this is the exact one I have

retevis, it's just a rebrand

but I like it

I also have one of those radio dongles, the SDR-RTL things

really autistic though, only Tervy could understand it

I fucking love this community

yeah if you go on /k/ there's a /k/ommunications thread occasionally

they have good infographics and such

SDR-RTL <3

shit is nice specialy if half of the town uses shitty old zigbee and such communications on their "home automation"

:D

yeah the amount of plug ins and things you can do is pretty insane

>ability to control schools internal coms and lights and heating via laptop

yes please

noticed that once when i was sitting on some newer classrooms

and they had all kinds of stuff

control school comms

lmao this is what I should've known when I was in school, the pranks would be insne

its only the per-room audio as far as i know (Also the LAB phones to control room)

i bet there is hole for me to tunnel tru for schoolwide messaging system too

but thats something i dont dare to do

well dare* but wont do if its not important (lets say someone starts shooting up at school)

first thing i was teached about breaking into stuff is that only use it when its needed (or really damn fun)

fun is always needed

really damn fun = settings 200 person lecture hall to 15*C

and after that switching it to +28

brand new systems all wired to control box

but control box has wireless remote

dun dun duuun

i also know that my neighbors have wireless stuff

but rather not mess with them

as i dont know "what" it is

wifi sprinklers

inb4 someones thermal planket shortcircuits cause of me

:D

also holy shit @Windatica i just checked the pdf you have updated it quite bit

niiice

that was a month ago

tervy is bit slow

dont bully

yeah never noticed it until now when i needed it
