A favorite memory of mine is from childhood. During bedtime my brothers and I would lie in the dark until sleep came; talking about all the things we'd do once we were older, or about which xmas gifts we wanted or even about girls.
Finger Lights are red LEDs fashioned to the end of soft quilting thimbles that go over the end of each finger. The hopes is that the LED will provide enought light to allow each finger to be seen in the dark so as to allow the user the ability to communicate with someone else while sitting/lieing in the dark. Initially, my idea was to make them recharable utilizing a pull type charging system (similiar to the OLPC pull charger) that gets fashioned into some cool looking wristband. With this current design, I think it is too bulky. Ultimately I would like to use smd LEDs and something less clumsy than the soft qulting thimbles.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
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 + 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. I found some white lead wire that I wanted to recycle. So, I placed a piece of black electrical tape on 10 of the wires so as to denote the - side.
Step 4: Connecting
Once everything has been wired up properly, connect all the + positive wires and then do the same to the - negaitive 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 9v batter connector
Step 6: Connecting the Pushbutton
the pushbutton that I have has two wire leads coming from it, connect one side to the red/positive side of the 9v battery connector and the other pushbutton lead to the + positive side of the LED/wire configuration. That's it. Place the thimbles on the ends of each finger and push the button. If everything is wired properly your finger tips should be glowing red.
