temperature regulator

hallo and good day,

a friend Andreas developed a software and hardware platform for the regulation of temperature in alchemy experiments.
this is a digital temperature regulator which not only regulates the temperature but also logs it,

this can be used with any heating source u like as it is a simple temperature controllered relay switch,
the temperature can be set in software, and is ablte to act as a stand alone regulator, no Pc Needed, only to set the temperature,
normally for this kind of hardware and software u pay allot of money, now it can be made for under 40$ if u get the parts from ebay, and some diy skills

i my self am working on a project that is able to do this from lcd display and the controller itself, though no logging in this version. but NO PC needed,
when this is tested and complete i will upload those schematics as well, the production cost of this device would be about 20/30$

the files can be found here http://www.filedropper.com/temp-regulator
kind regards

Seems the link is down, it just redirects me to : http://www.filedropper.com/

Can we find that information anywhere else?

I've also set up a temperature regulator using the STC-1000 temperature controller. I can post more about it and some pictures if people are interested. I was really interested in this and the software though because the STC-1000 doesn't have any of those features.
