Re: What have you fixed lately?

Last one of my big solar lamps: Had to get the scope onto it to find out that a capacitor and the LED had failed. These were made before there were specialist chips to make these lamps so use a circuit with quite a number of components in it and two batteries. Fortunately I had traced out the circuit and drawn it up some time ago.

Very bright and stay lit all night even when they only get a small charge during the day but then they were quite expensive as I recall.

One of the rocks is looking dim so I'll need to take a look at it. Runs all night so it's probably a failing LED (out of 4)
