New Goal: If we can raise $14,000 or more, we'll be able to produce laser-cut enclosures for all donation levels $40 and higher! These will keep you safer from the plasma, and make the plasma speaker look really cool!
Update: We have reached the goal! Thanks for your help and support! We will be ordering a laser cutter as soon as the Kickstarter finishes, and we'll document the process via the update system. Stay tuned!
The Making of the First Prototype
Many of us own speakers. They're pretty useful devices, allowing you to hear sounds and music from computers, mp3 players, and other cool devices.
Most speakers use electromagnets to vibrate air so that you can hear it. We built a prototype plasma speaker, which uses an electric arc to vibrate the air. It both looks cool and sounds awesome!
We want to share our creation with the world, and put together an Instructables about our project.
Also, we want to make it easy for people to assemble a plasma speaker. By offering a kit with a custom-made PCB and a set of tested components, we will make everyone's life easier.
The $40 kit has almost everything you need except for two components. Here's what you need to know about them.
Flyback Transformer (Included in $60+ kits)
You'll need a flyback transformer to generate the high voltage in the plasma speaker. You can find one in an old CRT monitor or TV, and then identify the primary and secondary coil.
12V Power Supply (Included in $80 kits)
You'll need a 12V power brick to power the plasma speaker. From initial testing, we think that a 4 amp rating should be good, but we'll do some testing to find out the optimum. You can find a 12V power supply from old laptops.
You'll need a soldering iron and solder to assemble the kit. These go for a variety of prices, but you usually can find a decent one at Radio Shack or Fry's for about $20.
What your money will be used for
We'll use your money to refine our prototype, and put together kits for you to assemble. Take a look to the right for the packages!
Add $7 shipping for Canada/Mexico, or $10 for all other countries.
A Big Warning (AKA, DANGER!)
Plasma speakers are dangerous. Use them for short periods of time in well-ventilated areas. Also, make sure that no bodily parts go near the electric arc. Proceed with caution. If you aren't comfortable assembling the plasma speaker, find some help. We're not responsible for you, you're responsible for yourself.
Who We Are
We're StudentRND, a student-run nonprofit organization that inspires students to learn more about science and technology. During the summer, we run a workspace where students gather and work on cool science and technology projects. We also partner with local high school robotics teams to offer them a space to work over the summer. Follow our summer adventures at Facebook.com/StudentRND and @StudentRND on Twitter!
