RMweb Gold 2mmMark Posted November 8, 2019 RMweb Gold Share Posted November 8, 2019 Looking for opinions, views and maybe personal experience of the small hobby scopes, like the JYETech DSO-SHELL DSO150 and similar. I'm interested to see the various waveforms that different controllers generate, more out of curiosity that anything else. Mark Link to post Share on other sites More sharing options...
ejstubbs Posted November 8, 2019 Share Posted November 8, 2019 FWIW I bought a DSO 112A off eBay ready-built, I couldn't be bothered to assemble one. It works OK as a 'scope, but the internal battery wouldn't charge via the micro USB port. I complained to the vendor and received a full refund, didn't even have to return it! I now use a small USB power pack, of the kind that are sold as backup chargers for smartphones, to power it. I'd have thought the DSO150 should be more than adequate for observing controller waveforms. Link to post Share on other sites More sharing options...
sharris Posted November 8, 2019 Share Posted November 8, 2019 It's fun to do this kind of thing yourself, but if your curiosity can be sated with a visit to https://www.scottpages.net/ReviewOfControllers.html it might save you a few pennies. Although, looking at the one you suggested, it's not that many pennies for the scope. Link to post Share on other sites More sharing options...
RAF96 Posted November 8, 2019 Share Posted November 8, 2019 Or if you have deep pockets try Pico-Tech USB scopes for your PC/laptop. 2 Link to post Share on other sites More sharing options...
RMweb Premium TheQ Posted November 8, 2019 RMweb Premium Share Posted November 8, 2019 I bought a small Farnell dual channel Scope at a car boot for £5, there was a couple there selling off their Dads old TV repair kit.. all the stuff I got wworked OK.. 1 Link to post Share on other sites More sharing options...

My late uncle was a TV technician for ILEA so he'd have had a scope but perhaps a bit bigger than I'd have room for! Link to post Share on other sites More sharing options...
RMweb Premium Nile Posted November 8, 2019 RMweb Premium Share Posted November 8, 2019 If you just want to look at controller waveforms (fairly low frequency stuff) you can use a PC and some software. eg: https://windowsreport.com/oscilloscope-software-pc-laptop/ Link to post Share on other sites More sharing options...

If it were one of the old Valve powered ones I started on, it'd be a pretty good heater as well. The Farnell is all transistor, Now have sat beside me at work, a Ohm meter, Voltage meter AC/ DC , Current meter, frequency meter, temperature meter, capacitance meter and a Scope. all in one Box with an 8.5Digit display..

RMweb Premium TheQ Posted November 8, 2019 RMweb Premium Share Posted November 8, 2019 405 lines was still the only TV in some parts of the UK until the early 1980s.. Link to post Share on other sites More sharing options...

I bet it has a digital clock too! I used to use a logic analyser a lot in the late 80s/early 90s. I can't remember now for sure if it was a Tektronix or HP one (probably HP, my boss at the time liked HP stuff), but I do remember it had a built in Connect4 game for when you got bored of analysing stuff. 1 Link to post Share on other sites More sharing options...

And a.c. coupled so you won't see the d.c. component of your controller output. Link to post Share on other sites More sharing options...
