Introduction When Adafruit announced their capacitive touchscreen shield, I knew I had to do something cool with it. I mocked up a design for the Château using an Atmega32u4, but once I saw this post on Hackaday, I quickly changed to the Teensy 3.1. Being able to update the display at a reasonable rate makes […]

I have built a little FPGA board Xilinx xc3s250e called WireFrame. the board is only 50mm x 25 mm in size and it is possible to breadboard it. board also has 32MByte SDRAM, 4MByte serial Flash for storage. total 3  2A max  each Switching regulator for Vcc I/O 3.3V (adjustable with regulator feed back resistors), […]

A nifty 32×7 dot matrix display module, programmable via an RS232 serial port. There are preset inputs to display preset messages or simply control directly from a PC or laptop. DESCRIPTION The principle of the display is based on our persistance of vision, the same thing that enables us to watch movies without seeing the […]

An archaeological expedition from the Institute of Archaeology of the Russian Academy of Sciences, while conducting a rescue excavation dig near Zvenigorod (Moscow Region) involving the new Central Circular Highway, has unearthed the private arsenal of a military commander from the era of Ivan the Terrible.

KORG INC and Noritake Co., Limited are proud to announce the successful development of the ground breaking technology, Nutube, a new miniaturized and high performance tube. In cooperation with Noritake Itron Corporation, KORG INC. has developed the Nutube to offer incredible reliability and efficiency while still generating the same rich harmonics which vacuum tubes are […]

Let’s get the good stuff out of the way above the fold. Raspberry Pi 2 is now on sale for $35 (the same price as the existing Model B+), featuring: A 900MHz quad-core ARM Cortex-A7 CPU (~6x performance) 1GB LPDDR2 SDRAM (2x memory) Complete compatibility with Raspberry Pi 1 Because it has an ARMv7 processor, […]

In Florida carpenter ant colonies, distinct worker castes called minors and majors exhibit pronounced differences in social behavior throughout their lives. In a new study published today in Science, a multi-institution team anchored at University of Pennsylvania found that these caste-specific behaviors are not set in stone.

TMPM470FDFG and TMPM475FDFG enable dual control of two brushless DC motors Toshiba Electronics Europe has announced two new products to join their range of ARM® Cortex®-M4F based TX04 series microcontrollers. Both the TMPM470FDFG and TMPM475FDFG are capable of operating two brushless DC motors simultaneously. The new microcontrollers aim to satisfy ever-increasing demand for more energy […]
