Soldering Station Analog

WTH is this?

A D.I.Y. cheap temperature-regulated soldering station powered from a laptop adaptor. It is developed in a hackerspace@budapest. It can be purchased as a D.I.Y. kit also, see the details here. This is an open-source project. The printed circuit board and other informations are published here. The project has a unique license.

Build notes

In order to build this equipment you need to make the PCB, get some components, a laptop adaptor 19-24V, the professional iron "IRON-N" for 6.5 EUR and solder the PCB.

Drilling

The holes are 0.8 mm except the - DIN-5 connector, the ground connection (derives from the central pin of the DIN-5 connector), the transistor — these holes should be 1 mm - The big potentiometer’s holes should be 1.2 mm - The other holes at the edges should be 3 mm and the big one 6.5 mm - The holes on the plastic box should be 6.5 mm

Component list

There are 3 variants of the equipment: the boxed version with RETRO and ELECTRO styles, and the BOXLESS version which is cheap.
