Sustainable technology PDFs

91Cover Chris writes “Selected articles from past issues of ReNew magazine (sustainable technology – lots of DIY/MAKE-type articles). Of interest in light of recent blog entries see “Issue 83: Biodiesel on the farm – One Victorian farmer is running all his vehicles and machinery on biodiesel he makes from his own oilseed crop. He even supplies his own biodiesel recipe tips.” I’ll be reading a lot of these! Link.

VGA over Cat-5 cable

VGA over Cat-5 cable

Hd15Torj45 I need to try this to confirm it works…It’s possible to send a VGA “video” signal down an ordinary Cat-5 ethernet cable. This is possible for two reasons: firstly, although VGA connectors have 15 (or 13) pins, only about 8 wires are actually necessary to send the VGA signal; and secondly, ethernet cable is twisted pair, and we can use the magic of twisted pair to push the analog VGA signal further than spec.

Bicycle frame building

Bicycle frame building

Bb-Downtube Great resource. Bicycle frame building has a reputation as being an arcane art; something that’s practiced by wizened old Jedi masters, or else carried out by huge, complicated robots in Taiwan, attended by a small army of engineers, technicians, and metallurgists. This isn’t so. Frame building is a craft like any other, with simple, consistent rules that mere mortals can master fairly easily, given sufficient attention to detail and care. [via] Link.

DIY CD Lamp

DIY CD Lamp

Cds Sm Great use for all those old CDs laying around, make a lamp! At a previous job, the head of QA had several stacks of several hundred CDs on the floor in front of floor to ceiling windows. The sunlight shining through the window would glow through these CDs in a very appealing manner that made the green light seam warm. From that point forward I always thought that a stack of CDs with a tubular light inside would make a very cool lamp. [via] Link.
