Art car 3

I've been working on benches for the rocket car. These are 2"x8" lumber bolted to 1"x1" ladder framed steel bars.

You can view more details in the imgur gallery linked below.

Also, here is a video of the mostly ready flame effect.

First pcb, woot

ghpi circuit board rendering
This is my first professionally made PCB. I designed it using in my spare time. OSH Park is producing the board and I will perform the assembly.

The board connects 1-wire temperature sensors to a Raspberry Pi for logging and display. There are also connections for an I2C/TWI display and an SPI RF24 wireless module. My plans is to release the source on github and sell kits. Please leave me a comment if you are interested in either one.

GHPi is what I am calling the project, which is currently in the prototype phase with my friends at Go buy some flowers from them.

Maiden fpv quadcopter flight

On 12/2/2014, I was finally able to fly my maiden fpv circuit through my backyard. This wasn't my first flight with the quadcopter or first time seeing the FPV video but it was the first time I flew the vehicle directly from the video feedback. The feeling is awesome and I can't wait to try this out on my airplane when conditions are right.

The quadcopter is a HobbyKing fpv250 and isn't strong enough to fly with a gopro. I haven't received my C-DVR yet, so I wasn't able to record the slightly frightening flights.

"The AMA FPV spotter must communicate with the FPV pilot to ensure the FPV aircraft remains within VLOS, warning the FPV pilot of approaching aircraft, and when avoidance techniques are necessary."

I need a spotter.

In total I lost three propellers. One was damaged due to a sudden and unexpected hard landing. The next was lost due to over tightening the new propeller onto the motor. I have seen these GemFan 5x3x3 propellers explode when spinning up so I don't risk running cracked or stressed GemFans. The last prop was lost due to a collision with a tree, which also pulled off a landing gear and the mounting hardware for the propeller. I could have also lost a landing leg but was able to find it.

I need to collect spare parts like propeller nuts and washers, landing gear and more propellers. This stuff should go in a case with the quadcopter.

Exploring Jacob's Well: Some footage for your enjoyment

Exploring Jacob's Well: Some footage for your enjoyment: Our ROV team (AustinROV) put together some video footage from our many build days and I must say it looks quite decent. We are by no means film school graduates or documentary film producers but we are learning.

Art car 2

Here is some progress on the rocket engine for my rocket car. The top part is the combustion chamber and the fire comes out the bottom.

The plan is to have an adjustable fuel/air mix to find the maximum flame effect. Oh, and attach this to a moving vehicle.

Enjoy this tiny video of the flame effect.
