Passage of time v2.5 with Switches
I added switches to the fourth iteration of the passage of time. 1 rocker switch for on/off, 1 toggle switch which switches between 2 patterns, 1 momentary pushbutton switch that changes the pattern when the toggle switch is up. The switches are mounted on a separate short box with holes drilled using the dremel tool and attached to the bottom of the taller box. All the switches are hooked up to the Arduino using a breadboard.

The passage of time v0.2
The third iteration of the LED passage of time. This is a much higher fidelity construction than the last version and a lot of time was spent on the outer body construction. The inside of the container is sandpapered and an additional sand papered plastic layer is added on the inside to diffuse the light. Strips of black paper are stuck on to the outside of the container to block out light in specific areas and create a slat like effect. The top and bottom of the container are painted black to avoid leaking any light. The code is also modified for a different pattern.

The passage of time v0.1
My second iteration of the LED time piece. This prototype is a much higher fidelity and uses a tallish container I got from the container store. I’m using the container upside down with a hole cut at the bottom end for the USB cable and the Arduino stuck on the lid of the container. The LED’s are mounted around a tall cardboard structure, in 3 rows, which sits tight once stuck inside the container. The LED’s light up one row at a time and the light appears to move up and down the container. Row 1 and 3 are blue LED’s while row 2 is green LED’s. Kitchen towels doubled and nicely tucked into the container are used to diffuse the light.

Simple sequencer
This is a simple sequencer programmed in OpenFrameworks for an avsys assignement. It uses 8 sin oscillators which can be switched on/off and their frequencies can be cranked up or down to produce a looping melody. The speed of the looping can also be cranked up or down. Here’s the source code.

transistor toggle, astable multivibrator and a voltage divider
Three new circuits for physical computing. There are 3 circuits on this breadboard, from top to bottom – transistor toggle – the LED’s toggle when the switch is pressed, astable multivibrator – the LED’s fade in and out one at a time, voltage divider – the LED turns on in the dark. Additionally, I did my first soldering job, we had to solder header pins on to the power adaptor so it can power the breadboard.
