Variable O/P mod for Bushmaster TC-7530DC

[StanleyB]

Many people have asked me if it is possible to mod the standard TC-7520DC so that the fixed output can be converted into a variable output. The following pictures show one simple method of how this can be achieved. Additional text will be added to each picture as soon as I can.

You'll need four pieces of insulated wire of different colour as a bare minimum. But four screened pieces of wire are even better. The screened ends can then be soldered onto the ground plane of the PCB. I have used ordinary wire with pins at the ends so that I could take pictures and show the area where the ends of the wires should be soldered to. So the finish is not A1. It's rough at the moment for demonstration purposes.

Any interests yet in DIY projects for the BM? I have been playing with a few, but maybe we should wait till it's too cold to go out and do far more interesting things right now perhaps.

Must admit I'm surprised nobody got the itch to have a fiddle yet . You could be right though Stan, maybe more interest when the cold nights are here nothing better than trying a few tweaks.
