Monster Box, Creature

I have started a new direction, a Goblin box.  Dimensionally  it is smaller than previous versions yet it still will yield incredible sounds.   Here is the start, some basic parts from my supplier.

The circuit is designed, but I am still working out the details of the graphics for this unit.  More to follow.

April 3

Circuit is just about complete, just a few more wires to solder (output, CV, and power jacks).  Painting is now finished, see below, I'll let the paint fully cure and harden before assembly.

 

April 5

Soldering of the potentiometers, jacks and switches is now complete.  A trial run last night confirmed that the circuit is working and is operating as planned.  Time to close it all up and install the knobs. 

 

April 6

Assembly is complete and all systems GO!

 More details and video to follow.

Demo hosted on YouTube.

This circuit is based on a square wave oscillator, two of them actually; one astable oscillator driving a monostable oscillator.  Both signals are combined together in the circuit and a single square wave frequency is the output.  This build hosts frequency, rate and an added choke control on each oscillator.  There is a CV input on the monostable side and I included two feedback switches.  One of these switches sends the astable signal through a different route to join the output signal.  In addition, there is a input power jack for 7 to 9 VDC 2.1mm input and a 1/4" mono audio output jack.  As the finally, I created the creature which sits proudly atop the cast enclosure in a faded white to gray/black background.

Just adding an additional picture of the design.

Atari Punk Console, Hello Kitty

Atari  Punk Console (APC) housed in a Hello Kitty candy tin.

 

 

Inky APC

I couldn't resist, I made another version of the Atari Punk Console with a Inky candy tin.  This one has an added body contact on the back of the tin to adjust/interfere with the signal from one of the frequency potentiometers.

This one will be up on eBay like the others.

Circuit bent Yamaha PSR-6

I recently completed bending a Yamaha PSR-6 Synth/keyboard.

See: Circuit Bent Keyboards for more details.

This modification included a data line patch, pitch distortion and body contact with a sensitivity control.  The keyboard is fully functional and operates as Yamaha intended :).  However, I thinks it's better distorted and mixed up.
