VERY nice - actually very curious about the economics of boards like this, is it even vaguely worthwhile designing something small to be built if it’s not also manufactured for selling on etc - i.e. are bespoke boards like this not financially viable for the one-off hobbyist, in terms of how finished it looks - obviously shoving a proto board in a box is plan B - but that looks very sweet
anyway - the reason to bump that was wrt those breakout holes
I’m trying to get a different set of cables for the VM - there are two reasons, one, the ones I have (not the Korg ones but quite close gauge-wise afaict) are prone to bending and disappearing in the edge of the receptor because of two - my elderly eyes are NOT what they were a year ago - I seriously struggle to see the holes and because the Korg labelling is mostly not lined up - it is a total PITA lining them up - this aspect more than any other is the headache that could derail this west coast honeymoon
now I’d ideally like to make my own, but I saw these from Tangible waves (pinging @thetechnobear for opinions too 
) , a bit pricey to get a whole lot for this device, and the question of wire/pin gauge arises, and thus why your photo is useful
if pins were used exclusively within the VM or AE_Mod would either suffer contact issues if dropping back to the thin jumper types
The reason this is now important to me is that I think the extra metal shining will make it easier for me to discern the jumper tip - to solve the visibility issue I’m going to do the following (a bit like some visibility ‘mods’ I’ve done before …
by maybe wrapping a piece of labelling tape over the top edge from under the faceplate and pre-piercing or punching holes in - I genuinely struggle otherwise - even with inconvenient head torch and reading glasses - it’s just too fiddly otherwise - not enough contrast - I don’t want to paint the frame at the top of the mating blocks - way too fiddly, so a temporary solution will do for now
a bit like this perhaps ?! …
more form with this stuff, it’s not pimp my synth, I genuinely struggle to ‘read’ it otherwise - some additional thin white layers above the black switch covers on all the Pro-1 slider switches - will tone those down to grey one day - but much more usable than black
all these images are showing clear gadgets under bright lights, but that’s not always the operating environment - especially for the Korg VM
Anyway - any tips on the gauge spring ‘retention’ issues, or procuring these pins (name to google) - or cables or solid core wire gauge which I can heat shrink some grips onto
I tried a smoothed off cut paperclip for a pin and it was just about the limit, I could solder these into female/female pins with a wire of my choosing and heatshrink it - but don’t want to ruin the connection over time etc
PS - just about to put an order into CPC - so if there are any passive components I might like to throw on a breadboard to extend the VM functionality then please throw ideas out beyond switches/pots/resistors/caps/piezo etc - especially interested in any low voltage ic chips which could be serviced somehow to offer simple logic clock dividing or whatever - even if additional power is reqd. I’ll do something on Arduino eventually, just looking for some fun that perhaps can get my son tinkering beyond micro-bit and maybe we’ll make steps on the r-pi front as a result
any tips welcomed
