(...) I beleive "hard" rigid materials have high reflectivity of sound, such as metal and granite, etc. Pourous materials absorb sound, like brick and wood. You may have notised that sound absorbtions usually involve foam pads on the walls and (...) (28 years ago, 14-May-96, to lugnet.robotics.handyboard)

(...) I believe it would matter what type of material you reflect the pulse off of, I would guess. Different surfaces have differenc acoustical properties. Just like they have those silent rooms and echo chambers, etc. (28 years ago, 14-May-96, to lugnet.robotics.handyboard)

| | 15' max measurement
|
|
Yup, it looks like 15' is about as far as I can measure. In fact, if the distance is _too_ great, I start getting weird measurements, on the order of 8 or 9 feet. Strange. I turned the gain up a bit, which keeps those erratic measurements from (...) (28 years ago, 14-May-96, to lugnet.robotics.handyboard)

Well, I finally got my Polaroid sonar module in the mail, and I got it working with my Handy Board tonight. My feelings thus far: This thing is pretty neat. However (of course), there are a few quirks that I'm trying to figure out. Distance (...) (28 years ago, 14-May-96, to lugnet.robotics.handyboard)

Hi, Under Interactive C, something is resetting bits 6 and 4 of the SPCR register (0x1028). Whenever we try poke(0x1028,0x5C); and then do a peek(0x1028), we always get back 0x0C!!! Trying to figure out whether this was an instantaneous thing or (...) (28 years ago, 12-May-96, to lugnet.robotics.handyboard)
