My New 4K HDMI Microscope - The Tomlov TM4K-AF Flex! Set up and Test on PCBs!

[@MarkFixesStuff]

At the beginning I say millimetre instead of centimetre. The chip is 0.8 centimetres wide.

[@FireballXL55]

I would have said 8mm long.😂

[@42markk42]

You also say "Sometimes" :)

[@Lbf5677]

it sounds better to say something is 100 millimetres long

[@TheDarkHour684]

Mark, my cat loves your content. He thinks you're meowvelous

[@MarkFixesStuff]

Please tell him that I think he’s purrrfect 🐈‍⬛

[@soopahfly82]

That's an interesting thought. I have the dm202 and struggle with the board sizing. Fortunately Tomlov sell those arms separately. Also plugging it into a huge tv is clever.

[@cassiel1970]

That’s a really nice scope! It fixes all the gripes I have with mine. I know it’s not that expensive but it’s still a bit out of my price range at the moment. Maybe next year…

[@grfeld84]

"Sometimes I need to handle tiny parts!" Sorry to hear that! What a great way to start! lol

[@ludekstipal6120]

Should get one for my wife, so that she stops complaining she can hardly see it...

[@BrennanYoung]

some of us pay good money to receive those kinds of comments

[@MarbleGiant]

Either way, disappointment will follow.

[@wilsvgaddiction4456]

I handle my tiny parts fairly often. Maybe I'll get one of these to enhance the experience.

[@MarkFixesStuff]

It’s bigger on my telly

[@Vladimir-hq1ne]

Nice review! I wonder if it can use polarized lighting/accomodate polarization filter? Very useful in reading chip markings and microcracks in the PCBs.

[@p_mouse8676]

A polarising filter can help against the glare. Most of them can be turned "on and off".

[@Phil-Sands]

Ooh! I want one and at £192.00 with the discount code is great for what it does, there's a lot out there dearer for less features. Great review Mark!

[@MarkFixesStuff]

Totally agree!

[@RyanMercer]

That one is pretty sweet.

[@8Junio76]

Nice quote of Poltergeist.

[@BrennanYoung]

Good to see you again Mark. Best wishes for your forthcoming content.

[@UpLateGeek]

Good thing the HDMI output doesn't have the GUI overlay, just the camera image. I've seen a few other microscopes that for some reason have the GUI on the HDMI output as well, and I think it looks better on the big screen without it. Also I find most of the time you don't even need to see it. Only if you're changing an option in the menu, which presumably is set and forget. With those physical buttons for control, it would be better if the GUI disappeared from the main screen after some time and just showed the microscope image.

[@MarkFixesStuff]

Is one of the better ones I’ve had, and I’ve had four now!

[@MrTrafas]

Thanks for the review. I am looking to buy . Maybe I missed it, but I will ask what size screen, 8 inch or 10 inch. I'm a little worried about the image quality. Because the resolution is only 1280 x 800P. And I would also like opinions on Auto focus or manual focus? There is a considerable price difference, and the auto focus is not that fast. Thank you in advance

[@MarkFixesStuff]

Hi! Sorry for the delay, I am moving house. This is the 8 inch, I think the screen quality is really good in my usage. Autofocus seems slow if you are watching the video, but it's much quicker than manually focussing. AF is a bit of a pain if you are working, but very handy for baord inspection. I put manual focus on for soldering SMD chips and auto focus on for moving around PCBs for inspection. Hope this helps.

[@MrTrafas]

​@MarkFixesStuff So which one should I choose? Manual focus or Auto focus? Thank you very much for the detailed answer@@MarkFixesStuff

[@MarkFixesStuff]

@@MrTrafasthe autofocus, because you can still switch to manual focus if you want.

[@ajslim79]

"0.8mm wide" chip? .. Really? looks more like 8mm ;-)

[@SunDancerGE]

yeah. 0.8cm more like it

[@MarkFixesStuff]

@@ajslim79 yeah I misspoke lol 😂

[@paszTube]

Sometimes tiny parts get bigger during handling!

[@jetsonian]

I think this was answered at the end of the video, but it will display on the built-in screen and output over HDMI or USB at the same time? This is an issue I have with my current Tomlov scope.

[@MarkFixesStuff]

@@jetsonian the HDMI output and inbuilt screen both work at the same time. The manual says that the webcam function also works simultaneously but I’ve not tried that yet!

[@theforthdoctor7872]

It will be very useful next time you want to clean a dirty tool. Get a good look in all those hard to see places

[@Colin_Ames]

A decent unit for the price. Beats my $18 AliExpress one hands down!

[@jonskitch8082]

Not keen on auto focus, when you work it interferes too much. So I bought the non auto focus with larger base

[@MarkFixesStuff]

Yeah. I’ve turned it off now. Is handy for board inspection but a pain for soldering as you say.

[@jonskitch8082]

@@MarkFixesStuff yeah for inspection, it might be fine - the noise puts me off. I saved few bucks on non auto focus.

[@tdub8719]

I'm a bit gutted. It looks like a great bit of kit with good reach. Exactly what I want. But I was hoping it would come in around the £100 price. But it's a little expensive for the occasional use it would get from me. Thank you for your review and heads up about the product.

[@MarkFixesStuff]

@@tdub8719 I believe the arm is now available separately so you could pair it with a cheaper main unit.

[@tdub8719]

@@MarkFixesStuff Good, that's an option. Thanks for letting me know.

[@jonskitch8082]

In your dreams

[@Keeping_IT_Simple]

what is the small hole between the Micro Sd port & HDMI port for ?

[@MarkFixesStuff]

@@Keeping_IT_Simple That’s a reset button to set the unit back to factory.

[@Keeping_IT_Simple]

​@@MarkFixesStuff but isn't there already a reset on the other side ? Between 5v & output ? I'm talking about the unmarked hole between the other 2 ports!

[@MarkFixesStuff]

@@Keeping_IT_Simple ah I see. That’s not anything. Just a hole that goes nowhere. I guess it might be for another revision of board? I investigated and even looked under the sticker that covers the back. I did find a battery compartment for a 16xxx style rechargeable cell that you access with a screw there though. But that hole is just a hole.

[@Keeping_IT_Simple]

@@MarkFixesStuff thanks for solving the mystery of the unlabeled 🕳️

[@michaelk6957]

Is this the 8 inch screen version or the 10.1 inch?

[@MarkFixesStuff]

This screen is 8 inch.

[@fueledbyregret]

Tom Lov? You called? 😜

[@SproutyPottedPlant]

I’m going to need a much bigger screen, I’m a VIP (visually impaired plant) 🌱

"sliding our unit into the hole" sorry I'm hearing innuendo maybe even in places where you didn't mean to!!!!

Seems reasonable to me. It is not cheap nor expensive.
