Xbox 360 Slim Gets Gutted And… Painted White?

XBox in a Briefcase

We love portable console builds, and this one by [Daniel Fürstauer] is no exception. It’s a beautifully hacked Xbox 360 slim into an aluminum briefcase — complete with a screen and a full audio system!

He started by gutting the Xbox 360 slim and throwing out pretty much all of the original enclosure, minus the disc drive cover. Now what he did next was completely for aesthetics, but freaking awesome. He actually took the motherboard out, taped off some of the important components, and spray painted the entire thing white! We’re not too sure what effect this will have on some of the components, but it seems to work, and gives it a really unique look underneath his Plexiglas enclosure.

He housed the rest of it (complete with custom cooling fans!) inside of one of those nice aluminum briefcases, complete with a widescreen LCD monitor, and computer speakers. He even fit the power supply inside — all you have to do is plug it in! There’s also room for at least one controller, whose holding spot doubles as space for the disc drive to eject.

Make That C64 Keyboard Work As A USB Keyboard

July 17, 2014 by Mike Szczys 25 Comments

keyboard-to-usb-mapping

Let’s face it, we all have keyboard peculiarities. Don’t try to deny it, everyone who types a lot has an opinion of the keyboard they stroke so frequently. We know [Brian Benchoff] swears by his model M, and we’re guessing he was the one that bumped into [Evan] and convinced him to write about his conversion of a Commodore 64 keyboard for use as a USB device.

This is not [Evan’s] first rodeo. We recently saw him fixing up the worn off letters of his own model M. But this time around there’s some clever microcontroller work at play. Apparently mapping 122 keys using an Atmel AVR 32u4 chip (built in USB connectivity) is quite a task. Luckily someone’s already worked out all kinds of good things and is sharing the love with the Soarer’s Keyboard Controller Firmware. Of course it handles scanning, but also includes debounce, muxing, and the trick to scan more keys than the uC has pins for. We still don’t fully understand that bit of it. But [Evan] did post the config file he’s using so perhaps after we get elbow-deep in the code we’ll have a better understanding.

If you give this a try, we want to hear about it. Anyone have any modern keyboards they’re in love with? Leave a comment below.

Marvin’s Marvelous Mechanical Museum

July 17, 2014 by Mike Szczys 9 Comments

Don’t call it an arcade. There are arcade-like things about it… like dance-based video games, Skee-ball, and tickets — oh so many tickets. But Marvin’s Marvelous Mechanical Museum is a one-of-a-kind that you need to visit next time you’re in the North suburbs of Detroit, Michigan.

[Marvin] was there in person, as he is many days. He talked with us for a few minutes and we’ve folded his interview, along with footage of many of the attractions, into the video above.

He’s been collecting for more than three decades. The attractions are packed into every bit of floor space, spilling up onto the walls, and hanging from every spot in the ceiling. There are true antiques from both home and abroad that could be referred to as automatons, rows of fortune tellers, a track of large airplane models that make a loop around the establishment when fed a quarter, and much more.

Some of the attractions were build for him, like the robot band you can make out behind [Marvin] during the interview. It is a MIDI-based build that allows songs to be selected from a touchscreen. Soon to be on exhibit is a Tesla-coil-based offering which [Marvin] commissioned after taking second place to [Nicolai Tesla] on a list of oddest museums.

A Lithium Ion Supercapacitor Battery

July 17, 2014 by Brian Benchoff 139 Comments

lioncap Lithium ion supercapacitors. No, not lithium ion batteries, and yes, they’re a real thing. While they’re astonishingly expensive per Farad, they are extremely small and used as the first line of defense in some seriously expensive heavy-duty UPS installations. Here’s a Kickstarter using these supercaps to replace the common AA, C, and D cell batteries. Even better, they can be recharged in seconds.

For each size battery, the caps used actually have a slightly higher energy density than a similarly sized dollar store battery. By adding a little bit of circuitry to drop the 3.8 Volts out of the cap down to the 1.5 V you expect from a battery, this supercap becomes a very expensive rechargeable battery, but one that can be recharged in seconds.

This is one of those crowdfunding campaigns we really like: an interesting tool, but something we just can’t figure out what the use case would be. These lithium ion supercaps are too expensive to be practical in anything we would build (save for a Gauss pistol), but the tech is just too cool to ignore. If you have a use case for these caps in mind, please leave a note in the comments.

Building The Slimmest Raspi

July 17, 2014 by Brian Benchoff 28 Comments

slim_pi

[Colin], AKA [Domipheus], was working on a project to monitor a thermostat with a wall mounted Raspberry Pi and a touchscreen. Simple enough, but the Pi has a problem: The plugs are all around the perimeter of the board, and with a TFT touch screen shield, it’s a bit too thick to be wall mounted. What followed is a hack in the purest sense: [Domipheus] removed and relocated components on the Pi until the entire Pi/display stack was just a hair over 10mm tall.

A Raspberry Pi Model A was used for this build, meaning the Ethernet jack was gone, and there was only a single USB port to deal with. Still, the highest components – the RCA and audio jacks – were too tall and needed to be removed; they weren’t going to be used anyway.

After these components were gone, [Domipheus] turned his attention to the next tallest parts on the board: fuses, caps, and the HDMI port. For fear of damaging the surrounding components when removing the HDMI connector the right way, this part was simply hacked off. The large tantalum cap near the USB power connector was removed (it’s just a filter cap) and the large protection diode was moved elsewhere.

Slimming down a Pi is no good without a display, and for that [Domipheus] used this touchscreen thing from Adafruit. Things got a little complicated when the project required the ability to remove the LCD, but you can do amazing things with a DIP socket and a file.

The end result is a Raspberry Pi with touchscreen display that’s just a smidgen thicker than a CD case. It’ll fit right up against a wall in its repurposed enclosure, and the end result looks very professional.

THP Hacker Bio: Hackersbench

July 17, 2014 by Mike Szczys 19 Comments

Remote sensing applications that make sense and cents? (sorry, couldn’t help ourselves) That’s what [hackersbench], aka [John Schuch], aka [@JohnS_AZ] is working on as his entry for The Hackaday Prize.

He received a multi-thousand-dollar water bill after having an underground pipe break and leak without knowing it. His idea will help you notice problems like this sooner. But if you actually have a way to capture data about your own water use you also have a tool to help encourage less wasteful water use habits. We wanted to learn more about the hacker who is working on this project. [John’s] answers to our slate of questions are after the break.

Developed On Hackaday: Discovering Shenzhen And Its Companies

July 17, 2014 by Mathieu Stephan 21 Comments

Two weeks ago we showed a first demonstration video of the offline password keeper (aka Mooltipass) the Hackaday community had been working on for the last 6 months. We received lots of interesting feedback from our dear readers and around a thousand of them let us know they were interested in purchasing the device. We agreed that preferential pricing should be offered to them, as they have been supporting this community driven project for so long.

For the next few days I will be touring Shenzhen and finally meeting the persons who have been assembling my electronics projects for the last 2 years, including the Mooltipass beta testers’ batch. I’ll also meet with Ian from Dangerous Prototypes, talk with the people behind the Haxlr8r program, visit Seeedstudio offices and a CNC shop. If everything goes well with the camera I just purchased in Hong Kong I should have nice things to show you. In the meantime, don’t hesitate to leave a comment below in case you’re in the area…
