Project logs / Re: Really universal soldering controller
Tried it a again to make sure, now it says 1/4th power. Still hard spikes tho.
No idea why it showed FULL the last time. C210 was connected with tip inside.

Maybe i didnt connect it properly and didnt realize, not sure.

The display shows C210 and the scale at the bottom peaks at 40W.
Maybe its not really using 1/4 Power and just shows it?

Im in the process of building a 2nd Unisolder, maybe problem is fixed there. But this will take quite some time untill its finished, and im using the exact same parts as for the one im using right now.

Is such an insane RdsOn even necessary?
Couldnt you make the argument to go with even worse MOSFETs and safe a buck or two?
In reallife scenarios nothing is comming even close to 5min submerged in water.

What i wondered for some time now:
Would a one channel version of Unisolder be possible with little modifications to the board, or just leaving parts unpopulated?
Most people are using it as a one channel version anyway i guess.

Best Option to test the Temperature i have is some cheap chinese solderpaste wich says it melts at 183°C
C210:
With the sation set to 180° it start to melt, with the overshoot that happens this seams reasonable.
C245:
Station set to 182°, not melting, set to 184° melting. Thats pretty on point.

So the calibration should be fine.

Yes i have an osciloscope.

Transformer is rated for 150VA, dont have a datasheet tho.

Why is ADC spiking up again, when Temperature is already above taget and shoots further above target?

Below ist C245 wich looks fine to me.

So wiring should be wrong somwhere in the handle intself.

The sleep board has been working for three years, I don't notice any problem 4001+bss138+560+10M :)

Just to clarify, you are talking about this schematic:


Using this board?

If someone don't want to use diodes, just to short the pads. BAT46W has a bit better specs for that purpose and pads are drown for it. 1N4148 SMD fits also.  Here it is:


I guess the connected mainsearth of the handle drives the gate inputs low? So i have to connect the tip to earth? Dont have it connected and the moment.

Im currently useing this type of holder:


Does anybody have a link to a cheap version of this type of holder (only the top holder piece):

I have seen it in a few builds here, and Mounting it to the Unisoldercase would make for a nice slim build.


Also, my C210 is pretty unstable. Temperature fluctuates around 20°, using the latest firmware by sparkybg. Once its dropped below set temperaure it overshoots quite a bit. Display indicates, that it only uses 1/4 power
