#BeagleSNES  is my port of the SNES9X Super Nintendo emulator to the BeagleBoard-xM and BeagleBone Black ARM SBCs.  My goal is to turn these boards into a stand-alone appliance/console, so there is quite a bit more to it than just the emulator itself.  While the RPi has its share of emulators, the extra processing power of the BBB target really brings some of the old SNES games to life in a way that the RPi can't manage.  

I've been developing this software for over a year now, and the latest version has added in GPIO input support on the BBB target so that you can use the BeagleSNES to develop your own handheld game consoles or custom controllers. The prebuilt images of BeagleSNES are 4GB images that can be copied onto a microSD card.  Flash the prebuilt image to the microSD and you're ready to get started.  Source code for the bootloader, kernel, and emulator/GUI are all available for download, and there is also a (pretty detailed) manual that describes how to set the system up and how all the parts and pieces of it work.

Get a color-changing (rgb) for added fun. And less stereotyping! It is a cute and cleanly done project though.

New Product: Hurt Locker (Defusable Bomb) Kit  Time to be a hero! 

As one of the DFRobot classics, the Hurt Locker Kit allows you to make a scary looking time bomb that you can actually "defuse" with wisdom and courage. It is based on Arduino and is very fun to play, especially in festivals and gatherings. 

After assembly, press the start button and then you will see two colors flicker in sequence. Do not forget them and quickly look up the third color with the color sheet in your hand. Remember you've got only 15s! There are 6 colored wires across the top of the bomb and you have two attempts to get rid of the correct wire. If you fail, things will end up in a loud blow (balloon).

No soldering is required with this kit, our intuitive user manual will guide you effortlessly with assembly. Only few minutes and you are ready to take the challenge!

OK Makers, we tried this before and got some great responses from you.  Lets try this again.
 
Lets see how many correct answers we can get to this question: What are some examples of applications that use left-handed threads?  In other words...where does "lefty-loosey, righty-tighty" NOT apply?

Some older British cars has left hand threads on various parts of the car, for example I had a 64 Triumph Spitfire having some.

I'm working on a game called Contraption Maker. It's a game that lets you make ridiculous Rube Goldberg type chain reactions. Our community has made all sorts of awesome things like ball sorters and 8-bit counters.

This game is a spiritual successor to an old PC game called The Incredible Machine, and it's being made by the same guys.

The game is currently available on Steam http://store.steampowered.com/app/241240

This looks like fun!!
Key West’s Minimal Regatta:
Each team to build a boat out of a four-by-eight sheet of plywood, two eight-foot-long two-by fours, a roll of duct tape, A POUND OF #FASTENERS and epoxy paint.
Does your city do anything similar?

Hackerlings

Fun & Games  - 
 
 
Made this for +Hackerlings's workshop at Mountain View Library Star Wars Day.  It greets you with Star Wars theme song as you sit down.  With a swipe of hand, you can command an R2D2 chatter to get a clean start.  When  you leave (desert the station), it sends you off with Imperial March.

Lessons learned?  The basic function is based on my earlier gum box prototype (https://plus.google.com/102345534186126041144/posts/BDywAevZRNw), also built for +Hackerlings.  In that, I learned that the mouse was a differential device, not a positional one.  For this, I want a "boxed up" screen.  The design goal is to have all parts exposed and show how simple the circuit is. (No even a breadboard is needed.)

You don't want to "shake clean" such a giant box.  So what could I use to start over?  Such is the question to brainstorm with my 9-year-old.  After pruning out choices obvious but mundane (buttons, anyone?), and those adventurous but which I couldn't make in short order (mind-control - yeah, right).  We narrowed down on a few natural movements people make to "clean up" a drawing.  "Air swipe" is pretty close to eraser action and, as my little coconspirator points out, fits well into Star Wars theme as it "makes people feel that they are using 'the Force'."  And I can readily simulate it with a range finder which I had learned in my Hand-O-Organ project (https://plus.google.com/102345534186126041144/posts/aVezzxA874f).  I only need to detect edges to have a good-enough illusion of swipe detection.  For time's sake (it was two nights before showtime), I had to settle with a quick-n-dirty 2-cycle stabilization by declaring a rising edge ineligible if the previous cycle was in close range.  Given my SR-HC04's 182-ms open duration, the result is a somewhat zen-like feedback loop: you must not be too slow, but you cannot be too quick, either.  Children actually find this jerky experience very Jeidiish, for it forces the user to practice.

An added advantage of using range finder for "swipe sensor" is that the same sensor can be used for actuation-deactivation.  Reducing false positive took me even longer than programming for hand gesture.  A rolling average was my initial choice, but I resolved not to use an array. (A reasonable "seating" assumption would be > 2 seconds.  Array will eat up too much of memory.)  I found some 2-variable algorithm on the Internet, but couldn't get it to work.  Eventually I settled with clocking using millis(), which worked reasonably well.

Assembling the Star Wars tunes also proved to be a challenge of its own.  The various snippets that turned up from a quick Google search do not use the same format.  I had to test them separately, then transplant them into this sketch.  The worst moment came when I had an almost-usable sketch at 3am in the morning.  I didn't save in between.  I found the computer crashed and rebooted after waking up.  Arduino actually recovered with all sketches open - but only with the saved version gazillions of revisions earlier. (If you have an unnamed sketch, Arduino will recover to the crash point.  Speaking of irony.)  I had to reprogram based on memory; the tunes, I had to redo them note by note.

A true engineering stumble was in the position of the range finder.  I knew that the best would be to place the sensor low.  But my messy home had so many reflection paths that a low position was apt to trigger false positives.  I even asked my 9-year-old to test the two positions, and saw no problem with ranger on top of the screen.  In the Library, I realized that the adult seating condition only allowed taller children to activate the set! (We were positioned in adult reading room.)  I ended up inviting parents to sit their shorties on their laps.
