'Lil Boxes Part 04

Here's a real treat, a trio of handmade marvels put together for us by our mate (and component/solder and all round audio genius) Andy Lemon. As well as making these little beauties together for us we also persuaded him to scribble down a few words about each , so over to you Andy...

Tupperware Party Synth
"This ones my own oddball combination of a few different experiments generating audio via monostable osc's using feedback, osc drain and stable oscillation to generate more interesting tones out of a very simple circuit. nice thing about this design is you could chain lots of these together to make monstrous drones :) plus it's insanely cheap to build! I've popped the guts of this one into a tupperware box bought in a multipack in poundland - who needs project boxes when you can get 3 for a pound."

Highly Flammable Filter
"This is loosely based on a Forrest M Mimms circuit from his lovely book "Op Amps IC Circuits" - the filter itself is a 'sallen key' lowpass filter. It has a lovely warm analog sound to it, with proper cutoff and resonance control based as it is off the 741 amp. the design allows you to plug in any sound source and give it a little filtering joy - instant grit and fatness. It's built into a ex rental video cassette case I had laying around for one of the old tapes that got eaten by my trusty VCR (great for building these things in). I'm currently working on a filter +overdrive combo unit based on this same design soon with clipping control..."

Punktastic Synth
"the punktastic synth is a bit of a hacky job of Forrest M Mims 'stepped tone generator' circuit ( which got renamed to the Atari Punk Console on the Internet as these things do).
My mods are really simple and involve just messing with the default capacitor types and values to produce a more interesting and warm sound. I used very high value pots to give to give a little more control to the user when making the beep beeps and trying to eliminate the total randomness of the sound generation. I built it into a little mint tin I had laying around - you have o remember to shield the innards of any metal box you use or otherwise you'll have all sorts of wonderful electronic grounding issues..."

Are we chuffed, oh yeah.......;)
