yo stefan, thanks for the code you make.
such a genius.
Thank you ;-)
sir stefan, i have a problem with temperature display.
when i set the temp about 350°, the value displayed is not stay still like yours.
is there any fix for that?
@@RecehDIY This happens with some power adapters, especially if they are not adequately stabilized. You can try reducing the SMOOTHIE parameter at the beginning of the source code (e.g., to 0.02). If that doesn't help, increase the "5" in lines 362 and 367 to "10".
@@stefanwagner1759 already did that sir.
i thought there is a hardware fix for that.
thanks sir.
one more thing, can we have additional menu for c210 or t210 mode?
when we activate that c210 mode, the pwm output maxed out only at 128 or half.
i tried powering c210 tip with this station, it consumed too much current when using full pwm (255)
when i set it to 127, it is only consume 2.5 to 3 Amps at max.
i measured the resistance beetwen the heater pin, it is only 2 ohms, and will consume 6 amps on 24 volt source.
@@RecehDIY You can try to solder a big electrolytic capacitor at the power input, this might help to stabilize the whole thing. At the moment I don't have the time to develop the firmware any further since for me it does all the things I need.
I'd like to share your channel to my groups if that's fine with you. You deserve more subs and views.
Thank you ;-)
omg yes thank you!
Why you always made a very best t12 soldering station?
hello, I'd like to ask the easyeda platform, and contact someone who has modified it to be able to use the 936 handle. but unfortunately until now I can not comment on the platform. can you answer my question.
I want to ask, for handle 936. if in+ is connected to pin4 for 936 handle, then what about pin2 on 936? are pin4 and pin2 on the 936 paired with the p+ pinout?. I hope you can understand my question
Unfortunately, I don't have a 936 and I don't know the internal structure either. So unfortunately I can't help you with that.
Hi Stefan. Since I saw your video I made a few versions of this soldering station, from the first version were I had the problem with temperature readings to the third version which is more compact and it works perfectly, you can check itout on myRUclips channel. Now I want to make fourth version TS100 style soldering iron, I changed the fonts in the code in order to use the 0.91 inch display, all good until here, but I have a major problem, the rotary encoder. I want to use buttons instead of rotary encoder because is quite big and sticking out from the board like Eiffel Tower 😀 but I'm stuck because I'm not sure how to change the code in order to use the buttons. Can you help me out? I will happily share the the final result and all the files with everyone, especially with you if I manage to finish it. THANKS in advance!
Hi, in another project I replaced the rotary encoder with buttons while keeping the same menu control: github.com/wagiminator/ATtiny814-AquaTimer. Maybe this will help you (but note that a different microcontroller was used). Otherwise check out this project: github.com/Eddddddddy/T12-PD-SolderingPen

Very nice project! My congratulations!
I have the following question for you:
When you compile the * .ino file in the Arduino IDE, which board do you choose?
Then you program the Atmel 328 with the HEX file using a programmer, right?
Hi, you can use the * .ino with the Arduino IDE OR the * .hex with avrdude. If you want to use the Arduino IDE, install the following board definition in the Arduino IDE: github.com/carlosefr/atmega. Then select Tools> Board> ATmega Microcontrollers> ATmega328/328p. Then choose Tools> Processor> ATmega328p, then Tools> Clock> External 16MHz. Then go to Tools> Programmer and select your ISP programming device (e.g. USBasp). Then go to Tools> Burn bootloader. Open the ino file and click Upload.

hi stefan
I just made a pcb with a P version mosfet so it works for Jbc c245 but why is the screen saying 'error 000' and the tip is red hot..
do i have to do any special code to change it..
Thank You
Hi, if you want to use a P-channel MOSFET, you need a different circuit and you have to make the appropriate settings in the firmware. I don't know if the Soldering Station works with the JBC C245 at all. Basically it is intended for T12.
Hello!
I want to program the Atmega328 directly with the .HEX file. This should be done with a programmer and program SinaProg or AVRdudeprog.
I don't know what FUSE to choose. Can I help?
avrdude -c usbasp -p m328p -V -U lfuse:w:0xff:m -U hfuse:w:0xdb:m -U efuse:w:0xfd:m
@@stefanwagner1759 Thanks a lot for the answer!
Therefore if I use SinaProg I will use the following FUSEs:
LFUSE: FF
HFUSE: DB
EFUSE:FD
why the display still error even already plug the solder, temp still zero & the mosfet over heat when plug the solder, whats the problem?
I can't possibly say that from a distance, sorry.
Tell me what could be the problem. Using the c245 tip, the station can completely freeze and heat the tip to red. Only a reboot helps. Can you think of something with this?
Hi, the soldering station is designed for T12 tips. I am not familiar with the C245 tips. Perhaps these are internally structured differently than T12. Since I unfortunately don't have any C245 tips either, I cannot test whether it is because of that. However, you can check whether the voltage supply for the ATmega is stable.
How is the board sensing the temperature? and how is it changing the "state" (temp reached, temp low)?
A temperature sensor (thermocouple) is located in the soldering tip and is connected in series with the heating element. When the heater is off, the thermocouple generates a very small temperature dependent voltage. This is amplified by the OpAmp and measured with the ATmega's ADC. The software then calculates the temperature from the measured voltage.

Hi, I suspect the problem is with the 7805 voltage regulator. Please measure the input and output voltage on the regulator when the station is only powered with 20V. If there is 20V at the input, but not 5V at the output, then the regulator is probably defective and must be replaced.

Hi, I have a problem with the temperature reading from the thermocouple. The error is about 50 Degrees. This leads to the fact that the top of the soldering iron is not sufficiently heated and the mosfet cuts off the power of the heater. The display constantly changes in value and does not calm down. Has anyone had this problem and what could be the solution?

Hi, I think you can built the whole station out of DIP/THT components. Maybe you can use some kind of prototyping board for it. In fact, I've already thought about designing a PCB for a THT version, as I've been asked about it a lot. However, I don't have the time for that at the moment.

Hi, regarding the rotary encoder, try to compile the sketch with the setting "#define ROTARY_TYPE 0" (line 63 of software version v1.8). You should definitely use a Schottky diode, normal rectifiers (like US1M) tend to overheat due to the higher forward voltage drop.

Hello! I made your station option but I used Arduino Nano.
I have the following problem. Many "dance" display values. If 320 degrees is set - goes to 380 sit down to 280 and up again.
I used a LM358 operating amplifier. Then I changed it with MCP607, which has very good parameters. But there was no change. You have an idea of what this is due. For PID I use the library you apply.
Hi, these are indeed quite high fluctuations. The Arduino nano shouldn't be the problem, but I don't know your other wiring. Noise may be induced in the signal line. The power supply also plays a role (try another one). You can also set direct control in the menu instead of PID, maybe that makes a difference.
@@stefanwagner1759Stefan, thanks for the answer.
I have achieved perfect work at 19 V power and direct regulation - no PID.
Upon power supply 18 volts and 20 volts no longer works well. Why is this power so critical?
And an idea from me. Can you change Software so that it reaches the set value to be displayed and no longer changes. It does not matter what is measured for temperature. So the Chinese soldering stations have been made.
I think that has to do with the fact that a fat capacitor is missing at the power input (for reasons of space), which stabilizes the voltage, especially when controlling the heater with PWM. Some power supplies handle it better than others. You can add a 470µF (or higher) and 50V capacitor to the power input and see if it works better.
For the display, take a look at line 350 of the source code (original v1.8):
if ((ShowTemp! = Setpoint) || (abs (ShowTemp - CurrentTemp)> 5)) ShowTemp = CurrentTemp;
You can increase the "5" significantly, e.g. to "20". This stabilizes the display of the temperature (the displayed temperature only changes if the measured temperature deviates by more than 20°C).
@@stefanwagner1759 Stefan, thanks for the detailed answer. Capacitors did not improve the work of the station. I changed the hysteresis of 20 as you have recommended. So visually was good. Only the rapid change of inscriptions Hold and Worky teasing the eye. So I removed them when the desired temperature was reached.
You can also change the hysteresis for the "worky" flag in line 355 from "5" to "20".
Good day!
Can you add two things to the firmware?
Encoder reverse (all my encoders work the other way around) and
so that you can limit the PWM (limitation of the ability) the jbc has a large current at start and my power supply goes into protection.
Can you add to the firmware?
If you use the orginal v1.8 firmware, try the following changes in the source code:
- for reverse rotary change line 428 to: countStep = -rstep;
- for PWM limitation change line 113 to: #define HEATER_ON 50
and line 254 to: ctrl.SetOutputLimits(50, 255);
change the "50" in both lines to a value that matches your needs. Keep in mind that a "0" means heater is fully on and 255 heater is fully off (assuming you're using the N-Channel MOSFET configuration).
@@stefanwagner1759 Yes, it works great! Thank you. JBC is better working on the PID on the other goes rides the temperature when heated 5-10 degrees later falls and jumps again
@@user-ur2bf4up8r Depending on the power supply used, sometimes direct control works better than PID.
hi can i use KSGER handle? or i need to reroute the cable?
Hi, I suspect they have the same pinout. Nevertheless, to be on the safe side, you should check it with the multimeter. The earth pin should be conductive with the soldering tip. There should be a resistance of around 8 ohms between + and - pin. Depending on the inclination of the handle, there should be either a conductive or no connection between SW and -.

2.6: changed charge pump diode D1 to avoid overheating, 2.7: changed BJT Q1 to a more robust one
HEY!.
I managed to make it work, it works very well
Is it possible to use a 0.49 inch OLED display?. Can it help to change the code to use the 0.49 inch oled?.
I want to use a different box that requires a smaller screen.
Thanks.
Hi, if the display also uses an SSD1306 controller, that shouldn't be a big problem. Of course, smaller fonts would have to be used so that everything fits on the display. Unfortunately, since I don't have such a display myself, I can't test it either.
@@stefanwagner1759 Yes, it uses SSD1306. I will try using a breadboard.
Thanks.
@@jairosantos You can try to change line 200 in the source code to: U8GLIB_SSD1306_64X48 u8g(U8G_I2C_OPT_NONE); For the fonts take a look at github.com/olikraus/u8glib/wiki/fontsize
@@stefanwagner1759 I will do this. I will give feedback when it works correctly. Thanks.
@@stefanwagner1759 One more question, if it doesn't bother me.
I intend to use a ceramic crystal smd 16 mhz SMD-3 16,000 mhz (CSTCE16M0V53-RO) to reduce space, use atmega 328 au, with bootload of arduino uno. The uno uses quartz crystal.
Is it necessary to use fuses other than the arduino uno pattern?
Thanks.
Can we use the hakko 907 soldering hand?
Hi, I don't have a 907 but as far as I know the temperature sensor is not connected in serial as in the T12 soldering tips. So I think it will not work "out of the box", you need to make some small modifications to the design in order to make it work.
As i know, 907 works based on 24vac not vdc
@@indrasutarman Wrong. The soldering iron doesn't care if you feed it AC or DC since it's just a resistive heater. So the AC/DC thing is only relevant for the control of temperature or reading temperature i.e. are you comfortable with a triac control (AC) or would you rather PWM control a MOSFET (DC).
thank you for sharing ..... please make a board which is also compatible with "JBC cartridge" , i found one station design in dangerous prototypes blog , please make it for us
Hi, unfortunately I don't have any JBC tips. I chose the T12 tips because they are super cheap and come in a wide variety. So for me there is no reason to build a soldering station for other soldering tips.
@@stefanwagner1759 Great ... thanks for d reply
Hi i am working on this project ordered all of the part but cant figure it out how i can connect t12 handle parts
Hi, if you have a T12 handle with an aviator plug (the cheap ones you can buy at aliexpress) then you can connect it as shown in the description on the EasyEDA page. If you have a handle kit you can watch the following video: ruclips.net/video/DcmiFfuZw38/видео.html.
@@stefanwagner1759 many thanks, i got it. Also i cant find the irlr7843 in my area. Can i use irfr540z ?
The irfr540z should also work, but it has a higher resistance (RDSon) and is therefore not as efficient.
@@stefanwagner1759 can you give some alternatives for irlr7843? i dont want to order from another website and pay extra cargo.
without guarantee (not tested): HY3403D, WSF30100, NCE30H15K, SE30150B.
Hello!
I want to ask about the Sleep feature. When is this feature on:
- when SW is connected to E
or
- when SW is not connected to E
This matters to mount Tilt Switch in the handle.
Hi, for this soldering station one side of the tilt switch should be connected to GND (P-) inside the handle, not to Earth (E)! The other side is then connected to the SW pin on the soldering station via the connection cable. It does not matter in which orientation the switch is installed. The software detects a movement of the handle when the state of the switch changes (from "on" to "off" or vice versa). If the handle is not moved, then the switch remains either in the "on" or in the "off" state.
@@stefanwagner1759 Thank you very much for the answer!
I was worried about the following.
When not working, the handle is placed in a stand with the top below.
In this position after time the solder "will go to sleep."
When working, the situation is the same (with the top of the handle below).
Is there no danger of the solder to sleep?
@@vencislavvankov4897 In theory, this could happen if you hardly ever move the handle for the set delay time (5 minutes for me, but it's adjustable) while soldering (also e.g. when cleaning the tip). This has never happened to me in practice. Even if that should happen to you, the soldering station will alert you with a beep and you will then have to move the handle a little more clearly to reset the sleep timer.
Stefan, thanks for the detailed explanations!
You always answer the questions and explain very detailed!
I think this will be useful for others who assemble a handle for the T12 soldering.
Your project is wonderful!
Thank you ;-)
make with c210 cartridge please
I don't have any c210 cartridges, so I cannot develop for it. Sorry.
Ok steven. I hope you can make it later. Thank you 👍

Hi. I really like your project.
Can you share your source code ?
Thank you !
Hi, thank you. You can find the source code at the bottom of the EasyEDA page or at github.com/wagiminator.
@@stefanwagner1759 Thank you. But i have a question :
In the OPAM LM358, why OUT2 pin connect to IN2 - ? . And IN2+ pin conncet to VCC and GND through resitor ?
I don't know how it working ?
Can you explain me ?
@@stefanwagner1759 Because i think part B of LM358 IC do nothing. Is that right ?
Exactly, an unused OpAmp should not be left floating.
@@stefanwagner1759 thank you !
Can I use IRFZ44N as mosfet for this design?
The MOSFET should work fine without any further changes.
@@stefanwagner1759 Thank you so much!
