  • Do you think one could use an arduino fona or particle electron board to send the gps data live via sms? Would 3G cellular work that high?

    To be more specific, by how much will timer1 need to be adjusted for lower frequency, by how much do the delays between OUTPUTS be increased, and by how much do the phases need to be changed. Is there any mathematical method to calculate how the code should be changed?

    Thank you for answering quickly. If you do not mind here is one more question... If (343.21 meters per second) / (40 khz) = 8.6 mm then the objects can be no bigger than 4.3 mm. If one were to use a tranducer that produced a lower frequency then how would that affect the project?Once again thank you for contributing.

    A few questions... - How effective would metal tranducers (like this http://www.ebay.com/itm/331415944083) be compared to plastic ones? - How would one scale this up so that it will levitate heavier objects?Thank you for making releasing this project!

    Hello. Could you also braze using silver and flux or could you soft solder using a silver bearing solder (one without lead and zinc)? Could one also weld only on the outside instead of the inside? Why or why not? Could a Cockroft Walton multiplier also be used for the power supply? Thank you in advance for any input.

  • NishB commented on hunter999's instructable K'nex Table

    Hello. This table seems to be pretty good for my needs. However how could I modify the design to only use 1,400 pieces or less but hold up to 50 kg?

    I also need the table to be at least 1 meter tall as well as the above. Now you might be wondering why. It is because I want to implement your design to build a tower for my county science/engineering competition where I have to build a "tower" with the above. You have a nice table. Thanks in advanced.
