Arduino curing chamber controller progress

We got some good work done on the Arduino curing chamber controller last night.

Initially we had built it with 4 individual relays, but had accidentally snapped a leg off one of them, rendering it useless, so we replaced the individual relays with a great new board. It has 4x240V relays built onto the board itself, check it out:

You can see that it has LEDs on to indicate which of the 4 relays are active, but we wanted it to control the front panel LEDs instead, so we de-soldered them from the board, soldered some new pins onto it, and then wired them up:

Starting the mains wiring. It’s so much neater in the case now we don’t have all the individual relays wired up.

Here it is all wired up to the mains, and running a test program which cycles through all the relays in turn – I’m pretty damn excited now!

The remaining tasklist is as follows:

  1. Fix the front panel and the lid on the enclosure (the lid is already laser cut)
  2. Write the software (!)
  3. Make some epic cured meats
  4. Profit?

 

I’m planning on running this in tandem with my other curing chamber controller, at least initially, just to see how it behaves, and to fine tune the software before using it in anger.

I’d also like to eventually add data logging for temperature and humidity, so that I can graph it via something like plot.ly and this arduino library, but that can come at a later date.

  1. Awesome, I totally want to build one. You should open source everything and sell the parts or finished product for those who are not tech savvy.
