heatsink

Mounted a few components in the case of ArduinoBox Serial# 2, including the heatsink for the solid-state relay. Should do the trick. This picture also shows the populated circuit board, which only had one small problem in that the terminal blocks on one side are too close to a set of female headers, so I had to replace the terminal blocks with female headers and turn the terminal blocks into a connector. Seems like it will work.

my first circuit board

Just received my circuit board design back from BatchPCB; it only took a couple weeks and looks pretty good to me. For some reason they sent six although I ordered three. I have most of the parts to finish it, thanks to a steady stream of small packages from China recently. eBay rules for cheap electronic parts.

For everyone other than Arron, this is to interface an Arduino microcontroller with the other circuitry and sensors for a temperature controller. It will control a water bath for cooking and eventually the coffee roaster too. And maybe a smoker…

As some background information, here is an image of the various layers that went into the board:
