What a coincidence! I just added a log entry with some musings about the extraordinary imperfections of a Chinese LM2596 DC/DC converter, and then this picture appeared in "My Feed".

It probably has a very low quiescent current.

Cheap module ordered online?  I have started putting simple SCR/fuse crossbars after these converters because I don't trust them :-)  Even with the added parts, it's still cheaper than a module from a reputable supplier.

The lowest! That's an eBay order for my overhead LEDs / camera rig thing, since the LEDs get a bit warm I want to be able to dimm them.

Are you going to control the brightness by inserting and removing that piece of paper? ;-)
