Did anyone happen to find a box/bag with two Raspberry Pis and some memory cards in the lab? I'm losing my mind ...

I believe it would have been in a brown walmart bag. The PIs themselves were just in the generic clear plastic containers. It's entirely possible they're in my shop somewhere. This is what happen when I clean ...

Hi everyone,

My company FDI is just an hour or so down the road from you in Huntsville, and we're opening a Design Challenge to everyone.  We're requesting proposals for a project that connects a Pi to our touch screen LCD interface called ELI (Easy LCD Interface).

The top five proposals will receive one free ELI valued at $119.00.  The top project utilizing ELI will also receive a $500 grand prize.

You can read more and register for the contest at the link below.  We can't wait to hear from you!

Small update:  Last night I got the DRO setup on the Z-Axis on the mini-mill.  Two more to go.  Anyone have an android tablet lying around? I'd like to integrate those into a larger screen with this: http://www.yuriystoys.com/p/android-dro.html

Today I ordered some cable / drag chain for the big CNC router.

Hey, it's Michael from the 4th Floor. Although I've only been using them for a few months, I'm beginning to appreciate the love-hate relationship with Replicators. How has Chatt*lab handled the amount of upkeep that the Replicators require? Do many people tweak them here and there, or is there a person who has really focused on keeping the MakerBots consistent?

+Michael Grilo It did! I've put it through it's paces over the last couple of weeks, and am slowly putting together my review of it. I'd be happy to bring it over one day if you wanna check it out. I'm at Computers in Libraries next week until Wed, but maybe Thurs/Friday? LMK...

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

We have acquired a sweet lathe. 12" swing variable speed, all the bells and whistles for our needs. Pleased to add this to our steadily growing collection of machines. It is a Logan 2527 and is in extremely good condition.

Hi @Tim Youngblood, I was mentioned by a friend of mine named Dan Baker, whom is a member of the Astromech builders group. I also happen to be a member of the Astromech builders group also.

I do have a question as it refers to 3d Printing: I have built a Mini Kossel printer and am not sure of how to calibrate it or to make sure everything is working properly. I happen to live in Flintstone, GA so driving down to the Chatt*lab Makerspace is no problem, please let me know if you could take a look at it and maybe help me with getting it to work.

Hi Tim, are you going to be there tonight, I got the firmware for a mini Kossel uploaded to the printer and have marlin installed on it also. But I'm finding it rather hard trying to get it programmed into the firmware of the dimensions and details on my printer into Marlin. I'm still puzzled about the err max temp on the printer on it too. Please let me know if you could help me out.

Please activate your personal networks: We are officially looking for a larger space in the 5,000 to 10,000 sqft range. Industrial raw is perfect. Need ground floor access and decent electrical service. Needs to be within the city limits and central to downtown.

Hey guys, smoking in the brewery (or anywhere else in the lab) is not cool.

However! The door in the brewery was pushed opened, from the non-lab side. So it's probable that it wasn't one of us. I'll let our fearless leaders handle that.

Thanks guys

This Zip Tie Lounge Chair from Opendesk.cc was the first furniture we cut with the CNCR. It took about 5 hours from start to finish including learning the toolchain for creating the paths and executing them on the machine.

The most complex and large project since the large '4' sign for the Chattanooga Public Library's 4th Floor. This was much more accurate to say the least after all the upgrades we have put into this incredible machine.

Huge thanks to +Jason Brown for his help in getting me up to speed on the tooling both virtual and real.f

Yeah, looks comfy. And, for exotic materials... that got me thinking. You could always go for an aspen slatted, unicornhide edged design, and frame it all up with unobtanium. Just sayin'.

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."
