Visualist, an analog paintbox

Although I follow this website for a while, this is my first post. For this project I brought together a 3 channel LED light organ with a pal/ntsc video colourprocessor. The bass, mid and high of the sound is controlling the red,green and blue of the video. The image itself is highly reactive to sliders that cut the image to colorful slices. Magic, psychedelic…Art. The project shows a video of the box with effects and a PDF with all the “knowhow” over here:

Give it a try. It’s a nice DJ/VJ instrument.

Handmade Patchable MIDI Sequencer

by Mike Una

I made this simple MIDI sequencer using a HighlyLiquid MIDI CPU.

The sequencer circuit is the old classic “Baby 10” design, but you could save yourself some time and use the Getlofi Sequencer kit.

The nail-and-cliplead design was inspired by the work of Getlofi’s own Alex Deeba, aka Talking Computron.

In this video I’m using the sequencer to drive the MeeBlip digital synth (which I built from a kit), and it’s synched with some drums and basslines from Ableton Live by sending a clock signal to the sequencer via another HighlyLiquid kit, the MD24 MIDI Decoder.

Towards the Beat of a Different Drummer

So I’ve been performing and recording with this setup for a couple of years now.

It’s basically an acoustic drumset which is expanded through the addition of DIY and lo-fi electronics, as well as DIY acoustic and electroacoustic instruments, into an expressive tool for electroacoustic improvisation.

Here is a video of it in action:

Here are the instruments used:

By Hank The Curmudgeon

Greetings And Salutations! First off Merry Christmas, Happy Hanukah, Joyous Kwanzaa, Wacky Festivus and/or anything else you can celebrate. Oh, if I don’t get #4 out by the end of year Happy New Year! May you have a safe and wonderful holiday season. Here’s hoping you get that soldering station or capacitor assortment you’ve been dreaming about. Now onto this episodes insanity…

#11 Math.

Your generic ubiquitous Switchcraft #11 1/4″ Open Frame Mono Jack…shopped around on 11/26/10.

But Hank, you whine, why didn’t you note the prices on eBay? Because the jacks may, or may not, be available, shipping can be outrageous, I don’t want to wait 2+ weeks for Taiwanese post, I’ve seen the plating flaking off due to corrosion, etc. That’s why I didn’t list eBay…but I’m not ruling eBay totally out.
If ANYONE knows of better prices for Switchcraft #11’s PLEASE contact me! *We have some Plastic Stereo jacks in GetLoFi.com/shop

Urban Planning Meets A Music Sequencer?
Thanks to Chicago Buck for finding this. http://isleoftune.com/ There is some very interesting potential for teaching musical theory and composition to someone who has no music background or training.

Can One Really Bend “Star Wars”?
Or at least use it as a sample source? Yes!!! http://amzn.to/geZjRV If anyone follows through with this I WANT TO KNOW ABOUT IT!

Virtual Breadboard.
Sadly NOT a dynamic circuit simulator but still a neat idea. Plus it’s great if you need a graphic illustration in your handouts for a class! http://musicfromouterspace.com/ElectronicTools/virtualbreadboard/index.html

Extra Credit: What circuit do I have loaded in this example?

$1.2M Accordioning Brass Musical Watch. Even if I had $1.2 M to waste I’m not so sure a watch, this or any watch, would be on the shopping list… http://www.boingboing.net/2010/11/25/12m-accordioning-bra.html

Performance: Catherine Brisset On The Cristal Baschet And Gilles Dalbis On Percussion. What? You don’t own a Cristal Baschet!

Jumbo Otamatone: DIY Seed? First watch the video:

Now, ignoring the silly giant musical note form factor, this would be an easy DIY project coupling either a DIY ribbon controller or a COTS ribbon potentiometer such as http://www.trossenrobotics.com/store/p/5832-SoftPot-Linear-Potentiometer-500mm.aspx with almost any VCO or APC circuit. Now the question becomes what goofy package can you house this in to make a bunch of money.

After You’re Done With That Holiday Brew…

Ax-Man is a DIY Circuit Bender’s Friend

Minneapolis, MN is a very accommodating city for electronic musicians and DIY enthusiasts. Not only is there a sprawling Experimental Electronic Music scene here, but it is also a home to the shopping mecca known as Ax-Man Surplus.

The eclectic main store of this Twin City chain is located on the University Ave in St. Paul and always has something for everyone. Creepy stage props, neon bright duct tape, military surplus, heavy duty switches, arcade buttons, jacks, cables, capacitors, resistors, screws, rotary telephones, speakers, zip ties, tools, shipping supplies, and even an Iron Lung are some of the items. All at reasonably low prices and in great selection.

However the main point I would like to make is this recent Vita.MN article on the Ax-Man stores. A very interesting piece that goes into the details of the store’s history and philosophy. It also explains the funny signs and who the creepy axed man really is. Good Read.
