The standard electric guitar is polyphonic, but the pickup ultimately sums all the notes down to a single output – which can be limiting as strings can’t be processed individually.
One solution was to create a 2 voice pickup that could split the outputs of the top and bottom 3 strings. Here’s a potential use case : a portable one-man band setup with a 2 voice instrument around the guitar which would allow a guitarist to process their strings individually to play bass register notes and normal guitar notes at the same time. When combined with hybrid picking styles (a la Martin Carthy and Chet Atkins), an octave pedal and some careful chord fingerings, it would be possible to play the simultaneous lead and bass lines.
This could be achieved with a fairly simple setup – two pickups, each amplifying only 3 strings of the guitar. Read more about it on our post at Banana Apparatus

A Phase 90 clone
BA328 based equalizer
Engineer’s thumb Compressor (still needs some troubleshooting)
A patchbay + signal splitter/mixer
breadboarding the envelope follower
Patchbay + effect split/blend

It isn’t easy to find hammond enclosures cheaply in India, so I’m trying to think of an alternative ….maybe a eurorack-ish format with aluminium plates sitting between railings. That way I could add and remove modules as needed.
For now they sit in plastic electrical boxes that can be found in most hardware stores.
This here’s the Katari, or the kit version of the Atari Punk console that I helped put together while at ISRO. It’s based on the Atari Punk Console and aimed at being used for workshops for electronics and noise making. (http://www.jameco.com/Jameco/PressRoom/punk.html?CID=punk). It’s more or less the same design, just housed in little electrical boxes you can find for 20rs or so. We added 2 light detecting resistors to make it a little more interactive and fun, as well as switches to select between the different controls. It’s a gloriously noisy little thing.
A friend got this fun voice looping toy from the souvenir shop at MoMA that lets you record 3 second long clips and play them back. It has a pitch/speed shifting dial, which is fun, but it does lack one or two features that could make it pretty usable. To remedy that, I added an option for line out, and a toggle switch instead of the pushbutton, so that it could play back a given loop infinitely. Here’s a quick test of the same:
After my tinkering about with circuits and noise last semester during the toy lab, I decided to intern with Yashas Shetty, artist-in-residence at Srishti, and periodic hacker/noisemaker along with ISRO (Indian Sonic Research organization, of course; the local (and perhaps only) experimental sound lab). I made a couple of synths, in addition to taking apart printers, mucking around with feedback, and generally annoying the hell out of anyone within earshot with all possible forms of ungodly rackets. Anyway, here’re a couple of the synths i made, most of them based on existing DIY projects.
The first one’s the Auduino, the basic platform of which i used in my toys as well. It’s based on the arduino microcontroller, though i didn’t really alter the schematic or program much here. The casing was meant to look like really retro radios, and maybe partially inspired by Dieter Rams’ work (at least, that was the intention)
This one is the dronelab, which we designed to put into the mughal looking table/box thing below (hence all the wires). I’ve decided to simplify that, so the final form is going to look far less intimidating, be easier to play, in addition to being more durable.
And here’s An Atari Punk Console, housed in a box made from 2mm HIP.
