You think a $2 multimeter is bad?
A review of the Kickstarter & Indiegogo Vion bluetooth multimeter that promised the world.

Clearly this crap  was  designed to scam people into thinking that this device  would have the  same accuracy  and resolution of  a name brand  Multi-meter.


They should have  done  a marketing  wank video on testing  the voltage  on the cells on one of those solar roadways  8)

I was curious about how bad this was, thanks for looking. Would've loved to have seen if it held up to higher voltage, and higher frequency, AC. I bet you can get it to let the smoke out then.

This is a 50+ device? LOL! TBH it's better it doesn;t try to measure current. IMHO no DMM without dedicated current input should.

The main purpose of this DMM is Go Show young students how to run a kickstarter the wrong way.
And how mit to design a product.

My theorie is that this DMM is a theoretical project of a groop of design students which got build in reality.

EDIT:
I know why this DMM isnt working.

Really enjoyed the video.   Too bad that transient generator you salvaged couldn't have found a spot in the video.

Nice video!

Not sure if you spotted this, but at timestamp 30:18 it seems to me that an EMductor, err...I mean inductor, is not soldered on its pads... (I guess part of the antenna matching network)

cheers :)

It's a blatant rip off, trying to be a simplified Mooshimeter - (I think it is the original) Bluetooth+Smartphone app 2-ch 24-bit A/D multimeter. That Kickstarter, which went through FCC and 61010 approvals, was many years ago...

I remember some of our undergraduate engineering team projects, and there would always be a guy on the team who would think of things like this.

Engineering is about finding elegant solutions to problems – with simplest often being better (not always). People who just "don't get it", seem to think it's about features. At minimum, this thing would need semi-accurate DC volts and resistance with an OLED screen and wireless charging to even make it slightly useful. Having to pair it to an app just makes it too much of a pain in the arse.

Undoing a screw to charge a device? What.

I fail to see any advantages over the common "multimeter built into one probe with display" type multimeters.

Next up on Kickstarter, by the team behind Vion: a digital tape measure with a single LED that turns either red or green, depending on whether the thing you're measuring is of the correct length or not. Affiliate links to trusted "enlarge your penis in 5 minutes with this simple trick" partners might or might not find place in the accompanying mobile app.

Its the same idea, but hardly a blatant ripoff. Almost nothing in the physical design or look and feel of the app is the same.

Anyway, it looks like mm have stopped production, its marked as sold out on their page and "obsolete" on digikey. I have one and its very useful for remote logging, but not day to day use.
Having a rechargeable version would be good but: it would cost a lot more, and would have been hell to pass certifications (as they stated any cover or port protection has to be open during high voltage testing, this is why the SD slot had to be covered up).

Wow they just re-invented a Duspol !
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

...but with no screen, an awkward cable, bad battery, and unreliable measurements.

Too bad they seem to have abandoned it, two channels for V, I is very handy.
pic related, wireless multimeters are useful for measurements in unsafe or inconvenient areas. I prefer something hands-on though.

This looks like fraud...   the objective could have been to get the Kickstarter/Indiegogo money and run!

Nah, they manufactured something and wrote half an app.

Never attribute to malice things which can be adequately explained by incompetance.

I seriously doubt that they were out to scam or defraud anyone otherwise they would not have included their names and faces in the marketing material. In many aspects the final product does not even closely resemble the device that they originally promoted and I would speculate that perhaps they had internal conflicts, this would explain all the delays and uncertainty.

I feel the people calling fraud may be the same kind of people who produce these kinds of products as they both grossly underestimate what goes into the development of a successful product. Failure is not the same as fraud.

The real deal for mains related work. And it has a proper CAT rating (CAT IV 1000V).

Let's call it croudfunded education. ;) The backers help some team to gain first experience in designing and producing a product. When the team just managed to build an arduino blinky, it will be also educational for the backers. ;D
