Hand Charged Working Clock

alright so i had a flashlight that was charged manually i had an idea of making an clock out of it.

Stuff You Need

so here is what you will need:
a manually charged flashlight
soldering iron
solder
switch (preferably but not required)
electric wire
screwdriver 
general purpose tools 
clock mechanism

My Flashlight and Taking It Apart

first take apart the flashlight and remove the case leaving only the necessary parts. I found that there were four main parts oone the leds two the switch three the circuit board four the rotating arm and charger etc i decided not to mess with that part  because it already had what i needed same with the circuit board. after looking at the parts i saw that it gave off 3.6v and would probably go up to around 5v if i was riding a bike at a normal speed which is right in the ipods butter zone of tolerances (i'm not sure about this but when testing it with the light the faster i spun the arm the more light which is expected so if i was riding a bike i assume that it would go up even more please tell me if im wrong and i would help out a lot later in this project)

A New Switch

the switch i came with worked but was permanently on the body so i desoldered it  and put a new switch i had on it  it was a basic switch i had you could buy one for like 99c at the shack just solder it on like any other switch and your done with that.

No More Light

so at this point its still a flashlight and isn't powering a clock unless you already made a solar clock so its time to remove the leds it was relatively easy all you have to do is  melt the solder and pull away the wire thats it.

The Old Clock

i found an old pocketwatch that still worked and all i had to do was remove the case and take the mechanism i did reuse the plastic face on my new clock you'll see once i get there.

what i did was use an old piece of cardboard that was gonna be thrown away and used it as the base punch a hole in the center put the mechanism in

Decorating

i spent like an hour just picking random stuff to be the numbers you can do whatever you want

Combining the Two Parts

i soldered the ends onto the pickups and it started working right away i tested with an led earlier in the week and estimating you will need to crank it for 30 seconds every 9-10 hours before it starts to slow down. and thats it combining two projects into one!
