DIY Temperature Controlled Solder Station
The Platino Solder Station presented back in 2015 received wide acclaim and not just from the Elektor readership. In good engineering tradition, the very fact that the original project worked off the bat was a key motivator to seek enhancements for the intrinsic design. The concerted effort and thought that went into this produced a completely new design which is described here.
