My $1 yard sale find of the day. A Tensor model 5975 high-intensity mini task lamp, circa 1965.

To place the sensor out under a bush or fence for Halloween, I wanted to run a long length of CAT5 cable from it to the Arduino Uno running things. I mounted the rangefinder (a Maxbotix from Adafruit) to a RJ45 breakout board from Sparkfun, angling it up so the sensor can be placed low to the ground.
In the original application, I was able to hide this under a giant furry Neverbeast head (from Tinkerbell and the Legend of the Neverbeast) coming out of the floor in the lobby of Disneytoon Studios. But now I needed to place on outdoors, so I decided to model and 3D print this little enclosure.
Finally, I mounted another RJ45 breakout in my Arduino/WaveShield case and ran the voltage, signal, and ground wires to the Arduino.
Now, I’ll be able to set this up to scare trick or treaters this Halloween as they get near the house.
The above photos Star shot capture a few of my activities during the event: a talk on creative making featuring Chauncey the flower care robot, workshops I taught on lock picking, and an impromptu human body tricks performance during a talent show one evening.
Willpower, fortitude of spirit, and sneakers with a better grip helped me stick the jumping spider at Arnold Hernandez’s backyard 323 Ninja Training Grounds.
My first attempts at the Jumping Spider obstacle from American Ninja Warrior. I loved training on this, but definitely have my work to do on leg strength in order to start sticking it. Arnold Hernandez built this awesome course in his back yard, and is an excellent coach on how to approach these obstacles.
Slacklining! I’d never done it before, so I decided to dive in head first. Figuratively, and possibly literally.
What I’ve built is a “primitive” slackline which is made entirely from climbing webbing, two rappel rings, and four carabiners (ignore the extra carabiners and accessory cord in my photo above, those are for a different project). No ratchets or any specialized gear that I couldn’t repurpose for other climbing activities. The system is a really simple/clever friction lock that’s easy to set up, pull huge tension onto, and simple to break down with one tug of the line. This one can go for a 50′ run and cost $75 from REI.
