Assumptions:
- heated (smooth regulation of heating)
- cooling (smooth regulation of cooling)
- digital temperature measuring instrument in furnace box
- lowest possible price ( student budget)
heart of device is a heater situated in block cell ( aerate concrete) cut to right size. As a reflector I used sheet metal, spirals is set in quartz pipes from old heater, pipes were brokes so I got only 4 pieces that’s why bottom has this shape.
In the block is a hole – it’s a cooler hole under the crib line so worm air will not run away that way.
Outside – of course net, I can’t remember where I found that screen but it is perfect
Casing and cover made of metal sheet
Here’s cooler
Electronics very simple, heater start by relay…(sometimes I’m going to change that but it’s a prototype). As a temperature measuring instrument I used broken multimeter. Althought inside looks like a big mess, wires are not tangle, all is secure and tight. Mess effect is because it’s a garbage construction.
Finishing is not very good, I don’t have professional tools for metal. So I must fight with scissors, borer and home made pincers.
There might be some mistakes, cause I don’t have any project from the net.
Device in 100% works fine, as for me. Especially financial assumption is nice, but also it works well.
