    Dave caught up with the designer of the Cleverscope, Bart Schroder at the Electronex show. He gives us some history on the company (from New Zealand) , the scope, a quick on the spot teardown, and what latest scope design he’s working on.

    • Hi Dave!

      Thanks for the videos. I’ve been watching for a long time, and I’ve seen ‘em all. I have one piece of advice, now that you’re doing this full-time and doing more interviewing. Try not to say “yep” when you’re doing an interview. Also, when someone is talking about some item or something you know about don’t cut them off saying that you know about it. Remember that you’re not talking to the person just for yourself, maybe we would like them to explain it! :) By the way, this isn’t just about this interview…

      Thanks! Keep up the good work!

    • Wasn’t Cleverscope a Circuit Cellar contest winner years ago? I thought Bart would mention that but maybe I got my memories mixed up.

    • What is the economics of a scope like CleverScope? I look at the price and well, seems like one might as well buy a regular scope. I thought the idea was to use PC hardware to reduce cost but, at those prices, the benefit is not immediately obvious to me.

      • Just to be more concrete, compare the PicoScope 2204 to the Rigol 1052E. The PicoScope is $371 to the Rigol’s $399. 10Mhz bandwidth to 50Mhz respectively. Now, the PicoScope has an AWG but, meh, if your primary need is a scope.

        The PicoScope 2205 is $486 but still only has 25Mhz bandwidth (same AWG). So I don’t know. The video laments about “cheap chinese scopes flooding the market” but can PC scopes really be significantly cheaper than regular scopes for comparable specs? Seems like it should but not seeing it. Maybe I’m just not Googling hard enough.

      • Correct, they are not economical nor can they match the bang-per-buck of the low cost bench scopes.
        They are an entirely different type of instrument, so you are not comparing apples to apples.
        They should be used for different things. PC based scopes are good at higher resolution (try buying a >8bit bench scope) and data logging, and the power that a PC brings you for logging and analysis.
        See my video on PC based scopes:
