But this way LEDs intensity is dependant on overral Intensity settings, right?
Wiring it my way gives excellent response, right intensity (that can bi modified according to LED used) and does not depend on bulb intensity settings.

Re: [Replica Files] Shin-ei/Univox Uni-Vibe
Sorry for blasphemy, but what's the best way to add LED rate indicator? I've seen that madbean was taking voltage from R44 to ground. Some folks suggest to pul LED in series with bulb. Don't think it's a good idea. I'm planning to use CANCEL as bypass, so it'd be good if both work together properly...

Did u guys manage to trace bulb driver circuitry? Probably PWM driving transistor?

Re: Jack DeVille Deuce Coupe [traced]
Ah yea, forgot to change the naming when cleaning it up. I think the diodes are a screw up from copying my hand notes, but I threw them away after redrawing so I dunno if I got them right initially or not. Thanks for the corrections. :thumbsup New schem is attached. So are cathodes or anodes connec...

Re: Jack DeVille Deuce Coupe [traced]
What about mosfet body diode? This kind of configuration starts clipping signal above 0.4V. I suppose it could go with this particular circuit (as this is a clipping circuit) but if it's a part of Deville clickless system, i don't thing it would be a wise thing to use mosfet as a switch...

Re: Catalinbread Echorec - Pic and schematic
Not familiar with fv-1 code but isn't it protected? Programs are loaded to the FV-1 via an external Eeprom, so to develop your own effects all you need is the datasheet and language from the Spin site. There is lots of info there to learn the coding. As for the code in the echorec I have no intenti...

Re: Cusack Tap A Delay Gutshots
I have some basic setup on my protoboard. Will try in the afternoon if this "holds the water"!!
If I get some results will let you know guys!!

Re: Cusack Tap A Delay Gutshots
Easy in theory, but nobody has figured it out enough to copy as far as I know. Nice to know it's worthy of dissection... Jon Cusack :idea: Ok, I think I have it figured out. You use a PWM output pin on the PIC with a schottky (two in parallel actually) cathode connected to it via a 4k7 resistor. Th...
