@romekplay That´s have been discussed before and the recommendation is to use 0.96 inch display for calibration There is much noise with bigger display,but unisolder will work ok.
Hi, I am just trying to use big OLED display 2.42" instead of the small one. It seems to be working fine, but when I go to calibration menu "ADC" and "R" items are fluctuating pretty rapidly. https://youtube.com/shorts/z_VYdrxF818 Do you think is it ok and it has no affect on soldering station? Does anyone has the same problem with the 2.42" display?
yesterday I was doing some soldering, went away and when I came back, the thing was completely dead.
I did a quick check, it seems at least Q1 is dead (no usable voltage behind it + burn mark on it), unfortunately I have no spare one so I had to order some and wait.
I'm wondering whether it'd be possible to remove Q1 (and maybe D12?) and temporarily bypass it to check whether there's more stuff that died. Do I risk killing anything by doing that?
Also any idea what could've killed Q1? Is it common to die?
Thanks!
Hi, I have spare Q1 and D12. I sent you a message.
Ok, so maybe I can provide more details. Maybe relevant, maybe not. When I connect handle for hakko tips with no tip inserted or I just connect ID resistors for Hakko, display shows zero on bargraph. When I connect handle T245-A with no cartridge inserted or I just connect only ID resistors for T245, display shows full on bargraph with repeatedly flashing pwr sign on the left. I checked videos on YouTube to compare it to my Unisolder and I found one video with the same behavior regarding bargraph when T245 is connected with no cartridge inserted https://youtu.be/-v7KMNc_rJk?t=2786
Hi, I just built Unisolder. I am having strange behavior with T245 handle and C245 cartridge when I try to swap cartridges. Handle is recognized as JBC C245, which is ok I suppose. I insert cartridge and it heats up. Then I remove cartridge and consequently I insert it back (the same cartridge, still hot) and display shows “Heater open” I must wait some time until Unisolder recognize the cartridge again. When I swap cartridge with another one, cold one, it is recognized with no problem. Does anyone have the same problem? Is there any issue with my Unisolder or is this problem with hot swap in this design of Unisolder? Thanks for any advice.
