Why do some people see #TheDress as blue and black, and some as gold and white?
If you are one of the lucky ones to own a 3D Printer then this STL (STereoLithography) file template might be worth looking at as a toy model of a Toyota 4 Cylinder Engine. Completely print a fully rotating model. Working crank, pistons, and valve train. The valves open and close!!!. It may not be the most exciting engine but its the only one I had in my garage. Great
With all the power cuts recently thanks to Eskom and their “Load Shedding” I decided to re-use my old APC UPS to power something other than my computer and monitor. With the Multiplug plug hack I connected the conventional “Kettle” plug cable to an ordinary household 220v multiplug adapter. So far I was able to power my Telkom ADSL router, 8 port switch, PlayStation 3 and even a hair clipper. !!!WARNING!!!
