To make this Music LED Light Box you can use many different things and build it different ways. In this instructable I'll explain how I made it, a very simple way. Materials - 12v Adapter (a battery can be used as well) - 3.5 jack headphone cable. - tip31 transistor (this is the key to the whole project) - $0.50 - 5mm LED's (the color or amount is totally up to you, 1 LED per 3v.
I used 12v, so 4 LEDs) - $0.28 - A4 acrylic sheet - 3mm thick (also known as 'plexiglass') - $2.00 - Fine sandpaper (I used 400) - $1.00 - Electrical Wire If you see a price above, that means I bought it. The rest I just ripped of some old junk. Tools - Jigsaw (also a Jeweler Saw can be used. Ones you've got this stuff you're ready to begin! LED Circuitry tutorial: how to hook up LEDs. Light Bar Ambient Lighting. A light bar can brighten your house through the use of ambient lighting. You can lighten up hallways, add a fading glow effect behind your entertainment center, create new patterns in light graffiti or simply add a light source to your house.
There are endless possibilities for lighting with a light bar, it's all up to you! The parts are fairly cheap and the project is fairly easy. You will need to strip wires, solder leds, and be able to use a power drill. Once you have purchased the parts you need (You likely have most of them already) actually putting the bar together should take about 3 hours (if you are inexperienced). This instructable is designed to teach with pictures as well as words. *** I am not liable for any injury, property damage, or any other losses that happen within this project.
Building the circuit. Many people get scared when they see all those weird circuits with those symbols on it. Having no clue what they mean. That's why I made a instructable friendly circuit image :) See photo 1. 1. Make sure you have all the materials to make the circuit. And enough electrical wires to connect all the components. 2. Before we build the circuit, we first need to put the audio cable through the whole in the back. 3. Circuit: The positive pole from the adapter goes to the positive leg of the first LED. For better details please see photo 1, the circuit. 4. If you have trouble getting the circuit to work, you can try to set it up first on a circuit board. RGB Micro-controlled Light Bars. Interested in creating custom patterned LED lighting for your house? Through combining red, green, and blue light at various brightnesses the human brain can be tricked into seeing any color. This technique is used in TVs, the computer screen you are reading this instructable on, phones, and is also used in lasers and set lighting.
This instructable will go through the process of constructing a pre-programmed microcontroller from BigClive.com, and putting together homemade and expandable five-foot light bars, enabling you to have patterned LED lighting. This could range from basic colors of the rainbow (ROYGBIV), through flashing emergency lights to rapid 'rave-style' patterns. This project is highly modifiable for whatever your needs may be (10' light bars, red/white/blue lighting, different wiring styles, etc), and I've created a rather large project out of this involving ten five-foot long light bars.
