It’s time for our weekly wrap up of Elektor news and content for Circuit Cellar members. As usual, our colleagues in Europe and beyond are always covering some cool embedded-related topics.
Let’s start with an interesting post about an innovative processor-based healthcare system: an intelligent patch capable of continuously monitoring heart activity. The design combines embedded and wireless technologies to measure, record, and transmit electrocardiogram signals:
The patch developed by the research labs Imec and Holst Centre and the Danish company Delta measures 3 ECG signals while a 3D accelerometer monitors physical activity. The captured data is processed by a microprocessor integrated in the patch and relevant information is transmitted wirelessly using the new Bluetooth Low Energy technology. Energy consumption is low enough to allow continuous operation during one week.

Have you been reading Circuit Cellar columnist Bob Japenga’s articles on embedded Linux? If so, you’ll check out Elektor’s post about Raspberry Pi:
The board is based on a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, a VideoCore IV GPU and 128 or 256 MB of RAM is intended to run Linux kernel based operating systems. Selling for only 28 Euros the distributors’ websites have been overwhelmed by the demand and the first batch of 10,000 pieces was sold out in less than an hour.
The foundation plans to release two versions: Model A & Model B. Model A will have 128 MB RAM, one USB port and no Ethernet controller, while model B will contain 256 MB RAM, two USB ports and a 10/100 Ethernet controller.
Lastly, consider attending the upcoming Elektor Academy webinar “AVR Software Defined Radio.” The webinar is scheduled for 3/29/12. Click here for more information. If you attend, be sure to let us know what you think!
