The people here at Hackaday aren’t dedicating their entire lives to moderating comments and sending press releases to the circular file; some of us actually have jobs and hobbies. [James Hobson] works at a projector company that was having a pumpkin carving contest today. He came up with the best possible use of a pumpkin projector – a R2D2-‘o-lantern that plays the message from [Leia] to [Obi-Wan Kenobi]. [James] submitted this to reddit, but one of the mods deleted it. We’re much cooler than a few mods and their little empire, so we’re putting it up here.
Instead of a knife, [James] used a rather interesting method for carving a pumpkin – a laser cutter. By maxing out the Z height of his laser cutter, he was able to cut a perfect R2D2 graphic on the surface of a pumpkin. No, [James] isn’t removing any of the pumpkin’s skin after the lasering is done, but the result still looks great when backlit.
Inside the pumpkin is a projector playing the famous distress message made from the captured Tantive IV. It’s not entirely accurate – [James] put the projector behind R2’s radar eye and not the holographic projectors, and to project [Leia] in mid-air he would need something like this, Still, it’s a great project we expect to see cloned a year or so from now.
Star Wars: Yoda Stories was released by LucasArts in 1997 to minimal critical acclaim. As IGN said, “like Phantom Menace proved, just because it’s Star Wars doesn’t mean it’s good.” This didn’t stop [Zach] from playing it, and years later, taking an interest in reverse engineering the game.
[Zach]’s reverse engineering of Star Wars: Yoda Stories (google cache) takes a look at the game’s data file. This binary file is parsed by the game at run time to extract sound effects, sprites, and map tiles. Perhaps the best known game data file type was Doom’s WAD file, which had purpose built editing programs from third parties.
After a quick look at the data file in HxD, [Zach] began writing scripts in C# to extract different sections of the data file. Once the sections were found, more code was used to apply a color palette and generate bitmaps.
In the end, [Zach] managed to get a couple thousand tiles of the game’s data. He found some interesting ones, such as the sports car that he replaced the X-Wing with in his mod. The engine for an earlier Lucasarts game, Indiana Jones and His Desktop Adventures, should be very similar, and once we find the Mac install disk and a copy of ResEdit, we’ll post something on Hackaday.io.
This full-size replica blaster from Star Wars, most iconically used by Han Solo and Princess Leia, has everything. Flashing LEDs, blaster noises, LEGO, and yes, even an Arduino. Not bad for [Baron von Brunk]’s first project to use an Arduino!
The blaster was based on electronics and LEGO that were lying around and was intended for use for Star Wars Day 2014. (May the Fourth be with you.) “Lying around” in this sense might be a bit of an understatement for [Baron von Brunk], as the design of the blaster required the use of the LEGO Digital Designer and 400 blocks, some of which are quite rare.
The electronics for the project are tied to a moving trigger mechanism (also made from LEGO). The trigger mechanism hits a momentary pushbutton which tells the Arduino to activate the LEDs and a separate 555 timer and sound recording/playback device which handles the classic blaster sounds. The whole thing is powered by a 9V battery and housed in the front of the blaster, and all of the code (and the LEGO schematics) are available on the project’s site.
This is quite an impressive replica, and the craftsmanship that went into the build shows, especially in the LEGO parts. We think Han Solo would indeed be proud! If you’re ready to go even further with Star Wars and LEGO, you might want to check out this barrel organ that plays the Star Wars theme.
We all know the scene, Obi-Wan Kenobi gives Luke a helmet with the blast shield down. He tells Luke “Your eyes can deceive you. Don’t trust them. Stretch out with your feelings!” Easy for Obi-Wan to say – he doesn’t have a remote training droid flying around and shooting at him. [Roeland] and his team are working to create a real-life version of the training droid for Hackday’s Sci-Fi contest.
The training droid in Star Wars may not have had the Force on its side, but it was pretty darn agile in the air. To replicate this, the team started with a standard Walkera Ladybird micro quadcopter. It would have been simple to have a human controlling the drone-turned-droid, but [Roeland and co] wanted a fully computer controlled system. The Ladybird can carry a small payload, but it just doesn’t have the power to lift a computer and sensor suite. The team took a note from the GRASP Lab and used an external computer with a camera to control their droid.
Rather than the expensive motion capture system used by the big labs, the team used a pair of Wii Remote controllers for stereo vision. A small IR LED mounted atop the droid made it visible to the Wii Remotes’ cameras. A laptop was employed to calculate the current position of the droid. With the current and desired positions known, the laptop calculated and sent commands to an Arduino, which then translated them for the droid’s controller.
Nice work guys! Now you just have to add the blaster emitters to it!

[Jedii72] needed a power supply. A quick search online revealed many instructions for building one out of an old ATX power supply, but — he didn’t want just any kind of power supply — he wanted to build an AT-ATX.
He started with a vintage AT-AT toy from the 80’s, and then began cutting it into pieces.
Hold for gasps of disbelief. Don’t worry though — it was in poor condition to start with, so it was never really considered a collectible. After cleaning over 30 years of grime and dirt off the toy, he gave it a fresh coat of jet black paint — not exactly canon, but it does look pretty awesome. You know, it would make a pretty awesome Sci-Fi contest entry, don’t you agree? Continue reading “An AT-ATX: A Different Kind of Power Supply”
It’s no secret that [Adam Savage] of Mythbusters fame is a huge fan of replica props, going so far as to make a Maltese Falcon out of Sculpey. This time, though, he’s doing one better for the nerds in the crowd by building the most accurate replica of Han Solo’s blaster ever.
Replica prop gurus already know [Lucas]’ original prop department based Han Solo’s BlasTech DL-44 blaster off an existing gun – the Mauser C96. Along with this gun, there were a few extra bits and bobs tacked onto this gun, including an old German scope, a flash hider from an aircraft machine gun, and even a few bits of metal from a model airplane.
All these extra parts and greeblies are very hard, if not impossible to find. Thankfully, there are a bunch of very skilled replica prop makers reproducing these parts for anyone who wants a very accurate DL-44 Blaster. [Norm] from Tested and [Adam] assembled these parts into an incredibly accurate replica of the ‘hero’ blaster – by far the most identifiable of Solo’s many iterations of blaster seen in Star Wars ep. IV.
As all 6-year-olds should, [Marc]’s son is a huge fan of Star Wars. For his birthday party, he wanted a Star Wars themed cake, and making one in the shape of R2D2 seemed to be right up [Marc]’s alley. Of course any clone of everyone’s favorite R2 unit should also display Leia’s distress message to Ben Kenobi, and [Marc] figured out a way to do just that.
Because of R2’s strange and decidedly non-cake shape, [Marc] first constructed a stand out of wood, cardboard, and a PVC pipe to hold the cake into place. The cylindrical droid body is of course made of cake and frosting, with R2’s dome made out of fondant.
The PVC pipe running up the center of the droid provided [Marc] with the ability to run a power and video connector up R2’s spine. These are connected to a small projector receiving video from a netbook placed out of the way.
You can check out a video of the R2 cake playing Leia’s holographic distress message below. At the end of the video, there’s a 6-year-old birthday party guest saying, “what is that?” It might be time to dig out the VHS player and the non-remastered trilogy, [Marc].
