[foodhackingbase] experimental incubator test - how to make h-bridge from darlington arryas

[Frantisek Algoldor Apfelbeck]

Hi to all,
I've finally fit my heating and cooling unit into the proper insulated 
box, no pictures so far probably because of the shame related to my 
"handy work" - I used at the end wooden plank, cut the hole in the 
middle, fit in the heat sinks, screw it up and applied the silicone 
around it, tomorrow when dry I plan to do the "final polishing" and 
drill a whole for a temperature probe + power for the inner ventilator. 
Also tomorrow I plan to finish it up rewiring the bread board (got few 
cables disconnected from the set up) and I will run a test. My hope is 
to be able to heat to 45C and cool to 15C. I do not have a H-bridge but 
I have been told that the darlingtion arrays which I have can be used to 
make one which would be suitable for this use, any ideas?

Anyway talk to you more tomorrow I hope to share some pictures and info 
on a blog or foodhacking base wiki page and forum.

Talk to you soon,

Sincerely,

FAA
