Buck Converters

I recently bought a couple of buck converters off eBay for £1.16 each with free delivery from China. The one's I bought were these buck converters that I will be using to regulate a couple of power supplies for different jobs.

One of the buck converters from China.

After realising that not everybody knows what a buck converter is I thought I'd give a quick description here.

Tools and safety equipment.

I thought I would take a moment to go over the tools that I use and the safety equipment that is required for my projects.

Most jobs only need three tools; a hammer, duct tape & WD40.If it sticks and it shouldn't, WD40. If it should be stuck and isn't, duct tape. Otherwise get the hammer out.
