Code and Life - Joonas Pihlajamaa

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.

Arduino Uno and Raspberry Pi to talk to each other

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."

DRS4 Evaluation Board - Paul Scherrer Institut

Ever wanted to develop a Professional High Speed DAQ or a Storage Oscilloscope or even a High Speed Communications grade Logic Analyzer. Here is a front end Analog Mixed Chip with Eval Board.

You could make a High Speed Test Instrument and probably build a Android tablet front end. How would a 200 M Hz Oscilloscope look on you 10 inch tablet. You will float in the clouds.

The DRS chip is a full custom Integrated Circuit developed at PSI, Switzerland. It contains a switched capacitor array (SCA) with 1024 cells, capable of digitizing eight analog signals with high speed (6 GSPS) and high accuracy (11.5 bit SNR) on a single chip.

By using channel cascading, we can configure this board with 2048 bins for each channel at the expense of a lower analog bandwidth of about 500 MHz. The on-board comparators enables the board to do a self-triggering on a programmed level of any of the input channels or logical combination of channels, much like an oscilloscope.

Highlights of Board with One DRS4 chip
  • Four 50-Ohm terminated input channels with SMA connectors
  • Active input buffers which result in an analog bandwidth of 700 MHz (-3dB).
  • One AD9245 ADC to digitize signals from the DRS4 chip
  • One Xilinx Spartan 3 FPGA for readout control
  • A 16-bit DAC to generate all on-board control voltages
  • A serial EEPROM containing serial number and calibration information
  • Internal trigger with user-defined thresholds on any of the four channes.

Meshlium is the world's only multiprotocol mesh router to combine Wifi, ZigBee, GPRS, Bluetooth and GPS technologies

Meshlium modular and configurable Router - Libelium

Meshlium receives sensor data from Waspmote Plug & Sense! and forwards it directly to the Internet via Ethernet, Wi-Fi or 3G/GPRS protocols depending on the connectivity options available in the area.

Meshlium modular and configurable Router - Libelium

Meshlium is a Linux router which works as the Gateway of the Waspmote Sensor Networks. It can contain 6 different radio interfaces: WiFi 2.4GHz, WiFi 5GHz, 3G/GPRS, Bluetooth, XBee and LoRa. As well as this Meshlium can also integrate a GPS module for mobile and vehicular applications and be solar and battery powered. These features along with an aluminium IP65 enclosure allows Meshlium to be placed anywhere outdoor.

MightyOhm - Join the Resistance

Jeff Keyzer, aka mightyohm. Amateur Radio and DIY Electronics Projects are there with this High Wattage Resistor. posts about microcontrollers (mostly PIC and AVR), Arduino, embedded Linux, circuits, DIY projects, and other related stuff. 

MightyOhm - Join the Resistance

Includes PCB with pre-assembled DC-DC converter, all components required to build the kit

AVR HV Rescue Shield Kit 2 - mightyohm.com

The AVR HV Rescue Shield is a high voltage parallel mode fuse programmer for Atmel AVR microcontrollers. It currently supports the ATmega48/88/168/328P series and the ATtiny2313.

AVR HV Rescue Shield Kit 2 - mightyohm.com

Some Features:
  • Version 2.1 introduces a new and improved 12V switching circuit
  • Completely open source. Source code, schematics, layout, BOM are available.
  • Onboard 12V DC-DC boost converter eliminates the need for an external 12V power supply.
  • Support for programming the extended fuse (EFUSE) byte.
  • An interactive mode, where desired fuses can be entered using the Arduino’s serial port.
  • Separate Ready and Burn indicators.
