Basic Kitchen Model CD Turbine and Magnetic Coupler.
This instructable will show how to make the experimental Kitchen Model Tesla CD Turbine, made from only CD's, CD Spindle, supermagnets, water nozzle and glue. Powered by faucet water pressure, this model Tesla CD Turbine can actually help with the meals and with family fun. (note: Experimenter's experience may vary...;)
A big plus is that the CD Turbine reuses CD's, millions of which get dumped into landfills, and take 200 years to break down. The Life Cycle of a CD is quite interesting; click here for a cool poster all about this.
The CD Turbine can also be a great way to re-use and re-cycle broken kitchen gadgets. For example, a blender or food processor may have a burned-out base motor. A perfect candidate! ( see step 6 & video).
It's amazing the number of fun games that can happen with a CD Turbine. Yes, it sounds nuts (even to me as I write this ;), but the CD Turbine can even put life into tired old board games! (see step 8 & video) I had a couple of dazzled kids earlier today who were mesmerized by the spinning spinner attachment for the turbine.
Building the basic Tesla CD Turbine has been described in my two previous Instructables.
This design, a Kitchen Model CD Turbine will differ in several areas, simplifying construction. This model is taller, giving a little more torque for tough kitchen jobs...(like salad spinning, blending, or having to stir a mixed drink; all examples I will show...hehe)
The taller size of this CD Turbine also recycles more old CD discs.
Punch Bowl Stirrer...(one heck of a punch...;)
Here is a video of my assistant Rowan using the Tesla CD Turbine as a cool Science Fair project.
Step 1: Materials and Tools
-25 CD's (or number to fit your spindle case.)
-CD Spindle, with Cover (one with a thicker base works best)
-Water Nozzle (such as the "Holland Garden House Plastic Power Nozzle")$1.29
-Hot-glue sticks - best ones you can find for plastics. ( about $3.00)
-Super glue and Marine Goop ( a couple of bucks worth)
-12 of 1/2 inch x 1/2 inch cylinder neodymium magnets
(6 for main Disc Pack, 6 for the Magnetic Coupler = 12 total at about $2.25 each = $ 26.80)
-132 of 1/32 inch thick x 3/8 inch neodymium magnets for magnetic disc pack spacers
(6 ea. x 22 discs = 132 magnets at $.019 each = about $25.00)
You can order the BEST neodymium super-magnets from K&J Magnetics here.
Total Cost of Materials less than $ 60.00 (Plus Accessories)
-Blender...........$1.50 Thrift Store
-Bowl................$1.00 Thrift Store
-Spinner...........$1.50 Dollar Store
-Salad Spinner.$5.00 Dollar Store
Total Cost of Accessories = $9.00
- Drill (optional)
- Knife (sometimes)
