A SNAFU box project by Bertho of Vagrearg: SNAFU Box consists of 24 LED strips (12V passive type) of varying size, which are controlled by a set of 74HC595 shift-registers and a transistor driver for each strip and RGB channel. The LED strips are used to backlight the lettering of the box. An additional three 74HC595 […]
Limpkin writes, “I’ve always wanted to play with these 10W RGB LEDs! So for some reason I bought 2 IKEA lamps at a flea market. As IKEA furniture has a long history of being hacker-friendly, I figured they shouldn’t be an exception to the rule. My plan? Fit a few 10W RGB LEDs in there […]
Dmitry Grinberg writes, “Lighting a room is always a complicated task. This is especially true if you’re an engineer. You see, we all love blinking lights, RGB LEDs, really any combination of those things. When it came time to figure out the ligting situation for my room, I immediately knew that lots of LEDs would […]
Marcus Jenkins writes, “I made this gadget which steps up the game from leaving a light on at home when you’re out. Place in near a window to make it look like somebody’s at home watching TV. ” Project details at Marcus Jenkins’ site. Via the contact form.
Drew tested out some addressable RGB LEDs he bought during Hacker Camp, using a Bus Pirate. Via Shenzhen_hacker_hole WeChat group. The LDP6803 uses SPI for communication. A power supply and a Bus Pirate and I was able to change colors without code. The chip uses a 7bit encoding of colors so setting individual colors can’t […]
Tom Van den Bon and Sebastian Schocke of Binary Space, a makerspace in the Vaal Triangle, have put together this build challenge for their members. For December at Binary Space we wanted to do something a cheerful and colourful. We got together to design and build a low power LED table or ceiling lamp that […]
cpldcpu writes: What’s pretty cool about these LEDs is that they are diffuse – no more blinding unidirectional light. This might be very useful for indicator lights. Furthermore, you can easily wire them freeform without a pcb. I see a lot of RGB LED cubes coming up… The LEDs come with four leads: VCC, GND, […]
Here is a light show project from North Street Labs built for the Hippodrome. They built 7 large LED panels that are controlled trough an RS-485 link. Each panel has 86 RGB LEDs and an Arduio controlling them. The build is well documented if you want to try this at home. Via Hacked Gadgets.
Adrianmb from Make-a-tronik has written a tutorial on how to how to communicate between your mobile device (Android / iOS device) or a PC and Arduino through a protocol known as OSC (Open Sound Control). The project uses Processing, Arduino, and an LED RGB device. TouchOSC must be installed on the computer or iDevice you […]
Atarity writes to inform us of a project being developed in Russia known as the Lightpack 5.5, with an English language wiki page available. The software analyzes the image on your monitor and transfers its data by USB to the Lightpack board. This board lights the surface behind a monitor, TV or laptop by means […]
This LED flower is controlled by AVR with software USB stack. It contains 6 RGB LEDs which are at the end of twisted enamelled copper wires. Project is well documented with extensive tutorial. Via mcu.cz
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few professionally-made PCBs from one of our past or future projects, or a related prototype. This is a USB controlled RGB color changing light. Someone made some minor modifications to […]
