MindPi - Version 1

A simple way to directly connect the Raspberry Pi and the Lego Mindstorms Ev3.


2 Computers - Raspberry Pi and Mindstorms Ev3
53 Lines of Python
42 Mindstorms Blocks

Why I Built It?
About four or five months ago as a gift a received a Raspberry Pi, I was appropriately great full but wished it was Lego! ) : I set it up played the Pi Craft or whatever that thing is called but got board in around fifteen minutes. Then it was set on the shelf and I went on my merry way. Then I thought of this so I could use both the Pi and the Mindstorms Brick together. So that's what I did.

How Does It Work?
The Raspberry Pi collects this infomation in the command line:

Welcome, What direction should the motor rotate?
(Left or Right)
Great, How many degrees
(90. 180, 270, 360):

Then it flashes the led in a pattern. The Mindstorms brick can receive this signal using the color sensor. Then in this example it uses that signal to rotate a motor the specified degrees.

Lego Puzzle Box #2

I had a fantastic time designing this puzzle box, I was trying to make the most complex box of madness I can. This is what I came up with...


This puzzle is very complicated in the inside, but so I can show you how it works, the top and bottom can be detached easily.

This is how the top detaches

And the Bottom:
These are the parts that come off the top,
 Then you can see inside
(P.S. Some of the pneumatic tubes are not in there. Sorry)
The main things you can see from the top are the pneumatic pump (the blue thing) and the pneumatic switch

And the bottom:

One of the things on the bottom was the drive train for the pump, the long pole with the universal joints and the big tan gear transfer the power to the pump (in the top picture)

On the left there is a gear shiftier for the final door opening (much like the one on puzzle box #1).
