05:29 PM Jak_o_Shadows: Maybe I should make a phased array of ultrasonic sensors: https://www.youtube.com/watch?v=z4uxC7ISd-c
05:37 PM Jak_o_Shadows: For practice
05:37 PM Jak_o_Shadows: then I wonder if I could do it with the lidar sensors
05:43 PM Jak_o_Shadows: but harder - more inputs required
06:47 PM Jak_o_Shadows: Some guy had luck just driving it directly
06:50 PM Jak_o_Shadows: Hmm. Only 2.5 kHz bandwidth isn't great
06:51 PM Jak_o_Shadows: and if I want to do things properly, I think I need to keep phase in sync between pulses
06:57 PM Jak_o_Shadows: Which could work? Have a free-running thing, and switch it in with something
06:58 PM Jak_o_Shadows: Oh, I only lose like 20 dB by running at 5V rather than 30
