content: You will not reproduce the hand piece or the soldering tips unless you have access to a well stocked machine shop and excellent fabrication skills, but there is no reason to think you couldn't reproduce a compatible base station and controls. I seem to recall Mike looked into that at some point...?

content: Quote from: IanB on May 27, 2013, 08:32:57 pmWell my Idea was to use a Hakko 907 handle but build the heating electronics setup like the JBC ..

content: The key functional element of those good soldering stations is that they have a temperature sensing element and a heating element very close to the tip of the iron, a low thermal mass, and a very fast temperature control loop with plenty of power behind it to hold the temperature steady.Lesser irons have a big lump of copper in the tip to hold heat and compensate for a slower temperature control loop. It takes them longer to heat up and longer to recover if you suck heat out of the tip.In contrast the higher quality irons make a virtue ofnothaving a big lump of copper in the tip. Instead, as soon as you draw heat the drop in temperature is noticed and the iron instantly ramps up the heat supply to keep the temperature constant.

content: Wheredoya get that handle head by itself and whatsit cost? I can easily build a MCU circuit with a thermocouple amp and power supply and a LED readout and pot to adj etc. for this powerful pencil. But what arrpox. cost of the handle and changeable tips?

content: google "soldering pencil" plenty should turn up,for something more specific in Sydney Australia, there is a large distrubuter known as "WES Components" and they have all sorts of replacement parts and pencils, and will give retail prices over the phone,
