  GelSight, a new 3D surface sensing material can be used to visualize and measure surfaces. Zedomax member reports that GelSight is a pretty top-notch stuff that can detail at even microscopic levels. “The optical property of the material is making it very complicated to see the surface structure”, said Johnson, co-founder of GelSight, Inc. For more information, you can read the paper presented at SIGGRAPH 2011 named: “Microgeometry Capture using

Hackedgadgets member Alan Parekh shared a great work carried out by Edo at Hamburg University, Germany. He build a real cool color LED table comprising of 64 sections of RGB LED’s arranged in a matrix of 8X8. The table is controlled by Arduino Duemilanove microcontroller. “Materials used: 1 Arduino Duemilinove microcontroller, 12 Texas Instruments TLC5940 16-channel LED drivers 64 numbers of 5mm RGB LED Table dimensions : 50×50×12 centimeters Cladding
