Power Supply
I have been looking for a power supply for my electrophoresis other than batteries. I have been using an old train transformer, but it is very slow or 3 to 5 9 volt batteries, but is very costly. While searching the internet I found this:

Now any time you play with a 120 volts you should be very careful. Here is a file for Basic Electrical Safety:

I will be building this power supply and trying it out. I will talk about this in a later post. If you build be very careful.
