HuskyCaucasian Posted January 5, 2009 Share Posted January 5, 2009 I had to share this with my fellow tech geeks. (move this to a more appropriate forum is needed) Ok, first the lead up.... Recently we were undergoing some HVAC upgrades and we noticed that half of the offices were not getting ANY air through their floor vents. hmmm..... apparently it's been this way for a while AND NO ONE NOTICED!!! Well, anyways.... the duct work runs UNDER our concrete slab, and the HVAC guy and I hypothesized that maybe one the ducts under our slab had collapsed during some local flooding this past fall. The hypothesis is that the pea gravel found a hole and filled up the duct... or even worse... it's completely collapsed in on itself. Not good. Anyways... moving on. We brought in a guy to run a camera through the ducts to find the problem. Well, due to the curves and bends in the ducts and also the width of the duct, the camera snake would coil up or get stuck. So, that option was out. Next the reason for this post: The HVAC guy brought in his son's R.C. Racing car. We mounted the church camcorder to the an R.C. car chassis, we rana simple RCA cable out of the camera and plugged it into a TV outside the ari duct.... and away it went. Through many struggles and with great effort, it finally made it father than ever before (close to 40-50 ft).... only to hit a bend that makes a 45-90 degree turn, with a lip and going up hill. Experiment over. We couldn't do any further. We gave up. I tied dropping the camera through a vent, but that couldn't see anything.... and in the process accidentally knocked my cell phone down the airduct to never be seen or heard from again. Oh well. Below are images of the makeshift Upuaut and the display monitor. Quote Link to comment Share on other sites More sharing options...
