David Holliman: Electric Hourglass Update, 4/08
The most notable update for this week is that the scope of my project has been reduced due to physical limitations. After speaking with Tim May about the intended “electric hourglass” design, we determined that implementing plasma globes into the hourglass would prove too difficult. In order to make that design work, the hourglass environment would have to sustain noble gases in a vacuum. Next, I proposed that a visible electric current be generated through a high voltage arc between wires. Mr. May informed me that a large voltage and minimal space between wires would be necessary in order for this to work. He suggested researching spark gap generators; however, this mechanism requires a small gap whose aesthetic would be unimpressive given my initial vision.
Given these restrictions, my current design intent is to incorporate lights into the hourglass structure and have that light captured within a central part. I envision this part using reflective properties to capture the light and “glow” in a manner that still executes my design’s aspirations.
The next week, I will begin constructing the hourglass structure from wood material purchased at McGuckin’s. Also, the glass portion of the hourglass will be acquired. In parallel to these activities, I will begin to gather information and components needed for the lighting portion of my design.
With this altered scope, my project should converge without difficulty while still achieving the “electric hourglass” aesthetic!
