Shiny acrylic MAME box

This nice table-top MAME arcade features a two-toned acrylic case. [Fabricio] spent about 50-60 hours designing the 29 parts that make up the enclosure. Originally the sides were meant to be orange but one design flaw meant he had to have them recut and only had enough black stock for the job. But we like it this way. The screen is just over ten inches and inside you’ll find a mini-ITX motherboard with a gig of ram and a solid state drive. The seven page build log features some bending, glue, screwing, and wiring that really show off the depth of the project.
This results a very modern look but if you like your retro gaming to appear vintage we recommend this cocktail cabinet.

Pong, for real

Over at EvilMadScientistLaboratories.com they’ve asked a question that many of us have never thought to ask. What exactly is Pong supposed to be? Instead of assuming it was ping pong like the rest of us, they decided to build a literal physical interpretation. They may have taken some liberty, using solenoids as the paddles, but the end effect is quite nice. Watching them play actually looks both challenging and fun. There’s a great writeup about the construction, so be sure to check out the project page.

Hey man, you seen my turntable around here?

It’s all fine and dandy to have a turntable that sounds great, but [Mike] wanted one that looks great too. He build the transparent record player above and loved it for a little while. When his interest in it waned he built another, then several more. They all have some element of transparency to them, and each is a work of art. Makes us wonder how often he needs to dust his house to keep them looking so good.

Is turntable technology too advanced for your tastes? You can stick with your Edison cylinder, we won’t make fun.

[Thanks John]

Pinball build throws down the gauntlet

[Jeri Ellsworth] is building her own pinball machine. Her build log is delivered in the form of daily videos that walk through the progress. In addition to seeing the intricate ramps, traps, and controllers she outlines her build techniques. These include reproducing parts based on old pinball machines and bending acrylic with a custom tool or a toaster oven.

The driver she’s planning to use is an Altera FPGA with a bunch of FETs to control the heavy-load components. There’s not a ton of info on the actual electronics but we had a heck of a fun time looking at the creative field components. Our favorite by far is the television from Day 7. The screen is translucent with a rear projected image. When the ramp in front of it is raised the pinball can be jumped right through the screen!

We couldn’t find a project page for this but we’ve embedded [Jeri's] videos after the break. Read the rest of this entry »

Update: Realtime 3D for you too!

[Kyle McDonald] has kept himself busy working on 3D scanning in realtime. He’s posted a writeup that takes us through the concepts, tools, and assembly of a DIY 3d scanning camera. You should remember a preview of this method posted earlier this month, but now it’s time to build your own. You’ll need a camera, a projector, and some open source software to process the image data. Using these simple tools, [Kyle] turned out much better video than before. Take a look after the break to see his results from scanning at 60 fps using a PS3 Eye. The trick to this setup is getting the correct synchronization between the projector and the camera, something that could be improved with a bit of extra hacking.

Does [Kyle's] name sound familiar? It should, he’s got a long history of quality hacks that we’ve featured over the years. If you’re looking to use a scanner as a multitouch, add some music to tea time, or play with your skittles his work will give you a shove in the right direction.

Composite video output from chumby

[bunnie] posted this pretty slick way of getting composite video out of a Chumby. The Chumby is an open source connectivity device that has already seen some decent hacking. This modification, done by [xobs] isn’t too difficult. It only requires patching into some pads on the motherboard and loading a custom kernel to support the external output.

Fix a projector on the cheap

[j] sent in this nice writeup on how to revive a dead projector. he managed to pick one up for $20 that had a broken bulb. While the prices of bulbs have come down considerably, they can still be a couple hundred dollars. Being resourceful, he decide to just use a halogen bulb that he picked up at his local big box shop. In the photos, he’s using a 50w mr16 bulb. The results really aren’t too bad. Especially considering that his cost for the entire project is now roughly $25. He does, however suggest that a 100 watt bulb wouldn’t be a bad investment. His projector seems to need some cleaning and adjustment in the lenses as well, but for $25 it isn’t too shabby. We’ve had this submission for a bit, but it didn’t have any pictures of the projector actually working. During our conversation, we may have possibly suggested a picture we’d like to see. You can find it after the break.

We did cover a very similar one last year, which had the driver integrated into a custom bracket, but the project page seems to be gone. There is also the possibility that the projector you get doesn’t just have a bulb problem. Sometimes it is the polarizer that needs replaced.

Atmolight clone of an Ambilight clone

[Fun3] wasn’t satisfied with current methods for duplicating Philips Ambilight. He wanted a completely plug and play solution without soldering so he could expand upon it in the future. This meant Arduino, ShiftBright, and (it pains us to say this) pre-made cables. Some of you are cringing at the thought of no real ‘work’ being necessary, but remember, now this is much easier for your “I can’t change the VCRs clock” aunt to set up and enjoy. Plus it’s quick, easy, and most importantly – clean, something a lot of hackers have a problem with.

L2Ork – Virginia Tech Linux laptop orchestra

Create Digital Music Wrote a semi guide for Linux music creation and interaction after interviewing the L2Ork group. L2Ork is a Virginia Tech based Orchestra that use only laptops loaded with a custom Linux kernel, Wii remotes, and home built speaker salad bowls to produce some surprisingly amazing music. We’ve seen music creation from Wii Remotes before, but it didn’t sound anything like what L2Ork has created. The best part of the project, there are several videos and guides produced by L2Ork so you don’t have to attend Virginia Tech to produce your own music.

2600 game jukebox

[Yuppicide] sent us a link to a photo album of an Atari 2600 modified to play ROMs stored inside. We did some digging around and have an idea of what’s going on. It seems that the creator, [Victor] has taken his Atari 2600 cartridge emulator one step further.

Previously, he had replaced the chip in an Atari cartridge with an EEPROM that he could reprogram via a ribbon cable. This new iteration places that EEPROM inside the case of the gaming console along with a PIC development board. The PIC board interfaces an SD card with somewhere around 1200 ROMs on it. Three switches added to the front of the Atari allow the user to cycle through available games and flash the desired title to the EEPROM. As you can see, a 2×16 LCD display now resides in the cartridge opening.

This seems a little more eloquent (and less legal) than the Super Genintari.

[techknott]’s portable dreamcast

[Sydney] sent in this fantastic portable Dreamcast, built by [techknott], in response to the one we posted yesterday. While we agree, this one is much more polished, we want to point out why the post yesterday is more Hack A Day material. Sure, it looks more “hackish”, but that’s not what we are referring to. What we want to draw your attention to, is the lack of information. Yesterday, there was a build log. Today, there is not. Sure the other one could have had much much more information and we’re not commenting on which one is “better”. We’re just reminding you to please please please document your projects. Oh, and also, this thing is awesome.

Scan room, explore virtually

[Patrick] directed us to his project for alternate realism. The final goal is to be able to walk around in a space wearing a head mounted display, exploring a virtual representation of that space. This virtual representation could be altered, stylized, augmented and modified in countless ways. It is an exploration in perception, similar to enjoying different styles of painting, we could enjoy different styles of viewing a real space. Currently, it isn’t quite real time. He has to scan a room with a somewhat bulky device, then plug into his display to explore it. Being able to scan quickly and reliably enough shouldn’t be far off. [Patrick] notes that others have done almost real time scans at home already.

IntoDream, the ‘portable’ Dreamcast

What looks like an absolute mess of wires,5 fans,3 batteries, and other miscellaneous equipment squeezed into a Tupperware box on the left? At first we didn’t believe it, but it is actually [John's] fully functioning slick-looking portable Dreamcast on the right. The system runs Quake 3 for a little over 2 hours, not too bad considering it is also powering a VMU, rumble pad, 5 inch LCD screen, and did we mention 5 fans! All in all, it’s still smaller than the original Xbox controller, and we like that one of the greatest consoles is getting some well deserved respect. Check out the work log and a video of it functioning after the break. Read the rest of this entry »

Nunk on Droise

Nunk on Droise is an art installation where noise is made depending on how drunk you are. In a configuration that could be called a cthoilet, the sensors shown above are alcohol sensors. Though we initially thought this would be testing urine, the description states that it tests the breath of the participant. Unfortunately there aren’t any schematics or code, though you can see how it is all assembled from the flickr pool. You can also see a video demonstration of the prototype.

Bender keg cooler

What? Another Bender project? This almost went in the trash since it looks so much like the bender brewer from earlier this week, we thought it was the same tip. This isn’t a brewer though. This is a keg cooler, made to look like Bender. You can follow the build process to see exactly how they constructed it. They did a great job, the tap is in his cigar, and the keg resides in his body. Fantastic job guys, now you need some Benderbrau to dispense.

Complete the maze, get a gumball

This neat accelerometer controlled marble maze adds a level of fun to retrieving a gum ball. You have to first navigate the maze using a controller that has a dual axis accelerometer in it to control the angle of the platform. Though that does look like a wii accessory, there is no wiimote in there. Only after you have completed it will the gum ball machine dispense the candy. [Dan] constructed everything himself, which might explain the lack of “pits” for the marble to fall into in the maze.

More details on the build and source code are available on his page.

Omni-car

We stumbled onto one of [Nik Melton]’s projects, an Omni-car. It is omnidirectional, meaning it can go any direction at any time without having to turn. The body was designed by him, then printed with a 3D printer. The control scheme is what interests us though. He has found a simple way to wire it to get the job done. Sure you can see that it suffers from some pretty bad “drift” when trying to go in a straight line, but overall, we think he pulled it off well.

You might want to take a few moments to look around his project page. This guy has done a bunch of fun stuff like delta robots, strange hybrid wheel/leg robots, tesla coils, and arm mounted flamethrowers. Judging by the videos, he’s pretty young too. We think his guy has a bright future ahead of him.

Tauntaun costume

[Scott Holden] went all out this year and built an amazing Tauntaun costume. The Tauntaun from Star Wars was massive, standing 8 feet tall, and usually carrying a rider. [Scott] wanted to make it the correct size, and ultimately pulled it off. He had to build custom stilts to get the leg angle correct as drywall stilts were too straight. The rest is mainly pvc and fur. We think he did a fantastic job on this. The effect is quite nice, and we can imagine that in person it is even better.

Take note at the bottom of page 3. Apparently, he got pinned in the costume in his workshop and almost had to spend the night on the floor in the costume. That’s pretty wild, at least he was warm.

Biking through Google street view

[Aki] wanted to do some stationary cycling to get in shape. Unfortunately, his stationary cycle is located in his garage which doesn’t supply much inspiration or amusement. His solution was to build a VR rig so that he could ride around inside google street view. He has rigged a simple sensor to his wheel to determine his speed and he’s using a vuzix VR 920 as a display and orientation sensor. While he notes that it isn’t perfect, or even reliable, we think it is pretty cool. He can go sight-seeing, while getting in shape from his own garage. We have to wonder if he gets a headache after a while though.

Thingamawha? Thingamagoop2!

Introducing the Thingamagoop2! Remember that awkward looking box with two LEDacles sticking out and a bunch of strange buttons and knobs that with some circuit bending synthesized different sounds that kept your neighbor up for hours on end? Well now its back! Smaller and one less LEDacle, but jam-packed with more features – like our personal favorite: the ability to program it via Arduino. Check out a video of the ‘music’ after the break. Read the rest of this entry »
