Analog Output Labs

The servo code was really interesting : the fake analog out strategy of pulse width modulation. I’m trying to understand it: As I understand, a full pulse cycle of two pulses, consists of a high pulse of 5V and a low of 0V, no V, of varying lengths (in order of a few milliseconds – […]

Norman – The Design of Everyday Things and Emotional Design

I really appreciate Norman’s passion for good design, and his anger toward bad design. I too sometimes have a hard time opening doors and working simple devices, and it makes me irrationally angry at that device, or person who made it, for making me feel so incompetent, but mostly for unnecessarily causing the stress and frustration. […]

Stupid Pet Trick

Allison and I made a squirrel nut cracker that cracks jokes as it cracks nuts. A few things I would like to remember: the funniness of things becomes more complicated when you spend hours working on the code of it (but maybe it would feel the same with the sadness of things, or the profoundness […]

Design meets Disability, Graham Pullin

Sorry to my many dedicated readers for my blogging hiatus. I need to catch up because I’m learning a lot that I am about to forget. This reading was really helpful. I have always been passionate about good design, or very angry about the lack of it, in every object. Pullin’s focus on the ipod […]

Electronics Lab

I soldered the ac/dc converter and used that for my power supply through a 5 volt voltage regulator. But I believe there is something wrong with it, it may be blown out or burned. At first it got very hot ( I may have wired it incorrectly the first time) then the voltage readings I […]

Fantasy Device

This device is something I desperately need or want really. It is a bag that follows you around like a child (its only like a child in this sense – that it follows you around, its otherwise inferior, obviously) or a trained mule. One would be able to put into it anything they wanted without […]

Lab 1 Blinking LEDs, Getting Creative

I wanted to move the switch to somewhere functional, so I converted the project into an occupied/available bathroom sign, modeled here by Donna. When the door was locked the light turned red. [wpvideo USu3ltnY] Switch Open: Switch Closed: I just saw that Ezer also made an amazing occupied sign! But with more applications: http://www.ezerlonginus.com/?cat=4

Sensor Walk

Going on a walk around my neighborhood with an awareness for sensors, I noticed more obvious sensors where there were less people. For example, on Bedford Avenue, where there were lots of people during my walk, I mostly noticed card swipe sensors, buttons, light sensitive street lights, and those loud door beep sensors in stores.
