Plasma speakers

Apparently if you run AC and DC currents through a welding torch flame you can use the resulting plasma as a loudspeaker. [Thanks Cody]

Power metering

The Google Power Meter API is no longer in development but that didn’t stop [Pyrofer] from finishing his metering hardware. It uses a reflectance sensor to read the meter instead of using clamp-based current sensing.

Music videos from inside the instrument

Filming from inside of a guitar creates the camera effect seen above which looks like the waveform you’d see on an oscilloscope. [Thanks Philleb]

Hidden messages in audio files

GhostCoder lets you encrypt and hide audio files within other audio files. The thought is, you can piggyback your own data into Torrents that are circling the interwebs.

2×4 Chair

If you’re skilled with a Skill saw you can make a chair out of one 2 by 4. You can see the pattern you’ll have to cut out from the board in the image above, wow!

Here’s another “useless machine” variant. The trick to this one is that it has dual “fingers” and can work either way. Which way it turns off is selectable via a switch on the side, and the fingers can both be turned on to “fight” each other. Check out the video here.

This video depicts the assembly of a Gameboy MAME-style cabinet. For those wanting to try something like this, this video may fill you in on some of the required assembly techniques, such as how to put decals on the side of your cabinet.

This video featuring the “Autonomous Ultimate Wall-E” shows this robot’s navigational skills around the house. Additionally, it has some nicely actuated arms.

The Verbalizer is a microphone designed to be used with Google’s voice search. It’s also designed with Arduino compatibility in mind and is open-source. Could be a good tool for your next hack.

These clever multimeter probes were built using pogo pins used in electrical test equipment. The springs inside of these pins help keep them planted firmly on the test point in question and reportedly gives a very good connection.

Tripod CNC Machining Setup:

Here’s a strange “tripod” device using the EMC software package generally used for CNC machining. In this case it looks like something that (when scaled up) might control a sky-cam-like device that one would see at football games.

The Off-Grid Container House:

Project to make an off-grid container house. Pretty crazy idea, but definitely not developed yet. This seems like a cool idea, so hopefully this guy will come through. It may give you some other ideas, so check it out. Pizza in a cup anyone?

Iphone Window Pocket

Iphone window pocket – This Instructables article shows how to make a “window” in your pants for your Ipod. The combination of bad style and nerdiness gives a great first impression every time. Not sure how it works with the capacitive touch screen, but it should be good for viewing at least.

The Multiple AC Unit Experiment

Here’s someone who’s done some experimenting with using a central AC unit with several window units. Not bad, considering he documents shaving about 1/3 off his power bill. Maybe it could inspire something even better!

Incredible CNC “hexapod” Milling Center

Finally, this machine isn’t exactly a “hack”, but a professionally designed machining center. It uses a machining setup similar to a delta robot. Six linear actuators are coordinated to allow this CNC robot to move in five degrees of freedom with incredible speed.

Tim wrote in to tell us about this simple hack where he replaced the stock button lights with some really cool Blue LEDS on an ’87 BMW. He uses some capacitors, to achieve the effect that it takes a bit for the charge to drain out so the lights stay on for a bit after being turned off. The lights themselves look really nice, so check out the pic.

Here’s an awesome coffee Table built using a large electrical board. It definitely would look good in anyone’s den, although it most likely has a low wife approval factor (WAF). This is actually based on a “motherboard wall that HAD covered before, but the “coffee table” form probably looks even better.

Finally, after the break is a video of someone washing an interactive art exhibit. Not sure if it qualifies as a hack, but it looks pretty cool to see lights following someone around when he’s washing the screen/window.

Huge, fully functional NES game pad replica

huge_nes_pad

Students at Dutch TU Delft university recently built a huge replica of the original NES controller (Google Translation), which is fully functional and can be used to play games on a large display screen they also installed. How big is it, you ask? It’s about 6 meters wide – over 30 times the size of the original NES game pad and requires participants to jump on the buttons to play.

Convert any image to G-code

bitmap_to_gcode

Members of [Forskningsavdelningen], a Swedish hackerspace, are working on software that will allow users to vectorize bitmap images in order to convert them to G-code files for CNC milling. A good portion of the project is complete, but there is still a bit of work to do, so you won’t see it in action for a while. When it’s ready, we’ll be sure to let you know.

Convert your lame Dead Space plasma cutter into a bonafide laser weapon

dead_space_laser

If you forked out big bucks for the special edition of Dead Space 2, you know how lame the included plasma cutter replica is. Check out this video, that shows you how to convert your LED toy to a dual laser, fire starting, laser pistol. The process is pretty simple, so what are you waiting for?

Synchronized, LED-lit juggling balls

led_balls

[Jonathan] wrote in to share a project he and some friends have just finished. He’s not sharing a ton of details at the moment, but he has put up a video showing off their wireless LED juggling balls. All we know is that they use bright RGB LEDS, Zigbees for communication, and that they are awesome. We can’t wait to hear more about them!

Water cooled PS3 Laptop

watercooled_ps3

[Pirate] recently unveiled his latest work, a water-cooled Playstation 3 laptop. It looks pretty sharp, and can undoubtedly rival some of Ben Heck’s work, even if it does have an external PSU. Obviously having a separate power component isn’t necessarily ideal, but when you are cramming all of that water cooling goodness into such a small package, something has to give!

Custom EBike with a 200+ km range

[Doctorbass] constructed an awesome electrical bike back in 2008 from a Mongoose bicycle. The bike boasts a top speed of 76km/h and a total range of 210 km on a single charge. Some car company needs to hire this guy STAT.

[via Make]

Build to order Xbox 360 laptops

[Ed] recently got his hands on a CNC machine and immediately constructed an Xbox 360 laptop. They look pretty sharp, and he’s willing to make a custom laptop if you are interested. We’re thinking someone needs to organize a contest between [Ed] and [Ben Heck].

A portable GameCube to rule them all

It’s no secret we enjoy portable console hacks around here, and this portable GameCube is quite the looker. Clearly a lot of thought and work went into this mod, and it shows.

[Thanks, Samjc3]

Ultrasonic backup sensor for the parking impaired

If you decided not to spring for those backup sensors on your new ride, [Eric’s] got you covered. He walks us through how he created an ultrasonic backup sensor using an Arduino and an add on programmable logic board.

Mega laser construction begins

Europe’s Extreme Light Infrastructure project is set to start building the world’s most powerful laser measuring in at 200 petawatts. Scientists are betting on the laser to be able to tear apart the vacuum of space and time itself, if only for a fraction of a second. Seems like a solid plan to us – what could possibly go wrong?

[Thanks, KonaStar]

Remaking the first video game

At the Revision 2011 demo compo, a museum project called [MEGA] won first place in the “Wild” category with their zero bit recreation of “tennis for 2”. Entirely made of analog electronics, the retro game completes its presentation on a round o-scope screen. You can see a video of it after the break.

Mint-tin bicycle computer

[Alexdlp’s] newest instructable is a attractive and compact bicycle computer running off of an Arduino, and sports the usual bike features. It does not stop there, adding in a 16×2 LCD gives more room for data in both numeric form and bar graph form, and adding in a pair of radio modems allows that data to be fed back home where it can be logged and compared, perfect for the more serious biker.

8085 Reference Card

If you enjoy retro computers, or would like to make your own, you will find this Intel 8085 reference card is a real treat. Based on a original reference card, it has been expanded to give more detail for additional interrupts, electrical reference, T-State timing, and undocumented instructions.

Connect a SNES controller to your Android phone

[Bruno] wanted to be able to use a real SNES controller with the emulator on his HTC Android phone, packing in an Arduino, 6 AA batteries, and a breadboard and mission accomplished! Hardly as portable as the phone, but we commend the “get it done” sprit. Join us after the break for a quick video.
