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 new Type 7 carrier board. The CEM700 offers processor options from the 16-core Intel Xeon D-1577 and quad-core Pentium D1519 processors from Intel’s 5th Generation …

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 taken. The fastest growing examples of this are HVAC (Heating Ventilation and Air Conditioning), IAQ (Indoor Air Quality), smart homes and smart offices where a network of sensors monitors temperature and …

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 practical than the three ubiquitous MIDI ports; it allows connecting the synth directly to a laptop or other computer at …
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 low power lines however, and on their own can only drive tiny LEDs. With this in mind, I have designed the interface on …
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 will need: Breadboard and jumper wires (see “Prototyping Equipment”) 1kΩ resistor (see “Resistors and Capacitors”) LED (see “Opto-Electronics”) Figure shows how you can wire …
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 alternative interface options as the XBit RS232 level-shifter board has been unavailable (sold out) for while now. There are two primary …

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 decided that the board was probably working. (2) I left the black lead of the …

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 Philips and used in many places, it is the basis of VESA DDC!). I had the opportunity recently to interface with an SL030 RFID Mifare reader, it is …
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. Some of the materials emitting ionizing radiation are used to create electricity, others were used to stockpile thermonuclear bombs, so many could get scared and …
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 steps were designing to the performance sweet spot of GUC’s DDR2/3 high speed interface IP, a condensed package substrate, and a PCB through a precise DDR system …
