Hey everyone! I am trying to change the min temp from 275F to 150F. I have added a dimmer switch to an extension cord but all that did was double how long it took to get hot.
Is there anything l can do?
Fyi: not much exp with electronics so layman's terms would be preferred if possible
You are picturing working along the line of "it emits a certain amount of wattage and that reaches a certain temperature before it can't add heat faster than it cools down."
In actuality, it has more than enough wattage to get very hot, and has an internal mechanism that just shuts it off once it gets to the target temperature, and starts it up again if it gets too cold.
The temperature is usually either regulated by some kind of thermistor (solid state) or by a bimetallic strip/wire (electro-mechanical).
If it's the thermistor, then you need to understand how the temperature regulation circuit works and modify the components appropriately to change the thresholds.
If it's the bimetallic strip, the way it works is the strip flexes as it heats up. Eventually it touches a probe and closes the circuit, signalling that it's overheated. You can adjust the position of the probe to change how far it heats up before contacting the probe.
If it's a wire, kinda the same principle. The wire heats up and expands, and after expanding far enough it (or something attached to it like a lever) contacts the probe and closes the circuit.
I think hair dryers will typically use the electro-mechanical options, since they have more space to fit that kind of thing inside the body. The straightening iron seems pretty compact, so it might solid-state.
Actually, I think I'm just too old. I took a closer look at my cheap hair dryer that I thought was a wire-probe, and it turns out it's a thermistor on the wire. So everything is probably solid-state these days.
Whoa! Thanks for the info! I am guessing l need help for this one lol
actual helpful and knowledgeable PrepHole advice.
I didn't realize reading a popular mechanics article about how thermostats and toasters worked I found in my grandfather's basement 30 years ago would help me teach anon how to make cannabis oil, but life has carried us all here to this moment.
i glad we could meet here anon.
see you in another life brother.
I thank your grandpa for buying that book and past you for reading it!
The dimmer switch will reduce how much power is delivered to the device, not how hot it allows itself to get. Think of ratings on a stove, 1000BTU will heat slower than 2000BTU but both will get to roughly the same maximum temp, not half/double. Another way to think about it would be like an AC system. A larger air conditioner will cool a room to the thermostat temperature faster, not to half the temperature.
Basically, just like a home thermostat or hot water heater or oven, its temperature is being regulated by a sensor inside. The difference here is, unlike your oven or thermostat, there's no userfriendly way to change the set point temperature. You could certainly do it by replacing components, but which ones (and how many) will depend totally on that model's unique design.
locate thermistor, add resistor in serial or paralell depending on datasheet and/or measurements... This way you trick the iron it's at 275F.
How can l figure out how much resistance is needed to be at the correct temp?
That makes sense thanks!
>How can l figure out how much resistance is needed to be at the correct temp?
depends on the thermistor model, its sensitivity and stuff. You can put a tiny potentiometer alongside and dick with it until you get the right temp, measured with a meat thermometer or whatever. Then check the pot with an ohmmeter and buy that resistor.
Your using this for weed
how does a hair straightener help with ayy weed lmao bruh
You are correct l am trying to upgrade
I know what you're doing and this isn't the board for that
