I used to have a Gould 2 channel 10MHz scope which I bought in 1978. After it sat on a garage shelf for 20 years, I tried it out and it worked. Unfortunately I decided to sell it on eBay and got £24 for it. I now have a portable hand-held single channel scope that is next to useless and a two channel Velleman device, which wirelessly connects to my PC or tablet. It is OK, that is all I can say about it. I thought it was OK for £60, but did not know that Velleman had discontinued it in favour of a better model with a signal generator and USB connection.

If you want to use a scope seriously, I would not advise these sort of devices, but for the dabbler, who just wants to check a waveform or pulse timing, they are adequate.

Doddy, thanks for reminding me about Elektor, I used to read it 40 years ago. I didn't realise it was still going. I might get a copy or two to see what it is like nowadays, it was certainly better than Practical Electronics in those days.
