Interesting. Different to my build - which I ripped a lot from Bob's. My idea was to try and make an easy build with the nice pre-made modules now available (cheaper on ebay).
Bob's (and mine) use a better temp sensor than the thermistor which isn't as sensitive and can be a bit unstable. But the Jaycar version has some nice ideas.
I'll incorporate some of their ideas when I finally getting around to making mine multichannel.
