Beware!I ordered the complete kit version on 10/25/10. It never arrived nor did they reply to my Emails. As soon as I filed a Paypal dispute on 11/16/10 they refunded most - $1.99 USD short - of my money.CR
They're quite useful for auto purposes, I managed to sort my injector timing with one
What's your opinion on the PC-based ones, I mean the inexpensive kind, not the multi-thousand dollar rigs
I don't have a scope, and even have been thinking about checking the forums and google for any particularly good microcontroller-based projects. Seems a natural, so I have always assumed there would be a thousand poor implementations, but few halfway decent ones.
That being said, I've even been tossing around the idea of a basic logic analyzer/oscilloscope design that uses Arduino (easy enough, plenty of inputs, fairly fast) with the TVout library. I don't know about others, but that lib provides a very low cost, high-complexity display option that most of us have already.. many of my current projects use TVout because portable NTSC displays are readily had from broken portable dvd players, if not the good ole family tv. I would love to be able to flash the boarduino with software making it a logic analyzer/scope when I needed it, and then reflash the chip for other purposes after I was done with the need. No need to dedicate hardware, except for the amplifier circuitry and such. Given the settle time of the a/d and all that, I suppose it might not be fast enough for fast signals, but audio and logic ranges ought to be well within sampling range.
