And so, my brief run of bad luck in experiments with various batteries has come to an end. As usual, I ordered the battery for a specific purpose, but read on to find out what it was and about the battery itself.
DS203, a decent, compact, simple oscilloscope at a nice price.

Another instrument joins my collection :). I've wanted a toy like this for a long time. It's hard to call it a full-fledged oscilloscope; it has its drawbacks, but its low price more than makes up for them. This model was reviewed quite recently, so this review will just add a few details and my comments.
