[Russel Munro] decided to go all-out for his son’s birthday cake: he made a Transformers robot cake that, well, transforms from a truck into a robot, Optimus Prime style. His impressive build has the actions of the original: first, the front rears up to lift the head, then the back lifts to form the body and the head and arms pop out of the top. Underneath the thin fondant exterior is a 3D printed body, driven by a mechanism in the base. He used fishing line to lift the parts, which is pulled by a motor salvaged from a CD player, being driven by an EasyDriver board from Sparkfun.
The main issue he had to overcome was weight: apparently he underestimated the weight of the fondant that covers the cake, and had to do some last-minute work to strengthen the drive mechanism, and skip plans for the more ornately decorated version that his wife had planned. But the look of glee on his son’s face when he operates it at the party is the best bit. In these days of CGI and computer games, it is good to remind the kids that there is still a lot of fun to be found in ingenuity and liberal quantities of hot glue.

There’s just something about the idea of robots turning into everyday objects that fascinates us all. It seems Japan outdoes the world in that category, and the J-Deite project is no exception. J-Deite Quarter is the first transforming robot to come from the collaborative project between [Kenji Ishida] of Brave Robotics, [Watur Yoshizaki] of Asratec Corp., and Tomy Co. Ltd. If Brave Robotics sounds familiar, that’s because this isn’t the first transforming robot [Kenji Ishida] has produced, nor the first featured on Hackaday.
The J-Deite Quarter weighs 77lbs (35kg) and can run for an hour on a single battery charge. It’s joints are powered by Futaba servos. It is controlled by the proprietary V-SIDO OS designed by [Watur Yoshizaki]. As a robot, it stands at 4.25 feet (1.3m). It walks at a rather slow speed of 0.6mph (1km/hr). It has several points of articulation; it can bend its arms and flex its fingers. In less than 30 seconds, the robot transforms into an equally long two-seat sports car with a maximum speed of just over 6mph (10km/hr). Overall, the J-Deite Quarter is no speed demon, but it is noteworthy for being functional in both forms.
The web site has a cute backstory featuring a green meteorite that allows the “real” J-Deiter to communicate with the developers trying to create a robot in its image. Along with the video, it resembles a marketing ploy for a toy, which could explain Tomy’s involvement. After all, Tomy, along with Hasbro, developed the original Transformers toy line. Unfortunately, the J-Deiter Quarter is just a prototype, with no plans for mass production at this time. Instead, the project’s focus is on making a bigger and better J-Deiter. There are plans for a J-Deiter Half (8-foot-tall) to be developed by 2016, with the final goal of creating a 16-foot-tall transforming robot by 2020.
Enjoy the video that shows what J-Deite Quarter is capable of (with added sound effects, of course) after the break. Now, if you’ll excuse me, I have a sudden hankering to watch some Transformers and Voltron cartoons.

[Tez_Gelmir] built an awesome portable workbench. Not satisfied with just mundane designs, he patterned his box after Soundwave from the classic Transformers: Generation 1 series. This portable bench keeps his tools organized and ready to roll out.
[Tez] has all the basic tool groups covered – screwdrivers small and large, pliers, crimpers, soldering iron, fume extractor, vice, and wire spool. He’s also got room for parts boxes to hold his components.
The basic box is built from a single sheet of 7mm plywood. The front work area is a smaller piece of 12mm plywood. Working with 7mm plywood did prove to be a challenge – [Tez] had to use some very small screws for his hinges. The basic box construction was easy though – [Tez] used a pneumatic nailer and PVA (wood) glue.
[Tez] used a number of 3D printed parts in his design. He kept the Transformer theme going with a Decepticon logo built into his screwdriver holder. The fume extractor and lamp were also especially clever – [Tez] mounted them to drawer sliders, so they are there when he needs them, and out of the way when he doesn’t.
[Tez] spent quite a bit of time setting up his power system, and it shows. The inside of the box is framed with four power points. The main cord has its own “mouse door”, and everything tucks neatly away when not in use.
The Soundwave paint job is what sets this box apart – [Tez] spent quite a bit of time getting everything just right. It looks like Ravage is ready to spring out at any moment.
We really love this setup – Our only suggestion would be to add some sheet metal to protect the corners of the box while in transit.

Yes, that’s exactly what you think it is. A Transformer. That transforms into the TARDIS.
This masterpiece of pop culture is the work of [Nonnef] over on Instructables. After the inspiration to create this work of art struck, [Nonnef] started modeling this Transformer and TARDIS in clay to make everything fit together just right. After a good bit of 3D modelling, the Doctor’s robotic wife was ready for printing.
If you’re going to print one of these for yourself, be prepared for a very long print. [Nonnef] says the latest version took about 30 hours on his RepRap with a .35 mm nozzle. In the end nearly the entire Transformer came directly from a 3D printer, the only additional parts needed being a pen spring and a small screw. Paint is, of course, optional.
All the files are available on the Instructable.
We’re pretty sure they’re not canonizing alien robots, but this Optimus Prime stained glass sure looks good enough for a place at the local cathedral. It is [Kobachi’s] very first glass project, but we’d say he’s got a bright future ahead of him. Especially since it’s about ten times more complex than the assignment called for.
The design is based on artwork by [NinjaInkArt] called Optimus Noveau. It is included in the album linked above and shows Optimus with the matrix of leadership behind his head. This of course doubles as the halo you would find around the head of a saint in religious artwork. [Kobachi] started by simplifying the design into rough outlines and colors. He then split those outlines to make for easier cuts and then got down to business assembling the pane. It uses 121 different pieces and took him 80-100 hours to complete the work. We can’t wait to see the landscape follow-up showing Optimus as a semi truck.
If you’re not handy with colored glass you could try making this with colored circuit boards instead.
[shOOter—] and his family are just starting to keep chickens and need a coop in which the hens could roost. He wanted it to be mobile and protective and what is more mobile and protective and the leader of the Transformers? As you can see, his chicken coop is modeled after Optimus Prime.
The cab of the truck serves as the hen-house. It’s made of marine grade plywood held together with glue and galvanized nails. The exhaust stacks, which are made of PVC pipe, are not just decorative. They are chutes for the feed trays to either side of the blue ramp (you can’t really see the trays in this image). To give the chickens a way to stretch their legs he brought his welding skills to bear. The trailer portion of the build is a welded metal frame covered in mesh which provides a rather large exercise yard. Since the habitat is enclosed there’s really no need for an intricate motorized door.

A couple bucks worth of EL wire gives a nice green glow to [Mark Shasha’s] T400 Elite. Hopefully [Jeri Ellsworth] has some time to pull those how-to videos together so that we can make our own EL wire to replicate this hack.
This tiny cannon is right out of Night at the Museum. It works just like its much bigger brothers would; fill with powder, insert cannon ball, and light with a fuse. Both the introduction and the follow-up videos document the destruction of various objects using the diminutive weapon. [Thanks Thorsten]
Don’t close that browser
We use Google Chrome quite a bit because it tends to be more responsive when opening massive numbers of tabs while researching featured hacks. But there’s some things we don’t like about it. Lack of built-in PDF support under Ubuntu comes to mind, but a smaller thorn in our side is that closing the last tab will also close the browser window. [Ted Schaefer] got tired of the same thing so he wrote an extension called Last Tab Standing to trap that last browser tab, opening the default window instead of closing the browser.

Transformers balloon sculptures
If you’re having trouble finding that art piece to fill up your dining room you should consider building transformers out of balloons. The sculpture above is a free-standing Optimus Prime but the artist has also turned out Megatron, Grimlock, and others. [Thanks W01F]
