PTZ not working in Blue Iris 5 with Yoosee camera

I recently received a new PTZ  camera (works with the Yoosee video application)  I ordered the camera from AliExpress. I got the video side working fairly easily with the Blue Iris camera app, but had some real difficulty getting the camera to pan/tilt/zoom. In an associated page I will show you what I did. It is quite easy actually.  You can read the details  here .

bought a new “cruncher”: AMD RYZEN 1700 and AMD RADEON RX 580

Yesterday I bought a new “cruncher”:  a Dell AMD Ryzen 7 1700 with an AMD Radeon RX 580.  As soon as I got home I removed Windows 10 and installed Ubuntu 16 (tried 17 on this node but had issues).  This PC required the installation of new AMD GPU PRO driver support because Einstein@Home did not recognize the onboard GPU.  There were errors in the AMD procedure which I will address later in a more detailed page on this website.  Now for the “bad news”  Once the drivers were successfully installed Einstein@Home is reporting the GPU as being a 480 and not a 580.  I will have to look into this and depending on what I find contact the store to see what is going on.

Completed build of 3D tank

Finished the build of the 3D tank.  It took longer than I thought but here it is.

The main differences between this tank and a previously PS3 controlled tank are:  Its body was fashioned from CAD designed 3D parts giving it a more completed look, the headlights do not require their own circuit board (the ground and positive of the LEDS are plugged into the signal pin and ground on the ServoHAT which has built in resistors for each of the 3V channels, and the video provided by the on board camera did away with the Linux Motion app in favor of “ffplay”.  ffplay provided for a simpler integration/configuration with less latency as seen in this video.  Also ffplay is started with this application.  There is a gotcha however.  If you want a larger “TankEye”  change the window size in the application code which triggers ffplay.  If you size on the go it locks up the video feed.

You can see more of the 3D build here if you wish.
