Building an 8'-long robotic arm with a chainsaw on the end is no small feat. Here's how it was done.

We have a OSH track at this years Tulsa School of Dev conference.
Registration is free if you're interested in attending. We'll have talks on Neopixels, the Sparkcore, basic mechanics and motion transfer andt he internet of things.

I'm curious if some of you may have experience in this matter of interoperability.
I'm going to try integrating the APA102 ( dotstar ) LEDs into a project that has an existing device on the SPI bus. I was attempting to use neopixels, however as the device on the SPI bus ( an NRF24L01 wireless module ) uses interrupts in it's codebase neopixels don't work. 

Will I be able to use the dotstars and communicate with the wireless module at the same time?

FastLED automatically turns interrupts off on AVR chips when needed, and back on afterwards. The problem is that the Neopixels are so slow that interrupts are turned off for so long that it really trends to screw with pretty much any kind of interrupt-based communication at all.

We sort of all take it as axiomatic at this point that you can't have these three things all at once: an AVR microcontroller, WS2811/WS2812 Neopixel leds, and normally-functioning interrupt handlers.

Moving to APA102 is one popular solution. Another is having a separate microcontroller handle the interrupt code, and have it communicate with the LED MCU via a non-interrupt-based (serial?) connection.

Wrote a little bit about my experience so far printing custom made drones. 
Recently I became interested in building my own multirotor UAV, often called Drones and other stigmatized names. Specifically I wanted to build my own quadcopter from the ground up, the type with 4...

Please become a member of CAD Drones! Your work would be so useful to our members who are new to 3D Printing and Drones!

Nice to see someone so passionate about visualizing systems.  I couldn't agree more.

Incase you didn't get blasted with the invitation… I probably have to add you to one of my circles, if you have issues joining.

For those that aren't aware I've been very interested recently in starting a discussion around creating our very own community owned hackerspace. If you would like to be a part of the planning or have ideas/desires to share, please join this google group!
https://groups.google.com/forum/#!forum/tulsa-hackerspace
Also share it with any parties you think may be interested.

Definitely need a lab with some largeform monitors for us GIS nerds.
