range finder

Short post on Successful data out of OSLRF-01 Laser Range Finder

It's late and I'm going to bed. My eyes are blurry, and I've got a headache... but!!!

I'm getting reliable (for the most part) Distance readings out of the OSLRF-01 as evidenced here in my putty dump.  The "ACTUAL" distance to target was in fact 2.67m.  I've got a fairly consistent reflection or ghost at 0.67 and few more stragglers that I will work to filter, but I'm quite pleased.

Looking for ideas on a I2C Pan/tilt stand-alone sonar

This quest to build a stand-alone I2C pan/tilt range finder controller started with an article here by Ladvien.  In    https://www.robotshop.com/letsmakerobots/node/39130, Ladvien explores using an ATtiny85 (84) as an I2C motor controller...

And in https://www.robotshop.com/letsmakerobots/node/39222,   Chris the Carpenter   gives us an awesome pan and tilt code example... so...

Has anyone heard of this Ultrasonic Sensor?

The model is SP-40-38F. You can find it here: http://www.cutedigi.com/product_info.php?cPath=278_295&products_id=4282&osCsid=d133de8082a4556d02f27cdf248ae912

I would like to buy a few but after looking at the site, I am a little hesitant to send them any money.


360 Range Finder

I just received my SRF05 and I can't wait to start using it.  While I was thinking about it, it occurred to me that I always see the SRF05 mounted on a servo, which allows maybe a 180 degree field of view for a robot. I wondered if anyone ever mounted a range finding sensor on a motor so a robot could see in every direction. 

I think I may try to build a 360 degree range finder, but I wanted to open this as a topic and get some ideas. Here's what I'm planning. Let me know what you think.
