At last! The printed circuit board that I designed has arrived for my fermentation chamber thermostat. Actually, I received it just over a week ago but haven’t had a chance to document it. I was very happy to see a package from BatchPCB in the mail. Even more so to find it contained a second bonus board (not sure why, but it will be nice to have another one
if when I ruin the first one.)
As expected, I did realize some mistakes that I made (shocking… I know) in the design of the board . I, for some reason, didn’t allow access to the microcontroller chip for reprogramming purposes. So I had to add another header on the board for that. I did this by drilling small holes in the pattern of the header into the PCB. Then after placing the header into the holes, I soldered small stretches of 30 gauge wire between the desired contacts. There’s nothing like going at your new prized possession with some power tools to get the blood flowing!
I also decided that the placement of the LED’s on the board were too high (with respect to the faceplate of the case), I resolved this issue by placing the headers and LED’s onto the back side of the PCB and then installing the board face-down inside the case. This moved the LED’s further down on the faceplate.
So after performing all the necessary changes, I soldered the remainder of the components. I still have to test out all of the connections before I can add power and start
using troubleshooting it, but all the parts are there… and I’m pretty happy about it! Here’s what it looks like:
