N64 Controller Mod Means Playing Games Akimbo

Star Wars Episode 1 Racer for the Nintendo 64 has a rather interesting feature: by entering the code RRDUAL on the cheats menu, it’s possible to plug two controllers into the console and control each engine independently. This gives the game an awesome arcade feel, but dual-wielding N64 controllers is a bit of a burden. [Clarky] thought it would be a good idea to combine two controllers into one, and the Star Wars Racer controller is the result.

Like most console mods, the build began by tearing apart two N64 controllers and gluing them together. With a ton of bondo, sanding, and fiberglass, [Clarky] had a mutated N64 controller perfect for the Episode 1 game.

[Clarky] will be updating the build with a built-in rumble pak, but for now he’s doing his best to learn how to fly a pod racer with both hands. You can check out the demo of his build after the break where he plays the Star Wars game as well as a round of Goldeneye using his akimbo controller.

Turning An Old Keyboard Into A Work Of Art

 

The 1970s were the glory days for analog synthesizers, and for [Stefan] listening to huge modular Moogs and ARPs resulted in a wondrous seething jealousy. In 2009, wanting to relive just a little bit of his childhood, [Stefan] picked up a PAiA Stringz’n’Things from eBay. It’s a great little keyboard, but [Stefan] his new purchase to look little classier than a tolex-covered flight case. After getting rid of the old tolex case, [Stefan] made a new enclosure and added some extra circuitry to expand the capabilities of this classic synth.

After replacing the electrolytic capacitors and fixing a voltage regulator issue, [Stefan] made a new enclosure for his keyboard out of beautifully lacquered mahogany. A new key bed stolen from an old Yamaha organ was brought in, and new control panels above the keys provide a more sensible organization than the keyboard’s previous incarnation.

The original Stringz’n’Things was laid out more like an organ than a synthesizer, a reflection of its polyphonic nature. This meant there wasn’t a very diverse tonal palette, but [Stefan] remedied that with a wave folder to generate extra harmonics, a tremolo, and an envelope generator to provide attack and decay for each note.

Now [Stefan] has a lovely polyphonic synth that has found its place on top of an old Hammond organ. As a bonus, the synth sounds really good. Not bad for an instrument generally regarded as being very limited.

 

 

 

Mars Science Laboratory Lands Today

[youtube=http://www.youtube.com/watch?v=P4boyXQuUIw&w=470]

Since launching on November 26, 2011, the newest Mars rover Curiosity has been speeding towards the red planet. Its days in the harsh vacuum of space are numbered as Curiosity prepares to land in just a few hours.

The landing of Curiosity at Gale crater is scheduled to be received on Earth at Aug 5, 10:31 pm PDT / Aug 6, 1:31 am EDT / Aug 6, 5:31 am UTC. The latest updates on the success or failure of ramming into the Martian atmosphere should be available on NASA TV and this feed from JPL. There’s a huge bunch of feeds on spaceindustrynews.com, and of course the Twitter for the wonderfully anthropomorphized Curiosity.

If landing a Volkswagen-sized, nuclear powered robot on the surface of Mars isn’t cool enough, we’ll also see a picture of the descent from Martian orbit via the Mars Reconnaissance Orbiter. The Atlantic has a bunch of awesome pictures showing off Curiosity’s preparation for launch. Of course there are videos after the break including one by [Stan Love] explaining why it’s soooooo hard to get to Mars.

Android Controlled Robot Extravaganza

We have no idea why, but since we featured Botiful, the Android-powered telepresence robot a few days ago, the tip line has been awash in robot/Android mashups. Here’s a few of the cool ones.

Using an Android as a remote control

[Stef] used a Samsung Galaxy S3 to control an old rc tank. The Android sends accelerometer and gyro data over Bluetooth to an Android where it powers a pair of H-bridges to turn the wheels.

Turning Android into a Robotic Operating System

ROS, or the Robot Operating System, provides a bunch of utilities for any type of robot such as point-cloud mapping to multi-joint arm control. [Lentin] sent in a guide on installing ROS on Android. So far, he can get accelerometer data, stills from the on-board camera, have the robot speak and use the small vibrator motor. Here’s a (somewhat limited) demo of [Lentin] playing with ROS in a terminal.

“Just a quick procrastination project”

Last May, [Josh] wrote in asking if a tread-based robot controlled through Skype would be a cool idea. We said ‘hell yeah’ and [Josh] scurried off to his workshop for a few months. He’s back with his tank-based robot. One really interesting bit is the robot responds to DTMF tones, allowing it to be controlled through Skype without any additional hardware. That’s damn clever. You can see a video of the SkypeRobot after the break.

Large Version Of Operation Isn’t Much Easier Than The Original

Last weekend at the Detroit Maker Faire, the folks at the Lansing Makers Network brought a large-scale version of the classic electronic board game Operation.

MegOperation, as the Lansing hackerspace calls their build, is a gigantic printout of the chronically ill guy from Operation plastered onto a sheet of plywood. Wire loops surround each incision to detect when a surgeon’s unsteady hand when retrieving unnecessary body parts. These wire loops are connected to an Arduino that regulates the bell and light-up nose the team didn’t quite have time to finish.

Even though the team used an Arduino for their large-scale version of Operation – a game that doesn’t require any electronics besides a battery, wire, and buzzer – breaking out each body part to a separate Arduino pin seems pretty smart. A processing app keeps track of the time elapsed for each operation and can detect when the wire surrounding a particular incision is touched, perfect for competitive Operation play.

You Are A Sack Of Meat, Easily Punctured By Stompy

 

It may not be as cool as a bear riding a jet ski on a shark in outer space, but Stompy, the giant, rideable walking hexapod comes very close.

A few months ago, we caught wind of a gigantic rideable hexapod project brewing at the Artisan’s Asylum hackerspace in Somerville, MA. The goal was to build an 18-foot wide, two ton rideable hexapod robot, with the side benefit of teaching students how to weld, code, and other subjects related to giant machines and mechatronics.

The Stompy team has now launched a Kickstarter asking for donations to pay for the materials, plasma cutting, and other bits of hardware required to make Stompy a reality. Since there isn’t much information on amateur level hydraulics, the project is open source; the trials of building Stompy will be made public freely available for any other giant robot project.

Team Stompy has successfully built, debugged, and tested a half-size prototype of one hydraulically powered leg that is able to ‘row’ across the floor under its own power. This is a huge achievement for the team and now they’ll move on to the full-size single leg prototype.

You can see the team’s single leg prototype in action after the break.

Ask Hackaday: What’s Your Backup Solution?

Here’s some very, very sad news from [Charles] over at The Maker’s Workbench: on July 16th, his house was hit by lightning causing his workshop to catch fire. His family is safe, but unfortunately thousands of dollars in gear has gone up in smoke. [Charles] lost a Reprap, a ton of dev boards, a huge amount of tools including an awesome soldering setup, and his laptop and file server.

Short of taking up residence inside Yucca Mountain, there’s little that can be done to prevent random, disastrous acts of Thor. The only bright side to [Charles]’ ordeal (if there is one) is that most of his file server – including all the code he’s written over the years – was backed up on the cloud.

Hackaday readers aren’t much for marketing buzzwords like ‘the cloud,’ so we’re wondering what your backup solutions are. If the cloud isn’t for you, is a NAS at home a good idea? rsync will do wonders, but even hard drives at an off-site location fail; maybe tape is the best choice. Of course if you have a laser cutter, there’s always the option of cutting patterns of holes in stainless steel plates and preserving your data for thousands of years.

If [Charles]’ story doesn’t inspire you to backup often and preserve your data, consider this: the greek poet [Sophocles] wrote 123 plays, seven of which still survive. Put in perspective, that’s like the only songs in The Beatles’ catalog surviving 2,500 years coming from the Yellow Submarine soundtrack.
