Fresh hacks every day
What has 9000 LEDs, 3000 MSP430 processors, six XMOS XC-2 Ethernet modules, and goes blinkity-blink-blink? It’s Swarm Light, an art installation shown at this year’s Art Basel exhibition. [Fredrik Petrini] worked on the hardware that went into building the group of three 3D cubes of LED light modules. Unlike so many art pieces we see he shared the … Read the rest
[Graham] designed this PIC based Tetris game on a single board. The hardware is quite nice but we enjoyed his explanation of the graphics algorithm that he used. Having coded Tetris from the ground up ourselves we understand how difficult it is to explain how the program works. Tracking pieces already on the board as well as moving pieces, … Read the rest
[Markus] built his own reverse geocache puzzle box but on a smaller scale than the original. His is based around a PIC 18F2520 and powered by two AAA batteries. The user interface includes one button, a 16×2 character LCD, and a piezo speaker. The box unlocks itself when the GPS module inside detects the proper location on the globe. … Read the rest
Nixie Voltmeter Clock
[Gmglickman] built a clock out of an old digital voltmeter. The Fluke 8300A came out in 1969 and is featured in their 60 years of innovation slideshow. What makes it a cool clock? The Voltmeter’s display is made up of Nixie tubes.
