Custom build for my friend Jenny who plays as Gossimer. I’ll try to dig up some video because this thing sounds kind of demonic. It’s two cassette decks hacked together with a single loop running between them. You can record continuously onto the tape or simply play it back. You can also control the speed and direction of the motor with a wimpy little 555 PWM circuit I threw together (heat sink bobby pin). LM386 amps pick up radio signals REALLY well, so I spend a substantial amount of time thwarting those signals with various components strategically placed on different pins.
I received a commission to circuit bend a number of different things, including the Casio PT-80 shown.This particular Casio is less sought after for circuit bending as not many tone bending or glitch points can be found in it as the sound parameters are stored on a memory card. There are, however, a number of interesting percussion effects available with some exploration. I added three switches which each effect the percussion in a different way, plus a pot to allow a sort of filter sweep, as well as a pot to rapidly alter the tempo. A fun circuit to bend, despite its limitations.
This past semester I designed and constructed an instrument that modulates sine waves with the amplified sound of light bulb filaments. The instrument is in two parts: the first being the amplified light bulb interface which allows for control of amplitude and the frequency at which the filaments are vibrating (by way of dimmer switches), the second being an FM synthesis interface (originally conceived for two teensy 3.1 microcontrollers programmed to generate a series of four controllable inputs, sine waves, and outputs– this proved a problematic and unstable system as one of my audio shields intermittently failed) in Max MSP mapped to a MIDI controller. The sound of the light bulbs are routed individually to control four respective sine waves in Max. The MIDI controller allows for immediate control of the overall amplitude of the sine waves, individual amplitude of the sine waves, modulation depth (how much the sound of the filaments effect the sine waves), and base pitch of the sine waves (which are harmonically related, each offset an octave from the base pitch).
Hey team! Here’s a nice little recording of a performance I did in class a couple weeks ago. I used a little two grain synthesizer I build with arduino that is SUPER simple, and if you want one, you can build one too, the project is called Auduino. I changed the code a little bit just to change the pitch mapping a little. I also used my Elenco Electronics Playground, and built a little light controlled oscillator and flashed a light through prisms and crystals to control the CDS cell. I also used a Casio VL-Tone with a nearly dead battery, and a dynamic microphone. All of this was routed through a little mixer into my audio interface into my computer, where it was processed through the live granular sampler I have been working on in SuperCollider. I recorded most of this, and there is an explanation and some questions at the end:
