Convulsion Generator REDESIGN (skiff friendly, acrylics)

Post by futuresoundsystems » Mon May 06, 2013 5:06 am

A slight physical redesign of the Convulsion Generator FIL1 is now available with acrylic panels:

Image

This new design ensures skiff-friendliness (the depth behind the front panel is kept within 27mm), and, with the acrylic front panel, a slightly cheaper price of £50 (as opposed to the £60 aluminium version).

Note that the acrylic panels are currently 3mm in thickness - 1mm more than standard aluminium Eurorack panels. I'm trying to get some batches made up in 2mm, but I'm slightly concerned they may be too flexible. We'll see. For the time being, the 3mm acrylic is nice and sturdy.

For those alu-lovers, this redesign WILL be available with an alu front panel, as well as a few additions to the circuitry, mainly in terms of normalling.

For more photos, see the FSS Facebook page.

Cheers!

new design looking nice and skinny..
The circuitry changes you refer to are they significant,and are they implemented on this new acrylic version or only on the forthccoming aluminium.

They aren't at all significant really. They're going to be introduced with the next run of PCBs, so hopefully quite soon. All they will introduce is a set of jumpers on the PCB to choose how you want to normal the Input connection.

The "classic" FIL1 has its Input floating, which causes the output to stay negative with no input.

This latest PCB for the next few acrylic builds has its Input normalled to ground, so the output is at 0V with no input.

The next PCB will have jumpers to allow the user whether to normal the Input to floating, 0V or the + Output (this causes the FIL1 to turn into a "chaotic" oscillator, but only at certain settings).

For sure! Was looking at the board earlier today and it really shouldn't be difficult at all :guinness:

Have the new set with the jumpers been made? The chaotic oscillator function really interests me so I'd like to hold out for that.

They have, but funnily enough it's very difficult to get it to oscillate without an external stimulus, so you're better off mixing one of the outputs back in with the input stimulus.

Sorry just to clarify, would the older revision oscillate by patching it as well or you need the new version with the jumper in addition to patching it? :hmm:

Either will oscillate with external patching (+ mixing if you want extra input excitation stuff) :)

ok thanks for clarifying.

This one is definitely on my radar and I'll be picking one up soon! :guinness:

Based on my previous post to this thread I wasn't that quick.

What was quick however was your ship time, made it here yesterday after I ordered it last week! :sb:

Heya, FSS,

I see you make this available in Frac format, and I'd love to add it to my BugBrand. Would it be possible to acquire a banana version with MTA100 connectors for power? Thanks!
