![RoboMow RS612 FPV with Drone Aerial
My RoboMow RS612 mowing a very small 15 x 19 (285 sq ft or 26 meters square) section of my front lawn. RoboMow FPV!
I have this section configured in my Robomow as Separated Zone A, 0-500 sq ft with a 68 ft perimeter. Theres no base station in this zone, so I manually drive the RoboMow up the driveway from the backyard using the iPhone app remote control. Unfortunately, my house is very old and doesnt have an external AC outlet on the front of the house, so I use a Yeti 400 solar generator (basically a car battery with a built-in AC inverter and charge controller) to power the perimeter wire stake.
You might wonder why the RoboMow doesnt mow the left most portion of the yard. The reason is simple: the yard is too steep there. The RoboMow can handle the incline just fine. However, if the RoboMow stops its routine in that section of the lawn it will freewheel off the stone wall! The RoboMow doesnt have a parking brake! I just get out a small and light reel mower and mow that section manually. Takes a minute or two.
The RS612 is rated to handle 1/4 acre. I personally have about .3 acres and it works just fine. It even mows around the wood piles in my backyard without complaint!

![Game Capture HD60 MacOS 2.5 Video Corruption Regression Bug
This is a software regression issue I ran into while filming my Hackintosh El Capitan to Sierra upgrade video. I lost the entire session due to this bug, so I wanted to reproduce it, find a workaround (hopefully saving other people time), and submit the problem to El Gatos dev team so they can fix it.
This video also provides a bit of a behind the scenes look at how I film my Hackintosh videos.
