He has a Embedded Systems Programming Blog where you can read and learn programming for the small SBCs and Testing Chips on “USB Stick SBCs” that are now a standard.
Code and Life – Joonas Pihlajamaa
He has useful tutorials on V-USB which is a software-only implementation of a low-speed USB device for ‘s AVR microcontrollers.
He also has many ideas on PC Interface Hardware and Code that may help Home Automation Projects. He reviews embedded starter evaluation boards. Many ideas on Audio and Video using these uC boards.
Arduino Uno and Raspberry Pi to talk to each other
“All that was needed between the two devices was some jumper wire and two 1 kOhm resistors to form a voltage divider between Arduino TX pin and Pi RX pin – Arduino understands Pi’s 3.3V signal levels just fine so Pi TX to Arduino RX needed no voltage shifting at all.”
A fully integrated Test bench based on Virtual Instruments – mixed signal oscilloscope, logic analyzer, spectrum analyzer and waveform generator using BitScope connected via USB or Ethernet to the now very popular Raspberry Pi.
Raspberry Pi BitScope
Regardless of which BitScope you choose, the new BitScope Library is also available making it easy to create your own embedded test, measurement or data acquisition applications using BitScope and Raspberry Pi. Program in C/C++, Python or Pascal using an easy to use programming API.
BitScope Model 10 – World’s Smallest Mixed Signal PC Based USB Oscilloscope!
BitScope Pocket Analyzer. It’s a problem solver that fits in the palm of your hand. Perfect for designing, prototyping and debugging!
It has 100 MHz bandwidth, up to 40 MSps logic, simultaneous waveform and clock generation and offers serial control of connected devices. It’s the ideal tool for prototyping analog electronics projects, digital and logic circuits or Arduino, Raspberry Pi and other microcontroller based systems with busses, sensors, servos and I/O.
Waspmote may have two radios at the same time connected when using the Expansion Radio Board allowing the creation of bridges among different networks such as ZigBee and Wifi, Wifi and 3G/GPRS, RFID and Bluetooth, etc.

Raspberry Pi to Arduino shields connection bridge
“The idea behind the Raspberry Pi to Arduino shields connection bridge is to allow to use any of the shields, boards and modules designed for Arduino in Raspberry Pi. It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry.”
Cooking Hacks – Tasty Electronics for the Arduino and Raspberry Pi Community.
The have a wide range of electronic products and kits including Arduino, ZigBee, GPRS, Sensors, Servos, Leds, LCDs etc.
Here you will find some Raspberry Pi: projects and ideas.DRC or Drogon Remote Control. This is mechanism to allow a device like Arduino connected via serial line to be controlled from a host system.
Raspberry Add Ons from Gordons Projects
You will also find a RTOS called DROSS – The Drogon Real-time Operating System here.
“The Raspberry Ladder is a small kit comprising PCB with LEDs, resistors and switches intended to be used to experiment with the Raspberry Pi’s GPIO functions and hopefully to get people interested in soldering up their own projects. Soldering is not difficult and it’s a good skill to learn if you are keen to learn more about electronics. (or repairing jewelry!)”
