Escher’s “Relativity” in LEGO! “…our fourth Escher picture rendered in LEGO. Once again, no camera tricks, but the picture has to be taken from exactly the right place, and boy did we get tired of trying to find where that place was. The whole thing took five or six evenings spread over two or three weeks. Most of the last evening was taken up with setting up the lighting the way we wanted it and trying to get the camera position just right…” Thanks Techhat! Link.
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.
