The Soldering Iron Controller was designed by Arhi (Bogdan Kecman) and shared under public domain in our forums. With his consent we developed our through hole version based on the 3rd generation of his driver.
The key to this universal design is the analog front-end which is capable of reading both Thermocouple and PTC temperature sensors. The SID features:
The hardware was developed by Arhi in the forum. His initial gen1 design used a PIC16F690 soldered on a perfboard. Since then he moved to the PIC18F2550 in gen2 and gen3. Images below are of gen2(left) and gen3 right), pictured above is our through hole version of gen3.
There are two versions of the firmware, one for controlling the device with buttons, another for controlling it via an encoder.
I found few minutes to redraw my soldering station driver so I can send it to itead before I go to vacation :) ... software is still not done (the old one works but is not using encoder, not reading thermocouple properly etc etc ..)
Upgrades from v1
1. thermocouple is read properly. The circuit used to get the K-type to go 0-5V came from microchip's app note
2. 3 buttons are replaced with rotary encoder with button
3. DS18B20 is added to read ambient temperature (thermistor returns difference in temp between hot and cold join so you need to know temperature of the cold join to know what is the temp of the tip. I decided to go with DS18B20 because I just figured out I have 10+ of those in the drawer)
Software upgrades (not done yet)
1. deal with hardware upgrades
2. use PI or PID instead of simple hysteresis to control tip temperature
1. make nicer PCB (I make ugly pcb's... especially when dealing with slow speeds like here)
2. there are some free pins that might be used for something ..
ONE SUPER IMPORTANT THING!!!
SID do not have a FUSE on the power input. You MUST HAVE FUSE!!! I do not use fuse on PCB because all fuses I have are for "wires" so I have 2.5A glass fuse on the wire bringing 24 VAC into the PCB. BE SURE TO ADD THAT FUSE. 2.1-2.5 A is what you need depending on what type of LCD you use. The whole circuit (48W heater + everything on board + standard lcd) takes 2100 mA MAX. On top of that you need current for lcd back light. I have here LCD's that pull 30 mA and I have some that pull 280 mA for the back light, and I used some earlier that pull a whole amper!!! Anyhow whatever you do ADD A DARN FUSE TO THE POWER INPUT!!! DO NOT TURN ON SID WITHOUT IT!!

DangerousPrototypes Version of the Soldering Iron Driver (all trough hole)
Fast cycle through the built-in 4-speed temperature (the default setting of 260-280-300-320)
Modify the built-in 4-speed temperature method:
1. Press the function key to enter the modification mode
2. Press the function key to select the number of modified files
3. Press the left, respectively, + and -, to be modified.
4. Press the function key to save and exit.
Power Supply: DC 12-24V, be careful not to reverse the polarity
Temperature setting range: 50-435 degrees
Note: when the iron temperature, equivalent thermocouple, polarity, if the pick the wrong line, and you can not control temperature, prolonged heating will burn.
The screen displays:
1. The four temperature settings (SA , SB , SC , SD)
2. boot time (rarely used)
3. T12 current temperature
4. Power supply voltage (Approximate values)
