I'm in Expo Hall zone 2 near the doors facing Delaware St. for #MakerFaire 2015. See you here! I'm showing my fluid turbulence discs.

+John Bump Its the house hold ammonia you can smell, Anhydrous you wouldn't smell but for several seconds then you can't smell it any longer your nostrils will be burnt and your lungs will have no oxygen.

two sources of anhydrous ammonia are as fertilizer at the farm co-op, or refrigerant for big commercial freezers. unfortunately going around asking for small amounts will get the cops called on you for making meth.

The climate change "debate" has become so protracted and poisoned that I believe continued effort spent on it is counterproductive at this point. Even if scientists "win" and convince everyone that the climate is changing, the next debate will be centered around how bad the changes really are, and the debate after that will be centered around whether it's too late to remedy.  Instead of decades of continued back-and-forth with the climate deniers, we can promote more direct and actionable messages such as "being dependent on foreign oil makes our country vulnerable", "wasting resources is unpatriotic",  "building nuclear, solar, and wind power plants will make energy cheaper in the future", etc.

Sorry about gross exaggeration. I stand corrected. I didn't realize wind electricity generation was up to 4.04%. Www.eia.gov

Boiling ammonium hydroxide and condensing the dried vapor at -50*C to make anhydrous ammonia. DIY?

Learn how to build your own fluid turbulence disc like the ones that I brought to Maker Faire.  It's an easy weekend build!
When I last visited the Carnegie Science Center in Pittsburgh, I saw a really beautiful interactive fluid exhibit demonstrating the swirly, churning patterns of turbulence. The fluid was contained in a 3-foot-diameter disc, about 2 inches deep with a sturdy glass top. A large Lazy Susan bearing supported the disc …

It works just fine when wall-mounted.

Greasy old cantankerous machine- need more performance: rebuilding not a car engine, but a SEM.

The column in this JEOL JSM-T200 is super simple.  In fact, there is no alignment except for the gun itself.  The apertures are molybdenum foil, and I was able to clean them by heating to almost white-hot temperatures in vacuum, then cooling and returning them to the scope.

Not laser-cut!
 
Cut Paper Bacterium

Artist Rogan Brown (previously) recently completed work on this new cut paper sculpture titled Cut Microbe. Four months in the making, the piece is a continuation of Brown’s exploration of the human biome and was inspired by the form of salmonella and ecoli bacteria (this 44″ sculpture is about half a million times bigger than the real thing).

Introduction
I previously worked on Virtual Reality and other hardware at Valve.  I currently work at Google[x].

Prior to starting at Valve, I built computer peripherals such as keyboards, mice, and joysticks that were designed to be used inside MRI machines.  My company, Mag Design and Engineering, sold these devices directly to researchers at academic institutions who used them to publish scientific papers in peer-reviewed journals.

After work, I spend time on many different types of projects that usually involve circuit design, machining, material selection, and general fabrication/hacking.  My favorite place to be is my home workshop.
