The HackSignal - HackPGH's "bat signal" equivalent out of common household parts
Goal: To build an extremely high powered mostly coherent light source to display cutout images on clouds.
Master ToDo
- Source Carbon Rods
- Carbon Gouging Rods for Arc Gouging (1/4")
- Decide on/Source Materials for Parabola
- Aluminum Flashing - but how to join it together?
- Pop Rivets?
- Chrome Tape?
- Aluminum Flashing - but how to join it together?
- --Get a Garbage Can-- Done.
- Build power system
- High Amperage, lowish (50-60V) voltage
- Build arc PD controller
- Coils and a spring - see the light source section below.
- Source the mounting system, or make a mechanical design.
- Build parabola
- Plans below - need to decide between the two styles.
- --Mount system-- Done.
- Test and refine (Kickstart for more funds?)
- Build cutouts (HackPGH logo, others?)
- Play with device
Hardware
Light Source: Carbon Arc!
- We are totally making one of these PD controllers for arc lamps: http://chestofbooks.com/crafts/popular-mechanics/Amateur-Work-4/Principles-Of-Arc-Lamp-Construction.html
- Small Change - horizontally mounted carbons with a spring to simulate gravity (providing an I - making it a PID).
- Other Arc Lamp Hacks: http://members.misty.com/don/carbarc.html
- Rod Data: http://www.boyocarbon.com/pro-air%20arc%20gouging%20carbon%20rod-e.htm
Power System: Unknown!
- We need the equivalent system of an arc welder.
- High Amperage, not High Voltage?
- Higher Amps - Larger Rods!
Reflector: Parabola!
- How to Make Big Paraboloids out of flat segments: http://freespace.virgin.net/ljmayes.mal/var/parabola.htm
- Another method of the above: http://ashokk_3.tripod.com/srinivasan.htm

Links: Light Design!
