This sounds like something very practical to have around. If you care to share the design when completed, I imagine it'd go over quite well among the group.

The system must be simple (as cheap as possible). With a source of heating (resistance) and several computer fans to circulate the air. Arduino must be able to control the temperature (using the resistance and the fan) according to a predefined schedule. A program is for example: 20 ° C to 100 ° C by increments of 20 ° C / h. 5 hours at 100 ° C. 100 ° C at 20 ° C with a decrease of 20 ° C. Ideally develop a graphical interface to vary these parameters at will. ------------------------------------------------------------------------------ Date: Sat, 21 Jun 2014 01:32:37 +0300 Subject: [SS2S-Main] Re: temperature controller with arduino From: florin.mingireanu82@xxxxxxxxx To: sugarshot@xxxxxxxxxxxxx I can help with the temperature controller but I would need more precise specifications: like temperature range, control "band" etc. On Fri, Jun 20, 2014 at 10:16 PM, Vicente Alvero Zambrano <vicente_alvero_14@xxxxxxxxxxx> wrote: Hi, Anyone know how to make a temperature controller with arduino to make a home oven to cure composite? The idea is to monitor several computer fans and thermal resistances. Must be able to follow a cure profile and decreased with increases in temperature curing. Any volunteer?
