Re: Oscilloscope Kit from China
Les -
I've been breaking open dead laptop batteries and re-using the 4v Li-Ion cells inside, without any of the clever gubbins. I've apparently been charging them wrongly (I've used a small constant current, I thought to be safe) and they still work fine for my purposes (instrument supplies, a stand-alone 10W speaker-amplifier, etc etc). I work in a university and keep an eye out at the battery recycling bucket. Perhaps you could get lucky at a laptop / phone shop.
On-topic, I like this little scope - I had to wait until I was well in my 20s before someone threw a huge, ancient, valve, single-beam solartron in my direction. I can see it would be really handy for vehicle stuff, for which I hang onto an old Scopex single-beam which is more-or-less portable.
