Making Catchup: Node 0.10.6, Pi Power, Arduino IDE and adapting ESP8266s

makingcatchupNode-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!

Raspberry Pi2 – Already?

Pi2ModB1GB_-compIt seems like less than a year ago when Eben Upton told Ars Technica that the Raspberry Pi Foundation was “a year or two away from thinking about” building new hardware. In less than a year, we’ve had the Model B+, the Model A+ and now, as a “Well-actually-we’ve-been-thinking-about-it-lots”, here’s the Raspberry Pi 2.

The good? It’s a quad core 900Mhz A7 ARM chip, it’s got 1GB of RAM and it looks just like a Raspberry Pi B+. The better? It sells for £30, same price point as the B+. The neat? The upgrade to A7 means that more ARM software runs on it… Ubuntu Snappy Core is available and, run for the hills, Windows 10 for Devices is coming.

The not so good? Well, it’s not good news for anyone who just bought a B+. Ta-da launches and an air of mystery don’t really sit well with a charity, which is what the Pi Foundation is. It doesn’t help educators make best use of their funds in their planning.

But anyway, it’s a new Raspberry Pi and its definately an improvement. I’ve gone and ordered a bunch myself so I’ll be reporting back as soon as possible on how it feels.
