Build: This one started life as an FV-1 Octagon board
The pcb's layout didn't suit my enclosure for this build, so I "off-boarded" a lot of components I intended to modify. I also wanted to include a Sound2Light circuit to drive a light plate in the enclosure. Here's a quick demo of the lightplate in action and all the build pics.
Graphics: The Vitruvian Rocker: At some point during this build, I was inspired to use the Vitruvian man. So I photoshopped him into an octagon, as a tribute to the Octagon PCB inside, gave him a Les Paul, a bandana, a few more arms and the classic sign of the horns.
Like in my previous build, I replaced the 'Vi' in favour of 'FV1' in the name's spelling for the FV-1 Spin chip powering this thing.
The effect names are printed in another octagon in an around-the-clock pattern with their respective control info in gold, silver and copper bands to match the control knobs.
It's printed on inkjet waterslide decal paper and coated with 3 coats of poly.
Programming Tools: I found a lot of help, programming tips/tutorials and free dsp patches in Spin forum and this handy List of FV-1 programs curated by u/nonoohnoohno. I also included some PedalPCB's and a few rarer ones I accumulated through years of scouring obscure/ancient forums.
I used the usual SpinCAD designer and SpinASM assembler to make banks and AsProgrammer to read/write the eeprom using one of my previous builds.
Also found Igor's decompiler very useful in converting compiled code for use with SpinASM.
Outcome: This was a really fun build and what I learned sort of left me wanting more, sending me down this rabbit hole, and driving me to immediately start my next FV-1 build. Here is a quick peview.
