Tell us about yourself!
I too would like to see the source code. I would like to build a hot plate myself, but have no intention of just copying this. This is inspiration for how I might want to do it, and it's incomplete without the source code.
I am a retired software engineer with over 40 years of programming experience; I do not need any assistance. I just think it is the nature of this site to share, and that includes soure code. I myself have nothing here in instructables, but everything I have on thingiverse or up on github include source code.It's your perogative whether to include yours or not, but I just wanted to state my position.
