We've seen Emotiv's Epoc headset control cars and trapeze acts, but now a small posse of students at Columbia University is teaching it how to control a robotic arm. The appendage, aptly named ARM for Assistive Robotic Manipulator, was envisioned as a wheelchair attachment to help the disabled. According to the team, the goal was to keep costs in the neighborhood of $5,000 since insurance outfits Medicare and Medicaid won't foot a bill for assistive tech that's much more than $10,000. To keep costs low, the crew built the limb from laser cut wood, and managed to keep the final price tag at $3,200. Since picking up EEG signals and interpreting them accurately can be tricky, the group says it settled on monitoring EMG waves, which are triggered by muscle movements, for additional reliability.

Lifting your eyebrows makes the device open its grip, clenching your teeth shuts it and moving your lips to the left and right twists the claw, while other motions are currently handled by using a PlayStation 2 controller. In the lab, the contraption has seven degrees of freedom, but it was reduced to five when we took it for a spin. It was hit or miss when this editor put the headgear on, between making sure facial gestures were spot on and the equipment's attempts to pick up clear signals.

Spark Devices wants the inclusion of WiFi in devices to be a matter of when, not if -- and if its new Spark Core gets to market as planned, tinkerers might never have a moment of doubt. The tiny board combines an Arduino-compatible ARM Cortex-M3 platform with a TI CC3000 WiFi chip that not only simplifies getting online, but could save the DIY crowd from having to touch projects afterward. Owners can flash the firmware with new code over WiFi, for a start. A free Spark Cloud service also allows for custom apps that interface with the Core through seemingly anything with an internet connection: if you want to reconfigure a homebrew security camera from your phone, you can. While Spark Devices is relying on crowdfunding to fuel its connected strategy, the company is comfortably past its $10,000 goal and should deliver both the Spark Core ($39) and optional shields to new contributors around September.

As glad as we are that MediaTek ushered in affordable, quad-core SoC designs with the MT6589, even that silicon can only go so far in making smartphones accessible. The company's new MT6572 might be frugal enough to lower some of those few remaining barriers. The all-in-one part mates a cheaper dual-core, 1.2GHz ARM Cortex-A7 processor with HSPA+ 3G, China-focused TD-SCDMA, Bluetooth, GPS and WiFi, dropping the construction costs beyond what even the chip's quad-core sibling can manage. While the MT6572 can only handle up to a qHD display, a 5-megapixel camera and 720p video, that's more than enough to improve baseline features in a category where many recent entry-level phones still tout single-core CPUs and WVGA screens. Its rapid arrival in the marketplace may be crucial, too. MediaTek expects the first phones based on the MT6572 to roll out in June -- just in time to keep the world's transition to smartphones moving at full steam.

Linus Torvalds has pulled the big red lever marked Version 3.9, unleashing the latest Linux kernel onto the world and at the same time bringing some good news for Chromebook tinkerers. The update builds on the Chromebook Pixel tweak we saw back in February by adding support for components in "Chrome laptops sold by many companies" -- with the changelog specifically mentioning the x86-powered Samsung Series 5, Acer C7, HP Pavilion 14 as well as support for the Pixel's touchscreen, all of which should make it easier to run your preferred distro in place of Chrome OS on those machines. Other general improvements include better support for Intel power-saving features, the ability to use an SSD as a hard drive cache as well as KVM visualization for users with ARM-powered gear. Just make sure there's no NVIDIA hardware inside any of those boxes -- you know it makes Linus cranky.

Although we've seen a deluge of tinker-friendly boards, many of them share a dirty secret: they're borrowing someone else's OS. The creator of the new CoAction Hero board, Tyler Gilbert, doesn't think that's good enough for those who want both control and ease of use. His stackable ARM Cortex-M3 design runs its own real-time platform, CoActionOS, that supports Raspberry Pi-style features like file systems and multitasking while abstracting the hardware enough to remove some of the usual headaches. Coding for the CoAction Hero is much like writing a desktop app, and a Qt-based developer kit helps owners write their own interface without knowing the circuitry inside-out. The board is being crowdfunded and won't ship until July if all goes according to plan, but a relatively low $10,000 target and $29 minimum pledge for a device should get the Hero into the hands of intrepid project builders.

ARM has had a great quarter -- again. This time it's seen pre-tax profits soar 44 percent, while revenues are up 26 percent (to $209.4 million) since the same period last year. The company's thanking the continued adoption of its low-power chip designs, encompassing smartphones, mobile computing and even digital TVs and wearable tech. The advanced tech within its ARMv8, Mali and big.LITTLE ranges has meant the company can command higher royalties per chip.

In total, 2.6 billion ARM-based chips have made their way into the gadgets this quarter, an increase of 35 percent year-on-year, with embedded hardware up a hefty 50 percent since Q1 2012. It's seen even better performance from its Mali graphics processor shipments, which are up five times since the same period last year. As outgoing CEO Warren East notes: "Even low cost smart devices can contain multiple ARM-based chips and be based on ARM's advanced Cortex-A series technology and Mali graphics processors." With new friends on board for the near-future, the good times are likely to continue.
