Crashes and Accidents  - 
 
First flight & crash of a Tricopter today.  I think the servo came loose and sent it into a death spiral.  The impact with the ground sent the camera flying.  I was recording at 60 fps and was able to get a couple good screen shots from the video as it flipped though the air.

Great shots! Sorry about the crash though. Lol!

I recently built a beer fermentation chamber using a Peltier (TEC) plate for cooling.  I built the chamber out of 1-1/2" Styrofoam insulation and a lot of duct tape.  I salvaged a couple old Intel heat sinks and fans for either side of the TEC.  They are mounted to a cheap cutting board that I cut a square hole in.  It's all controlled with BrewPi [1], which is a RaspberryPi + Arduino project that is typically used for controlling chambers made from modified refrigerators.  I made a quick a dirty Arduino shield to easily connect the DC relay and temperature probes.

I wouldn't call it a huge success because it's only barely able to maintain a delta of 10F (5.56C) when cooling.  Thankfully that's enough for the batch I currently have fermenting in it.

Some things I learned:
1) Building an efficient thermal chamber is hard.  Buying an old/used fridge sounds way easier.
2) The 92W Peltier (TEC-12706) I bought is not powerful enough.
3) Cutting sheets of Styrofoam in a uniform manner is a pain.  I probably should have used nichrome wire and some kind of jig.

The end result of this project is that I came up with an even better idea for a more efficient way of cooling a fermenter.  Stay tuned for that build.

I was thinking of using some 3/8" ID SS tube for a fluid transfer cooler. Basicall run it straight down, then wrap it around it self on the way back up. On the top, you can just fit the two ends snug through some holes in a carboy stopper. Then plumb water in/out lines to it through a pump that's sitting in a 1+ gal pitcher in a nearby fridge. The cold water flowing through should pull a ton more heat than a peltier plate.
I was going to wire the water reservoir and controller into my existing kegerator so i could hot-ferment my belgians outside while still having good control. Just havent used belgian yeast in a while :) 

If it works well and your fancy, you could daisy-chain a few in series with electronically controlled servo valves to adjust the flow bias for different recipes/target temps.

Wow, Freeside has really changed since I was there!  It looks amazing.
 
I was recently in Georgia for a for a non-HaD reason. This was my first trip to Georgia and it was hot, really hot, something I’m not too accustomed too. They also have nice condition roads there, something else I’m not accustomed too. I did have some…

I recently built another custom carbon fiber nano-quadcopter.  This one uses larger and more powerful 8mm motors and a custom two-layer carbon fiber frame joined with nylon screws.  The result is a ridiculously rigid frame and very sturdy motor mounts.  I made a video this afternoon of it's first flight:  http://youtu.be/GvVXugqQPhI

I designed the frame in OpenSCAD and cut it on a Roland mill that I have access to.

Next step is to add FPV components.

Details:
* Motors: CL-0820-15  http://goo.gl/gFNNoE
* Flight controller + RX: Micro MWC  http://goo.gl/wdT7hY
* Frame is cut out of 1mm thick CF sheets.
* Firmware: Multiwii 2.3
* Batteries: nano-tech 950mah

Edit:
OpenSCAD files now on github: https://github.com/raiford/carbon-nano-quad

+Joseph Slaker Yeah planning for 5.8GHz.   Still waiting on a couple ebay shipments.

If anyone is interested I just put the OpenSCAD files on github.  The are still a bit messy so expect some clean-up over the next couple weeks.  https://github.com/raiford/carbon-nano-quad

"When discussing self-driving cars, people tend to ask a lot of superficial questions: how much will these cars cost? Is this supposed to replace my car at home? Is this supposed to replace taxis or Uber? What if I need to use a drive-thru? 

They ignore the smarter questions. They ignore the fact that 45% of disabled people in the US still work. (Source: page 20) They ignore the fact that 95% of a car's lifetime is spent parked.(Source) They ignore how this technology could transform the lives of the elderly, or eradicate the need for parking lots or garages or gas stations. They dismiss the entire concept because they don't think a computer could ever be as good at merging on the freeway as they are. 

They ignore the great, big, beautiful picture staring them right in the face: that this technology could make our lives so much better."

I built a ferm chamber a while back with a peltier unit as well. I have no real issue maintaining ~15 deg. below ambient. If it is warm in the house and the fermentation is at peak, I add ice to lower the temp. The peltier seemed like it would be great, and in some ways it is. There is no coolant, no lines, and no hassle. At the same time it is really slow to get to temp, and it runs constantly to maintain temperature. I keep saying that I am going to buy another unit and cut another hole in the box. I used a computer power supply and left another set of wires connected to the supply for expansion. Bigger fans on the unit may help as well.
