Musical Tesla concert is electrifying

musical_tesla_coil

Hackaday reader [Tyler Laseter] wrote in to tell us about an event that he and his fellow Tesla Orchestra team members are hosting next month.

The “Open Spark Project” is a concert event taking place on May 14th, which melds together electricity and music in spectacular fashion. The event features two large Tesla coils which are tuned to play musical notes while shooting bolts of electricity through the air.

Musical Tesla coils are nothing new around here, but we have yet to see someone allow the general public to play music on their coils. That’s what makes this event unique – anyone is encouraged to submit their to the Tesla Orchestra team, which will then be played back via a live video stream next month. Their web site offers up all of the technical details as well as the file format requirements for submitting music for the event, so get started on your entry today!

If a passive approach is more your style, stick around for a quick video demonstrating their coils’ abilities. Sure it’s Lady Gaga, but we won’t tell anyone you watched it. Plus, it’s totally legit when the song is being played using 20,000 volts.

The polyplasmic archophone

The polyplasmic archophone is a fresh approach to high voltage “arc music“. They are using  an Arduino clone to convert signals for the ignition coils. It is still unfinished, but the effect is decent. In the end it will have 2 tiers of voice coils for a total of 13. They are using different materials for the antenna so they can get different colors of sparks. You can see a video of it after the break and we must say the effect is quite nice. Change the lighting on that video and we could imagine this being the set to a [Joules Verne] movie.

Adjustable Tesla coil build

This coil has no trouble shooting sparks across four meters of empty air. [Finn Hammer] has been putting in some long hours on this labor of love, and we put in some time reading through his progress thread. He started down this path about a year ago and every step of the way he produces beautiful work. We enjoy seeing his prototyping techniques, moving from concept to hand drawing to CAD diagram before starting the physical build. Check out the demo video after the break and as you read through his thread look for the green arrows that lead to other videos and resources.

Wireless electricity

[Eric Giler] has a talk available over at TED that discusses and demos delivering electricity without wires. Called WiTricity, these methods were developed by a team at MIT a few years ago who were working off of the concepts of Nicolai Tesla. The facts shared about our current energy delivery system are a bit shocking; we’ve spent over $1 trillion in infrastructure and produce more than 40 billion disposable batteries each year.

The demonstration in the video starts about 6:30 into it. At first we see a flat panel television powered wirelessly from about 6 feet away, then the T-Mobile G1 powered from the same distance. The thought of new TVs coming with WiFi and WiTricity standard would mean just hanging it on the wall with no cords to run. We can also image cellphones that have a battery only for backup purposes when you were not near a transmitter.

The power transfer occurs between two coils that resonate at the same frequency and only that frequency. This remind us a bit of Orson Scott Card’s fantasy communications device from the Ender’s Saga.

Solid state tesla coil

While researching solid state Tesla coils we stumbled across this old project. As you have probably guessed from the pictures, this coil is meant to actually play music. Knowing how to add eye catching flare, the coiler uses a Plexiglas frame turned light pipe; only to be complimented by an audio amplifier complete with graphic equalizer. There is a video of the coil in action on YouTube. We have covered singing tesla coils in the past. Other twists on the classics include the tesla coil guitar amp and a hand held plasm gun.

Jacob’s Ladder

[jandgse812] shows us how to build a Jacob’s Ladder from mostly household parts.   The bulk of the instructions for this project are included in the downloadable document, there is a downloadable video as well. Be sure to follow to the end where he shows us a much safer and possibly better looking revision. The Jacob’s Ladder has become standard fair for any mad scientists laboratory. If you plan on having a workshop suited for world domination, it absolutely must have one of these in it. Be careful though, the high voltage can be deadly.

900,000 volts at your fingertips

van_de_graaff

[Nickademuss] has put together these great instructions on how to build a 900,000 volt Van De Graaff generator. For those unfamiliar, Van De Graaff generators produce massive amounts of static electricity. They are usually the things you see in science centers that make people’s hair stand on end. [Nickademuss] put a lot of effort into this, he created 3D models and diagrams for many of the steps and gave a very detailed step by step breakdown.
