For reasons that need not concern us here, I have joined the Model Electronic Railway Group, (MERG).
This gives me access to their range of kits. Many are complex projects that if I'm honest, are over my head, or at least offer facilities that I'm not likely to need for the sort of layouts I build. However, there are also some pocket money numbers and as it's been a while since I did anything like this, I'm starting with one of these.
The PMP 10 Speed controller is connected to a 12V DC source and provides a variable output from 1.2V to 12V. Suggested uses are running operating accesories such as a windmill, variable voltage supply for the workbench or even a simple railway controller.
In the bag for £1.32 is a piece of pre-cut veroboard and the required components. Instructions are downloaded from the website. The builder needs to supply wire and solder. Quite frankly, for this money, even if you ruin it, it's not the end of the world.
I'll heat up the soldering iron and let you know how I get on tomorrow.
