SB-1 Science Package harnas

This Thing is deprecated and replaced by: http://www.thingiverse.com/thing:516797

This is a harnas for adding 'science packages' for the SB-1 to take to the murky depths :)

To make (and i am serious about all of the ingredients):

• Print the STL, this gives you the harnas in 2 halves.
• Wait for a holiday when the Kinder Surprise Mega eggs are in the stores and buy as many as you want to make Science Packages.
• Eat chocolate
• the harnass fits a 9V battery, a PCB with headers for an Arduino Nano, an Arduino Nano and some spare room for additional components, depending on your liking.
• Solder your Electronics on a PCB no larger then 5x4cm and solder the Nano's headers on it at the left side of the PCB with the USB port pointing up. (i'll post a Fritzing file of an example soon).
• insert, PCB with Nano and a 9V battery attached into the harnass (i'll only fit one way). Insert the harnas into the Kinder Surprise Mega container and put on the lid.
• You now have a science package that you can insert into the SB-1's sidetank with lid as made available in this Thing: http://www.thingiverse.com/thing:33097

Have fun running underwater experiments!

Little background: I wanted to test out the PX40 pressure sensor for measuring depth. I didn't want to make extra holes in my SB-1 for the tubing and such, and it didn't have room for the Arduino Nano and 9V battery anyway. So i made something that i could mount on the side of the SB-1. The regular Kinder Surprise containers proved to be very adequate watertight containers, but too small to fit an arduino, a battery and the PX40 (which is quite a bulky chip). Then, during easter (duh), i noticed these supersized Kinder Suprise eggs, and i though: 'supersized eggs might contain supersized containers!'. I bought me a couple, and apart from tasting deliciously, there were indeed larger sized containers in them with fluffy toys inside. Tossed the toy out, enjoyed the chocolate, and i tested the container for watertightness. And waddayaknow: they performed just as well as their smaller counterparts!
I edited the center section of my first SB-1 side tanks to fit the shape of the container so it wouldnt shift, added a lid for easy access to the container, and now the SB-1 can take cargo with it. In my case: a 9V battery, an Arduino Nano, a PX40 pressure sensor and a LED for status display. Later i added an APC220 443Mhz transceiver. And added a plastic tube to the Kinder container to house the antenna.
I'll post pictures of these, it'll make things much clearer ;)
