Nice mod if you have an old Dreamcast laying around, Raph writes – “The image on a TV is always a little too blurry for my taste, and the quality of a VGA image is very superior. I had always dreamed to be able to use my SNES on a PC monitor, but the SNES did not have a VGA output. When I learned that the Dreamcast could output a VGA signal, I installed a VGA connector on it almost instantly.” [via] Link.
Tips for getting rid of the annoying hum – “Of all the annoyances that can afflict any audio/video home theater or even a simple stereo installation, the notorious “ground loop” may well be the most difficult and persistent one to track down and eliminate. A “ground loop” is caused by the difference in electrical potential at different grounding points in an audio/video system. (All the grounds in an A/V system should ideally be at “0” potential.) A ground loop typically adds a loud low-frequency hum or buzz as soon as you plug in any of various audio or video components, including subwoofers, cable-TV outboard boxes, satellite-TV feeds, TV displays, amplifiers, A/V receivers or turntables. The buzz/hum is a byproduct of the multiple power supply cables and a ground voltage differential within your system and its network of interconnecting cables.” Link.
Matt writes “Strangely aesthetically pleasing window blinds made out of junk mail. By affixing strips of junk mail to an existing set of venetian blinds, one can drastically reduce the amount of light allowed through without losing the ability to raise and lower the blinds. In my case, about three months’ worth of junk mail, but your mileage will vary. Your trusty roll of duct tape (color to suit). Two rolls of scotch tape. A ruler. A spool of uninsulated wire. A pair of needle-nosed pliers. A thumbtack. Space to work.” Link.
How to make the engine usually found in the BEAM solar roller – “…the most common use is in a solaroller which is a small wheeled car that charges up and then moves in a quick burst of speed. Since you can only use motors and coils with this circuit robots built with this circuit are mainly mechanical such as my artistic butterflies. One other common use is a little thing called a symet which can roam around and not get stuck using only one motor.” Link.
I think most of the online worlds will eventually swing this way – Multiverse is in beta “Make a complete Massively Multiplayer Online Game (MMOG) or virtual world for less money and in less time than you could have dreamed possible. Participate in the game industry’s most exciting frontier. Build the features that make your game unique, leveraging the expertise of the networking and infrastructure experts who helped build the web.

This is an incredibly cool, yet creepy panorama of a human head. I’d like to use this to make my Second Life avatar! “We’re trying to make high quality texture maps for game models. Using an FX-1 psuedo HD Sony camera, (its 1440 pixels, which is Sony’s anamorphic short-hand for a 1920 16:9 image,) placed sideways, I filmed Yoshi as he rotated on a turntable in front of the camera. The bank-robber cap was his idea. This resulted in about 1200 frames of a 360 degree pass around the head.” Thanks TowMater! Link.
If you’ve ever taken a spin on one of those theme park rides that show movies, shift/thrash the audience simulator-style you might like the idea of building your own. Jared, the Maker writes – “For some time I have wanted to make my own, seeing the NASA shuttle simulator and other similar training simulators all over. Well one day while playing mech 4 I realized that I had the power to do so literally in the palm of my hand. So I decided to mod out my simulator. Well a lot of R & D went into this and this is actually a prototype for the main build to come.” Link.
