TimoRozendal
Hi All,

finally this one is ready for those who want it:

My adaption of WSynth's FM Ogre / 'dspicable'.
It is based on Bill's latest narrow design, but then:
- enlarged to 8hp and made some more space here and there to solder.
- added a pcb for the controls
- changed a few things in the schematic (mainly adding lots caps, using external voltage references, changing the scaling of inputs and getting rid of both -5 and +5v)
- made sure the firmware works with all Bill's and my changes.

it took a few iterations and discussions back and forth with Bill to get this far (including an encounter with fake chips in between), but I am happy with this result.

Here are a few pics:




Here are a few instagram demo vids:

build info/code:
it is SMD and mostly 0603 (with some 0805 and a 1206) an of course some chips. The dspic itself is the hardest, but not that scary if you have done MI stuff.
btw, the chip is a dspic that needs to be programmed with a pickit 3. I will try to do a test this week to get pre-programmed chips. (update: these have arrived, will try to test them soon)

here is the online BOM & build info doc (work in progress)

Design files (Fritzing)
Code

Bill/wsy made a mouser cart (without pots/jacks, still needs to be verified)

listentoaheartbeat
I want three sets of PCBs (including panel PCB, but no panel). Thanks a lot! thumbs up
TimoRozendal

see previous message
the pusherman run might come earlier, since now I need to order a new batch (after enough interest has been expressed)

(btw, for others: pusherman refers to a facebook group buy where this design was part of as well)
wsy
I suppose I should get on the waiting list too? :-)

Cool! That means software development can march forward! I have only one unit right now, because the front
panels are such a pain to make in MU.

I'd also be good with two sets of PCBs instead of three, if that helps.
oberkorn
