The Neurophone is an invention that allows you to transfer sound directly into the brain using either radio signals, or ultrasound. A DIY version of the latter was developed by Andreas using a simple PWM modulator IC TL494 and piezoelectric speakers. The second version of the “Neurophone” used ultrasound instead. By modulating an ultrasonic signal […]

Pipistrello: Spartan 6 development board with 64MB of RAM, High Speed USB, and HDMI
Magnusk designed the Pipistello Spartan 6 development board with the same IO headers as the Papilio One. It features 64MB of RAM running at 200Mhz, the FDTI FT2232H High Speed USB IC, HDMI output, and a micro-SD card holder. So the only option left was to make my own board – basically merging the FPGA […]
Workshop Update for August 8th, 2012
Today we are flying back to the workshop from our Singapore Global Geek Tour. Expect a full report soon. We successfully added an SPI EEPROM emulator to our Bus Pirate Demo Board v5 firmware. We also had time to finish the SPI PWM generator, and the SPI DAC emulator. We added the 74×573 octal latch […]
Part Ninja v1c free PCB build
Ginpb built a free Part Ninja v1 PCB. The Part Ninja is a electronic component testing tool. It identifies electronic components like transistors and FETs, determines the pinout, and measures basic specifications. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you […]
Global Geek Tour Singapore: Food
The food in Singapore was amazing. Here is a collection of food related pictures we took on the Singapore Global Geek Tour. First up, our favorite Japanese beef bowl (Guydon) place Yoshinoya has a location in Bugis junction!
HOW-TO: Eagle Keepout and Restrict layers
Keepout, and restrict polygons are powerful tools at your disposal as a PCB designer. Keepout is used when you don’t want components placed within an area, like edges of a board, or where your heatsink will be placed. Restrict polygons make sure the specific copper layer cant be placed within the polygon. We use them […]
A13-OLinuXino first time Android boot
Olimex is hard at work to roll out the A13 based OLinuXino by September. In the latest news they were able to flash the device with a custom Android build. Dimitar Gamishev learned that we have A13-OLinuXino prototypes and came to our office after work, he already had pre-built Android image, so after spending some […]
AVR based intelligent temperature monitoring and control system
Shawon designed, and built an AVR based intelligent temperature monitoring and control system. He documented both the hardware, and the firmware on his blog, with in depth descriptions on how everything works. Controlling temperature has been a prime objective in various applications including refrigerators, air conditioners, air coolers, heaters, industrial temperature conditioning and so on. Temperature […]
