Here's a picture of the latest prototype which was developed during Christmas 2007.
The idea was to create the first candidate for a production PCB.

There are some things that will be changed to the next version (the first real production unit):

• Some component mounting holes have the wrong drill size on this prototype.
• This prototype only runs on 230 VAC. The next version will hopefully run on 115 VAC also.

With the temperature setting switch it is possible to set the desired temperature between 80 °C (176 F) and 112.5 °C (234.5 F) in 0.5 °C (0.9 F) steps.
