    Acoustic Tractor Beam

    Today the transducers arrived! My son and I made this super-useless-thats-why-I-want-it project! Great!I used these transducers from the German distributor Reichelt:https://www.reichelt.de/Ultraschall-Sensoren/A-16P...They are not combo transmitters/receivers. You get a pair of transeiver and receiver. However the transceiver just works. I have to try if the receivers could be misused as transceivers, too.BTW. I would suggest to solder all wires in step 16 to the middle-pin of the switch instead of screwing them to the terminal of the inverter.
