Sammy Kamkar Is a legend. First thing i seen him talk about was opening ppls garage doors with a barbie personal messaging device. Sammy 4 President, 2024!
21:15 so this is true for inductors, technically it's true to a much smaller extent for any electrical component, but with capacitors the dominant means of sound production is actually piezoelectric effects. the dielectric of a ceramic capacitor is crystalline, and the crystals will expand and contract depending on the voltage across them. mainly sharing this because the speaker has this wonderful spirit of curiosity about them that makes me think this will be appreciated, but an interesting semi-practical takeaway from this is, the sound waves come from variations in current passing through them, while the sound coming from a (ceramic) capacitor come from variations in the voltage difference across their terminals. in theory you could probably do some interesting things by measuring phase differences between these signals to learn a bit more about what's happening in a circuit (although i think most of the information you'd get is just details of how the power supply is implemented, and i can't really imagine how that level of spatial detail could even be captured in a realistic attack scenario)
great talk, very interesting topic. was that Daft Punk? there is a market for signals in the frequency range above audible frequencies up to a few hundred kHz: bat detectors it is quite the pain to find sensors for said range and not many off the shelf DSPs can be used for this use case.
i remember him from the EFNET, #OlsenTwins til he got himself banned by court order :p That said he needs to get where he's going im like 20+ mins in and all i've gotten was a buncha nostalgia, physics 101, and hacking history lesson and thats great but we know all this already get to the point! So many people I knew worshiped this guy at the time, none of them were hackers becaue the hacker type people were doing all kinds of awesome stuff while not being stupid enough to _accidentally_ bring down an entire social media platform.
hi stozman777, just wanted to let you know that I read your comment aloud and everybody in the room stood up and clapped. you are a god to me, to all of us

That talk covered alot of ground really quickly.
He has a lot to share, and not much time.
When someone brag's about their first machine and it could run windows and mIrRC, emotional damage.
Feeling old yet?
fuck how old are you, like 100?

hay sam, if you see this, im glassblower in the LA area. would gladly help you out with any of your boro needs
Samy is the one you want on your team. Always pushing the envelope and setting new standards
Damn this is the best video I've seen about hacking

i too am fascinated by the piezo electric effect. i love that one need just understand resonance to start wielding this phenomena

From Phrack to fricken Laser Beams! When does a research lab become a mad science lair? :)
Holy shit I have never been talked down to so much in a "technical" talk
Seeing the new iPhone Lidar in IR is pretty cool 37:19

8:34 i’m eight minutes in, and I’m wondering if that guy fell into the magical meth cauldron as a child.. 😮
I just couldn't take it anymore. Watching someone trying so hard to be funny while rambling away. I had to stop.
nice presentation, great story telling but maybe because I have 20years more than the presenter I did not learn a new thing.
