[quote author="NECHTO"]Hello all :) What do you think about the possibility of installing this display[/quote] At least you'll need to make a new PCB with appropriate power circuit for it and add support in firmware. If you're lucky you'll have enough free MCU pins for it (and MCU time to drive it). What's the point to adapt this crusty old LCD? I saw on YT someone's managed to drive an LCD by Unisolder, but it was a modern COG one.
Oh, I thought it has a bootloader in it and as bootloader is already flashed there is no point to reflash it. Thanks, sparkybg, to clear this out for me!
[quote author="DinikS"] It started to flash firmware the screen on soldering station became dark and now it doesn't work even not defined by PC. [/quote] The same thing. Tried several times with no change. But then decided to flash (by PC software) firmware with integrated bootloader and it flashes just fine (two times).

[quote author="TilmanBaumann"] Ah well, Farnell in Germany is special. Very much not the element14 type hacker friendly establishment. They are stuck in their ways and actively and quite rudely get rid of non-commercial customers.[/quote] Sounds familiar to me! Was trying to buy at Digikey, but they've said I buying too many of positions, and they conclude it's a commercial order, which is have to be placed by a company. I've tried to argue, but they didn't even answer. Screw them! I've found a local agent which is provide access to a several major distributors for a reasonable charge, and consolidate all my parts in one package. Got all my components from both digikey and farnell without any unnecessary questions.
[quote author="JJAnderson"]what stand did you make it to fit?[/quote] Since initially I didn't have any stand, I've decided to try making my own, which resembles original JBC T245 stand.
[quote author="JJAnderson"]Be interesting to see how others have managed to integrate it into their stands?[/quote] Sensor board is simple relative to controller, I believe it's easier to redesign and make a new PCB that fits perfectly the particular stand than do a mechanic job to incorporate Sparky's sensor PCB.
It could be any IC in the path (IMO, especially I2C pot and DAC), also Vref, assuming all passives are OK. If working PCB set is available, one can just compare voltages along the signal path. On my board and display adjusting brightness also seems doing nothing, I presume it might be for 7seg LED display.
[quote author="protonoob"]Supplier reported that their was missing part #s in BOM, i am very new to this and took a look but couldnt find which were missing Has anybody had this issue from an assembler[/quote] Original BOM is not specific. You have to choose exact parts you wanted in the project and provide specific BOM to assembling fab. Also, it covers all PCB variations, you should remove superfluous parts from the final BOM.
[quote author="Iwanushka"]usually buzzers w/o generators beep constantly when connected to power, but mine produces low clicking noises...[/quote] It's oppositely, buzzer with generators do beep on DC, that's generator in it for. Q20/C57/R32 forms a low-pass filter, allowing using both types of buzzers without modifying firmware. On the other hand with simple buzzer C57 AC-couple square wave and R32 limits the current.
Iwanushka, may be you've soldered Q20 and D17 which are for buzzer with generator. 21 is displayed at the stage of power type detection - DC or AC and it takes some time on DC. Station beeps on boot, on entering menu or you may force it to beep via PC software.
[quote author="sparkybg"]Yes, you have to. PicKit3 can source upto 30mA, if I remember well.[/quote] Thanks for clarifying! I saw this number in the manual, so I thought that having two sources on one line is a bad thing, and decided to ask. But it turns out that power output from pickit has to be enabled explicitly in IPE, when it needed.
Another question. Does it make sense to put a multi-turn Rc2?
I'am going to flash the controller and have a question about powering. Do I need to connect power from back board to flash the firmware or my pickit3 clone will source it through ICSP?
I've bought an Wurth Electronics 651005136421 and it fits nice but not tight, though its row spacing is 1.8 mm instead of 2.2 mm in the footprint. It's the only difference. http://www.digikey.com/product-search/e ... 1005136421 I think mounting holes are made intentionally bigger than should be to accommodate slight differences between connectors.
[quote author="sebior"]Sparkybg. What diameter of copper wire should be sufficient for jbc t245 cartridges? I'm going to make tool by myself.[/quote] On the page 28 MadBekon reported dimensions of original cable.
