Axiomtek has unveiled the CEM700, its first COM Express Type 7 module with 5th Gen Intel Xeon or Pentium CPUs, 2x 10GBASE-KR, 2x SATA III, a lot of PCIe, extended temperature support, and a... Read more
The Internet of Things (IoT) is creating many new exciting application opportunities to create smart environments where sensors monitor for changes so that the appropriate actions can be tak... Read more
The RPC is a MIDI controller and implements the age-old 1980s serial MIDI bus, and the Protosynth must be capable of interfacing with it. But in general use a USB device port is much more pr... Read more
The Raspberry Pi computer is eminently suitable for interfacing. It has 17 GPIO lines which can be programmed to be either inputs or outputs as well as various other functions. They are very... Read more
Solution Connect an LED (see “Opto-Electronics”) to one of the GPIO pins using a 470Ω or 1kΩ series resistor (see “Resistors and Capacitors”) to limit the current. To make this recipe, you w... Read more
In the previous article Raspberry Pi – Installing a RS232 Serial Port we discussed how to install a RS232 port on the Raspberry Pi. This is a follow up article to suggest a few altern... Read more
TESTS (1) On the Quick2Wire boards there is a 3-pin male header with pins for 5V, 3.3V, GND. I attached the test circuit to 5V and GND — it glowed as it should. Same for 3.3V and GND. So I d... Read more
Note: Full source (still not finished) is available github.com/drcrane/raspberryrfid. The Raspberry Pi has a few different interfaces available to it, one is I2C (a protocol created by Phili... Read more
Geiger counters are basically just devices which enable us to measure ionizing radiation. In the context of human activity we have to deal with natural radiation sources and artificial ones.... Read more
Global Unichip, TSMC’s design arm, is manufacturing a consumer electronic applications processor ASIC with a DDR2/3 interface delivering 2.0GHz Mbps from its 40nm low power (LP) process. Key... Read more
