already a ton of fun to play with. Sick, sputtering, looping glitches, word fragments, and random number strings are common, so getting it to trigger along with your drum … Read more
The Noise Ensemble is an extremely noisy delay that can easily be pushed over the edge into self-oscillation. Based around the PT2399 IC; it has a built-in VCO, 2 op-amps, and 2 low pass filters crammed into a 16 pin dip case! It can get very loud! Check out the datasheet. I have built more … Read more
Here is a handy diagram for circuit bending a Toysmith Megaphone Voice Changer. There are a couple more mods you can do to this bad boy but the ones pictured are the key to getting sound in and out via jacks, as well as pitch and feedback loop. These are really versatile in the studio … Read more
FROM 2012 : This is a project I started a few months back for a friend who is looking to sequence 8 Korg Monotrons for live performance… once the Monotron Delays get delivered I will most likely follow the great advice, directions, and tips at Steve Woodward’s site, he has compiled most of what is … Read more
Super simple OPTO LFO for a friend who was looking to design his own enclosure based around some kind of electronic noise toy. Here is an even simpler drawing of the schematic. (I mistakenly called the glass insulator I used to diffuse the light and inductor, too many beers before filming).
