Irony problem

Is there a way to find the temprature (without a microcontrollers

Are you thinking of using an analogue meter to display the temperature.?

The only other way is a 7 segment display, but in reality a uP is easier.

Did someone forget solder? It's like evaryone are talking and none remembers the solder(I light my tube recently)

Now I think I'll make changes

-Use of a 3 digit display with microcontroller(if possible without it in my next change)

-Use the thermistor on the barrel and calculate temprature accordingly(not sure about one thing- Will the temprature of tip= temprature of barrel? If not microcontroller is a must unless proven otherwise)

Thanks a lot for replies

Temperature Sensors, at least the ones without internal processing, change resistance or output a voltage. They do not output a temperature per se. The processor maps the range of voltages that are output on to a range of temperatures to produce an output. As long as there is a correspondence between the range of sensor outputs to actual temperatures we can call it anything we want. Look at our ability to display the temperature as degrees Fahrenheit, Celcius, or Kelvin. All different but talking about the same temperature. In the case I described with the heat resistor our sensor would sense 100 C but our display would display 300 C. There would be no need for any conversion chart.

Sure, but you're impeding it's ability to read a temperature. You go from reading the temperature of the flame to reading the temperature of the pot you're heating. In this case the flame is the iron and the pot is the leads or anything you are soldering. That's like guessing the volume of a stereo from outside your house. All you'll end up with is, going from "that radio is loud" to "is it on?".  Plus dealing with environmentals, an air conditioned room will affect the temperature probe more so than if it were on/in the heat source. Even if it were encased in the buffer.
And with the delay of heat transfer from your heat source, the best you can hope for is to measure your holding temperature.

The solder would flow on the tip and damage the thermistor. So i planned about mounting it to the barrel.

I would have hollowed out the inside of the tip and mounted the thermistor inside.

I hope you get it working with a thermistor eventually. I've decided to go with one of these. REX C100 Dual PID Digital Celsius Temperature Control Controller Thermocouple | eBay

It uses a thermocouple. But for it's purpose, it's may end up being worth it to me.

Here this goes up to 750C and $28.00

Dear: royston

You probably use a rotary switch to control the amount of electricity flowing in. Controlling the amount of electricity flowing will control the temperature. Then all you got to do is to convert watts to temperature. You can do that by using conversion that I found here http://www.unitconversion.org/thermal-resistance/kelvins-per-watt-to-degree-fahrenheit-hours-per-btu-it-conversion.html. Also I don't know much about watts to Fahrenheit but you know that your Iron has specific heat. You will need to include that in the conversion or test your Iron. You can test your Iron by recording the temperature from different watts. To do that you will need a thermometer to record the temperature at different watts. I wish you good luck and I will make sure to watch your video because I am in a need for an Iron.

Perhaps, you should buy a nice soldering iron and put a card up at your local music shop offering to help electric guitarists change out their pickups and pots.  Then you might recoup your investment quickly and not have to worry about being out-of-pocket.

Does this work?

I mean, there is many guitar shops around my location, but i didn't think that pickups got changed very often.

Anyone do any of this?
