Mac Tablet Keeps The Look Of The Donor-Macbook

October 1, 2010 by Mike Szczys 15 Comments

[Enigma-penguin] built a tablet computer out of a Core2Duo Macbook circa 2007. The battery exploded, damaging the case and a few components inside. But there was hope for a new life as a tablet computer. He removed the screen and tested to make sure the computer would still function without it by using the video out port.

Putting the whole thing back together as a tablet proved to have some headaches. He worked through problems caused by the addition of a touchscreen between the LCD and the bezel and made the connections work with the screen flipped. The finished product looks so good because the bezel has not been turned around like on other tablet builds. Instead, a viewing window was cut in what would have been the case behind the screen.

There’s a little more to be done yet. The black USB cable seen above is the connector for the touchscreen which he plans to internalize. The magnetic sleep sensor has been relocated to the headphone jack. Inserting a plug (no cord necessary) puts it to sleep for transport. There’s also an on screen keyboard and the ability to change the screen orientation from landscape to portrait. After the break we’ve embedded one of [Enigma-penguin’s] demonstrations.

Build A Cutting Laser From An Old PC

September 30, 2010 by Mike Szczys 75 Comments

[Drake Anthony] makes building a cutting laser from a PC look easy, and it seems like it actually is. Almost everything you need can be found in a dead desktop unit. The diode is pulled from a DVD writer (16x or faster), with the power supply unit, and heat sinks from the processor and GPU being used as well. You’ll also need a focusing lens (just a few dollars), some thermal glue, an LM317, a resistor, and a pair of protective goggles matching the laser diode’s wavelength.

He fits the diode into the lens, then glues the assembly into a hole drilled through the processor heat sink. A driver is built using the LM317 variable regulator, resistor, power supply, and the GPU heat sink to keep things cool. Check out the video after the break to see the laser cutting tape, burning plastic, and lighting matches. Continue reading “Build A Cutting Laser From An Old PC” →

Printing From A Famicom Clone Computer

September 30, 2010 by Mike Szczys 14 Comments

This is an 8-bit computer and Famicom clone that [133MHz] bought for $2. It plays Nintendo games and using an 80-in-1 cartridge it has a rudimentary operating system and set of applications. Seeing a standard DB25 port on the back [133MHz] wondered if he could make the system talk to a printer. His first step was to investigate the electronics inside to find that the connector has a couple of chips that map to the data bus of the CPU and use the same control lines as the cartridge. That means it can be setup to do just about anything in software. After a bit of coding he’s got it printing to a dot-matrix. See for yourself after the break.

The New Apple TV

September 30, 2010 by Mike Szczys 38 Comments

You’ve probably already heard about the Apple TV 2. It retails for $99 and packs a punch with HD video, optical audio, and WiFi in that tiny package. But as always, we like it for its hackability. Even though it’s just starting to ship, the hacks are already rolling in. The firmware is available from Apple’s servers and has already been unlocked with the yet-to-be-release SHAtter exploit. [Das_coach] even sent us a link to a video of the new Frontrow ported for the iPod touch (embedded after the break).

But the holy grail has to be XBMC. We’ve seen it on the first generation Apple TV and it was good. The second generation switches to the A4 processor which is an ARM Cortex-A8. Not quite as easy to port for as the Intel chip on the first generation was. But there is hope, one of the 2010 Google Summer of Code projects worked to port XBMC to another ARM device, it’s just a matter of inspiring some developers to take on the quest to make it happen. We can’t wait for the day that we can just velcro one of these to the back of our TV and be done with it, that first generation Xbox isn’t going to last forever.

USB Mouse With Storage Added

September 30, 2010 by Mike Szczys 31 Comments

[Thice] wanted to try his hand at incorporating a USB driving into other devices. He chose to add storage to his USB mouse but didn’t want to alter the factory look provided by a color-changing LED inside. To make things fit he ended up cutting a good portion of a USB hub’s circuit board off and placing it beneath the mouse circuitry. You can see the board from the thumb drive wedged into one end of the case in the image above.

He sees this as a way of hiding data in plain sight. This is true, and it’s along the same lines we’ve seen before with a WiFi dongle in a mouse, or the thumbdrive in a controller hacks. To be truly hidden we’d like to see someone incorporate a microcontroller that monitors the mouse buttons for a certain code, and then toggles the voltage to the USB storage. This would simulate plugging and unplugging the drive, hiding it virtually as well as physically.

Dazzling Coat Sure To Be In Demand With Pimps Everywhere

September 30, 2010 by Mike Szczys 37 Comments

This is the newest addition to [Arren Parker’s] Burning Man wardrobe. The full-length lighted faux-fur coats is completely his creation. He started with a pattern that he acquired from Ebay, adding side pockets and changing the hood to a collar. From there he added the 256 RGB LEDs that make it shimmer so appealingly.

For this to work, he designed and ordered 300 tiny PCBs on which a connector socket and the LED are soldered. These are driven by a set of six TLC5940 pulse-width modulation chips, and ultimately by an Arduino. The effect is spectacular (see for yourself after the break), and we’re sure it’ll be a hit at burning man. Continue reading “Dazzling Coat Sure To Be In Demand With Pimps Everywhere” →

Dreamcast VMU, Meet IPod

September 29, 2010 by Mike Szczys 55 Comments

We’d bet you never had a Dreamcast Visual Memory Unit, but if you can find one now it can be turned into an iPod (translated). The VMU was originally a memory card for the not-so-popular gaming console that put an LCD screen right in your controller. When you weren’t at home you could take it with you and play mini-games. This version lacks its original guts, which have been replaced with a 6th generation iPod nano. The screen is just a bit small for the opening so a frame of white tape was applied as a bezel. The sleep button has been extended through the cover for the VMU connector. It seems there’s a gaping hole in the back of the case, but after seeing the ultrasonic knife used to cut away the plastic we don’t care. We’ve embedded video of that tool after the break.
