TITLE:DC CONVERTER AND ELECTRICAL STORAGE FOR SHAKE-A-GEN (example)
CONTAIN: What is the shake-a-gen? Remember my previous post about how to make an homemade generator? So, the design has another external link about the storage of DC power from the AC generator. This generator is called an AC generator. This means that the
voltage appearing at the two wires alternates between + and -, and -
and + each time the magnet goes from one end of the can to the other. Based on the website that I found, they used a device which includes a few components to rectify the alternating
current (AC) from the shake-a-gen, store it in a capacitor and convert
it into a steady direct current DC. The output can be used to run a low
power device. It is also wired to an LED which lights as the generator
is moved and also for a little while afterwards. An LED can also be
wired across the generator connections so that both the AC and smothed
DC power can be observed.
Below is the diagram for shake-a-gen storage device.

ANALYSIS:
PARTS LIST AND TOOLS
4 x OA91 germanium diodes
1 x 10,000 uF electrolytic capacitor (16V)
two LED's (red and yellow say)
1 x 1000 ohm resistor
1m of twin wire (bell wire) to go from generator to the circuit
soldering iron and solder
CONCLUSION: This post may be helpful to improve my understanding.
