If you have one more dead hard drive left after building the top five dead hard drive projects give the Hard Drive Platter Tesla Turbine a try. There is more information about the build at Instructables.
“In the Tesla Turbine, air, steam, oil, or any other fluid is injected at the edge of a series of smooth parallel disks. The fluid spirals inwards and is exhausted through ventilation ports near the center of the disks.
A regular blade turbine operates by transferring kinetic energy from the moving fluid to the turbine fan blades. In the Tesla Turbine, the kinetic energy transfer to the edges of the thin platters is very small. Instead, it uses the boundary layer effect, i.e. adhesion between the moving fluid and the rigid disk. This is the same effect that causes drag on airplanes.
To build a turbine like this, you need some dead hard drives, some stock material (aluminum, acrylic), a milling machine with a rotary table, and a lathe with a 4 jaw chuck.”

hi, how can i get the plans to build my own rotary engine?

When I read the actual patents of Tesla on the turbines, the inlet port is in the center. Look for yourself. I wonder if it works differently if run the way the inventer described.

Regarding Bob B.’s “the inlet port is in the center”:
1) With the inlet port in the center, apply rotary power to the shaft to use the device as a pump.
2) With the inlet port at the edge and exhaust at center, apply pressurized fluid to use the device as an engine that turns the shaft.

What Robbo said, that is correct. I don’t know about you others, but those polished disks look very much like disks taken from a used hard disk memory. Disassemble one and see what I mean.
