Node-RED 0.10.6: Nick O’Leary has announced Node-RED 0.10.6 with various changes to the editor, nodes and API. If you don’t know Node-RED, it’s a rather graphically splendid way of wiring the internet of stuff and stuff in general together – I did a few bits with it on here. With this release, there’s also a new command line administration tool for Node-RED so you can control nodes without having to restart the entire process…. and that uses an Admin API which is now stable and documented. There’s also been a switch in versioning to an easier to track odd/even (development/released) scheme. I’ll be getting back into Node-RED soon myself, ideally when it supports Node 0.12 – currently you’ll need a Node 0.10 to hand to run it.
MOAR PI POWAH: The Raspberry Pi 2 has a lot more power than the older version in terms of CPU, but those USB ports are still pretty power anaemic. By default the total power draw can be 600mA, tweakable in software to 1.2A. That tweakability led to this fine Hackaday hack which involves swapping some components on the board to get a full 2.1A to the USB ports, 500mA a port. The reason the USB is so weedy is good; the Pi is designed to be powered by a Micro-USB connector, so available power is that minus the CPU. Not a lot. And now you have a reason to buy a decent PSU for your Raspberry Pi. The official PSU pushes out 2A into the microUSB.
Arduino IDE gets its groove back: After ages spinning its wheels, the Arduino IDE 1.6 came out and surprised many people. Even more surprising is that its getting new features and quickly. In the March 28th release Arduino IDE 1.6.2, the latest features as a Library Manager which can install from Github repos and a board manager which should make adding new boards much easier. These have been two real pain points in the IDE so to see them addressed is great news. The really great news though was that by April 2nd, the team had released Arduino IDE 1.6.3 which addressed various bugs and responded positively to feedback making it even easier to adopt and use.
ESP8266 adapting: A breadboard adaptor design for an ESP8266 in Makezine since the little ****ers don’t like going into breadboards. Is anyone making these for sale in the UK? Let me know!
Arduino 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.
FreeBSD Journal Edition One: The FreeBSD Journal has published its first digital edition for iPad, Android and Kindle devices. With 6 issues planned for each year, a $20 subscription and an editorial board drawn from the luminaries of the FreeBSD world, it looks like it has everything a FreeBSD fan could want. The first edition, themed around FreeBSD 10, has a five page look at that releases Clang support, ten pages on implementing system control nodes, a white paper on NYI’s use of FreeBSD as part of being an ISP, a six page guide to getting FreeBSD up and running on the BeagleBone Black, an article on ZFS and the future of storage and columns on the news from the ports tree, OS work and a look back on FreeBSD history.
FreeNAS gets an update: FreeNAS, the FreeBSD based NAS operating system, has had an update to 9.2.1, with upgraded SMB/CIFS support bring SMB3 by default, a switch from Avahi to mDNSresponder for better Mac support and around 189 bugs fixed.
Paperduino 2.0: Take a plotter, conductive ink, glossy photo paper and an ATmega328 and print your own Arduino with Paperduino 2.0! The folks behind the Circuit Scribe kickstarter wanted to demonstrate how far you could go with their inks and taking the original Paperduino as inspiration reworked the idea with surface mount components, conductive ink and superglue. Watch the video!
Extra bits: Node-RED and TinyTX boards being used for home monitoring. Gitbucket is a Github clone written in Scala with JGit underneath. Want FreeBSD on OpenStack? Check out bsd-cloudinit then.
