Crt wireless ultrasonic monitoring

Some may have seen my other "something else" with CRT tubes used as display devices, and this is a bit more detailed as to its purpose. Also some time back I posted some "Robo-view" video of my robot platform cruising around and the videos showed the robots eye perspective, as well as the human view, making use of those cheap 19$ wireless camera systems. The issue that I was having while watching the video was depth perception. Looking at a monitor, I could never really tell how close I was to something before running in to it(telepresence situation). What I wanted to do was add another dimension by making use of ultrasonic and/or IR systems and wirelessly send that data to me at my base station. Thus, the oddessy you see here is a start of that system development. The CRT gear is brutal, homemade circuits to drive the crt with proper voltage and add postioning controls so it can be calibrated to accept binary data. The binary data is sent over the el-cheapo radio control car electronics(I also posted about this way back when) from the scanner unit to the base unit using two channels. One channel carries the data itself, the second carries a sycronizing signal to let the CRT know where the scan head is pointing. The radio control cars I gut these electronics from are availble for under ten dollars, and I use them for everything under the sun including this. The ultrasonic head can be adjusted to sense a given distance as can the CRT-so I know what I am am looking at is X distance away. From the blip data-I also know what direction the target(obstacle) is located.
I will be adding a gridded faceplate to the screen which will be showing 1 square foot designations to further calibrate the unit.
 This info combined with a live action wireless camera gives me a better fell for telepresence operation, and has proved valuable in navigating very close quarters. Thus far I have limited ability to reference blip size to object size-It works to a point-small objects are just a spot, a wall for instance makes a bigger blob, but I am continuing to improve this for version 2.0.(wait-or is it now 3.0?).
  The next logical step after this will be to make the screen an LCD output device, but for now the CRTs are cheap(this one in the video was 14$ brand new in a box), getting them connected is pretty easy and they can serve lots of other purposes. They are also just incredibly fun to play with.(I made a pong game on one for shits and giggles) I have been driving the robot around with this thing about a week now, and am really getting use to the screen/robot relationship, and now fully trust what I see on the screen vrs. what I see on the camera video monitor. The scanner head is too big also-But I am making it less that half its current size as we speak. It may also be useful for more than robot building later, but thats yet to be determined(more apps for that!) While I will not be receiving any Emmy awards for my videos, I hope you can kinda get the idea of why and how I am doing what I am doing. I also plan on trying this on my other platforms including the robot boxers. A good time is being had by all, thanks for looking.........
