The heat sensor is from the hair straightener i took apart and i believe it just tells the controller to not fry itself. It was attached to the old heating plates so onto the new ones it went. This is all just testing for when i do get the heaters in. The ones ill be making will be analog hopefuly.

damn GF looking good! i want one!
SF and i were discussing rewiring the hair iron circuitry to some ebay PTC's a month or two ago, but i need to consult with an electrical engineer or something for that kinda work or i might burn the house down.
hope it works perfectly!

Be careful using those hair iron controls. I don't believe they have a heat sensor or thermostat of any kind. The PTC's are a fixed temperature and the controller simply kicks it up or down. It is not thermostatically controlled. It's all calculated, not sensor based.
If people start comparing what the hair irons say vs what they measure with a real thermometer is probably going to be very different. Especially model to model and mfgr to mfgr.

They actually have a sensor. Pretty sure all hair straighteners have to. If they didn't the heater wouldn't know when to shut itself off.
I've had my buddy who is electrically savvy take a look at the control boards I've had and each one has had a sensor. There is also a mosfet on all the boards I've looked at which is what is controlling the heaters.
As I understand it the Mosfet is controlling voltage/amperage like you said and the sensor is just there to keep the heaters from reaching a certain temperature.
LOL... You answered you own question. A mosfet is a dimmer switch (in this case). It controls voltage and amperage from source to drain.
Probably one of the most common transistors.
Hey Ringo
I'd love to see pics of your plates when you get a chance. I've been looking at A-frame presses. I've got plenty of harbor freight stuff in my garage. Some works great, some not so good. From what I've read the assembly of the HF A-frame is a little tough cause the instructions suck wang...though I've seen there are some youtube vids that might help

I could be very wrong about what I believe to be a sensor of sorts. On one of my old irons i was using, one of the heaters had a fuse mounted to it. The info on it is
SEFUSE
SF240f
JET240 degree C
CCC~250v
C14Y2
Could be a fail safe of sorts? The one I have on my current controller was also mounted to the heating plate but it is much smaller and am unsure if it is the same type of piece.

I'll post some pics later today. As for assembling the A-Frame press, I also read the horror stories about assembly but mine went together...1, 2, 3. And, I am not very good with my hands.

I just tried to make some of this for the first time but i'm not getting anything?
I have the hair straightener set at 220c and i press down hard on the flowers inside the paper for about 3 seconds and hear a slight sizzling sound, but there is no oil?
What am i doing wrong?

If you arent using a clamp to increase pressure you may have to press longer or increase the heat. Give a 10 second press a try at 220 and see if that helps at all.
As for the hair straightener controls i do agree that you shouldn't go by what the read out is and instead do a temp reading to get the proper results, then you can make a simple table to reference. I will be going with the rotary dimmers as they will be easy to work with and setting up a reference chart will be cake.
220 Celsius? that might be a problem. 220c =428f
Didnt notice the celsius : P thought he meant ferenheit. Good catch!

So 220c is basically combusting the oils? No wonder i feel a bit high.
What is the optimum temperature? I have seen different opinions......

Ok, i just tried it at 120c/ 248f which is the lowest setting and it worked.
Thanks.

248 is pretty sweet. I do it just about there, leave it on for maybe 30 seconds, then turn it off, and let it sit for a minute or more, it gets a really thorough uncooked extract that way. if you have moister buds its way better for yield too.
