I followed this tutorial and now my VNA won’t turn on. Pls help

[@johnwest7993]

And here I was thinking you were the perfect RF engineer. But it seems you're only close. :) This is why I do everything in my lap. Then it can't slide off the table.

[@radio655]

Ouch, that was painful.

[@ve3enx95]

LOL! This is when I thank myself that my workbench is such a mess that I end up sitting on the floor and working there... :-)

[@daviddevillers6790]

whoops! not sure how you got footage of my desk last week, but thanks for posting. hang in there!

[@joesmith-je3tq]

Some damage but nothing major. I finished up the review last night. Should have it on-line soon.

[@wktodd]

Yep, that is very familiar 8-)

[@jevfrocleblando7519]

A lot of us know the feeling... my sympathies. I think that's why the tactile switch on my VNA doesn't work anymore

[@patriceh6316]

THIS is a perfect example of the Murphy's Law!

[@dreamvouyer67]

Dangnabbit! I hope nothing broke Joe...🙏🏽🙂

[@joesmith-je3tq]

Nothing too major.

[@dreamvouyer67]

@@joesmith-je3tq Good to know...it looked like some important or at least sensitive equipment....🙂👊🏽

[@ZlayaCo6aka]

An appropriate event for George Carlin's "seven dirty words."

[@HG-nv8fk]

Hey don’t you just hate that when it happens. Man I feel your pain as I have done the exact same thing with the exact same response.

[@KeanM]

This is even worse when you do it in front of a client. Hypothetically of course...

[@MrReinerMSchmidt]

Happens to the best of us

[@metallitech]

That happens to me once per project, and it makes me feel like smashing it up.

[@ruhnet]

Hate it when that happens!!

[@jfcrow1]

Yeap. Happens to me all the time.

[@electricalscience3354]

So a lot of pain there...

[@LawpickingLocksmith]

Oops. Just start again!

[@vladimirkisel7291]

Need say: "Blyat!" and all setup will be restored. Millions russian people every day say this, it really work!

[@cannesahs]

I hope nothing broke

[@joesmith-je3tq]

Just some minor damage was all.

[@vincei4252]

RIP

[@rufflefpv]

Ok, at first I thought you'd look how nanoVNA fares against cat IV meters. I wasn't far off

[@zeljkoadzic1692]

Oh no ;( plus4 is good?

[@joesmith-je3tq]

Depends. I'll cover some of what I have learned in my review of it.

[@nikmilosevic1696]

Yup, hate when that happens!

[@sepertude]

Are you gonna test new Megger multimeter? Would be nice to see how good it is... Set funding so we can donate so you can buy it..

[@joesmith-je3tq]

Their website was down when I checked. Looking elsewhere, seems they sell products for electrical work. I didn't see anything for electronics. It looks like they sell some rebranded AVO410. For $150, you get 6000 counts, half percent and a shared V/uA jack. There's a few YT reviews for their products. One shows an AVO835, which looks a little better. $270 for a 10K count, separate jacks, AC+DC. The front end looks typical. From your post I am guessing they have something much newer.

[@Stelios.Posantzis]

What's the damage? Any opponents of wireless charging or wireless mice for laptops watching, well, now you know why...

[@joesmith-je3tq]

Lost a cable and bent the USB connector on the Nano. It had to come apart but nothing major.

[@Stelios.Posantzis]

@@joesmith-je3tq So mostly the aggravation and the time wasted ... If I could count the number of times I had to get up in hurry from my seat and in the process my foot/leg dragged the computer's PSU or other cable with it... accompanied with infinite aggravation and feelings of helplessness and utter stupidity every time (which is why I now hate devices with an L-shaped power cable plug). I think I've developed a "fear-of-getting-up-in-a-hurry-and-dragging-my-pc-along-with-me" syndrome as a result.

[@tinygriffy]

When will we see the results of your experiment ? Did it survive the drop ?

[@joesmith-je3tq]

There was some damage.

[@supercompooper]

Ahh the quadravoopalizer polarity!

[@BVN-TEXAS]

Done that before when the dog ran by and hooked thr cables.

[@SeAfasia]

It's heart....

[@amirb715]

now you made me wanna buy a nanovna v2+ and break it into pieces. why???? ;-)

[@worroSfOretsevraH]

xD

[@SuperBlackReality]

F

[@joesmith-je3tq]

5 X F

[@barryg41]

Been there Done that! 🙄🖕😤🤐

[@chefbink61]

hehehe that's one of my tricks

[@qbqbqdbq]

you hate to see it

[@TheOpticalFreak]

😫🤦🏻‍♂️
