VERY cheap USB oscilloscope

Just spotted on eBay - a USB oscilloscope box (two channel input) for £17

Ships from Hong Kong, but at that price might be worth taking a chance. I'm wondering what the snags are.

Answer - max frequency is only 3khz, which I would have realised if I'd read it carefully. Not a huge amount of use.

Today's charity shop bargain...

...was a teeny infra-red controlled model helicopter and controller - for a fiver! They originally had it for a tenner (and I've seen them on sale new for about £18), but the shop was doing a half price sale today. It even had batteries in the controller!

It works very well, but my impression from playing with it a bit is that it's a VERY good thing that nobody is asking me to pilot helicopters for a living, I suck big-time!

This is the same model, I think

Rather pleased about this one!
