Hello again guys! Today I'm going to show how I made my hand crank flashlight.
First, I want to talk about the breadboard. The breadboard is for connecting circuits with wires and diodes and other things. If you wanted to connect a light and wire together in line 1, put them both in line 1 in any of the 5 holes. There are at least 7 vertical lines in the breadboard. The breadboard is very important for the flashlight.

I had to attach one red and one black wire to a motor. Then I attached the red wire to line 1 and the black wire to line 7 in the breadboard. I had to do the same thing with another red wire and black wire. I connected the other two wires not attached to the motor to an LED light. For the crank, I slid a binding post through a plastic part of the crank. I also slid a rubber ring and rubber cap onto the binding post to make the handle for the crank. To make the flashlight work, I attached the crank to the motor shaft.
I didn't get to make the outside of the flashlight yet. I had to make the circuit work for two LED's. I moved the red wire connected to the LED from line 1 to line 6. Then I connected a resistor to line 3 and line 6. I took my diode and connected it to line 1 and line 3. I had to test the circuit before I added the capacitor. Then I connected the capacitor to line 3 and line 7.
To have two LED's, I removed the black wire from the LED and connected it to a second LED. I also attached a yellow wire to both the LED's. THE CIRUIT IS COMPLETE!! All I had to do was attach the circuit to the flashlight box, close it, and test the flashlight.
In order to have the crank outside the flashlight box, I took off the crank and stuck the motor shaft into the large round hole in the box. The tabs lined up with the small round holes and attached the tabs on the box with brads. To make the crank better, I took a sticky foam circle and attached it to the side of the crank with the handle. I also attached another sticky foam circle, this time with a slit, to the other side. Flipping the box over, I attached the crank back on the motor shaft. Adding two sticky foam strips on the bottom of the breadboard, I flipped the box over and stuck it on the box so the pegs were in the holes above the window.
Right next to where the breadboard is, there were slits for the LED's. I took the LED's from the wires, put them in the slits on the box, and reattached them to the wires. Bringing the bottom panel up, I attached a hook Velcro strap to the top panel and a loop strap to the bottom panel. Folding the top panel inwards, I attached them together and folded the rest of the flaps in. The last thing I did was put a tinker lab sticker on it to keep the handle from hitting the box. THE FLASHLIGHT WAS DONE!!! It's way better than my stemist kit flashlight!
