Looks like ABC will be airing some robot battles soon.
BattleBots returns to television this summer, to the delight of all.

To try and pull some weight on the CNCR I've designed a dust shoe using Fusion 360. The top printed flawlessly and fit perfectly on the router and dust hose.

Bottom brush shoe is a bit larger than the build platform on the rusty old Rep1 so I have one printing just for test fit. Have a larger platform planned for such occasions.

Yes and it is a polycarbonate part for some visibility.

"...Today, you can send a design to a fab lab and you need ten different machines to turn the data into something. Twenty years from now, all of that will be in one machine that fits in your pocket. This is the sense in which it doesn't matter. You can do it today. How it works today isn't how it's going to work in the future but you don't need to wait twenty years for it. Anybody can make almost anything almost anywhere.              

...Finally, when I could own all these machines I got that the Renaissance was when the liberal arts emerged—liberal for liberation, humanism, the trivium and the quadrivium—and those were a path to liberation, they were the means of expression.

That's the moment when art diverged from artisans. And there were the illiberal arts that were for commercial gain. ... We've been living with this notion that making stuff is an illiberal art for commercial gain and it's not part of means of expression.

But, in fact, today, 3D printing, micromachining, and microcontroller programming are as expressive as painting paintings or writing sonnets but they're not means of expression from the Renaissance. We can finally fix that boundary between art and artisans."

My name is Radio...Radio Shack.
The challenge RadioShack faced was the slow erosion of the very leisure time the company profited from by filling. RadioShack filed for bankruptcy protection last week.

Good Sunday reading.
Built and designed in the 1960s after the A-12 Oxcart, the SR-71 Blackbird is still the fastest, most vanguardist air-breathing airplane in the history of aviation. These once classified photos reveal how Lockheed built both birds in secret, in California. They look taken at the Rebel base in Hoth.

I need two non-polar 10.0uf 100v capacitors if anyone has a couple they can spare. Not worth the price of shipping and not sure when I'm in ATL next to hit Fry's. I'll pay you cash or frosty beverage for said bits, of course!

I just think it's nice to have internal wiring "out of the box" so to speak. Not very transformative, but cool in prototyping phases for sure.

Giant milestone this week with our CNC router. +Jason Brown has been relentlessly pursuing getting our beast of a CNCR (5'x10' bed) dialed.

Trying to get as much mechanical backlash (http://en.wikipedia.org/wiki/Backlash_%28engineering%29) out of the machine itself is a challenge that has taken many months. Once you have done the best you can on the physical machine's consistency, there are options in the CNC software to compensate.

This is the path that came to an abrupt success Thursday. We had worked on re-tensioning the X and Y axis belts from what we think was some break in loosening. Cutting a standard pattern for troubleshooting for the 3rd time, we were scratching our heads as to what to try next.

The software backlash compensation was the key. Jason entered what he thought the backlash was we were experiencing from the test cuts into LinuxCNC. As we cut the fourth time, we were jaw slack at the results. About as close to a perfect pattern as we could ask for! Did a little dance.

We've upgraded numerous parts over a year at least, with some with help from the community (THANK YOU) and including a long interruption for the bot arena build. We are looking forward to some fun projects now that this is dialed for accuracy.

Some flat pack furniture being high on the list. (see: www.opendesk.cc)

Congrats and thanks to Jason for his diligence and patience.

The Replicator is back on line. Two new nozzles did the trick. Kit is printing away as I type this scrambling to prepare for Robot Battles #53 at Chattacon 40.

Good to see this.
For years, the U.S. has ceded more and more of its manufacturing to low-cost corners of the global economy. Some firms now want to come home.

If you see a missing blue knob around the shop please let me know. Looks like our insulation remover may have used the white chair and stepped on the lever on the way down. (Lever was found in the full open position, I leave them at 45degrees) see pics below for reference.

Thanks!!!

It may have rolled under something.. just get a carbon fiber gearshift nob from O'Rielly of you don't locate it.
