Tekken Piano

Mc Cool hooked up a MIDI-capable piano to the control inputs of classic fighting game Tekken, thereby synchronizing the on-screen action and musical performance. Then he recorded video of him doing online battle. He won!
This is the final product of my project for interaction design. Took the whole semester, to get this to work but it was worth it. How it works: The piano sends a Midi-Signal, which is transferred to an arduino. According to the signals, the arduino triggers transistors, which then trigger inputs on a paewang PCB (This is the PCB of an arcadestick). The paewang is connected to an Xbox360 (you can also use it on PS3).

Make a drawer that opens with your secret knock

A couple of years ago inventor Steve Hoefer wrote a how-to project for MAKE called the Secret Knock Gumball Machine. You record a special knock pattern by rapping your knuckles against the case. After that, only people who enter the correct knock pattern get a gumball.

Recently Steve made a Secret Knock Drawer Lock and wrote a tutorial for Adafrut’s learning site.

Steve remarks, "I’ve built this project a dozen times and every single time I finish it, it makes me incredibly happy to see it work. Even though I know every detail of it, it still feels a little bit magical." Indeed!

3D printed, trainable robot arm with Arduino controller

Joly sez, "Maker navic09 demos a prototype trainable robotic arm, made from 3d printed parts, an Arduino, and Adafruit analog feedback servos. Inspired by the Baxter robot, this arm can be trained to move with your own hands. Once the train button is pressed, you move the arm and gripper as needed while the Arduino stores the positions in EEPROM. After that the arm will replay the motion as needed."

The gripper and arm are on Thingiverse.

AutoDesk announces free electronic circuit design app

DC Denison of MAKE says:

Autodesk today expanded its suite of free 3D tools by partnering with to launch an electronics design tool: 123D Circuits.

The program allows users to create virtual breadboard-based designs to build and experiment with circuits. A virtual Arduino board can be added to the design, and the code can be edited in a browser window and simulated. The code can also be edited collaboratively (“a Google Doc for electronics” Autodesk claims).

The program also provides hooks that allow users to have the virtual boards professionally manufactured.

Arduino-controlled pelvic-floor strength-tester, with light-up penis

Last September, Doctor Kristen Stubbs -- a roboticist who makes sex-gadgets for her Toymaker Project -- released a video (NSFW) demonstrating her prototype pelvic-floor strength-tester, called "The Hammer." The Hammer has a bulb that is internally inserted, containing a squeeze-sensor, and a penis-shaped, light-up readout that protrudes between the wearer's legs. The harder the wearer squeezes, the more the readout lights up.

Right now The Hammer has two modes: the test-your-strength game, where the more you squeeze, the more it lights up; and a demo mode which cycles through all of the colors of the LEDs.  Soon I hope to connect the Arduino to my Android phone, and then I’ll be able to do even more cool things!

I’ll be following up on this with more technical details over the next few weeks. (Update, 10/11/12: If you would like to hear me talk about how I made The Hammer, you can see some excerpts and my slides from my technical talk at Arse Elektronika 2012.) My plan is for The Hammer to become an Open Hardware project.  This is still very much a prototype, but I would be thrilled if anyone else wanted to build their own.

30 Arduino Projects for the Evil Genius

I had a lot of time on my hands this holiday season and decided to get an arduino kit (I have solar panels I want to aim for max efficiency during the day, on a VW van.) A lot of intro titles seemed interesting but Simon Monk's 30 Arduino Projects for the Evil Genius grabbed my attention. Good title!

Sadly, this is no guide to building shark-mountable lasers. There are however a lot of simple, short projects that help you understand building with an arduino controller. Monk uses very clear pictures and schematics to show what needs doing. His text is precise and understandable. The steps are easy to follow and the thing you should learn from an exercise is blatantly obvious. Most importantly these projects are fun! I'm not just making an LED blink or a speaker chirp when I work with this book. Projects like the temperature monitor and computer controlled fan are giving me the foundation I need to aim my solar panels. The results and functions are easy to apply to the types of things I want to do with an arduino.

Lasers would have been nice.

Electromagnetic Field: a UK geek/maker/hacker weekend campout

Jonty sez,

Electromagnetic Field is a three day camping festival for hackers, geeks, scientists, engineers, artists, and crafters. From the 31st August to the 2nd September we'll be taking over a field in Milton Keynes and turning it into a place for makers and breakers to meet, build and learn from each other.

Throughout the event there will be talks and workshops on a huge variety of things, from gene therapy to welding, lock picking to electronics, DNSSEC to drones, and crocheting to carpentry. The camp is fully equipped with power and internet to every tent, and each attendee receives an Arduino-compatible wireless camp badge to hack on. We are encouraging people to set up campsites with friends, and we'd like to offer a limited number of discount tickets to Boing Boing readers!

Makie doll with expressive animal ears

Katsideswide has modded her alpha-version Makie doll with a pair of expressive animal ears. She drilled holes in the head of her custom, 3D printed dolls, used the head-cavity to house a controller, and went to town.

Ok, i've just started tinkering around with some tiny servos to get Suekat expressing herself. I'm yet to get the drill out to perform amateur surgery on her skullcap but I'm hoping the results will be exciting! I don't want to promise anything yet but I've hooked up an arduino pro mini, and the conveniently sized head cavity means I think i can get a fair amount in there. It looks like there's a handy hole in the neck leading to what looks suspiciously like a space for a battery in Suekat's back. Unfortunately I can't get a standard 9V battery into the space! It's a fraction too small. I was wondering what battery it was designed for? And if there's any chance I can get 9V out of it?


(Disclosure: I'm proud to say that my wife co-founded MakieLab, manufacturers of the Makie dolls) Read the rest

HOWTO open an electronic hotel-room lock without a key

Cody Brocious -- a Mozilla dev and security researcher -- presented a paper on a vulnerability in hotel-door locks last month at Black Hat. Many electronic hotel door-locks made by Onity have a small DC power-port that also supplies data beneath them. Brocious showed that if he plugs an Arduino into these locks, reads out the 24-bit number sitting there, and re-transmits it to them, some appreciable fraction of them (but not all of them) spring open.

Testing a standard Onity lock he ordered online, he’s able to easily bypass the card reader and trigger the opening mechanism every time. But on three Onity locks installed on real hotel doors he and I tested at well-known independent and franchise hotels in New York, results were much more mixed: Only one of the three opened, and even that one only worked on the second try, with Brocious taking a break to tweak his software between tests.

Even with an unreliable method, however, Brocious’s work–and his ability to open one out of the three doors we tested without a key–suggests real flaws in Onity’s security architecture. And Brocious says he plans to release all his research in a paper as well as source code through his website following his talk, potentially enabling others to perfect his methods.

Brocious’s exploit works by spoofing a portable programming device that hotel staff use to control a facility’s locks and set which master keys open which doors. The portable programmer, which plugs into the DC port under the locks, can also open any door, even providing power through that port to trigger the mechanism of a door lock in which the battery has run out.
