Haven't pulled it apart yet but attached a pic of what should be the PSU board which I found online. 17IPS62 23521004
E: Just took a look through the vents, it looks like the board is actually a 17IPS72....Last edited by spleenharvester; 06-18-2024, 12:19 PM.

Toshiba/Vestel 50UL2063DB rebooting whenever it feels like
We've had this one about 4 years now, for the past year or so it's been rebooting roughly once a week. Always in the middle of playback from an Xbox Series S. Not sure if hardware or a software configuration issue as we changed our setup a while ago.
I've tried putting the latest firmware .bin on a FAT32 formatted 4GB USB2 stick, 28617342_MB230_TOSHIBA_QUI_KYLO_V051300_SVN_328380, which I am 95% sure is the correct file. I then tried all the usual Vestel tricks (plug in USB stick, unplug TV, plug in TV while holding OK and/or power button). No response, it just boots straight to the...

Dremel 8220 turns on when it feels like it
I've got a Dremel 8220 here that's had maybe an hour's use on it tops from brand new, so the brushes are definitely fine.
The fault is it just doesn't switch on sometimes. This can be after you've just used it or from cold. If you pull the battery and re-insert it will fire up straight away, every time, so it doesn't seem to be a physical issue with the power switch. Once on it works perfectly until you switch it off again, then it's pure luck whether it fires up again or not without pulling the battery.
I've not really worked on these kinds of tools before so would appreciate...

Cheers redwire. Think I have fixed it all, attached V04 schematic. I've checked and rechecked the ADC section many times and can't find any errors, maybe someone else with this board can confirm.
As an aside, I've received my replacement T12-958v2. Interestingly although this one still shows as software V3.2S and has identical PSU and controller boards it does not suffer the INVERT error....

Lol this piece of garbage made it a whole 3 uses before blowing the element. I need it to limp along another few months til I can afford to replace it with one of the nice KSGER ones. The station is 700W, do I need to replace it with another 700W element or is there any benefit to replacing it with a higher wattage one? Also what's the insulation material, I'm guessing some sort of fiberglass? (E: It's mica paper, probably why my hands are so itchy now lol)...

macklij[USER="545441"]macklij[/USER] The board already has header pins to use with an STLink which makes life much easier - just solder a header on and connect any STLink adapter, making sure the station isn't powered up at the same time. The T12 CFW github page has a really good

Hi all
My board hasn't actually got a version number printed on it at all, but software reports HW revision 3.2. I've fixed the BOOT0 and RTC issues in my schematic (I had BOOT0 connected like that as the traces are physically connected to it, but as someone said on EEVBlog it just seems to be grounded out anyway).
R6 is definitely 5 milliohm, has R005 printed on it. I have rechecked and am also convinced the other resistors are correct in that part of the schematic. I've added a missing 4K7 to ground on V+ but I don't think that makes a difference as it's not...

Yeah more than likely there are some errors, I have no electrical engineering background so don't really have any idea what I'm tracing. Which bits are wrong as I'll correct them? Have found the RTC missing 3.3V assignment since,
All the connected I/O pins are there, David was able to produce CFW (well not from this one but someone else's which got the same pin assignments as mine). I mostly finished it for fun really!...Last edited by spleenharvester; 05-20-2024, 09:05 AM.

Hi all
Long story short I tried to flash CFW and bricked it - turns out this is a brand new T12-958 board design with different pins, and until a few days ago the original firmware dump was unavailable. Myself and someone else over EEVBlog traced the pins and got a relatively complete schematic of the controller, and David kindly released a new CFW for it that I'm told is working. But I accidentally killed my T12-958 in the process of tracing the schematic so that's the end of that!
Quicko have actually released a 'T12-A' station that is designed specifically for Milwaukee/DeWalt/etc...

Yep INVERT on battery power with cold heater cart below about 100C. The temp is increasing as normal before the error so unless something is happening in a split second I think we can rule that one out.
I'm going to try the cap thing and if that doesn't work I'm going to flash with custom firmware, will update

Cool thanks I'll give that a go.
Yeah first thing I did was bin that power switch lol. I [URL="https://imgur.com/FlHipk0"]replaced it [/URL]with a metal DC jack, torpedo switch (one of the decent ones with screw terminals) and 14AWG wires. I think lowest rating in there is 10A max but better than it was at least.Cool thanks I'll give that a go.

It's interesting this battery can run a 700W hoover no problem but struggles with this. I don't really understand enough about it I think. Quecoo have concurred it's something to do with the battery and someone elsewhere thought the [INVERT] error might mean it thinks it's not getting enough power from the AC/DC converter, which makes sense considering it won't know which one it is running from.
What cap do I need/whereabouts do I need to put it? Battery is wired to it with 14AWG wires. I wonder it is worth putting one inside the battery adapter casing so that it's already charged...Last edited by spleenharvester; 05-10-2024, 09:47 AM.

Making a Handskit hot air station a bit less stupid
I bought one of [URL="https://www.aliexpress.com/item/1005002890887241.html"]these [/URL]as it was the only one I could find that is compact enough to fit in my toolbox (though I've since found [URL="https://www.aliexpress.com/item/32844169715.html"]KSGER make a substantially safer looking one[/URL]). It's one of those fan-in-handle things that has the 230V element in the handle. Quecoo briefly sold a [URL="https://www.aliexpress.com/item/1005004884759470.html"]similar unit [/URL]but discontinued it.. maybe they couldn't find solutions to these problems. I'm aware...Last edited by spleenharvester; 05-09-2024, 09:24 AM.

Thanks both, that's good to know,
With the Einhell battery the power is a stable +20.9V sagging slightly to +20.1V under load. The DC adapter behaves similarly. Neither is tripping the low voltage cutoff which is set at +19V.
Quecoo do a version that fits Worx, DeWalt, Makita, Milwaukee and Devon batteries, so presumably it is possible to tool battery power them (granted no one has done a teardown of these yet): [URL]https://www.quecoo.com/products/t12-cordless-soldering-iron-station-for-milwaukee-dewalt-makita-devon-worx-18v-battery-temperature-adjustable-auto-sleep-low-voltage-protection-oled-digital-display-tool-only?variant=42322818793612[/URL]...Last edited by spleenharvester; 05-09-2024, 08:49 AM.

Gotcha thanks that makes sense, I'll stick a 1M resistor on T+ to VCC, and a 100uF between VCC and GND. Is a 1/4W resistor sufficient in the former?
My T12-958 has no version marking on the PCB but reports HW version 3.20 and SW version 3.2S. I've attached some pictures for anyone else who stumbles upon this thread. The only modification done to this unit is moving the green earth wire from the connector (where it didn't actually connect to anything) to the GND pin of the GX12 connector (under the hot glue I added), everything else is stock. There are two 680uF 35V caps and a choke...

Thanks, this sounds promising. I'm struggling to figure out which pin that is on my GX12 connector you're referring to - I have T+, T-, GND, NTC, and SLP, is it one of those?
There's no 100uF cap on the controller board or on the power side, only one 680uF cap - do I just need to put a 100uF 35V electrolytic across +24V and negative?...Last edited by spleenharvester; 05-08-2024, 01:35 PM.
