[Chris] sent us this project, where he built a tiny supercomputer called the Non-von1. Wanting a supercomputer, but lacking space and funds, he opted to go after the supercomputers of the 80s. His system was patterned after the “Von Neumann” systems developed at Columbia university. His system has 31 8 bit processors to crunch numbers for him. The whole unit communicates with the computer using a19.2 kbps serial link. He does talk about its limited capabilities, stating that he could use it as a way to store roughly half of his cell phone’s phonebook. This reminds us of the Basic stamp supercomputer we covered back in November.

VAIO P XP Install

Sony recently started to shipping the VAIO P don’t-call-it-a-netbook netbook. It comes stock with 2GB of RAM, which means it’s not eligible for Microsoft’s XP ultra low cost pc licensing. Hackers wanting to exorcise Vista have run into a few issues. After doing her unboxing photoshoot, [tnkgrl] wrote a guide for replacing Vista with XP on the Vaio P. She used the Universal Extractor to pop open the driver downloads and remove the Vista check. This got the WWAN radio and GPS working in XP. The only casualty was the volume and mute buttons are no longer working. You can see an annotated image verifying all the components here.

Punchy Punchout Controller

We love alternative inputs. They can revitalize an old classic or add a twist to most any mundane task. Here, we see a perfect example where the game Punch Out for the NES is being controlled by a punching bag type thing. The impact sensors were made by hand, and wired to a PC game pad. They were mounted on some foam, allowing for a nice mushy punching surface. There’s some feedback too, when your character is hit, a custom script detects the change in the sprites color and sends a signal to an Arduino. Right now, it just lights an LED, but the goal is to signal a strobe to make you flinch. This looks like it would be fun to play with, especially if you were to make it a little more high impact. You can see a video of them lightly assaulting it after the break.

N8VEM Single Board Z80 Computer

n8vem

The N8VEM is a homebrew computer project based on the classic Z80 microprocessor. It’s designed to be easy to build using large TTL DIP components instead of SMD devices. It runs the CP/M operating system and all drives are virtual in RAM/ROM. While the base hardware is interesting, we really like the potential for expansion using a backplane. Have a look at the project’s Hardware Overview to see extra boards like the bus monitor and the prototyping board. We found out about this project on [Oldbitcollector]’s blog; he’s using a Parallax Professional Development Board to create a VT100 terminal for the N8VEM.

Quick Robotic Base For Netbook

This is a great example of how marketing should be done. TeleToyland and RoboRealm(currently down) have teamed up together to show you how to build a quick and easy robot base for your netbook. The build process is fairly in depth, including part numbers and links to various places to buy them. They are using RoboRealm software to control the robot, utilizing two web cams for sensory input. This should get you well on your way to having an autonomous netbook wandering around your house.

Surviving A Hacker Conference

With another hacker conference looming in front of us, it’s time to start thinking about hardware security. Hacker conventions have the most hostile network you’ll ever encounter. [Security4all] points out that 25C3 already has an extensive page on securing your hardware. It starts from the ground up with physical security, BIOS passwords, and locking down bootloaders. There’s a section on securing your actual OS and session. Finally, they cover network usage. It mentions using SSH for dynamic forwarding, which we feel is a skill everyone should have. We’ve used it not just for security, but for bypassing brainless bandwidth restrictions too. There’s also the more trick transparent version. Every piece of data you bring with you, you risk losing, so they actually recommend just wiping your iPhone and other devices before attending. It’s important to remember that it’s not just your own data at risk, but everyone/thing you communicate with as well.

Multitouch MAME Cabinet

[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.
