Looked good here even at a humble 480 resolution. The zoom detail was very good, as was the full video which must have taken a long time to put together.

I don't understand your disdain for the LCD screen? I have this DMM in my hands right now. My eyes see it quite differently. Bold segments that are easy to read and clear as day. Bright and spacious display with space to spare. Amazing considering how small this meter is. It's not OLED or EBTN but it's damn good nonetheless. Maybe you acquired a dud. Even good batteries are cheap as borscht nowadays so battery life really shouldn't be a factor. What's the deal? I think it's a step forward unlike some new meter displays that seem stuck in the "90s. Btw, the meter ships in a nice OEM case. More new meters should do the same!

On 4K you can really see where the camera focuses. This is not that apparent in 1080p.
The camera seems to have a small depth of field. Maybe decreasing the apperture size will improve this.
But this is really just nitpicking and loads better than 1080p. Love the sound quality too!

watching your old teardowns after watching this 4K one is like day and night. the video is so crisp and sharp

Watched in 4K on my 4K TV, looked great. Keep it up pls.

The soldering isn't actually too bad, when you consider it's probably RoHs solder.(no lead). That type of solder is not as shiny as Lead/Tin solder, and it requires higher temperature. If you're planning on using that meter, I would highly recommend re-soldering the ICL8069 voltage reference. Even though it's probably soldered just fine on the other side of the board, I never really trust those vias on double sided circuit boards. If you flow solder on the top side of those boards, it would help ensure more consistent voltage readings.

Superb quality video from your Sony 4K camera Dave. The audio is a bit 'bass light' but nothing you wouldn't expect when you're a reasonable distance from the camera.

4K vs regular HD all looks the same on my 4K smartwatch anymore. My eyes must be going. That additional unmarked chip looks like a popular philips segmented LCD driver commonly used in automotive it has the resistor and capacitor pair next to it that select oscillator frequency for lcd scan.

[Dennis-mqor]

Yes the video quality is excellent.
I do not have experience with LCDs, but believe they are ac driven and the phasing relationship determines which segments turn on. If that is true, then wouldn't it be possible to switch from the negative view to the positive view by reversing the phasing?
I like that dark background for inside work, and it would be neat to have another switch, (or an ambient light sensor), that would switch to the positive view and switch the illumination off when the meter was being used in a bright area.

I don't know if it is better but your video quality is REALLY GOOD. Thanks for your work!

Great review and teardown, the 4K looks fantastic. I don't have a great audio setup (a dickey 30+ yo boombox wired in) but there was nothing bad in the sound. The icky soldering did show very clearly though. I am very curious as to why that transistor didn't have any solder on two legs (at least on the topside) but if it wasn't worth pointing out then I'm going to guess it's not a big deal for whatever reason.

Good review. I might pick one up just to have a bang about meter instead of carrying my Fluke everywhere.

The 4K was really good. You could even see your reflection in the solder joint when you did your first zoom on the ICL right around 2:45.

[JtWhissel]

I always watch you on my 4k tv. Yea it looks 4x better! Went back to the video on my phone to let you know it's worth it thanks for uploading it to 4k

[levbobrov]

I definitely hear that the sound quality has changed. Not saying that it's better or worse, but immediately after the video started, I was like "there is something different about the sound".

[DanOConnorTech]

It might be something with my individual vision, but a 1080p60fps looks better to me than 4K. Maybe because my laptop screen is only 1080p. Still, the 4K was excellent. Thanks for the teardown and enjoy the new camera!

[viniciusvbf]

Nice video! Incredible camera.
An interesting mod would be using a 18650 battery and adding a USB charger.

[flomojou]

1080p looks amazing, very clear and easy to see. The only limitation is these old eyes :-)

[HenriqueLatorre]

Thanks, I was looking like crazy for you back to back transistor zerner video and couldn't remember which one

I was wondering if that relay drew current all the time or not. By the way Dave, the newer 8009 does have the NCV in place of square wave generator and also has temp probe - unfortunately the 8009 still doesnt have the missing ranges you spoke of. If they added the ranges, replaced the power hog display with an updated LCD one, rework the tilting bale maybe they could keep the push buttons and with these mods have a good upgrade model from the 8009. I have an 8009 and its been great, had high hopes for the Q1 but looks like they didnt think this one through, the design just isnt practical in its current form.

The relay is a great idea Mate, think about it. There is no parasite drain and you can have an auto shutdown.
