Well, I did wanted you to troubleshoot that firewall, but it was hilarious!
Good work!

"Coil" in BGA chip is just a die filler stopper, so underfill does not go outside in routing area.

[Diggnuts]

The fit probably is a bit loose so you can fit a batteriser to get 80% longer lasting light...

... DUCKS....!

Dave, if you take that torch down to the local bait and tackle shop I would bet you can find a good clip on swivel that will fit that ring mount on the cap. Then you can hook that to the key chain.

My guess at the reason why that chip was destroyed so easily was to protect the private keys that may have been stored in it. If that device was used for authenticating to a high security network, you may be able to extract the keys and impersonate the device potentially by accessing the chip directly. The choice of BGA was probably also chosen just to make the contact points on the chip more difficult to get to, so you can't probe it while it's running.

Hey Dave! Another Lithuanian fan here :)

[Esthreel]

Ha ha Lithuanian sends stuff, fills the empty space with candy, not packing peanuts :D

[technodaz]

Love the little torch shame about the battery usage on its highest output, if only someone would make a device to extract more power out of these

That Check Point flat pack is a custom ASIC which is needed for stateful firewall and any UTM features it may have. I didn't check the specs on that check point model. UTM for those new players = Universal Thread Mitigation. A term coined for devices that perform multiple security functions such as firewall, antivirus detect/block, intrusion detection/prevention, web filtering, etc.

Hey Dave love the mail bag's always a treat. I've seen similar things on other secure devices. once assembled the only way to see what's going on inside is to destroy it. I look forward to the scope repair/attempt to repair and the handicam retro teardown don't keep us waiting too long ! greetings from RVA in Murica by the way!

[tubical]

Repair that FLUKE, Dave, it deserves that:) !

[voltlog]

Dave, you just invented a 2 second ic decap technique

[stonent]

If you can get the cap off the heat sink, I'd still be curious to see what it was.

[rationalmartian]

A good tip for the split ring on the torch is to use a small fishing split ring and a swivel, with a larger split ring on the other end.
Care of my owd dad.

[Mobin]

Why did you break that Firewall? 0o
It's worth like 500$ on ebay.

[talaminia]

I have that exact same Sony camera somewhere lost in the attic except its the NTSC version and it still works. I remember that brick of a battery charger, you had to slide the battery on it and the battery could easily fall off. Brings back memories.

[VECORlt]

Lithuania represent! To be frank its rather amazing to see stuff travel to Australia, so I can just watch it get taken apart sitting here in Vilnius.
The dude in the box is the famous Lithuanian painter/composer M.K. Čiurlionis, you can see his painting on the cover.

[bobbailey]

The AAA battery has to be a bit loose in that you can fit a 'Batteriser' in there and make the battery last a gazzillion times longer :-)

[GedasBR]

Lithuania!!! proud to be mentioned on this channel :)

[Polaventris]

Very close to the Sony DCR-TR7000E videocamera I have. Although that is Digital8 already. It was quite fancy thing and quite expensive back in the day!
