Think you can strip?

This fellow must have an unprecedented amount of time on his hands!

Astounding!

he does what I used to do with strip.. cut 3 traces in the corner, drill a hole and push a bolt in there
I never made anything big enough to eat your dinner off though!

from the site:
"I'm sure that many people have built designs such as this before and been a bit disappointed when they set up the faders or pots to give a violin or clarinet waveform (out of an old text book) and found that it sounded nothing like it. It just goes to show that real instruments and interesting synth sounds have complex dynamic waveforms with constantly changing spectra. What I've made here is a time domain tonewheel organ - without the tonewheels. You draw a waveform rather than altering harmonic drawbars."
Very true, and very sad.
And, if anyone is up for an interpolating scanner, go over to Don's house:

Eh?

ahahaha, no really, what?

Anyway, he could have learned to play a clarinet.. AND the violin in the amount of time it must have taken to strip all that up ha!  that actually makes it quite funny in my book

" The pictures are a bit fuzzy because of the exposure time and I wobble."

I can relate to that...

That analog linear interpolator is a great add on for a sequencer.

[Paul Perry (Frostwave)]

Actually, I think he probably did the whole project in less time than it would have taken to lay out a PCB.
Surface mount caps are particularly suited to stripboard, you can either jump them between traces or across holes!

 Pretty interesting approach to waveshaping!

I wouldnt expect it to sound like 'real' instruments at all, but I bet it can get pretty inyteresting electronic sounds...

And, who the hell wants to build a tonewheel organ?

Well, some of my friends won't go in a room where there is a guitar, so it takes all kinds.... there is also the point that, if you DO like tonewheel sounds, then making them with something weighing less than 300Kg might be desirable. In fact, since a traditional tonewheel has locked ratios, it might be superior to make a polyphonic tonewheel emulator - but that is a long way from stompboxes I guess. Anyway, I think ANY kind of DIY is a good thing, don't forget that amateur robotics is what keeps some of the smaller suppliers open so that us stompboxers can benefit too.

[Meanderthal]

 Oh... hell yeah I like tonewheel sounds... I meant actually mechanically building a tonewheel organ(with 800 pound of gears and motors and cogs and sprockets ). I wonder what the 200 ton steam engine driven Telharmonium with its human sized tonewheels sounded like...

This is at least... thinkable... although I doubt it sounds anything like a Hammond, I have no doubt it could sound cool in ways all its own!

That's some fairly serious perfboarding there. 

[Rectangular]

I've noticed guys that seem to really know their stuff just to straight to perfboard.  the majority of Juergen Haible's stuff is on perf,  regardless of how absurdly complex it is. I guess it comes with a lot of confidence, to just throw all the components onto the board directly, instead of fiddling with PCB CAD for a week, for fear of making a mistake.

btw, I really want one of these waveform generators, this thing looks fantastic

It LOOKS fantastic, but these 'arbitrary waveform generators' are always a disappointment to me, soundwise.
Where they ARE good, is using them at a low frequecy for a more complex LFO. (hence the success of the Zvex boxes with the 8 pot sequencers).

[Rectangular]

actually thats where I was thinking of using it,  this thing would make a great LFO CV controller,  you could get just about any pattern possible. I wonder how much it would have to be modified to function strictly as a CV generator
