Alright let’s review what we are working on here because it’s been a couple of months. When I last looked at this a few months ago, I had just put together the new design of my #8bit #vcdo with my diy #EZMakeOven (a reflow oven for SMT soldering)

And because I cannibalized my test harness for another project, I hooked the new VCDO directly up to my #ArturiaKeystep

And it was acting really really weird. I could not figure it out. I inspected the board, but nothing made sense.

When it was light outside earlier today, before we went to the store, I soldered the MCP9600 (thermocouple amplifier, for the #EZMakeOven) and an MCP4725 (for another project).

You can see my secret to soldering these headers: a breadboard to put them in, and a stack of paper under the board itself. If you don’t have the stack it tilts down kittywampus.

Today I fought with software for the #PyPortal. (The pyportal is the brains behind the reflow oven that I’m in the middle of making)

The #EZMakeOven page says use the latest version of circuit python. When I wiped the board and installed the latest 8.x, then installed the EZ Make oven software package, it was missing some libraries that it needed.

I eventually found an #adafruit circuit python GitHub repo, and installed that. Now, it finally works… er, well it doesn’t

Yesterday in #EZMakeOven news, I got the headers soldered on to the temperature sensor breakout board.

Stencil and Kapton tape arrive Friday!
