I'm the guy who donated the Sony GPS! I've since discovered that it's the electrolytics on the display board that fail, resulting in "Dead Screen Syndrome" & not a loose flat-flex.

[TechGuyCharlie]

I'd love one of those single board computers!

[toddberg]

Well Dave, follow the picture on the can! Spray a drill, give 'er a dunk!

The transistor is a germanium PNP designed for low frequency amplification.

What do I win?

"Hello, LattePanda customer support. Is it plugged in? Have you pressed the 'on' button?" ;-)

Sony GPS and HP power supply - beautiful. It looks like the Panasonic Toughbook didn't survive wartime service.

Yeah, I have the 4GB RAM/64GB LattePanda. I've found that you need to use a 3A power supply for it to run stable. I've also had to add a low profile heatsink to the back for it to run cooler. Other than those quirks I've been pretty satisfied with it. Btw, the LattePanda team has made a power-on-plugin BIOS that you can flash so that the board powers up when you apply power to it.

I see the problem... It's got a bit of malware called win10. Clean that up and you should be fine.

[FurEngel]

I am still waiting for Dave to open one of these random packages only to have a kilo of cocaine fall out onto the table.

[Wineman]

Damn I'm watching mailbags from 5 years ago.
These videos hold their value pretty good don't they?
Thanks from the states, I took basic electronics design and programming in the Navy (96-2000)
Long ago but I can follow along with most of the circuit explanations, I missed alot changing my field so YouTube has filled the gap in a very satisfying way.
Thanks again!!!

The little Windows 10 board could make a fun "hacker's laptop" project.

I've lost count of how many times I've heard 'We're in like Flynn'—in the one video.

At 2:50 you can see the "Moskva 1980" text below the tuning dial. As pointed out by someone else it means "Moscow". If you notice the image to the left it is the logo for the 1980 Moscow Olympics. At 14:00 the sluggishness might be due to Windows checking for, and downloading, updates in the background. As to having to use a button to power on you should check if you can get in to the BIOS of the unit. If it is using a standard type of BIOS there will be an option that says whether the unit should power back up after a power loss or stay off. At 34:30 the power supply looks like one that would be used in a rack. The rack would provide the cooling so there would be no need for any active cooling within the supply itself.

[TheUbuntuGuy]

Those staggered DIP packages are properly called QIP (quadruple in-line). The SIP variant is called ZIP (zig-zag in-line).

[DavePoo]

34:40 - those power supplies are designed for the system to have a bunch of hot swappable fans that suck air through the front of the sever case and out of the back. So all the air flow would have to pass over the power supply.

As I said before, my favourite segment is fundamentals friday. :D

[AureliusR]

Holy CRAP. The version of the LattePanda that Dave has retails for $139 US!! Why on EARTH would you buy that at that price point?

[SvenOkonomi]

That knife should be made mandatory for every youtube unboxing ever.

[thenaimis]

radio was obviously made to commemorate the 1980 Moscow olympics

[Seegalgalguntijak]

The audio player from Creative that came before the iPod was called the DAP Jukebox, or something like that. It came with up to a 4GB hard drive, and then there were instructions on the net about how to upgrade it with a 20GB 2.5" laptop hard drive in order to get more storage out of it.

[FortyTwoAnswerToEverything]

That LattePanda looks like it would be a great project for a custom car computer hidden away behind a touchscreen monitor that fits in the double-din opening, replacing the factory radio altogether.
