The beam could definitely be tuned based on the wavelength and location of each transducer, but for this project I wanted to keep it simple and accessible to just about anyone. The transducers are just put neatly into the perfboard and soldered with the correct polarity to make them in phase with each other.

Just about any logic level N Channel mosfet will work, the current is only about 1amp.A lower input gate capacitance will be better though

Imagine the acronym PEIR placed vertically. P is the top and R is the bottom, to go up (towards P) you would have to multiply. Ex. R*I=E, I*E=P. And to go down (Towards R) you have to divide. Ex P/E=I, E/I=R. The formulas in the outer circle are also pretty cool, but unrelated (kina) to the PEIR method I was talking about. All the formulas in the P quarter can be calculated to find Power, E quarter can find Voltage and so on!All it really takes is practice, practice and more practice!

Thanks!

Youre a legend! Thanks!

So cool! Thanks!

Wow! Thanks for your vote, it means a lot!

Thanks!

Funny you should say that because I'm working on one of my next projects (brushless micro) right now!

Thanks! Go for it dude! I might have to warn you though, it's an addicting hobby!

WOW! This is amazing! The rest of us dont stand a chance in the 3d printing contest! How in the world did you make the parts list look like that?!

When I first started this project, I was just as confused as you are about this! Because how confusing I know it can be, Ill try to give you as much info as possible. For a "regular" led strip, you can only achieve single colors such as rgbw. Using this strips will only result in a solid red strip, a solid green strip and so on, though you could flash between colors. To be able to perform animations, you will need to buy individually addressable led strips. These will have a Positive tab, a Negative Tab and a Data tab. The data tab can be connected to an arduino or other board to address each individual LED, meaning you can change the color of each led to perform animations, in this case a cycle through the rainbow. The best place to find these would be adafruits Neopixel, but...

The best place to find these would be adafruits Neopixel, but since they can get quite expensive, I bough a WS2821b LED strip. In summary there is a difference between LED strips, if you want to perform animations, you will have to buy a strip where each LED can be separately controlled (normally called individually addressable LED strip)

Thats weird... They were working an hour ago. Thanks for letting me know, ill fix it!

Yes I would definitely recommend the shorter arms! Total cost, not counting tools, id say around $80-$90

Im working on it right now!

Coming soon!

Sure! I was planning on posting an instructable,i'm still kind of shocked someone else had the same idea for the cnc contest! Great minds think alike!
