Once again The Onion’s hard-hitting satire draws blood…
Potential Vulnerability to Climate Change per Country
No wonder it’s so difficult to get us here in the US interested in climate change, and no wonder the wealthy here can be “deniers” - according to this map, we’re not facing the same backlash as everyone else.
Of course, none of this matters if we kill off the ocean.
Here’s the full six leg initialization cycle for my nascent hexapod.
Here’s more InstaMorph Robotics. I’ve got all the legs initializing, using the Propeller Project Board USB. I found that the servo connectors won’t stack very well, as they’re slightly wider at the top than at the bottom, making them wedge up after four or five of ‘em, so I just broke ‘em out in 3s, one position for each leg.
I had some fun times figuring out why it rebooted when I initialized the legs - turned out the 5v power supply I was using was browning out. Went up to a 2.5A unit and the problem is gone. We’ll see if this one’s got enough gas to power servos under load instead of just waving in the air. Video of leg initialization to follow.
Here we have a handful of leg units assembled from 9G servos, steel wire, InstaMorph, hot glue, and heat shrink tubing. They all operate properly. Now I have to make a body to attach them to and make a breakout for my Propeller Quickstart IO connector.
Also, there’s a closeup of the leg construction, showing how the InstaMorph connects the two servos in the “thigh” of the leg. Excuse the thumbprint. :D
This is a single leg from my 9g servo-based hexapod design performing a simple keyframed walk cycle. Sorry about the sound. Nothing on this stupid android device will edit video worth a crap.
Intel Galileo. So much promise, so little delivery. This is a great platform, but the slow IO makes it problematic for many embedded solutions. Embedded systems really want to be realtime, and much of the Arduino universe depends on sub 50us performance this IO system can’t deliver - or at least, does not appear to.
Back to the Raspberry Pi and the Gertduino, or Raspberry pi+Uno. Maybe PCDuino for more powerful applications?
Temperature and Aggression Research Goes Back to 50’s. Hard to believe it’s not a factor?
I’ve known there was a significant correlation between temperature and crime for some time. I find this map extremely interesting, even so.
