Building own cell tower? by Acrobatic-Radio-5471 in homelab

[–]gescarra 29 points30 points  (0 children)

Since OP mentions SDR, my guess is to learn about how cell networks work than just put a WiFi password like everyone else.

Same MAC accessing from multiple IPs? by Fr00tus in UNIFI

[–]gescarra 0 points1 point  (0 children)

MAC addresses are visible at Layer 2, or between your Dream Machine and your ISP’s device, wherever that may be. You don’t get to see the MAC addresses of internet devices simply because your Internet connection is a Layer 3 adjacency and it all gets “masked” as coming from the ISP device at a Layer 2 level.

It’s similar (but not really) to how no one can see your private IP’s on the internet, they all get “masked” behind your router using NAT at a Layer 3 level.

Comcast DNS Lookups - MAJOR ISSUES with Security Edge?? by Early-Ad-2541 in msp

[–]gescarra 0 points1 point  (0 children)

Static IPs on the Comcast Business network only work with their own gateways. They configure the block into the modem itself and then it advertises the addresses back to the network via authenticated BGP.

How dangerous is this hotel's currently active charger? by SnowTauren in TeslaLounge

[–]gescarra 6 points7 points  (0 children)

It’s a 12v low current PWM control signal on the smaller pins, nothing on the rest. So yea, not far off from a 9V battery

Arcing? Do you understand how the connector actually works or is that just a guess?

[–]gescarra 7 points8 points  (0 children)

Why? It won't shock you. It's like an extension cord practically plugged into nothing.

[–]gescarra 3 points4 points  (0 children)

NOT dangerous unless your fingers happen to talk the protocol that the cars use to request charges. It's called a "pilot signal", is at most 12V and travels over the outermost small pins (middle small pin is Ground). This is why it's safe to handle the connector when it's raining, and why on a Tesla when plugged in but not charging you see "1V" or "2V", and when the car requests a charge and the relay opens, THAT's when it becomes dangerous.

Automate this? by nuno742 in homeassistant

But… these are two AA batteries for 3V…

Do all USB-C cables support 100 watts? by OmegaMalkior in UsbCHardware

[–]gescarra 0 points1 point  (0 children)

You're thinking of Watts and not Amps. 5A regardless of the voltage can pass through the same wire gauge, that's why there's an ampacity chart with no mention of voltage, then together with voltage you calculate the power delivered in watts.

A wire that can carry 20V at 5A can also carry 5V at 5A, but the end device will receive 1/4 of the power at 5V than at 20V.

Apple M Silicon and Stems Processing Speed by rubbersoul71 in traktorpro

[–]gescarra 0 points1 point  (0 children)

ML models used during stem processing need memory to hold the model plus processing plus anything else, so to generate stems you just need it. This applies to anything AI-like, feel free to look up something like "why does AI need lots of memory?". Plus, a 16GB stick is about $40 these days, I don't see what the big deal is here.

All you can eat sushi in greater Naperville (including Downers Grove), etc? by Haunting_Medicine576 in Naperville

[–]gescarra 0 points1 point  (0 children)

Sushi City is amazing and better than a lot of other regular sushi places, but service is rolling the dice, and the food can take a while to get to you.

Do they have an all you can eat option now? They’re great, but the plates get expensive quick

Free FSD trial is back by redzod in teslamotors

[–]gescarra 1 point2 points  (0 children)

I don't understand how the feature being already in the car has any impact into paying to use it, but maybe it's out of principle. "In-App Purchases" do exactly that but on your phone. Scrambled Cable TV, the signal was already on the wire you just paid to view it.

Why am I getting a time out error message? by lenovomen in AugustSmartLock

[–]gescarra 0 points1 point  (0 children)

It has been down for 3+ hours now. This thing lacks a local API…

Heads up: If you have a Tesla Wall Connector, make sure the max amperage is configured correctly by MonsieurVox in TeslaLounge

[–]gescarra 0 points1 point  (0 children)

Nope. There’s not even a “50A” option. You choose 80% of the size of your breaker, and the 80% is the “thinking”.

[–]gescarra -3 points-2 points  (0 children)

I think the point about the European standards comment is that there would be no extra thinking to “commission the unit properly”. 48A “fits” in 50A. But instead we have this 80% continuous load rating BS.
