Marvin The Munny

I was given a project in school. We could design one of these blank Munnys and I ended up with my new desktop-companien, Marvin The Munny. We were asked only to paint it to give it a new character but no, I wanted to go deeper I knew I would take it apart.

Still first things first. A sketch of my work had to be drawn. I was inspired by the robot called Marvin out of the film "Hitchhiker's Guide To The Galaxy". After that, I cut open Munny`s head, to get a good look inside and to see how much space I had to play with. For the blinking eyes I cut out two triangular holes and insterted cut-to-size car-reflectors I happend to have found, the day before. My father occasionally assisted me with the wiring of the LEDs and the PIR detector in his belly.

For safety reasons I added a 200 mA fuse. It was a tight squeeze to get the wires into the body.

In the bottom of the wand you can see a magnet that triggers the On-Off reed switch, that`s located in his right leg.

Magnet position: up = Off                                               Magnet position: down = On

Here the "piece de la resistance". To charge him I use a Magnet based charging system.

As you can see, the Munny is in the wrong position, the magnets repel so he won`t short himself out.

In the correct position he gets attracted by the base the magnets snap together and he starts charging.

A quick look inside the Charging station:

So this is Marvin the Munny and as I`m typing his page on LMR he occasionally blinks at me and makes me feel happy.
