I won't be asking alot, just to return the material and shipping costs. --- End quote --- If you keep it very low, there could be someone here (not from Europe) who wants to buy a kit. Because in Europe you can get the analog JBC BT-2BWA with Handle & 2 chisel Cartridges for 249,- Euro's. Without the Handle and the 2 Cartridges you pay plus/minus 150 Euro's. The station is new and fully factory warranted. I'm personally more interested in a analog BT-2BWA or digital CD station hacked to use with the 2 JBC TweezerTools. ;) --- Quote from: 0xdeadbeef on June 02, 2014, 06:08:18 pm ---Probably not what you want to hear, but but just for info: you can get a new JBC station with T245 handpiece plus two cartridges for less than 250€... Ok, it's analog but still tempting. eBay (including VAT and shipping in Germany) http://www.ebay.de/itm/JBC-Lotstation-BT-2BWA-analog-mit-Lotkolben-T245-A-und-Zubehor-/231246976280 Webshop (including VAT, excluding shipping) http://www.chiemtronic.de/produkte/jbc-loetstationen-loettechnik/analoge-jbc-loetstation-bt-2bwa/ --- End quote --- Also available here: http://weidinger.eu/shop/loettechnik/jbc/jbc_loet-_und_entloetgeraete/jbc_loetstationen/wl26830 |

It seems very complicated. I have done solder stations with A1321 handles (4 wire, with thermcouple as a temperature sensor). Power comes from a laptop power supply (20v), and NE5532 as the thermocouple amplifier (with some avrs having 20x / 40x adc, you don't need that amplifier at all). No display however, other than an RGB led to indicate status. Temperature kept within a 1c or so. I may build one with 4-digit led display just for fun - the firmware is already written. |

It is not complicated. It's only a prototype, so it looks the way it looks. Esentially it's 2 MOSFETs, 3 optocouplers, an opamp a microcontroller, some shift registers, basic power supply and a handful of passives. |

And maybe you can make your controller compatible with the JBC Tweezer-tools, or must i buy and use 2 separate controllers from you for one tweezer-tool (with 2 tips)? |
