This is a mini sized 3d printable mobile robot platform.

the robot travels on a standard 7 spd bicycle chain.




The P.K.E. Meter (also known as Aurascope) was one of the Ghostbusters’ tools invented by Dr. Egon Spengler that enabled them to track ghosts and other entities.
The full name of the device is a Psychokinetic Energy Meter, so named because its function is to detect the amounts of said energy and to direct the user to its location.
The design of the device is a small screen, mounted on a handle, which has a pair of sensor ‘wings’ protruding from either side. These wings have lights along their length, and will flash and extend as the meter closes in on the source of a P.K.E. signature. Much like a metaphysical Dowsing Rod, the meter will begin to buzz more and more in response to approaching a source of P.K. Energy. Once at the source of the energy, the wings will extend to their fullest length and the meter will buzz noticeably at a higher pitch.

As the name implies, here is a PKE METER design similar to the one in the movie; Ghost Busters. Print this and use it to complete your ghost busters prop set or costume. Being a designer, I’ve improved the design a bit, so this PKE meter is not %100 same with the one in the movie, a bit smaller to fit smaller printers, better buttons and minor changes at the details. Internals should be quite different as i’ve never seen the inside of the original. 😀

I like retro games, especially retro game consoles. When i was a kid, one of our neighbour’s who used to work in abroad, used to bring his son electromechanic portable game devices or consoles I remember. We also queu up as the other kids to have our chance to play with the games. They were interesting, nearly nothing electronic or solid state inside, everything working with gears, wires, dc motors, lamps (not leds) and some color filters for creating screen effects.
I sketched several similar console designs on paper first. Selected one of them which would be easier to design, 3d print and assemble then started working in solidworks.
took me a short while to3d model the main form and a bit longer to model the components and interior assembly details.
