Ask any engineer what originally sparked their interest in technology, and almost universally the response will be a Hollywood film or TV robot — Star Wars’ R2-D2, the B9 robot from Lost in Space, or Short Circuit’s Johnny 5, to name a few. Engineers need a creative outlet too, and some pay homage to their inspirations by building elaborate reproductions. At this year’s Maker Faire, droid-builders had their own corner in the center hall, their work ranging from humble craft materials to ’bots surpassing their film counterparts in detail and workmanship.

Probably the most beloved film robot of all time would be R2-D2, and probably the best-known reproductions originate from the R2-D2 Builders Club, who’ve been profiled in Make and Servo magazines, among others. Every kid’s dreamed of building their own R2, perhaps from a wastepaper basket and scrap, but the club’s astromech droids are anything but kid stuff, with machined aluminum domes and intricate motor and sound systems. The club doesn’t sell robots — that would infringe on trademarks — but they do share techniques and component plans. The finished droids (are they ever really finished?) put in appearances at fan conventions and charity events.

Danger Will Robinson! Career inventor [Andrew Filo] has been engineering practical everyday items for three decades, but he cuts loose by bringing his early inspirations to life. His carefully-researched reproductions include an Apollo-era NASA spacesuit and a talking, walking…er, rolling…B9 robot.

Self-described recluse [ELS] is a builder and collector of film props and reproductions. Though he insists his Robby and B9 aren’t perfectly canon, you’d never know by looking; the detail and finish on these two was amazing. Robby is wearable, and periodically through the weekend he’d climb into the suit and entertain a new generation who otherwise might not be acquainted with this Hollywood classic.

[Matthew Ebisu] is obsessed with all things Pixar. As one of the younger makers exhibiting, [Matthew’s] materials may be simpler, but his enthusiasm more than fills the gap. He’s built — and launched — Carl Fredricksen’s house from Up in miniature form. It didn’t quite reach South America, but did net him a pen pal in Nevada. His Autopilot and Eve droids from Wall-E are more craft than tech, so his latest project, along with a gaggle of like-minded friends on his D.I.Y. Pixar fan site, is to develop a working Wall-E robot. So readers — is there a favorite Hollywood ’bot to credit for your passion for this hacking madness? And have you built one yet? A HAL-9000 in your kitchen? Tell us about it in the comments, or if you have a build log posted online somewhere, drop us a link at tips@hackaday.com.

Since the previously-posted stills can’t quite convey the chaos of last weekend’s Maker Faire, here’s some video from the event to help get you through hump day. It’s like three liters of Jolt Cola in a two liter bottle. One thing even video can’t adequately capture is our gratitude toward our readers at the show who took time to express their appreciation for the blog. You guys and gals rock our world. Thank you!

Just when you think it couldn’t possibly get any bigger and crazier, they manage to outdo themselves again. The Bay Area Maker Faire wrapped up Sunday evening, but we have so many story leads that we’ll probably be busy until next year’s event. In the meantime, here’s just a tiny, random sampling of the countless delights that greeted visitors this past weekend.

Setup day was the only time we could get a clear shot of the Hermes space shuttle, [Morris Jarvis’] entry in the suborbital tourist space race.

Early Saturday morning, the line stretches to infinity and beyond.

At the other side of the fairgrounds, scads of locals took advantage of the free bike valet service and scored a $5 admission discount to boot. And this view shows only about half of the bikes present! We only spotted one recumbent parked out here, but quite a few inside as maker exhibits.

So much walking! This kid had the right idea, scooting around in luxury.

It’s not a Bay Area party until the original Doggie Diner heads show up!

Robots were everywhere this year. Of course the R2 Builders Club was on hand…

…but there were no Wookiees present to play chess against this robotic arm.

A row of Anybots, all ready to take up their overlord duties.

Our favorite giraffe joined the rave, replete with his new animatronic head.

The Mondo Spider, like its smaller biological inspiration, manages to be simultaneously fascinating and potentially deadly. It is, however, anything but silent.

Back outside, this MIDI-controlled pneumatic dinosaur alternately entertained and terrified children. We were hoping to witness a one-on-one battle against…

…Saphira, the fire-breathing dragon! Rar!

Nearby, [Haley Duke’s] Swamp Kirin puppet loomed over fairgoers. Kirin, we just discovered, appear to be mortal enemies of efficient JPEG compression.

[Todd Williams’] Land Shark is an animated EL wire-framed skeleton atop a large radio controlled car chassis — a great effect in the dark!

We seem to be on a bitey creature kick. Here, have a Velociraptor head popped out of a commercial ABS extrusion 3D printer.

We posted about the DIYLILCNC mill late last year. What struck us when finally seeing it in person is how it’s anything but li’l. This thing bullies RepRaps and takes their lunch money!

They were even making something in the Maker Shed store. What exactly? We’ll give you a hint: it’s printed with green ink on the back. Man, they got us good. Went in needing just one Parallax RFID reader, and somehow couldn’t leave before spending the equivalent GNP of Guam.

This is here just for blog cred.

Our hats are off — again — to SparkFun Electronics. These guys could’ve easily brought enough neat stuff to bankroll their retirement from this one show. Instead, they taught kids how to solder. How cool is that?

FPGA pr0n from Art Magnitude’s ORB v.2, a persistence-of-vision globe on a grand scale.

There was always a line waiting to play with Tangile interaction’s digital graffiti wall.

This way to the egress! If we’ve overlooked or glossed over your favorite subject or display, it may be that we’re expecting to cover it in more detail in the future. Keep your eyes peeled for more wild stuff here!

If you’re like us you’ve got quite a few prototyping tools that are bare PCB boards. If you’re using them a lot you might want to protect them with some type of case but the lack of mounting holes can make this difficult. One popular solution to this problem is to design a case for a perfect fit, then cut it with a laser or print it out of plastic. We’ve got examples of both. [Stewart Allen] set to work designing laser cut cases for the AVR Dragon and the Bus Pirate V2go after seeing our post about on-the-go prototyping. We think this is especially important if you have an AVR Dragon as it’s been known to bite the dust if the bottom is shorted out. If you have access to a laser cutter you can download is DXF files and the models and cut your own. If you don’t have a laser cutter but can get some time with a 3D printer check out the Bus Pirate V2go printed case and the Arduino printed case.

Let’s face it, the original Xbox is ugly. It might have looked cool when it first came out but now most would be embarrassed to display that old beast with the rest of their entertainment hardware. This is unfortunate because the old girl still has some life in her. If you have tools, time, and talent you can give the box a facelift and bring it back to see the light of day. We’ve got six of our favorite Xbox to Home Theater PC hacks after the break to inspire you.

Xbox mini by [Ghostavel] This case was designed in autocad and laser cut from acrylic. The DVD drive was and the HDD swapped for an 80gig laptop drive to save space. A different heat sink and fan added to both the GPU and processor to keep this puppy cool and quiet. To the right in the foreground you can make out a tiny PSU.

Pioneer DVD Case by [Barney_1] DVD players are designed to sit in your entertainment center and that’s why they’ve been a popular home for Xbox guts. This hack removed the standard AV connector from the Xbox board and routes those solder points to the connections on a Pioneer DVD player case. An LCD display resides in the window for the DVD player’s display, and a PC DVD-Rom (not pictured above) takes the place of the original DVD tray. The power and eject buttons have been wired to work and the original IR receiver wired to the Xbox dongle, leaving the appearance (at least from the front) completely unaltered.

Xbox Slim by [Coca627] This case is made from methacrylate. The hardware changes include a smaller PSU, a slim DVD-rom, laptop HDD, and added USB ports. WiFi and wireless controllers have been included in the design. The white is a nice touch and will complement that white Wii that looks lonely next to the rest of your black components.

Minibox by [Themikesssta] This is more of a mod than a hack but it’s a pretty amazing one. On the hardware side he did remove some capacitors for less current draw during boot. The DVD and HDD have been swapped out for smaller ones and an LCD display has been added. The case is made from MDF but it’s the paint job that makes this look so good. There’s a total of five coats on this tiny box.

Xbox Micro by [Bandit5317] We featured the Xbox Micro last year because it’s a marvel of slimness. It’s got a laptop HDD and long-thin PSU and almost nothing else. Some serious shoe-horning had to be done to make the package this thin, and the finished look greatly benefits from those efforts. Svelte XBMC by [Richard Wileman] There’s not much info on this case but we think it’s rather sexy so we’re throwing it in. As you can see, the DVD drive is gone, the HDD is smaller, and cooling has been upgraded with a fanless heat-sink and two case fans. The controller ports were rerouted to the rear of the case and the IR dongle has been built in for use with a remote control. The case cover has a grill above that massive heat sink and we’d be interested in finding out if both case fans are pumping air out of the case, in effect pulling a ton of cool air past the CPU.

Happy New Year and happy hacking to all. We had a great time last year exploring the creativity in the hacks that make the Internet a better place. Below you’ll find the nine most popular posts of the year here at Hackaday. Now’s the time to get working on that great project you’ve had in mind. Let us know once you’ve pulled it off and maybe you’ll be on this list next year!

We asked for CNC projects, and wow did you guys deliver!

First up is [J-J Shortcut's] MDF based CNC. He’s made three thus far, with the most recent costing about 180 euro and taking 2 months to build.

[Qwindelzorf] has also constructed a multitude of CNC machines including this industrial size router and this smaller miller.

Finally, [Mick's] large steel CNC which just made its first cut only a week ago! Keep up the great work guys, CNC machines are not easy to build and your accomplishments are ones for the record books.

Alpha-Geek Clock Oh this one’s good! This clock has a built-in WWVB receiver to make sure the time is always accurate. But with just one LED as the display we wish you good luck when reading it! A whole bunch of info (time, day, year, etc) is blinked out in binary encoded decimal. [Thanks Tymm]

Standard Time Manual labor. This clock is an art installation in Rotterdam. In the video you can see that workers changed the segments of a four-digit display every minute over a twenty-four hour period. Since they filmed it we’d expect the ability to turn this into a video clock like the one we saw last week. [Thanks David]

International Clock Low-tech but highly creative. The instructional video uses basic geometry and the workings from a cheap clock to craft an international clock. There are twelve labels corresponding to different time zones. Put the zone you want up and read the clock as normal. [via Red Ferrett Journal]

Princess and the Pea There are few who will agree to have an air tank as part of an alarm clock. The Princess and the Pea concept uses compressed air to inflate an exercise ball in between the mattress and the box spring. Watch this video to see how it will roll you out of bed if the hissing air sound didn’t wake you first. At least it’s more gentle than the pneumatic alarm clock from last June. [via Neatorama]

Tomorrow’s turkey day here in the United States. Do you fully expect your trashy neighbor to burn down his house while trying to cook a holiday feast? To see what’s in store for your neighborhood we’ve rounded up a great collection of idiots deep frying turkeys.

Let’s set up the fryer on our wooden deck… now that it’s a flaming pyre what should we do?

“Ow my toes” – Boiling oil v. sandals

Get the extinguisher… wait, I don’t think that’s working.

Let’s learn about liquid displacement.

[Alton Brown], the consummate kitchen hacker, has been kind enough to share the safe method of deep frying turkey. This includes how to measure for liquid displacement, and how to build a derrick (PDF) to lower the turkey into the pot from a safe distance.

Here’s a collection of simple hacks you can do in between larger projects. After the break we’ll look at converting an iPod from hard drive storage to Compact Flash, build an LED desk lamp using LEGO and USB power for charging, and use an Arduino shield to add network control at the touch of a button. iPod HDD to CF Conversion

[Richard] tipped us off about converting an iPod from a hard drive to a Compact Flash card. We actually did this a few years ago. Because we frequently buy broken electronics we had an old iPod 20GB with a broken HDD. Knowing we had seen one wire-porn type diy adapter and reported on another, a quick search produced a ready-made solution. [Richard] went the same route by purchasing a CF to 1.8″ IDE adapter and a 32GB Compact Flash card. Just crack open your iPod, unplug the broken HDD, plug in the adapter and CF card, close the case, and go through a normal iPod recovery cycle.Compact Flash is considerably cheaper than solid state hard drives which makes this a cheaper conversion than a comparable Zune upgrade. There you have it, what once was broken is now whole. LED LEGO Lamp

[chAos] put together a desk lamp with parts he had on hand. A broken Bluetooth headset was used for the switch, battery, and USB charging capabilities. From there he built an articulated arm and body out of LEGO. The final step to provide illumination was just a matter of wiring up a white LED. This isn’t the most beautiful LED lamp build, but it gets the job done and adds a little “I built this” pride to your desk. Mute button connected via the network

[Justin] needed a mute button for some speakers at the other end of the room. The music was played by a Mac mini so he built a mute button that sends commands over a network. By using an Ethernet shield for an Arduino he’s able to detect a button press and send commands over an XML-RPC server to get some peace and quite around here. The device gets its electricity by using power over Ethernet. The Ethernet shield is one of our favorite add-ons, taking on the brunt of the work in getting connected. Don’t be afraid to send in hacks of all difficulty levels. If you’ve got one that’s a bit simpler, we may feature it as part of a group.

Friends, pilgrims, send us your hacks. Most especially, your Thanksgiving hacks. We had a wonderful time over the past six weeks collecting and highlighting your Halloween props and now it’s on to the next holiday. Did you build your own deep fried turkey rig with some special features? How about that pie making robot you built for last year’s celebration?  Can’t live without your twittering cornucopia? Document it and send it to our tip line! All Thanksgiving themed hacks will be considered but only the well documented and creative entries will be featured. If you just joined us, here’s a roundup of the Halloween Props we encountered this year:

Halloween props: Techy Jack-o-lanterns Halloween props: Servo eyes Halloween prop: glowing spooky eyes Shift powered pumpkins Animatronic winged demon terrorizes local garage A modular Halloween with grid beam Scare ‘em silly with a moving pumpkin Halloween prop: Bigmouth billy bass Halloween props: Low cost popup Quoth the Raven: hack some more Halloween prop: portable black light Halloween props: DMX controlled skeleton Halloween prop: the ground-breaker Piecax the Poltergeist reinvents the Knock Block Halloween props: Alien Costume Halloween Props: Pie of Sauron Halloween props: Skeleton springs from coffin Halloween prop: DIY fog machine Halloween props: flying crank ghost

disclaimer: boiling oil is dangerous, that’s why it used to be used for torture. Always consider your own safety! [Turkey photo source]

The Atmega168 at the heart of every Arduino is an eminently capable chip; its ilk have been seen working as a basic web server, playing back digital audio, even generating TV signals. But as projects continue to grow in sophistication, reality rears its ugly head: Arduino can handle any one of these tasks very well, but it often requires squeezing every last instruction cycle or bit of memory in the device. Even the ’368 chip and the Arduino Mega are stopgap measures. Sooner or later, you have to graduate to long trousers—move up to a more capable microcontroller platform—an uncomfortable change usually involving a hefty investment in new hardware and an intimidating learning curve. Leaf Labs’ Maple aims to change all that…

Maple, expected to ship in October for about $40, brings together the STM32 microcontroller, a 32-bit 72MHz beast of a chip, with the familiar Arduino footprint and even compatible library functions. Users can jump right in, preserving their existing investment in Arduino shields and know-how, then expand their repertoire with the new capabilities afforded by this beefier processor. But Maple is not the first. Coridium Corporation’s $30 ARMite PRO (below) is a 60MHz ARM7 board that’s pin- and footprint-compatible with Arduino Pro. The CPU isn’t quite as powerful as the STM32, nor do they provide Arduino-compatible libraries, but it’s still a significant step up from the Atmega and is available today.

Also worth mentioning, though it lies in an entirely different direction, is Raisonance’s STM32 Primer (also called the STM32 Circle), shown below. This kit is neither hardware- nor software-compatible with Arduino, and the bundled software tools are Windows-only, but it’s similarly affordable (about $40), self-contained (no external programmer), and will give you a head start with the STM32 chip right now. And while you can’t bring your Arduino shields to this party, the Primer brings its own fun: a color LCD, 3D accelerometer, and rechargeable battery. The original “Circle” Primer is a little tricky to track down, but a little Google searching can help here. A “Primer 2” with more features has since been released, if you don’t mind paying half again as much.

Maple is just the first of several increasingly powerful Leaf Labs projects that are planned. FPGAs and gigahertz-speed CPUs are in the pipeline.

Here is a classic project used to increase wireless signal strength. Cantennas focus using a waveguide very much like a magnifying glass focuses light. [Robert] made a Natural Light beer cantenna, pictured in the upper left. His approach used three beer cans, a paper towel holder, and a shower curtain rod. On the tipline, he noted a signal boost from 11Mbps to 54Mbps. This is certainly something we can hack together if our room lacks adequate signal. Read about parabolic and seeking versions after the break.

The lower right image is an example of a parabolic soup cantenna constructed using an old satellite dish. No figures seem to be cited, though the construction is worth noting. We’ve had success with old satellite dishes in the past. The upper right and lower left pictures are scanning Cantennas. They use servos to seek out stronger connections by moving and checking the signal strength. Below is an in line video of the lower left cantenna while scanning. Maybe you want to know How to build a tin can waveguide WiFi Antenna. All the instructions are provided complete with a rough cost break down, and the site has a calculator to determine cut off frequencies given a can’s diameter.

With the 4th of July around the corner, we thought it would be a good idea to give a controller wrap up and show you how to make some ignitors. Last year we covered a microcontroller based fireworks launcher. If you like the idea of a controller but don’t want to run all the wire, we have the wireless fireworks controller. Adding a little twist to the wireless scene are cell phone triggered fireworks. Maybe controllers are not your cup of tea, you could try to microwave your fireworks. After the break we show you how to make ignitors from a diode and a match.

Using a 1N914 diode, match, and 4 ohm ballast you can make your own ignitors. Using the leads for support, the diode is attached to the match. A current is passed through the device to cause rapid heating. The match head and component must touch one another, in order to ignite. In the video embedded below we show you exactly how.

Vacuum formers are still fairly rare in our community, so it was a surprise to see that in the 1960s Mattel marketed one as a toy. It used a hot plate to mold plastic sheets into various shapes. The design was updated by Toymax in the early ’90s to use a light bulb heating element to make car bodies, like some sort of manly Easy-Bake Oven. The home-built machines we’ve seen are a much larger scale. In 2005, we posted [Ralis Kahn]’s version that employed an electric grill as the heating element. [drcrash] has since built on those plans, hoping to develop an even cheaper device. [via Gizmodo]

Every year, as it gets cold, many of us put our faithful two wheeled companion away for the winter.  Despite that, there have been a veritable smorgasbord of bicycle related projects posted to instructables this last week. In honor of our human powered transportation, lets take a peak at a few projects. Bicycle safety is always paramount. They can be fairly difficult to see compared to a car. There are many ways to make them easier to spot, such as wrapping them in reflective material, or adding blinking tail lights. Even if people do see us, they often have no idea where we are planning on going. To remedy this, we can always add turn signals. It can also be hard to see where you are going at times. Adding a head light, or helmet light can really help. If you’re not a big fan of LEDs and want a little retro flair, you can always add an oil lamp. For those who live in warmer climates, or just can’t give up their bicycles, you may wish to add some festive decorations. Covering your bike in Christmas lights doesn’t look too difficult, and a CFL lit wheel is a cheap way of adding some cool effects.       

We’re barely past Halloween and people are already working on their next LED based holiday decorations. For Hanukkah, Gizmodo pointed out the PCB menorah pictured above. It uses a set of DIP switches to control which LEDs are lit. A couple years ago, Evil Mad Scientist Laboratories put together a tutorial for building a more minimal LED menorah. Each of the nine LEDs are soldered directly to the legs of an ATtiny2313 microcontroller. Every time you power up the device an additional LED is lit. [Ori] liked the project and decided to take a slightly different approach. He used an LM3914 DIP18 LED bar driver. A potentiometer controls how many of the LEDs are illuminated.       

With the election coming up in less than a week, voting machine security (or the lack thereof) is critical, especially with the popularity of early voting this year. While we’ve previously discussed voting machine insecurities, it looks like the problems haven’t been fixed, and in some cases, it’s escalated. Voters in states like West Virginia and Tennessee have complained about voting machines “flipping” their votes, even after they were recalibrated as in the video above. Voters have been advised to avoid voting straight Republican or Democratic tickets, to avoid the likelihood of their votes being flipped. What if you actually do want to vote a straight ticket? Video the Vote is an organization that advises documenting as much of your voting process as possible. Other ways you can protect your vote include voting absentee so that a paper trail is available, and refusing to accept provisional ballots, which are often thrown out. After seeing videos of ROM swapping and finding out that the locks can be opened with hotel minibar keys, we’re waiting to see what’s going to fail this year… and voting absentee.       

Yesterday, Gizmodo published a roundup of wearable gadgets for people who “don’t mind looking like a tool”. It’s interesting to see what has been deemed commercially viable and put into mass production. The list covers HMDs, embedded WiFi detectors, integrated keyboards, tech jackets, speaker hats, and others. We thought you might find some inspiration from the list for your next project. In the past, we embedded a WiFi detector in a backpack strap for our Engadget how-to. The natural choice for wearable projects is the LilyPad Arduino which was featured most recently in the turn signal jacket. [photo: cksthree]
