Here’s a great DIY on how to make a solar heater. Although the one he made is not functional you can probably easily make it functional by adding an inlet pipe and outlet pipe plus a small PC fan. But the theory is very impressive and this thing could be made more efficient with a little bit more work.
Using the same equipment and methods, I determined the outlet temperature to be about 95 degrees - thus a 15 degree temperature differential. Not 110 degrees, but not bad , considering I didn’t even break $50 in materials - most of that being the plexiglas window.
Obviously don’t have the inlet and outlet attached to the garage - figures that the day I finish the furnace, it’s 80 degrees and sunny and it looks like we’re finally done with winter. Dad recommends wiring a pusher fan at the end of the inlet tube to keep the air circulating through the furnace.

Here’s a cool simple DIY on how to make a noise-free headphone without spending $349 on brand new Bose QuietComfort 3 Noise cancelling headphones.
These home-made hifi headphones work as well or better than Sony or Bose noise-cancelling headphones.
Cost: $20
Time to make: one minute.
Difficulty: none.
As seen in my article in Make Magazine volume 5
Unlike the commercial products, these block outside noise instead of cancelling it.
Listen to music or books on tape without hearing traffic noise, screaming babies, etc.
I’ve been making these for more than a decade. People sometimes ask “isn’t it dangerous not being able to hear?” No. Talking on a cellphone shuts off most of the brain whereas listening to headphones is no more dangerous than say, being deaf.
Lots of my friends use these units and no harm has come to anyone.

Check out the Dutch Design Home PC! Looks really cool.
“Our idea was to create something small, stylish and quiet and we asked the Dutch designer Ed Annink to make the design.
The case is built around one layer aluminum heatsink to provide cooling surface for the hard disk and other components.
And the cover of the case is fully fitted with highly efficient noise absorption material to get rid of any unwanted sounds.
The Psile case is constructed out of 0.16 inch aluminum and the surface has been given a sand-spray finish.

Wow, check out this awesome window shade that also acts as a solar powered light!
This is a continuation of a project from Design for the 5 Senses that I worked on with Michael Jefferson and Jae In Lee. It’s a window shade that doubles as a light. One set of strings would be to control the level of sunlight by adjusting the height of the shade. The other set of strings controls the light level. I didn’t have time to add a solar component to it for that class, so I decided to work on this for Advanced Tech. There is some general “design” info here and a list of resources, but this page is mainly tech documentation of the solar component. Please see links on the left for more background & project info and images.
