The V2164 from Coolaudio seems to be a safe drop in replacement for the SSM2164.
Though to me it is a bit getting used to the idea that in the future there may actually be a Behringer part in the Ben ...

Who is interested in building a Benjolin while we're in Mallorca? I need to know a little bit how much kits and tools to take with me.

You can post here or PM me.

See ya all,

If possible I will be there as well. And if there is interest I'll bring some Benjolin kits for people to build.

Gonna be fun again!

Is this available for purchase in the US? Or second hand?

For those on the waiting list for the STEIM workshop on March 27th, there is another workshop scheduled for Monday May 3rd. Please register through the STEIM website.

This is for those who know and have the means to etch and drill a PCB by themselves. You can use e.g. a 3M CG3300 transparent overhead sheet and a laser printer to make the film. Make sure that the to ...

All stuff is there?
Like soldering stuff etc?
Looking forward!

Yep, all except beers for after the workshop. And a jam afterwards seems unavoidable... Wink

Can i build a Zeigeist to Rob?
And yes i'm in!

Welcome! I'll send you the address later.

Its only the Benjolin this time.

Sunday December 20th, 2009, starting at noon, there will be a Benjolin workshop in The Hague.

Workshop cost is euro 80 including a Benjolin kit plus an extra jack connector board with eight connect ...

Rob,

The one control on the Benjolin that I don't understand is the filter sweep. What does it do? Is it an attenuator for the filter CV in?

I went ahead and ordered the Leonardo Journal (real ...

Thanks Rob! I picked up some of this info in your talk in Baltimore but this give me much more to think about.

So what is the one resister modification to the Filter?

looks like R37?

No, its ...

The three two-pin headers:

These headers are extra CV inputs for oscillator 1 and 2 frequency and the filter cutoff frequency.

Tip: A simple expansion to the Benjolin is to feedback the oscillat ...

Notes on the filter:

The filter is a plain vanilla 2-pole state variable with some added tricks. Two SSM2164 gaincells drive integrating opamps to create the poles. Like in the oscillators care is ...
