Amazing ass… for a robot

Yep, Japan still has the creepy robotics market cornered. Case in point is this robotic posterior. Don’t worry, they’ve included a dissection so you can see how the insides work too. [via Gizmodo]

Time-lapse camera module results

As promised, [Quinn Dunki] sent in a link to the photo album from her time lapse camera module. In case you missed it, she built it in a Tic Tac container and stuck it to the side of a racecar.

Kinect controlled killbot

Didn’t we learn anything from RoboCop? We could totally see this Kinect controlled robot (which happens to weigh five tons) going out of control and liquefying an unsuspecting movie extra standing near it. [via Dvice]

Laser popping domino balloons

apparently [Scott] has set a world record by using a laser to pop a line of 100 red balloons. We enjoy seeing the size of the 1W laser that does the popping… it can’t be long now before we get a hold of handheld laser pistols. [via Gizmodo]

Laser balloon targeting

If that last one was a bit of a let down, you might enjoy this automatic targeting system more. The blue triangle shaped icon is setting a target, the amber triangles have already been targeted. Once all the balloons are identified a laser quickly zaps each in order. Quite impressive, although no details have been provided. [Thanks everyone who sent in a link to this]

Three days of work in 5 minutes

[Celso] bought himself a Ultimaker kit and put together a time-lapse video of him putting it together. There’s a lot of work that goes into these machines, but being able to print a nearly perfect cube on the first run is nearly magical.

How about a CNC mill, too?

The folks over at Inventables have put together a tiny CNC mill kit designed from the fruitful mind of [Edward Ford]. The Shapeoko mill is designed around the Makerslide linear bearing system, so you’re getting a lot of precision very easily. Here’s some more info on the Shapeoko

Update the firmware on your RasPi

[Hexxeh] has been playing around with the Linux images for his Raspberry Pi, so he needs to reinstall the firmware on an image quite a lot. He wrote a tool to automate this task, but it should be useful for RasPi users that want to keep kernel and firmware up to date. You can get the rpi-updater at [Hexxeh]’s GitHub.

Your robotic barista is still always on the phone

Zipwhip is a company that provides a bridge from your phone to your computer so text messages can be displayed on your desktop. To show off their tech, they created a text enabled espresso machine. Everything on this robotic barista is automatic: the cups are grabbed from a warming tray with a servo arm, coffee is automatically brewed, and the last three digits of your cell phone number are printed on the foam to identify each cuppa. Check out the video; action starts at 1:30.

Awesome reading material

If you’re looking for something to read on that fancy tablet computer of yours, here’s every issue of New Scientist from 1956 to 1985. The early 60s issues say fusion power plants are about 50 years away, so we should be just fine in a couple of years.

Homecut – CNC Cutting Directory

homecut

So you have a CNC machine that you use as a hobby, but would like to do some actual work on the side? Or maybe you have an idea you’d like made. Homecut is a map directory where you can maybe hook up with the right person.

The Curta Mechanical Calculator

curta calculator

As [leehart] mentioned in our comments section, the Curta mechanical calculator is a truly ingenious piece of engineering. A quick Google search should find all kinds of information on it, but this article could be a good place to start for some mechanical hacking inspiration!

Luxman Amplifier DAC Upgrade

nand-dac

[R. Barrios] wasn’t happy with using the sound card for his HTPC setup, so decided to add a DAC module onto his reciever. The resulting audio quality was very good, and the build came out quite clean.  Check it out if you’re thinking of a hack-upgrade to your stereo equipment.

3D Printable Tilt-Shift Adapter

tilt-shift-lens

A tilt-shift lens a neat piece of equipment that is used to make a large scene look like they were miniatures. It’s a cool effect, but professional lenses to do this can cost thousands of dollars. This Instructable tells you how to go about printing your own. For more info on the technique itself, check out this Wikipedia article.

New 3D Printer on the Block

3d-printer

If you would like to take the plunge into 3D printing, but are looking for somewhere to get a parts kit, the [ORD Bot Hadron 3D Printer] may be worth a look.  The build quality looks great, and the price for the mechanical components is quite reasonable at $399. You’ll need to provide the electronics and extruder. Thanks [comptechgeek]!

More old computers on FPGAs!

[Andy] loves his Memotech MTX computer. It’s an oldie with a Z80 running at 4MHz; the perfect target for an FPGA port. The ReMemotech has everything the old one has – cassette interface and all – and can run up to six times faster than the original.

Also found in 10-forward

If you’re going to build a jukebox, why not go all out? Here’s a touch screen jukeboxwith an LCARS skin. Yep, the same interface found on Star Trek: The Next Generation.

New desktop wallpaper for you

[McMonster] found a great pair of blog posts (1, 2) showing what ancient ICs look like without their casing. Since these were CERDIP packages (two ceramic plates glued together) they were exceptionally easy to take apart leaving the entire chip intact. Pages are in Polish, but there’s a Google Translate button on the sidebar

Cheap and easy Arduino wi-fi

Quick quiz: what’s the easiest way to get data onto an Arduino wirelessly? XBees? GSM modules? Nope, just get a wireless router and an Ethernet shield. The Ethernet module only cost [Doss] $20, and we’re sure Hackaday readers have a spare wireless router around somewhere.

Chiptunes! Chiptunes I say!

[mdmoose29] has been working on making a custom SNES cartridge for a dubstep artist (tell us more, [moose]…). In his search for programming tools, he found theSNES Game Maker. We tried it out for a bit and it’s still a very unrefined beta. Still, making SNES programming easier is awesome.

You people are awesome. Here’s six things for a links post.

[Valentin] made a night vision monocular from an old VHS camcorder, a small spy camera, and a handful of infrared LEDs. Here’s a video of [Valentin]‘s build in action.

Introducing Hackaday: how it’s made edition

Ever wonder how the make the forms for marine propellers? Now you have. It turns out they use a bunch of plywood, Bondo, and sandpaper. Awesome viewing for a coffee break.

Finally a new way to hurt yourself!

[Darrell]’s solder flux pen was filled and capped at sea level. When this pen made it to his work bench high in the mountains of Colorado there was a significant amount of pressure in that pen. The flux squirted out right into [Darrell]’s eye. Better get some Visine on that, man.

The most accurate television portrayal of hacking ever

[Russell] was watching TV last night and saw an interesting commercial. It’s a bunch of electronic components, then a nook color showing the front page of Make: Projects, an Arduino schematic, and finally a happy robot. Two observations: firstly, someone in media and advertising doesn’t think ‘hacking’ is WarGames stealing bank accounts. Secondly, an ad exec looked into current users.

Here’s the official YouTube video of the commercial.

In a world… where components aren’t soldered… one man… uses a soldering station.

Adafruit linked to the most outrageous promo video ever. This Weller soldering station provides 240 watts, battles alongside Agamemnon at Troy,  has rework tweezers, and travels to Italy to wage war against the Latins.

An IDE for the 21st century

[Chris] is currently developing a new paradigm for programming. He calls it Light Table, and it’s designed to be an improvement over a simple text editor and project manager. All the documentation is at your fingertips, you can make changes on the fly. It reminds us of the zzstructure emulator we saw last year. It’s something to keep an eye on at least.

Sandcasting at the beach

[mkb] sent in a video he found of [Max Lamb] sandcasting a stool at a beach in England. The material is pewter, or >90% tin with a little bit copper and antimony thrown in for good measure. While we’re sure there will be a few complaints from environmentalists, it’s still a cool video to see.

Your project needs an OLED display

Here’s a Kickstarter for a tiny 96×16 OLED display. Connect this thing to any I2C bus and you get a 15×2 character display (or a graphic display if that’s your inclination) very easily. Thanks to [Chris] for sending this one in.

Here’s one for a larf

[Ryan Inman] is suing 20 companies because he got mercury poisoning from vacuum tubes. Read that last line again. Most of the companies that sell antique/repro/hard-to-find components like Angela Instruments, Antique Electronic Supply, and even eBay are listed as defendants in the case. This might put at least one company out of business even though they never sold [Ryan] a vacuum tube edit: they did sell him a neon bulb, and courts are generally idiotic when it comes to technological issues. It’s hilarious and sad, so we’ll keep you updated if we get more info.

Nostalgia, the pain from an old wound

The Adafruit blog posted an excellent piece on the Apple ][ game Rocky’s Boots, an educational game from 1982 that teaches kids how to connect logic gates. You can play this game in your browser, but we’d like to hear our stories of ancient video games that teach you engineering concepts like The Incredible Machine or Widget Workshop. Leave a note in the comments if we’re leaving any out.

A question posed to the community

A company is giving away credit card readers that plug into the headphone jack of an iDevice. [J Smith] writes in to ask us if anyone has gotten one of these and opened them up. Like [J Smith] we’re expecting something a repeat of the CueCat where free hardware is opened up to everybody. If you’ve done a teardown of one of these card readers, send it in.

3DS homebrew

[Mike] sent us a link to [neimod]’s Flickr photostream. It looks like we’re on the cusp of tearing open the Nintendo 3DS for homebrew apps. Someone who uses this much hot glue must know what they’re doing, right?
