Re-purpose Industrial Robotic Arms

September 7, 2010 by Jakob Griffith 53 Comments

We must find out where you can acquire these industrial robots pictured above. Sure, you expect car companies like BMW to have a few lying around, which they used to make into a Twitter message writing robot. But Bungie, a video game company, to have one as part of an advertisement for Reach?

The former is just a scratch on the surface, with some pictures, but a much more decent writeup will be provided after September 12th. The latter has a few videos, and you can watch it recreate a monument with light ‘live’. And while both are impressive uses of old tech, neither answered our first question, we gotta get us one of these.

BeagleBoard Cluster

September 7, 2010 by Devlin Thyne 46 Comments

What do you do after you make a BeagleBoard graphing calculator? [Matt] over at Liquidware Antipasto made a BeagleBoard Elastic R Cluster that fits in a briefcase. Ten BeagleBoards, are connected to each other though USB to ethernet adapters and a pair of ethernet switches connected to a wireless router. The cost for this cluster comes in around $2000 and while consuming less than 40 watts of power, out-paces a $4500 laptop. How might you use this cluster? What improvements would you make?

Firmware Hacking On Behringer Midi Devices

September 2, 2010 by Mike Szczys 8 Comments

A new project called the Unofficial Behringer Control Development Kit lets you tweak or completely replace the firmware on the popular devices. The proof of concept demo shows a custom message scrolling on the 4-character 7-segment display but you can do with the device is only limited by how well you can code for the ARM processor inside. Development takes place using the GNU ARM toolchain but don’t worry, you don’t have to crack the case open to program the chip. The BCR2000 and BCF2000 models supported by the project both run bootloaders that allow firmware updates via midi commands. There’s even a recovery mode if you screw something up. Just make sure you have a direct midi connection for recovery, the USB port won’t work for that purpose. If you need a shove to get you started there’s a nice little example file in the repository.

Flipping Pancakes

July 28, 2010 by Mike Szczys 26 Comments

[Petar and Sylvain] are teaching this robot to flip pancakes. It starts with some kinesthetic learning; a human operator moves the robot arm to flip a pancake while the robot records the motion. Next, motion tracking is used so that the robot can improve during its learning process. It eventually gets the hang of it, as you can see after the break, but we wonder how this will work with real batter. This is a simulated pancake so the weight and amount at of force necessary to unstick it from the pan is always the same. Still, we loved the robotic pizza maker and if they get this to work it’ll earn a special place in our hearts.

Guitar Effect Shield For Maple

July 25, 2010 by Mike Szczys 10 Comments

[Okie] designed this audio effect shield for Maple. You’ll remember that Maple is a prototyping system built around an ARM processor, so there’s plenty of power and speed under the hood. First and foremost, the shield provides input and output filters to keep noise out of the system. From there a set of potentiometers let you change the effect, with the manipulation like echo, distortion, and ring modulation happening in the firmware.

Mouse Controlled Manipulator Arm

July 22, 2010 by Mike Szczys 22 Comments

[Oleg] worked out a way to use his USB mouse to control this manipulator arm. Using a Lynxmotion AL5D (we’ve seen the AL5A previously) he drives the six servos with an Arduino servo shield. A USB host shield handles the HID end for connecting the mouse. The video after the break says it all, [Oleg] has no problem picking up that figurine quickly and accurately. Sliding the mouse controls horizontal movement in all directions. The scroll wheel moves the claw up and down. And holding the left or right buttons what using the control wheel closes or rotates the claw. All we can say is: Bigger, BIGGER!

Arm Mounted Light Cannon; Villains Beware

July 18, 2010 by Mike Szczys 34 Comments

In a hack worthy of the flick Kick Ass, [Chein] built this arm-mounted light weapon. The lamp in the palm of your hand has a ring of LEDs for a nice glowing effect, but the real story is the xenon bulb at its center. The flash capacitor and charge circuit from a disposable camera are used to step up the battery voltage to 330V for an intense and slightly blinding discharge. The charging is started when you press a button on the back of the hand harness, with the flash coming when one of your fingers touches a conveniently positioned trigger. Check it out after the break.

This non-lethal weapon makes for a nice alternative to the dangers involve in playing with fire.
