HOW TO cool your home naturally
Keeping cool indoors when it is hot outdoors is a problem. The sun beating down on your home causes indoor temperatures to rise to uncomfortable levels. Air conditioning provides some relief. But the initial costs of installing an air conditioner and the electricity costs to run it can be high. In addition, conventional air conditioners use refrigerants made of chlorine compounds, suspected contributors to the depletion of the ozone layer and global warming. But there are alternatives to air conditioning. This article provides some common sense suggestions and low-cost retrofit options to help you “keep your cool” and save electricity. Link.
Here’s a cool picture of the moon, and how it was made (on the cheap)…So I came home today and stuck a cheap C90 Mak spotting scope onto my neglected Canon s400 4MP …together with a Universal Camera Adaper that I found online last week. Perfect fit. [
On a warm summerday, with 50 euro worth of helium in three balloons…aerial photography using digital cameras. The setup was relatively simpel: A 3.1 megapixel camera, hanging from three balloons (50-70cm). Total weight of the setup was somewhere around 450 gram, the balloons had a pull of about double that. Two threads of 100 meters connected the ballons to us, so that we could get the camera to land again [

Very detailed article (this goes well with the NES PC)…create your very own USB NES Controller. However, if you are not interested in HOW it is done and just want the HEX files and the schematic, you can skip to the end. 
Why is this NES PC better you ask? Well, first off I went with a real Intel MoBo/CPU (As apposed to the VIA EPIA all-in-one boards). I also installed a GeForce 2 MX video card to allow me to play recent 3D PC games! Lastly I wired up the front controller ports to allow me to use my original NES controller with an NES Emulator! And I did this internally! This means no ugly wires plugged into the back of the NES looping back inside the case!…
Politicians and automakers say a car that can both reduce greenhouse gases and free America from its reliance on foreign oil is years or even decades away. Ron Gremban says such a car is parked in his garage. It looks like a typical Toyota Prius hybrid, but in the trunk sits an 80-miles-per-gallon secret — a stack of 18 brick-sized batteries that boosts the car’s high mileage with an extra electrical charge so it can burn even less fuel. Gremban, an electrical engineer and committed environmentalist, spent several months and $3,000 tinkering with his car. [
