I’ve been wanting to build this interesting voltage-controlled noise source for a while, and now boards are available from hexinverter.net for a modest $15.
From the site:
The Liquid High Hat is a voltage controlled noise module designed by Ryk John Miller Thekreator. It is capable of producing high-hat sounds, but is also usable for other noise generation via control voltage. It is designed to run on 9/12/15V split supply, so should work with most any modular setup. It is comprised of very common parts, so there is no need for hunting down obscure/rare parts.
Hex Inverter Electronics has designed a circuit board for this cool project, to make it available for everyone.
UPDATE: Matrixsynth posted a demo video (not the greatest demo but you’ll get the idea)
These are a great way to add USB to your DIY MIDI device, or to build a USB MIDI interface with up to 5 inputs and outputs. No driver is required under Mac OS X or Linux, and a Windows driver is available.
I had three, but I used one, I destroyed one and I lost one. I now need at least two more.
These chips cost 4.50 EUR each – pretty cheap. But there’s a catch: the minimum order is for 250 pieces. TK over at the MIDIbox forum will probably be willing to set up another bulk order if he can gather enough interest. Right now over 160 pieces are wanted.
Maybe you want some! Builders, why not have a look at the details on the MIDIbox forum, and get some for yourself!
