Long Range Narrow Beam Ultrasonic

cr0sh:
Something I'm curious about: Will we ever see any of your code, schematics, or physical setup, sirch?

Same here, I will be waiting few days for it since now is weekend, otherwise I will post very simple long range narrower beam laser implementation ( only use 2 ops + 1 dds + 1 ASIC ) and hijack your thread. :stuck_out_tongue:

just kidding.
