Which reminded me of the osziFOX pen-like oscilloscope from the late '90s:

I have one, but have barely ever used it. IIRC the display was too small to be of much use, and the wired serial link & PC software wasn't much better.

 

 

The IkaScope seems rather expensive, though.

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

What do you want to say with this?

Why would such a toy be interesting at all?

It's EUR300 For that price you've almost got a 4 channel Rigol, with better specs in almost any category except size. But the size of the Rigol (or any decent scope) is mainly dictaded by the room needed for a decent user interface.

 

Any scope with less than 2 channels is a toy.

If you want to design anything with electronics you NEED to compare input and output of a circuit for a decent overview. Even for a simple circuit such as a single transitor amplifier.

 

The only use for a single channel toy is maybe in te repair buisness to do quick checks if some part of a circuit works at all.

I might be considering buying it if it was < USD 50 for some quick checks on signals and I'm not in the mood to walk to the cupboard to get my Rigol.

Fun toy as an "extra" gadget, but not able to replace a normal scope.

 

And what is the use of wireless if you have to hold the thing in one hand, and control the gui with the other hand ???

It does add the extra nuisance of having to recharge / replace batteries.

 

Some of the DMM's & USB Scopes are (slowly) getting equiped with Wifi / Bluetooth. which can be very usefull for isolated measurements or hard to access places.

 

Sorry about the rant, but if I see their slogan:

i get irritated. They seem to think that no user interface is better than a well designed UI where functions are accessible by buttons. Yuch.

Silly hype gadget toy.

Mostly the fact that they seem to be claiming some great leap of innovation - but, really, it's just an update to an idea from the 90s

I would (poteitally) find it useful for quick checks, fault-finding, field repair, etc

Indeed - my point exactly.

I don't entirely agree - see above

There are plenty of cases where just seeing one signal at a time is sufficient.

Especially in the above-mentioned use cases.

 

Probably one of the most frequently recurring examples here would be to see if there is any signal at all  at a pin.

 

 

EDIT

Agree entirely on that one!
