It is not possible to use these JBC tips, at least without modifications to HW and/or FW. The C245 would need lower gain for the TC readout. I have read somewhere that C245 tip has 40 µV/C while WMRP has 15 µV/C. Maybe changing feedback resistor from 240k to 90k would work. The C210 has TC and heater in series, it would be good to add diode protection to opamp input, and change the temperature look-up table in FW. I don't have any JBC tips, so I can't help you more.

@@sidchip so you think tips c210 can be tried by adding a diode to the input of the op amp?

@@belloirawan9056 It can be tried, but I can't promise it would work properly. I think it would be better to build some other DIY station designed for JBC if you want to use C210 tips.

I am in the process of updating the wmrp build page, but it is not ready yet. Meanwhile, see the connection drawing on last page of the station circuit diagram. Markings on the wmrp board translate to this drawing like this: ESD = POTENTIAL HT = HEATER SW = TC1 / REED KTY = KTY 82

@@sidchip I was wondering, why isn't R17 on the BOM? I'm pretty sure I wired the handle properly but I don't have a resistor at R17. Maybe that's why its not workin?

​@@William51115Hello, have you been able to solve the problem with the glowing tip? I have the same problem and the WMRP is glowing red. I have already destroyed 2 tips and WMRT is also the same but only red on one side and the other tip doesn't get warm at all. It's normal that 12 volts is constant on HT1, regardless of whether tip is connected or not.

@@lukaszmadej2472 The problem was the plug. I tried a different plug and it worked

Actually I don't remember if it worked, it's been so long

Good to hear you got it working.

It's a lot of work to port the code for arduino or ESP32, and there's not much benefit. I you want to build the clock, it's easiest just to build it as it is, and get a PIC programmer.

Yes, there is 'toggle all' mode. It shows this kind of sequence: time, humidity, time, pressure, time, inside temperature, time, outside temperature, time, date. The sequence is chosen to be like this, so you don't need to wait long to see the time.

No, it doesn't work with WX series handles. You need WM series handle. But you can also build the handles yourself, on my website are step models of the handles so they can be 3D-printed, and Gerber files for the board inside the handle.

@@sidchip Thank you so much 🤩

If the connection is same as Weller tips (three terminals: heater, thermocouple and common), it maybe works. But temperature would probably be wrong if thermocouple type is not the same as Weller, that would need to be changed to firmware.

Ihaks tosi?

Hi Terry, not sure if you’ll see this but I’m interested in one of your boards. Let me know how I can reach you

Hi, it only supports the micro tools, which have thermocouple as temperature sensor (WMRP and WMRT). The bigger weller tools, e.g. WSP80, use a thermistor.

Code, schematic and layout are available on my website. Link is in the description.

@@sidchip but I do not found the code

@@andreiciora2765 It's under 'Firmware', see kair.us/projects/weller/index.html#firmware

Maybe, but some changes are needed. T12 has heater and thermocouple connected in series. The thermocouple input needs better protection. Also the regulator IC3 needs to be changed to type which can withstand 24V, e.g. UA78M05CDCYR. It is easier to build a project which was designed to be used with T12.

Ei varsinaisesti vaikea, mutta kyllä siihen aikaa sai kulumaan. Mutta eipä niitä tunteja harrasteprojekteissa lasketa.

Thanks!

If you have replaced your timing belt the the reminder light is no longer required until the next 150,000 KMs in which the light will come on again

Thanks! I'm also pleased myself how this project turned out, especially the hardware. I always try to make a simple design with low parts count, and this one really is such.

The only advantage is that you can build it yourself :) See also my newer video which shows the final version of my Weller station.

Thank you! I am glad you like it.

Valitettavasti tuossa on sen verran kova työ että en voi näitä myytäväksi tehdä. Rakennussarjaa elektroniikan osalta voisi ehkä harkita jos olisi tarpeeksi kiinnostuneita. Tässäkin tapauksessa kotelointi jäisi ostajan kontolle.

sidchip rakennussarja kiinnostaa! Tai edes valmis piirilevy

Unfortunately I don't have the schematics, they would have also helped me a lot while repairing the amp. My friend offered a few weeks ago that I could have the subwoofer because he doesn't need it anymore. I will ask him if he still has it. Then I could look for the resistor values. Are the burnt resistors on the main amp board or on the smaller board?

On main amp board most, but i believe on small board too, some are missing from factory i see. Some good pics would be great for comparison who`s missing by blowing and from factory, if it is possible. Ty so much :)

There isn't boot loader in the micro. You'll need a PIC programmer, e.g. PICkit2 or PICkit3. You can find more information from here: kair.us/projects/programming/index.html You can email me if you have more questions, my address is at bottom of my web page.
