I’m One Step Closer To Azeroth

While looking for a way to injure his neck and live in the World of Warcraft all at once, [Gavan Woolery] came up with the idea for this virtual reality setup. That monitor, residing just inches from his eyes, is putting out 1080p at 120Hz. His plan is to pair up the motion sensing seen in the video after the break with an NVIDIA 3D Vision Kit for something close to total immersion.

To be fair, [Gavan] never mentions WoW, but we all know where this is going right?

How-to: Make A Mains Crossover Cable

Update: This How-To was written for April Fools’ Day. It is not advisedĀ  you attempt to make or even use this cable. The comments have made it very clear how dangerous to you and others using this cable can be. The image above is not of a full male-to-male cable, only the ground is connected, and the generator is not running.

We all know Ethernet has the crossover cable, cars have jumper cables, and RS232 has the null modem. Well, it is about time our wall sockets get their own crossover cable. This crossover cable is great for running power to a circuit disconnected from power. Maybe you are out of fuses, the breaker is broken or you just don’t want to go check the fuse box when there is a murderer about. This cable makes a great gift for even the most loathsome of acquaintances. Continue reading “How-to: Make A Mains Crossover Cable”

Core3Duino (April Fools?!) And XDuino

It’s inevitable. You knew it, we knew it, and while this is being posted on April 1st; its no joke. [johndavid400’s] Core3Duino. As we mentioned before, with the additional Arduinos you have now 3 separate processors, allowing 24digital IO, 18 PWM, 18 analog inputs, and more.

Now to keep flamers at bay (calm down), we’ve combined this post with the introduction of xDuino. Yet another attempt at porting Arduino to separate hardware platforms. For the price of a Duemilanove you can have 5 serial, 48 IO, 18 analog, 68Kbytes of Ram and more!

CNC Plotter From Old Parts

[vimeo=http://vimeo.com/10479779]

Get a quick fix of CNC for the day with this plotter. [Francisco Dulanto] grabbed the cartridge carriage from an old inkjet printer and turned it into a gantry by mounting it on two drawer sliders. The optical head assembly from a cd-rom provides the Z-axis movement with the whole thing controlled by three RepRap boards. [Francisco] called his project a joke compared to the Turing Machine, but we like it and we’re glad he tipped us off. There’s something zen-like about the projects that are thrown together with what you have available. After all, he’s certainly achieve a clean-looking build that does what it’s intended to do.

Sony Removes PS3 Linux Support With An Update… Errrrr, Downgrade?

Sony is rolling out a firmware update for the PS3 on April 1 but we’re pretty sure it’s not a joke. What we’re not sure about is that you can call it an update. It removes features rather than fixing or adding them. In this case, it is removing the “Install Other OS” option that allows you to run Linux on non-slim versions of the PlayStation 3. It is fairly obvious that this is a reaction to the hypervisor exploit that was released back in January that breaks down the machine’s security barriers.

[Geohot], the guy who found and release the exploit, published a post on his blog expressing his disapproval of Sony’s actions. We’d have to agree. It’s pretty cold-hearted to remove functionality that was advertised with a product. We’re sure there are many folks out there using the Linux support who have no interest in exploiting the product. This is gardening with a backhoe and quite frankly it stinks.

This may bring on a torrent of new effort in unlocking and laying bare the PS3. If so, doesn’t Sony deserve it?

Home Fabricated Boards In Any Color

Tired of every printed circuit board you etch coming out brown? Take a page out of [Dane’s] book and dye your PCB to just about any color you want. One hour submerged in a 200 degree bath of Rit dye turned his brown FR4 substrate to the desired dark green. We give him points for being dangerous enough to use a broken bottle as a vessel, yet wearing eye protection at the same time.

We never really thought of doing this, but it’s pretty interesting that it works. We’ve stained the substrate when removing etch resist so this should have been obvious, but wasn’t.

Update: 50MHz To 100Mhz Scope Conversion

Changing this 50MHz Rigol oscilloscope into its larger, more expensive brother just became quite a bit easier. When we originally looked at this hack it required pulling some capacitors off of the board. Now all it takes is three commands over a serial terminal connection.

Take a look at the walk through video after the break. You’ll see that there’s one chip that needs to be setup differently to change the functionality. Removing capacitors was actually changing the commands sent to initialize that chip at power-up. Now you can just change the model number and one letter of the serial number via a terminal and the firmware will recognize this as the more expensive DS1102E.
