Something to pass the time- I needed a computer out in the shed, have no idea what for what but you can’t go wrong with too many computers!. So, dug through the junk box and here ya go- an old Celeron with Ubuntu on the wall. A bit slugish on this ancient board but it works. Of course, it’s a good 25 yards out to the shed so the wifi is a bit weak. Time for a home made yagi! First pic shows the construction, second, the finished product, it works quite well.
