Hi guys,
Been out of the experimenting for ages, but I now have some free time, and would love to get back into chemistry cos it used to be my favourite subject when I was a youth. My goal is to create a great home made battery, and to try lots of different electrodes/electrolytes (which are fairly easy to get hold of), in all sorts of configurations. In addition to ordinary batteries, I'd like to have a go with home made rechargeables, and with Earth batteries...and perhaps some other ones if there are some good suggestions. Here is my first attempt, with what I had handy. Magnesium, Graphite, and drain cleaner. I manage to get LEDs, neons, and even a 4W CFL tube (just), but this is with the help of my flyback oscillator (like an exciter circuit, but no resistor, and uses a darlington pair arrangement of TIP 31C). 1.86V and 15-20mA with no load. I thought this was great with no thought of design - just chuck the metals in the drain cleaner. With a lot of improvements, could be much better.

I have found a couple of people on youtube who do great videos on this topic. Here is a guy who helps you make your own graphene, if you are feeling like trying some a bit exotic. I fancy making the Nickel Hydroxide, as I gather that its essential for the old Ni Fe batteries that Edison developed. I'll try and make some soon. Anyway, here are some great links if anyone is also into battery stuff.
