Subject description: CHECK PM's
Reply with quote  Mark this post and the followings unread

i decided to offer an eurorack front panel with the same look as the 555-VCO, and can re-order more PCBs if needed. cut-off date 19 JAN 2013

LFO with lots of functions:
Thomas Henry TCL555 based LFO Controller (e-m.com)

i am taking orders until 5 NOV 2012.
just contact me via this thread or PM or email, telling me how many PCBs of each (circuit=CB, frontpanel=FP) you would want. be honest about your interest, please.
i won't take any money before i hold the PCBs in my hand. as soon as the PCBs arrived from manufacturer i will contact all who indicated interest concerning payment. paypal preferred.

now to the numbers.
each PCB (circuit or frontpanel) = 10.-USD/7.50 EUR
eurorack front panel = 13.-USD/10.-EUR
shipping outside europe:
1 PCB = 3.-USD, 2+ PCBs = 6.-USD
shipping europe:
1 PCB = 2.-EUR, 2+ PCBs = 4.-USD
shipping deutschland:
1 PCB = 1.-EUR, 2+ PCBs = 2.-EUR

what does it do? refer to thomas description in the link above, here is a quote:
Quote:
In triggered mode, as long as keyboard triggers are appearing, the LFO is quiescent. When the triggers eventually stop, the output signal smoothly ramps up to full amplitude but only after a desired interval. This creates the so-called delayed vibrato effect when used to frequency modulate a VCO (voltage controlled oscillator).
In gated mode the LFO is quiescent as long as no keyboard gates are present. But when a gate is finally detected, again the output ramps up.
Footswitch mode is similar, but now it is an ordinary short-to-ground footswitch which enables or disables the LFO.
Finally, with neither a keyboard trigger nor gate present, the unit behaves as a standard freerunning LFO.
All in all, with these basic modes, in addition to a variety of panel knobs, switches and jacks there is hardly a synthesizer control task that can’t be accommodated. Experimentation will probably uncover other valuable uses.


I have the permission from Thomas to do a PCB run for this project. i will offer the actual Controller LFO Circuit PCB, providing MTA-100 headers for easy wiring-up any format.
Additionally i will offer a frontpanel component PCB, which can be mounted piggyback to the circuit PCB. It provides footprints for 9mm vertical mounted potentiometers and vertical mounted sockets (available from earthenvar, however, there are kobiconn fitting the same footprint!?).

i will not provide any building documentations, just refer to the original documentation available from the link above. thomas documentations are very comprehensible, and the PCB lables follow thomas schematics.

here a sketch of the professional manufactured eurorack front panel:

here is a very short demo of the Controller LFO. NOTE that i mixed up the labels of the mode switch: Trigger should read Gate, and gate should read Trigger.

I don' actually need any more LFO's at the moment, but I may as well grab two basic circuit boards to add Tom my Fonik PCB collection.

Regards

Fonik,

What kind of pots did you use on your prototype?

Thanks,

Dan
