Insert Coin: Modkit Micro asks us if we're ready for six-year-olds coding Arduino boards
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. What does microcontroller programming have in common with Tetris? Quite a bit if you're doing it with Modkit Micro from a Kickstarter project out of Cambridge, MA., which allows almost anyone to visually set up their hardware using graphical blocks to write the code. The partially-hooded trio behind it promises that the software is ideal for use with prototyping boards from Arduino, Evil Mad Science, Lilypad, Seeed Studio, Wiring and SparkFun, and they even claim that elementary school students have used it to "take their projects from concept to reality in just a few hours." Purists should have no fear either: you can still get into a code view to see what's going on behind the scenes. A web-based Modkit Micro is being offered online starting June 1st for $25, and there'll be a desktop variant for Windows, OSX, and Linux as early as July if they reach their funding target. Check out the video after the break and then try to get your kids to wait for college before inventing version 2.0 of this.
Panasonic preps samples of next-gen ReRAM devices, NAND preps for early retirement
The Galaxy S III may rock an impressive battery life, but if Panasonic has its way, even greater benchmarks could be on the horizon. The company is ready to start making samples of a new ReRAM microcontroller, and -- like Sharp and Elpida -- it could start mass production as soon as next year. Here's a little refresher: ReRAM is a new kind of memory with re-write speeds far superior to NAND because it doesn't need power to hold onto information. Panny's chip will initially be used in simple devices like fire alarms, but the tech could eventually find its way into our TVs and even smartphones and tablets. But seriously, are we even capable of living in a NAND-free world?
KegDroid dispenses beer with the help of a Xoom tablet and an Arduino board
Here's an instance of NFC technology that's more exciting than yet another tap-to-pay scenario. Google employee Paul Carff combined a Motorola Xoom running ICS with an Arduino microcontroller to create KegDroid, a friendly green beer dispenser. The Xoom acts as a gatekeeper to that brewed goodness, only letting the bot dispense drinks after users swipe an authorized badge. The badge is read by an NFC scanner on the bottom of the case and is then authenticated (or rejected) by the Arduino board. Once the system grants access, users can choose from two selections on tap via a custom Android application displayed on the Xoom's screen. As Android Community points out -- and as you'll see in the video below -- the KegDroid hasn't mastered a bartender-level pour (read: there's way too much foam). Still, this is oodles cooler than your average keg, wouldn't you agree?
Valve employee spills the hardware beans: wearable computers, ahoy
When Michael Abrash started working for Valve, he expected the higher-ups to hand him a pile of work and tell him to hop to it. They didn't. Instead, he was told to figure out the most valuable thing he could do for the company, and then do it. So, Abrash wound up kicking off an in-house R&D project for wearable computers, and according to a recent blog post, is looking to expand his research team. More than me-too mice and gamepads, indeed. Abrash is quick to put a lid on rumors of "Steam glasses," however, and warns readers not to expect any big reveals at E3 -- this is just an "initial investigation into a very interesting and promising space," he says, and is more "research than development." Rearing to give Google's Project Glass a run for its money? Or maybe you're just itching for a detailed narrative of employee and employer? Either way, you'll find what you're looking at the source link below.
Valve job posting reveals plans for homegrown hardware, promises it won't suck
Rumors fluttering about Valve's entry into the hardware market just got a little less salty. According to the outfit's own jobs page, it's prepping to offer consumers "whole new gaming experiences." A call for an experienced electronics engineer says it all, "For years Valve has been all about writing software that provides great gameplay experiences. Now we're developing hardware to enhance those experiences." The ideal candidate ought to have a hefty load of prototyping experience, a knack for working with embedded systems and microcontrollers, a proficiency in thermal management, high speed serial interfaces, ARM / x86 system design, and more. We're not about to hazard a guess at what this adds up to, but Valve promises it's more compelling than "me-too mice and gamepads." Hit the source link below to apply, get hired, and let us know what's up.[Thanks, Alexis]
Tacit sonar gauntlet gives the blind ultrasonic eyes (video)
Sure, your Arduino project can make a stuffed monkey dance, but is it really doing anything for the greater benefit of mankind? Okay, maybe -- but not to the same degree as Grathio Labs' Tacit glove, an Arduino powered sonar device that can help the vision impaired navigate foreign environments. This wrist-mounted gauntlet is comprised of an Arduino microcontroller, a few ultrasonic sensors, and a pair of servomotors to apply variable pressure to the user's wrist to indicate their distance from an object or obstacle. Best of all, the gizmo's circuit and software are registered under Creative Commons, which means you're free to snag the plans from the source link below, and build your own. Go on, build one. Sure, it's a lot of work, but would you rather rock a wrist-mounted sonar gun, or don an ear-tugging bicycle helmet? Your choice.
The multimeter clock doesn't fail to electrify us
This is the multimeter clock. It's made of three actual multimeters -- one each to display the hour, minutes and seconds with a 16F628A PIC microcontroller to do the actual timekeeping. Do we want one hanging in our living room? Not really: but it's still very cool.
