AVR Synth, electronics

Came across this fancy little project by Jarek Ziembicki / Elby Designs during this summer and figured it’d make a neat one to test building a rack module. Compared to my earlier projects, I figured I’d also first (for once) gather all the parts before starting assembly. That is, as the project isn’t a big one it’s best off completed within a few sessions.

So today, I completed the electronics assembly. Not much to the board as the part count is quite low, sorting out the matched resistors for the D/A converter was maybe the most time-consuming bit of the electronics bit. I’m even too lazy to snap a photo out of the plain board so I’ll just borrow the one from Elby Designs site ;)

Differences being, my board has the DC regulator heat sink installed horizontal (vertical installation wouldn’t fit inside a 1U rack case) and for the two-pin cables I use Hirose cable crimps/connectors instead of screwdriver terminals. Next up, the mechanical assembly. Looks like there are some clear plexi covers waiting to be binned at work, reckon they could be used for the casing..
