Multitouch MAME Cabinet

December 24, 2008 by 19 Comments

[rdagger] sent us this really well done multitouch MAME cabinet build. He ha penned to find a used, and fairly worn cocktail cabinet. The monitor was damaged, keys lost, and internals had been home to mice for some time. He promptly tore out the old guts, replaced the smelly mouse damaged base and began building the projection system. For touch sensing, he’s using a web cam with the IR filter removed to detect disturbances in some IR laser beams. We’re not completely clear on how he mounted the lasers, he skips over that part.  There’s nothing groundbreaking in the technology here, we’ve done multitouch many times before. This project stands out in its execution. [rdagger] has done a fantastic job, the construction looks fantastic.  Check out a video of it working after the break.

WAP Controlled Home Automation

December 22, 2008 by 8 Comments

[Josh] sent in a home automation project he did a little while ago. It has a total of eight switched outlets. The main focus of the project was WAP access for remote control from any cellphone. The control box is based on a design by [Ashley Roll] for controlling eight servos using a PIC microcontroller. A listener app written in Java monitors the control web page and sends signals to the board via serial port. He used opto-isolated 240V solid state relays for each of the outlets. All the pieces are available on the site and he might even do a custom control board design if there is enough interest.

No Solder EEEPC 701 Upgrades

[luke] has put together a set of EeePC upgrade instructions for those who suffer from solderphobia. If you have the EeePC 700 or 701,  also known as the 4G surf, you can upgrade the storage, add bluetooth, and a touch screen without having to solder a thing. Those models don’t have the built in camera, so they have an unused internal USB port.  With some crafty taping and careful placement, you can upgrade as easily as [luke]. We’ve really seen the EeePC mature, the product line has expanded quite a lot. For those who don’t mind a little solder, there have been tons of hacks for the EeePC.

Securing Your Data

December 20, 2008 by 6 Comments

Lifehacker has published an overview of some of the many ways you can secure your data. The post was prompted by recently released browser vulnerabilities: first IE, then Firefox. They cover techniques far beyond just browser security, like how to properly wipe your iPhone. They mention disk encryption go-to TrueCrypt along with password management tools like KeePass. They also suggest using temporary credit cards to mitigate the impact of fraud.

Netbooks, Slow Thanks To Microsoft

[nico] pointed out something that didn’t seem to get any air-time during the recent netbook kerfuffle. Part of the original TechCrunch complaint was that netbooks are underpowered. This is a direct result of Microsoft’s Ultra Low Cost PC (ULCPC) licensing program. If manufacturer’s don’t stick to Microsoft’s restrictions, they can’t purchase XP at a discount ($26-32), which is the only way to get XP since they no longer sell it. These rules are why you can’t buy a netbook with more that 1GB of RAM.

Sony Vaio UX 64GB Solid State Upgrade

December 16, 2008 by 26 Comments

This Sony Vaio UX50 came with a 30GB hard drive from the factory. This hacker wanted to do an upgrade and move to solid state, so he started hacking away. He ended up with a total of 64GB of solid state storage crammed into the computer.  The hard drive was replaced with a 4GB compact flash drive and the rest is spread through out the device. Apparently any crevice or crack in the Sony UX50 can have memory shoved into it. He managed to somehow get 60GB of storage in there through various USB extensions and adapters. Notice the sticker on the inside of the case. Is this the latest fad? Decorating the inside of the unit where only you know it exists?
