Are math tests getting you down? Do you freeze up when you are asked to factor? Welcome to the De-Stress-Pen.  The stress pen is a biofeedback device that measures signs of stress such as clammy or cold hands.  Embedded within the device are humidity and temperature sensors (strategically placed for both left and…

Object: Pen for standardized testing

Twist: It tells you when you need to relax

Big lessons:

1. You can make your own sensors.  See http://www.gogoboard.org/node/12 (thanks Claire)

2. Heat guns can be used to adjust polymer vacuum casts but is best done as a two-man job (thanks Alicja)

The spoon is out.  A pen that tells you to chill out is in.  This morning I was given a ruler and stress testing card that is…

Last Friday the 13th inspired me to look at safety in everyday objects.  I spent yesterday analyzing objects that I normally take for granted and wondering how the sensors and output devices available to us can augment these things. 

Available materials:

sensors: temperature, magnetic fields, light and...?

output devices: sounds (just beeps), leds, motors and...?

Ideas I have so far:

1. Spoon for toddlers (or others who could use assistance)…

 I made a diorama of Oakland inside the case of the Ikea clock. It has a gritty and nondescript outside, but if you look through the clock face (my eyes) there is a lot of beauty, including a skyline, people of all shapes, colors and sizes, and space for circuit-board dogs to roam and play.  

I had…

Ikea confirms that the clock is made of white polypropylene, transparent polystyrene (laserable according to a google search, but settings tbd) and ABS hands. A quick check of the laser's effect on the polypro shows it is a good to go (5/40/5000). Since I am etching and cutting the actual 3-D clock, I can't do a practice on cardboard. I double-checked my geometries, used the calipers twice, pinned my pieces in place and flipped the laser on.

Next time: Zero the…

I decided to "get to know" my materials. It is $0.99, so it's okay to take a closer look.  The innards were the most beautiful part of the clock. The minimalist exterior masked circuit board green, yards of fine copper strands and silver solder. I took out every piece, documenting their placement with pictures. The speakers, switches and stands were all simple in shape, beautifully serving their function. It was gorgeous. And, it was broken.…
