[pcb+panel] Ian Fritz 2x ad/ar envelope for eurorack (4hp)

Post by TimoRozendal » Wed Nov 02, 2016 5:26 am

Hi all, I made 4 hp eurorack adaptation of the Ian Fritz AD/AR. Hereby i present it and I have pcbs and panels on the way (all with Ian's kind permission)

The module is based on this circuit with the following modifications:
It has twice the ad/ar envelope circuit
It is without the delayed pulser part
There is a led indicator to show if an envelope is active
Input of the first envelope is normalled to the second envelope
There is an additional switch that converts a gate into a trigger, combined with the previous modification this can result an a simultaneous AR and AD envelope with one incoming gate signal
Schematic can be found here

Known limitations:
-The envelope won’t retrigger if the attack is still busy
-Some very short triggers are not passed through when the gate to trigger switch is enabled (when switch is down)

Build info:
It is all through hole (with no standing resistors) with standard components, but it is a bit dense.
Here is the online build doc with more info

availability/pricing:
pcb: 7 euro
panel:7 euro
shipping: 3e for a pcb or pcb+panel (other orders need to be calculated)
I have 20 sets on the way (and perhaps a few left from the first test batch, need to count/check)

niicholas pcb+panel [shipped]
GryphonP3 pcb+panel [shipped]
mutedial pcb+panel [shipped]

pcbs/panels are in, everybody who expressed interest should be notified now.
Oh, and darkstar, I only have 1 steiner parker set left and I first need to check with someone who expressed interest in it before. Will get back to you soon.

Received my set yesterday :hyper: Built it up today, and worked right away! Thank you for this addition to my rack. One little thing about the BOM: it lists only one Led, two are needed - almost not worth mentioning.
