This is how my Indoor Night Umbrella works (reference diagram if necessary):  the negative terminal of the battery is connected to one of the stretches, which is linked to the rib where I have attached the negative leg of the LED.  In essence, the negative terminal of the 9v battery, which I used to power…

My project consists of a row of L.E.D.’s on a chip board on my knuckles that light up when i make a fist. The L.E.D.’s are set up in a parallel circuit to ensure that each light receives enough power. The way it lights up is through connecting the two negative wires to complete the…

I created a cup on which LEDs light up on the side corresponding to the liquid level inside the cup using a floating magnetic assembly and a series of reed switches.

The Evil Pig stuffed animal uses brass snaps on its feet to complete the circuit to light the LEDs. The LEDs are connected in series to each other with a resistor and are powered by a 9-volt battery that rests in the belly of the pig. The negative lead to the battery is connected to…

When I first started on this project I wanted to do something with coffee cups. I realized that I have a habit of twisting my cap when I drink my coffee. With this I made a project that when I twist the cap in a certain position, it lights up the two LEDs at the…

To make the earrings light up, you will need: – LED x6 – 3V Lithium battery x4 – earrings x2 – copper tape – beanie or hat – isolating tape – needle  – thread – Soldering Iron – Needle nose pliers Light the LED earrings by wearing the beanie. The batteries are sewed in the two inner side of the…

My idea for the Creative Switch project is a little town enclosed inside a kitchen container dish with a lid. I have called it LED LAND. Materials        kitchen container dish        one diode        two 560 ohm resistors         47 ohm resistor        relay       7 total LEDs…

The idea behind my creative switch was influenced by my habit off misplacing the different kinds of cards I have in my wallet at all times (i.e. iCard, Credit/Debit Cards, License). So I decided to creative a circuit to act as a reminder that the card is not in my possession at the time or…
