Tiny thermocouple thermometer

Thursday, May 16th, 2019

Johnson Davies built a tiny thermocouple thermometer based on an ATtiny85 measuring boiling water: This project describes a thermocouple thermometer, capable of measuring temperatures up to +1350°C, using just an ATtiny85 and an OLED display. More details on Technoblogy.

Controller for soldering irons using the Hakko T12 type tips update

Friday, April 4th, 2014

sparkybg writes: Soon there will be a new version. The most universal I can think of. Isolated USB connection (HID class) for firmware updates, live data, and PID tunning. Will be able to recognize unlimited number of instruments - can read resistor, 1-wire EEPROM or 1-wire MCU in the connector...

Controller for soldering irons using the Hakko T12 type tips

Wednesday, February 27th, 2013

Sparkybg shared his controller for soldering irons using Hakko T12 type tipe in the project log forum: T12 have thermocouple in series with the heater with a voltage of around 9mV at 450 degrees celsius, so the voltage to the heater must be turned off to measure the voltage of the...

App note: Thermocouples, and design guidelines for AD59X TC amplifiers

Sunday, October 16th, 2011

Analog Devices has an app note on thermocouple basics, and some guidelines on how to design projects with their AD595 and AD594 thermocouple amplifiers. Temperature is the most frequently measured physical parameter. However, the techniques of temperature measurement are grossly misunderstood, often resulting in serious inaccuracies or meaningless data. Thermocouples...

Thermocouple to serial converter

Friday, July 1st, 2011

phirephly built a thermocouple with USB and serial interface: This is a device that takes a thermocouple temperature input, converts it into a digital value, and then spits out the temperature on a serial port, which you can then feed into a computer, or another microcontroller. This is a useful...
