Check out these two short videos that I produced for CUAUV over the summer (for the 15th Annual RoboSub Competition).
This first video is a short introduction to the vehicle, designed to create suspense. Producing this video helped organize footage, which was useful during the production of the competition video, shown below. This video also features some interesting cinematography that I was interested to try.
Secondly, this is our official competition video which was submitted to the panel of judges for the "team video" component of our static judging score.
I have resumed some work on my room's light / laser system in my free time (See last year's work here for details). I am currently writing the software and working out a few of the electrical bugs. My next step is beat detection and synchronization. I also want to redo my Android app. More pictures and videos will be uploaded soon.
Old features from last year:
Fluorescent White light
UV Black Light
Laser Spirograph Projector
Crude Laser Scanner (servo based) w/ Green & Violet lasers
Laser star projector with controllable rotation speed
This thanksgiving break, I decided to complete the project of adding lights to my bike in order to increase night visibility since I do a good deal of riding after dark. Also, pedestrians could not always see my bike as I approached. Building took about 8 hours. This is the final result:
My bike features 192 individual LEDs controllable over 6 PWM channels by an ATmega microcontroller. Eight light strips are attached to the bike via superglue and zip ties. All connections are watertight. The electronics are housed within a seat pouch which is water resistant as well. The pouch contains a 4Ah Lithium Ion rechargeable battery as well as an Arduino board attached to a custom built MOSFET shield which directly connects to the lights. It is easily detachable from the Arduino, meaning that I can simply unplug the microcontroller in order to update the bike's firmware.
I can select flash patterns via a single button mounted on the handlebars. The microcontroller interprets Morse Code from this button in order to determine which flash pattern to select.
As a bonus, the black wiring I used matches the bike's existing brake lines very well and as a result looks natural.
With the microcontroller, I can create various flash patterns. In the video below, I illustrate this. I can program additional flash patterns extremely easily and will in the future.
