The prototype is finally ready for trash. Laid out like this, it looks to me like a ripped-out spinal cord of some cool trash can monster. Bizzare and disturbing. It belongs in the trash.

From top to bottom:

1. Solar panel connected to battery charger on sim808 breakout via USB.

2. 5 ultrasonic distance sensors connected to the Iteaduino via hand-braided cables. I braided those myself and it was the best hour of my life. Everyone should try braiding cables once in their lifetime.

3. GSM and GPS antennae connected to the sim808 breakout.

4. Li-ion battery connected to the sim808 breakout.

5. Sim808 breakout itself, connected via multiple data pins to the Iteaduino, and distributing power from the battery to the step-up transformer.

6. Cute little DC-DC boost converter which powers the Iteaduino.

7. Iteaduino itself, with a convenience sensor shield on top which provides lots of pins for all the connectors.

8. Temperature sensor connected to the Iteaduino.
