Flipper Zero Must Have Modules By sn0ren “Flipper Zero is a pocketable electronic multitool. It can read and emulate RFID and NFC tags. It can copy wireless remote control signals. It can send infrared commands. And the GPIO ports can be used for electronic projects or to expand the functionality of Flipper Zero to completely new levels. All while being a cute little tamagotchi-like dolphin. This video is sponsored by Lab401 who've sent me most of the modules featured. Lab401 is a web-store based in europe, specialising in pen-testing hardware and also carrying Flipper Zero.“ #flipperzero #fz #hackrf #rf #rfid #nfc #gpio #module #sn0ren #ir #infrared #vhf #uhf #hf

This device makes Meshtastic the BEST off-grid tech By Level 2 Jeff “Meshtastic is great! But it needs 'halo' devices like the T-Deck to expand beyond hobbyists.” #mesh #meshtastic #tdeck #offgrid #emcomms

The Mesh Radio Rabbit Hole: 🐇🕳️ aka The Meshtastic to Reticulum Pipeline This is something to be very excited about. People will get thier first introduction to mesh radio via Meshtastic, as the networks grow, and their skills and understanding increase, they can upgrade their existing equipment to reticulum RNode. #mesh #meshtastic #lora #reticulum #rnode #rns #sideband #nomadnet View quoted note →

The Meshtastic Fruit Machine!!! By Andy Kirby ***The title of this video is kinda deceptive but the it introduces an interesting way to use mesh radios. “Time for a bit of lighthearted fun on the Mesh, the Meshtastic fruit machine is a simple html page that gets message data from multiple nodes using the Liam Cottle map. It's a great way of having some fun with other mesh users but also it gives you feedback on where your messages are reaching!” ⚡️⚡️⚡️Think about how you could use this information and put it to some other use case with this technology.⚡️⚡️⚡️ Final thought: If someone were to make a sportsbook over local mesh network, that would be a very interesting. #meshtastic #mesh #lora #casino #casine #slot #fruitmachine

DYK? Cellphones are basically networked radios. Currently, there are two major standards in use around the world: CDMA vs. GSM: What’s the Difference? CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications) are two popular mobile network technologies: 1. Technology Approach: • CDMA assigns a unique code to each call, allowing multiple users on the same channel. • GSM uses time slots (TDMA) and frequencies (FDMA) to separate users. 2. SIM Cards: • CDMA phones traditionally didn’t use SIMs (device-specific). • GSM phones always use SIM cards, making it easy to switch devices. 3. Global Reach: • GSM is widely adopted worldwide, ideal for global roaming. • CDMA is more regional, mainly used in the US and parts of Asia. 4. Data & Speed: • CDMA often provided faster data rates in 3G. • GSM became more versatile with 4G LTE, leveling the playing field. In today’s world, 4G LTE and 5G have mostly unified these differences, with most carriers supporting SIM-based LTE systems. #TechTalk #MobileNetwork #CDMAvsGSM #cellphones #lte #gsm #cdma

Ham Radio Basics: Different Frequencies Propagate Differently The Best Radio Frequency For Local Communications By Radio Prepper “While I would be tempted to say "it depends," I will in this video pick what I believe is the best band for me or for prepping. It isn't any of the usual suspects! Note that you will need an amateur radio license to use it. It's very easy to get, go for it!” ⚡️ ⚡️ ⚡️ “The Best” is subjective, but understanding these principles for your specific communications needs is the important issue. Furthermore, “good enough” is frequently as good as having “the best” if your communication is successful. ⚡️ ⚡️ ⚡️ #ham #hamradio #radio #amateurradio #hf #mf #uhf #vhf #6m #2m #40m #20m #10m
