The resin has a low Tg (temp at which it turns goopy again) - somewhere around 500*F even for 'aerospace' stuff. Whereas recycling aluminum requires roughly double that temperature to begin to melt aluminum. The carbon fiber is t

The Mendelmax 3 & Fusematic from Makers Tool Works are built in the USA and sourced from US suppliers. The guy behind it has done more for the RepRap mechanical bits, aside from Joeseph Prusa. The Lulzbot mentioned below was based on t

While there isn't a specific section covering endnotes, they are interspersed sparingly as tonal changes in the narrator's voice. This effect is used in other readings of his works and is easy to follow.

While that was designed in 1984, the US DoD had successfully tested laser weapons over a decade earlier: 'The first was in 1973 when the USAF shot down a winged drone at their Sandia Optical Range, New Mexico, using a carbon dioxide GD

The 'Waveglider' [1] by Liquid Robotics employs a variation of this. Tethered to a buoy on the surface, the main underwater vehicle is propelled forward by the wave's upward force acting on spring loaded foils. [1] http:&#x

I suspect you'd still need 'supports' added when slicing - as often it's not so much gravity, but movement from the print head that causes things to go awry. As for layer/bed adhesion. Even here on Earth, the RepRa

Because it's fun. To be fair, 250W on an ebike is 'not fun' or anywhere close to the legal limits in the US (750-1000W). The happy spot seems to be 2500-5000W for most hub driven ebikes. I turned my bike down to 1000W this a

Fascinating, thanks. At what speed do you replay text->audio (ie realtime, 1.5x,2x,...)? Lastly, if you disregard price is the braille 'refreshable display' a better experience?

Thanks guys. I was familiar with Project Sanguine, but had hoped there were less ambitious public projects I had overlooked (perhaps closer to VLF which operates <30m seawater depths). After reading about the Navy E-6B aircraft, which t

So is this basically a TI Chipcon 2500 + Contiki + and a small ARM linux box acting as gateway? Are you just making Zigbee hardware API calls - or custom firmware? Are you a part of the Zigbee aliance? How did that effect development? As

Neat project. Will there be an API available? Or will I have to get creative with Form POSTs :).

Even though 'Nyan Cat' breaks things other plugins I'd like to use (like Powerline.el) - I still use it anyway. It's silly and I'm glad you made it.

@1m18s you see a syringe of fluid - so it's something similar. Maybe two laser-cut capacitive films with non-conductive fluid pumped through to make static 'buttons'. Probably a better MVP than what I suggested earlier :).

by stevenrace 13y ago
Simply put, glass is molecularly geometric - building actuated buttons into the glass itself isn't very probable. But a film of actuated buttons could be added much like with capacitive touch sensors today. Microfluidics is near the 1

'Galvanic corrosion' and applying a non-metalic layer between the cannon/deck would be my first thought. Now I'm curious as to some of the more 'colorful answers'.
