Check out this really cool DIY on how to make a vertical wind turbine. This thing can produce some good amount of electricity for under $300.
With this one I am hoping to get the 100 watts.
Here is how I did it.
First we need: –5 pvc tube. size 3″X10′ (hardware store)$48
–3 bike wheels. size 12″ (junk yard or ask your kid to use their bikes for a minute) maybe $5
–Ametek38 volt (ebay or surplus store) $60 (a problem with ametek, it n
Check out the Robocut, a lawnmower robot with Basic Stamp as controller. You can even buy the kit so you can build one yourself.
Now, if you can get one of these DIY kits and make it solar, that’d be something to watch.
“RoboCut, is a BASIC Stamp powered robot. Two 12Volt motors with gearbox gives the two large drivewheels good traction and the robot can manouver in very small areas. Powersource is a NiMh accu-pack at 12V, 4.1 Ah. One motor gives the cutterdisk a rpm at approx. 3500 rpm. A Basic STAMP 2 is the brain in the PCB
For those of you Volkswagon-lovers or Golf-lovers (the car I mean), you are in luck as VW is working on a 105 horsepower, 184 lbs.-ft. of torque at a low 2,000 rpm diesel engine that could change the way you pump gas forever.

Let’s keep our fingers crossed so that this Golf gets to production.

I thought CNC machines were impressive, this one gets an extra star from me.
For these two videos I’m using a 1/16″ two flute slot cutter, the router is running at approx 35,000 Rpm, the additional battery on the to of the hex is a 12V NiMh 4500mah pack just to run the router. DXF files are loaded in to artcam where G-code tool paths are created. Due to the 10mm thickness of the poly and the cutter only being 6mm long, I chose to do two passes on the workpiece, th
Damn, this thing IS a beast! Crammed with a sizzling turbine jet, this jet boat will pollute the air like crazy yet it’s so cool!
This Turbine Jet-Boat is one fast ride. Looks like 1370 horse power is just enough for a wild water ski ride that you won’t forget.
“The T58-GE-8F turbine that is going in Squirt 2. It
