Run LEDs From 1 Volt

Having made a couple of home-made batteries which only produced about 1 volts each, I realised that it would be useful to be able to increase this voltage to power a LED light. You may be thinking ‘connect 2 in series’ but there are disadvantages with this.
This voltage booster increases the voltage. It has leads with alligator clips, so it can be used on different projects.
