Arduino’s Zero Hero, Postgresql’s beta and fun small projects

ArduinoZeroArduino Zero: It’s looking like the next Arduino will be the focussed refresh we’ve been waiting for. Makezine has all the details on the Arduino Zero, announced at Makercon. It’s a 48Mhz ARM cored Atmel chip with 256KB flash memory, 32K SRAM and no EEPROM. There’s 12-bit ADCs, PWM on all digital pins, support for an embedded debugger, a second USB port (who knows!) and it’s all 3.3V. Looks super interesting, but the real questions will come when we find out how pricing works out and how hard it’ll be to use recreate the Zero from raw components. See also Arduino’s official announcement.

Postgresql’s new beta: There’s a Postgresql 9.4 beta out there now which doesn’t block when refreshing its neat materialised views, lets background workers be dynaminally registered, started and stopped and more. There’s also more structured support for JSON storage, a logical decoding system for streaming changes out to other systems and an ALTER SYSTEM command which lets you edit postgresql.conf from the SQL command line. One to keep an eye on.

Small projects: First up, a fun little project with a Raspberry Pi, Paho MQTT, Mosquitto, Python and Node-RED is also an excellent example of how easy it is to wire things up with MQTT. Second up, do you want to create a realistic landscape in JavaScript? You could try looking at this landscape generator which makes lovely ground shapes, The article even wraps up with some challenges for coders.
