Here are two Ten Mile Square blog posts about our recent trip to Shenzhen, China. Trying to get a little closer to that vast electronics ecosystem.
 
It's all that and a bag of grey market chips.
We recently took a trip to Shenzhen, China. Shenzhen is a major city in Guangdong province, located just to the north of Hong Kong on the Chinese mainland. It's also the epicenter of the Chinese el...

Robo-hand plays RPS - This is a project my son Gordon's robotics team put together in the last 2 weeks for the McGill Robot Club. The player's hand is recognized with OpenCV and the robot hand reacts. Kind of cheating, actually - but a cooler project this way. The video shows an untrained hand. If the player is already in the OpenCV database the reaction is almost instantaneous. Gordon did the mechanical design and build.

Here's some video of the TinyG demo we showed at MakerFaire NYC 2014. Riley built this monster machine (over 1 meter long) to illustrate stopping pendulum motion in 3 dimensions using precisely timed and executed moves.

Believe me, it's not a living. But if you aw willing to soak up all your extra time it's a gas. No application for this demo, other than perhaps automating crane operation. The board itself is in desktop CNC, 3d printers, wire benders, pick and place machines, solar panel production lines, flame throwers and I'm sure lots of other applications we don't know about.

Found at a Chinese restaurant. Someone at Microsoft really should have looked into this.

Looks like early Sunday morning in Amsterdam. They look hung over and she's a little off key at first, but it's great. The second tune they do (about 4:14) is the one you may have heard - Golden Age. They also look like they are waking up. I love the tram bell in the background - sounds so Amsterdam.

It's worth noting that this is a diagnostic vid. The clunk at the end of the arc is abnormal. The other version of this doesn't do this is here:

My Three Squirrels

I ran across this the other day:

Shorter version - Squirrels outnumber people in the US by about 3 to 1. So these are my three squirrels

I'm not making this up. Crafting with Cat hair is a real book. Starting from the premise that you can make felt from any animal fur - why not clean up your messy cat-haired house and get something out if it?

Or complete the cycle by spinning the cat hair into yarn and then knitting a new cat. http://www.amazon.com/gp/aw/d/1579128939/

The Synthetos TinyG demo at MakerfaireNoVa 3/16 featured a pendulum demo with three robot spectators.

How do I get added to this special list? ;-)  I'm not a coder, so probably no help there, but god knows I have a couple of spare printers lying around! :-)

It's the simple things - part 2
Having gotten the individually switched power strip in place the next step was to find color coded USB cables to keep that whole mess manageable. These came from C2G (used to be Cables to Go) but I also found some for way less $ from http://www.valuetechsupply.com/2m-usb-20-ab-cables--5-colors--5pk-35679.html. I have not received these yet so who knows it they are good or not (will report back later on this)

Bragging rights
We got an Editor's Choice award at MakerFaire 2012! I'm part of Synthetos.com where we built TinyG and the grblshield. I also published an article in Make a few years back about how to build a lightbrick - uController controlled LEDs embedded in acrylic. I was also an early member of CyberCash.
