- Power Supply Development
Jul 12, 2013 @ 10:36pm
- To power the raspberry pi, and sensitive sensors, I need a regulated power supply, but the larger devices like pump, servos, and valves all need a lot of power. The LiPo battery, while rated at 14.8V, can go above it. Wikipedia states that they get up to 4.23V/cell, so my 4 cell battery is 16.92V max. I was uncomfortable with most of the non-RC stuff seeing almost 17V when they were only rated at 12V (40% over spec), so I made a DCDC 17-10V->~12V Power supply, and a very large 5V power supply to power the servos (my searching gave me almost 2A as a spec value for them, and I want 3).

- RC Submarine project overview
Jul 12, 2013 @ 2:42pm
- I decided to build a remote controlled submarine out of PVC pipe, RC car parts, and a raspberry pi. Initial goals were to act mostly like an RC boat on the surface, and be able to dive autonomously and return video. Total cost as of today is about $1k, though I plan on updating that and keeping an accurate count of things.

This is what was used to generate the PCB, and it has problems.
