Hobby Tech this month covers the launch of the Sugru Rebel Tech Kit, the performance improvements made possible in the latest Arduino IDE, and ends with bad news for Arduino.cc’s new Genuino brand which, I’m pleased to say, has since been replaced by significantly better news.
Sugru, for those not familiar, is remarkable stuff. Straight from the packet it has the consistency of well-worked Blu-tack, if not slightly softer, but with nothing more than time hardens into a firm silicone rubber. It’s waterproof, heatproof, electrically insulative, and I’ve used it in the past for everything from mounting a tablet to the side of my monitor to customising the scales on a Leatherman multitool.
The Rebel Tech Kit, then, is Sugru’s attempt to grab some Christmas gift traffic. Featuring four sachets of Sugru, a guitar pick for moulding and removal, a storage tin, and a full-colour project booklet, there’s not much in there for those already experienced in the ways of “mouldable glue.” For newcomers, though, it’s a fantastic introduction, and one I can see appearing under trees around the world.
The Arduino IDE tests, meanwhile, were fun to carry out. Updates to the AVR Core – the toolchain used for ATmega-based microcontroller boards like the Arduino Uno and Arduino Mega – have brought with them the promise of smaller binary sizes and improved performance, which was an excuse to pull out my microcontroller benchmark family: the floating-point Whetstone, integer Dhrystone, and my own pin-toggling IOBench. The result is an in-depth look at the improvements you can expect from upgrading, complete with pretty graphs and even prettier screenshots.
Finally, the Genuino’s death knell. At the time of writing, noted Sheffield-based hobbyist supply house Pimoroni had revealed the outcome of months of negotiations with Arduino.cc: they would no longer stock the company’s boards. The reason: the ongoing legal battle with Arduino.org over international trademark rights, which had seen Arduino.cc launch the Genuino brand. A refusal to sell Genuino-branded hardware to resellers that would make them available in the US was causing headaches that Pimoroni could do without, which were detailed in the company’s blog post and expanded upon in the final page of my column this month.
Publishing, though, has considerable lead times, and in the time it’s taken this issue to hit shop shelves there’s been a welcome development: Arduino.cc and Arduino.org have merged, ending all legal proceedings between the two and meaning that the problems experienced by Pimoroni over trademark rights and product geo-fencing should no longer be an issue. The impact of this merger, and what it means for the Arduino user, will be explored in a future column.
All this, plus a bunch of interesting stuff from people other than myself, can be found at your nearest newsagent, supermarket, or digitally on Zinio and other distribution platforms.
