Adrian SanabriaAt RSA, when you’re at one of the main hotels, vendors leave marketing stuff at your door or in your room.
Cisco distributed full-on video players with built-in li-ion batteries and I just now found time to dig into it.
Can I put a different video on it? Why, yes. Yes I can.
Alright, let’s start tearing open this paperboard glue sandwich and see what’s inside.
I don’t know what I was expecting, but Antarctica wasn’t it.
Pretty much what you’d expect, SBC with a lot of hot glue, a speaker, buttons, and the USB port.
The magnet on the right hand side turns the device on and off when a corresponding magnet in the cover makes contact with it.
OH, and the li-ion battery that absolutely should not go into the trash and will burst into flames if punctured.
Im betting 99% of these Cisco video pamphlets, like most disposable vapes, went straight into the trash.
As for the chips, the v100 is likely the SOC, the Kioxia is 256MB flash I think, and the ESMT chip is handling audio?
Just guesses from some quick searches
After some struggles to separate the delicate TFT from the SBC, I managed to free the board entirely, revealing the manufacturer and product model!
Some searching suggests that these things cost $10-$20 apiece

And this is the end of the exploration for me, I’m not hardware hacker enough to access the firmware, mess with it, or to get Doom running (which I’m fairly certain would run just fine on this hardware)

@sawaba I cannot imagine a better way for Cisco to spend their money, but thats either because I'm not very imaginative or because Cisco isn't paying me the big bucks they pay their marketing department.
