heat blanket almost done.
i connected the wires etc. it consume 12 at 230v same as 12A is a quit alot, it gets hot to quick, and ive tried a cheaper silicone White one because i dont nedd to much temp to the top, so he said the white silicone hangs something like 120º and i nedd 90ºC so it could be good, if not ill do a new one with the red one to the top...
my concern it is to avoid a PID controller, to do that i need to cut the power ( voltage) and iamm trying to find the best solution, and i thought about the oil heater (home ones) they have a good potenciometer to regulate the voltage...
any thoughts???
best regards

here we go once again: DON'T TRY TO REGULATE THE VOLTAGE...way too expensive!
the link rich posted is good...they have a couple of dimmers that allow you to regulate the wattage. this is the one i'm using: http://cgi.ebay.co.uk/M028N-LEISTUNGSRE ... 4aa5d96e71
btw, with those homemade blankets it's always a good idea to use a dimmer to make sure they don't go up in flames.
this one works up to 15A, but needs cooling like the kemo: http://www.conrad.de/ce/de/product/1831 ... Detail=005

Imade 2 mats the way described in here: wire kept in place with nails and glass tape, silicone etc.
I did a "dry run" when the wires where ready attached to one glass mat with out any silicone rubber yet. i regulated the current with an output controller and at a certain spot the glue of the glass tape started to burn in an area of 30cm. i think it could have only been the glue, everything else is glass or wire. now i m afraid to set my mould on fire like endre showed us couple of posts ago.
did anyone had this problem too? i can t tell you what electric power there was, as i was on teh fly to extinguish the fire...but it was more power than i will use for heating skis.
anyway,i m flustered as this glue seems to be the weak point in the mats..

This thread has inspired me. And I believe I may have to attempt it. It's funny how when I started researching things a year and a half ago I thought I'd go super cheap. Fabric press with no heat. I've had so much fun figuring out ways to build crap in my garage that I'm actually putting a lot more time and money into this hobby than I thought I would. Now I guess, I'll add some heat blankets to the equation.
You guys have done some good work. Thanks for sharing.

I'm going through about same process same wood/fabric press with no heat at first ...and everything else you said about the same lolWhitePine wrote:This thread has inspired me.

I'm not a electrician and little hesitant to tackle this project. Afraid to burn down my garage. Actually blankets itself shouldn't be difficult to make but PID controller and stuff I'm not sure.
