soft sewing thimbles
330 ohm resistor
10 red led
9 volt battery connector
9 volt battery
black electrical tape
Step 1: Prepare the soft thimbles
Cut holes in the tops of the soft thimbles. Make the holes large enough for the led to poke through, but no too big.
Step 2: Position the LEDs
Place the LEDs into position. With the textured side of the thimble facing you, the positive lead of the LED should be on the right.
Position all the LEDs this way.
Step 3: Attach lead wires
Once all the LEDs have been positioned, it is time to attach the (20) wire leads. The author recycled some white lead wire and placed a piece of black electrical tape on 10 of the wires so as to denote the negative side.
Step 4: Connecting
Once everything has been wired up properly, connect all the positive wires and then do the same to the negative side.
Step 5: Connecting negative side
Connect the negative side of the LEDs/wire configuration to the 330 ohm resistor the connect the other end of the resistor to the black wire of the 9 volt batter connector.
Step 6: Connecting the pushbutton
The push button that the author used had two wire leads coming from it. Connect one side to the red/positive side of the 9 volt battery connector and the other pushbutton lead to the positive side of the LED/wire configuration. Place the thimbles on the ends of each finger and push the button. If everything is wired properly your fingertips should be glowing red.
