The main idea is to made a home oven from plywood and foam insulation. I 
planned dimensions of 2 x0.5 x 0.5 m (Free). With these dimensions we can cure 
any parts necessary for SS2S project. Recall that the largest piece so far is 
the nosecone (1507 mm). For smaller piece, and in order not to waste energy, I 
have thought the manufacture of a partition. 
You're right about the fans. I'm sure I can get some free fan oven, as well as 
The objective of using arduino, is the possibility of developing a graphical 
interface in which to determine the temperature rangesSubject: [SS2S-Main] Re:

As much fun as it is to play with Arduinos it's a waste of time & 
money.Programmable PID Temperature Controller with single or dual sensors can 
be purchased on eBay for $15-$60. 
Where will you be placing the temperature sensor for the controller, embedded 
in the part or on the surface? Or are you going to try to run the oven at the 
desired temperature and guesstimate the time it takes for the part to 
equilibrate? I believe that would problematic and take longer to achieve your 
cure. I think that the manufacture of the composite materials should be able & 
more than willing to provide you with general propose curing methods & 
Are you building your own over with strip heaters, fans, etc? Or are you 
planing to interface the controller and fans to an existing oven?
For convection circulation you only need constant speed fans and if you plan on 
using axial flow computer type fans be aware most are rated to 60-C or  70-C.  
You can get 105-C rated fans but not from an old computer. sofasco.com is one 
of many places you can get them. You could use standard fans but it anyone's 
guess on how long they'll last.If the parts are small you can buy small 
electric convection ovens sold as Toster/Pizza ovens.Check Walmart, Best Buy, 
Target, eBay, Amazon.

Florin that's perfect. 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.

I can help with the temperature controller but I would need more precise 
specifications: like temperature range, control "band" etc.

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?
