To bad they are not 16 pin! I could have sanded them down and sold them as SAD1024 on ebay.

What I'm I suppose to do with all those PIC 16F684 now!?



?? ;)

I think we need to see a picture of you wearing these, Tom!   ;D

Built this fine pedal today!! Version.3 ic. Subbed volume pot for the Switch mod for different wave forms, cool! Grounding pin 6 helped a lot with the different wave forms. Nice!

Finally it is done (PCB ordered in 2012).

Many thanks to ElectricDruid and Taylor for the help during the build, I had a lot of questions.

Mods:
- TAPLFO3 with Waveset and Smooth switched
- Center detent pot for the Offset knob (it's easy and I find it very useful)
- 4 inputs for the pots (except Waveform)
- Rotary switches for the Waveform and Multiplier
- PWM out, Clock out, Tap tempo in

CRAP where can I purchase an NSL-32   ???

 http://www.smallbearelec.com/Detail.bok?no=356  Small Bear Electronics is your best fiend ;)

There is my build


 For waveform and multiplier i using rotary switches instead of pots. That makes these functions a bit more understandabe. If someone interested - i found perfect rotary switches for that

http://eu.mouser.com/ProductDetail/ALPS/SRBV160803/?qs=sGAEpiMZZMvNbjZ2WlReYusHPuglWmCRYaNeyNyivdg%3d 6 position for multiplier

http://eu.mouser.com/ProductDetail/ALPS/SRBV181004/?qs=sGAEpiMZZMvNbjZ2WlReYusHPuglWmCRbZTSllc6Pt4%3d 8 position for waveform

All you need to do is build additional PCB
There is PCB's (open with Sprint Layot)

with trough hole resistors
NOT VERIFIED because i build second one version with SMD (8060 size) resistors

with SMD (8060)resistors

 VERIFIED

all PCB's is ready to trasfer
Cool build! BTW, I'm curious, how the illumination like this is done?

• PCB from Delek/Cherry Pie: https://www.delykpcb.com/product/cherry-pie-tremolo-pcb
• TAPLFO 3C, LFO Out and Sync In from Electric Druid: https://electricdruid.net/datasheets/TAPLFO3Datasheet.pdf
• 1P8T mini rotary switch (from alibaba, smallbear, adafruit, etc) with resistor string, for both Multiplier and Waveform/Shape, via Electric Druid
• True bypass relay from TH Custom: https://diy.thcustom.com/shop/uber-switch-relay-true-bypass-with-mute-kit/
• Homemade optocouplers using tayda photocells and superbrite yellow leds
• No ticking after removing C14 / added extra filter caps on voltage regulator outputs.

Still learning how all the controls interact together.

Nice build!

Just curious what kind of filter caps have you used for voltage regulator outputs?

Just used regular electrolytic caps, 100uf or so, across both 5v regulator outputs.  Can never have enough power supply filter caps...
