Illuminate Your Fingers





Introduction: Illuminate Your Fingers

Now, I will show you a very easy way to illuminate your fingernails and your fingertips.
You can use this beautiful method in many cases.

Step 1: Tools You Will Need

1. A lighter
2. About 50-60cm of wire
3. 5 LEDs (for each hand)
4. Tricot tissues
5. 5 Lithium Batteries (for each hand)
6. Scissors and/or other instruments if you need.

Step 2: Get Ready..

First, use your lighter, scissors, and wires and connect each led light to an about 5-6cm of wire.

Then, connect a new wire to end sides of wires and do it one time for (+) wire and one time for (-) wire.

Step 3: Finalize

stick all of them on your fingers with a temporary material. (see the image)

connect batteries to the wire and then wear your hand with your tricot tissues.

It’s better that one person helps you for this.

You must generate a little pressure (for example with that tissue) on your fingertips in order to illuminate it .

    *wide eyed* wooooooooooooooooooooow

    this is a really cool idea. it would be very useful for working with small tedious things in low light condition. I think if i were to do this i would rig it to a glove for ease of future usage

    Why do you need that much batteries (1 per finger)? there's another instructable that uses 1 batterie for 8 5mm LEDs.

    What an interesting idea. Maybe you could put the LEDs under the fingernails in the manner of the Spanish Inquisition:)

    Actually, you need a bit more instructions. I know it may be simple for you but there may be some folks you have never wired leds or created something battery operated.

    well i think they teach it in school that wont be needed for the next generations

    just like they teach sewing and cooking in school yet most people can't do either? oh, okay.

    Darn, too bad for my generation, then. :/ *looks at un-glowy fingers*

    Alright kiddies, this one is for all those interested in an explanation of how to connect the LEDs to the batteries
    After studying the pictures I believe I have figured out the circuit. And for those who think there should be a resistor, i added that too. Please note that in a project like this, which is temporary, resistors may not even be necessary as the LEDs won't be running for long anyway. In that case, omit the resistors as they will just cause additional bulk. If, however, you want to integrate this into a more permanent solution like a glove or what have you, leave the resistors in.
    The resistor in this circuit is there to prevent too much current from flowing through the LED. LEDs are rated for something between 10ma and 75ma. I'm going to pick an LED rated for 20ma. To find the size for the resistor take the voltage(3V for the lithium button cells) and divide by the desired current (0.02 amps). This gives a value of 150 ohms. A 150 ohm resistor in series with the LED will keep the current at a cool 20ma and keep the LED from frying. The line on the LED corresponds to the flat side of the LED or the short leg. Don't worry about connecting them backwards, nothing will break, it just won't light.
