The fan controller found a "home". (project box) Now this enclosure is more than 20 years old. I dug it out of the junk box. It once housed a transistor tester which I constructed. The enclosure is build out of double sided PCB. Those were the days when copper clad PCB was still cheap. Today it will be an expensive venture to build a PCB enclosure. A little sanding and a cote of spray paint and it is as good as new. Herewith a few images of the fan controller installed. The only thing that needs to be done is to attach the thermistor to the radio heat-sink and then I can activate the 145.550 RF link.
Thermistor installed on Motorola Link Radio
Finally: You can ask me many things but do not ask me to install a project in a project box/enclosure. I hate it!! It is a time consuming venture even if you find the correct size enclosure. Maybe it is time that I should invest in a 3D printer to print my own project boxes. Who knows Christmas might come early this year.
