Step 4: Building for testing
You can pick up the same case at any home improvement store. I took a Dremel to the front panel to make the cut outs. I'm ashamed to say that I was sober and yet the cuts came out that badly.
So, how do you test this? Having a massive smoker in your house may not be convenient. I used a small Tiffany lamp. Tape your thermocouple above the bulb and maybe throw a cloth over it. This will make debugging the PID loop that much easier.
