The cutouts around the edge of that mesh appear to match up with the fan mounts and the power connector, almost like it was supposed to go over there instead. And in case you haven't heard, you might be interested to hear that "Warranty Void If removed" stickers have been ruled illegal over here in the US .

"hit any key" needs to be on the RS232 port, not a usb keyboard. Standard u-boot linux bootloader.

[mikeselectricstuff]

"Press key to stop boot" will be looking for serial chars, not usb keyboard.
Hardware links will be mostly so the software can know board rev and deal with any changes over time with a single Fw version

“Déjà vu review” = Dave made this video and simply “forgot to publish” then a few weeks later he started his research and recording all over again and started having some flashbacks... checked his hard drive and the video was all done ready to go!! Hahahaa one of these moments... =]

"... That makes it look, I dunno ... Meshy." @3:27 is such a wonderfully quotable line.

Thank You EEVblog Keep up the Good Work! :)
Thumbs up Indiana USA.

My best guess is the resistors in hw-id is for the software to read the board revision if something changed etc - not to lock down the firmware. I still think you can purchase software option codes and enter and it would unlock that way.

Lol, so i'm guessing Rigol sent dave the scope? of course they sent the top end model, so he can't use it to figure out how to hack a lower end one :P

[DodgeWatt]

I love that feeling of voiding the warranty!

[voltlog]

I wonder if a hack for these will ever be published. After-all they are more expensive so not as many people can get their hands on these to start hacking.

Should have a small desk fan to keep airflow on the heatsinks when the back is off, just in case..

[viperidaenz]

That hardware version is probably just that. The hardware version, so they can run the same firmware images across multiple scopes, or at the very least the same firmware for different PCB versions of the same model.

I like the black color more shown on their prototype machine.

[p_mouse]

Even at the PSU you can see they planned to use an extra fan. There is a second fan connector.

10Gsamples/S for 500MHz seams quite a lot, could they have a 1 GHz model on the way?

[iamdarkyoshi]

Adda fans are what I see in OEM PC PSUs and I've like never seen one fail...

[tocsals]

Looks nice and clean. I dig the black development prototype!

What is the reason FPGAs need all those different voltages when typical CPUs don't? Possible Fundamentals Friday episode?

[edwitte]

Try placing a piece of Kapton tape on the shiny tin cans. This will allow you to 'see' their temperature with your thermal camera 😊

Still only 8 bits? You would think that they would be moving towards higher vertical resolution by now. Not everyone works in a digital world.
