Видаліть ви той ліфтоф і забудьте як страшний сон - RDS, TrypFPV, UFDC ось на чому потрібно навчати.
В TrypFPV є можливість додати ваги дрону. І ти її відчуваєш. По відгуками кадетів майже не відрізняється від сімки з бч на полігоні.
Після цього курсанти швидше адаптуються

Garmin a 📻 detekce dronů?
Je a bude potřeba velké množství detektorů, jak na 🇺🇦 pozice, tak i pro další bezpečnostní role v Evropě, jakými jsou ochrana osob, kritické infrastruktury, muničních skladů a dalších.
Máme POC detektoru, který vychází z architektury a fíčur ukrajinských detektorů Chuyka, Tsukorik atp., a který chceme později mít i na našich dronech 🧟♂️ Klekánice a 🧟♀️ Polednice, aby operátor věděl, že ho ohrožuje interceptor.
Krabička o velikosti RPi5, ale bez interní LiPo a bez displeje.
Detektor do batohu nebo na vestu, napájený přes 6S baterii — prostě dronařskou, kterých je hodně, a detektor vydrží dlouho běžet.
Zatím MVP a trocha kódu pro ověření, jestli má smysl použít Garminy pro náhled na měření a události.
Při detekci zavibrují (ehm, Garminy nic nedetekují, jen zobrazují). Když si dva povídají, tak dron můžou slyšet pozdě, ale vibrace do ruky cítí člověk hned.
Je na tom samozřejmě ještě dost práce jako je RF fingerprint (BW/duty/hop rate) protocol decode aaaatp.
Jak říkám, zatím MVP. Jeden kousek na testování jsme slíbili klukům v 🇨🇿 AČR a další je slíbený samozřejmě i klukům na 🇺🇦 Ukrajinu.
Jsme 🇨🇿 @AerorozvedkaCZ a budujeme schopnosti se bránit.

how to get started in FPGA
most people start wrong.
they buy a board
open vivado
and immediately get overwhelmed.
fpga is not programming.
it’s hardware design.
you are literally describing circuits.
start like this →
1. understand digital logic
learn:
• logic gates
• flip flops
• combinational vs sequential logic
• finite state machines
• timing
without this, nothing will make sense.
2. learn a hardware description language
pick one:
• verilog
• vhdl
verilog is simpler for beginners.
you are not writing software.
you are describing how hardware should be wired.
3. learn simulation first
before touching hardware.
tools:
• verilator
• modelsim
• iverilog
write simple modules and simulate them.
example progression:
• led blinker
• counter
• uart transmitter
• simple cpu
4. then buy a cheap fpga board
good starter boards:
• basys 3
• icebreaker fpga
• tang nano 9k
don’t start with expensive xilinx boards.
5. learn the full flow
hdl → synthesis → place & route → bitstream → hardware
this pipeline is the core skill.
6. study real designs
read open source projects:
• risc-v cores
• gpu experiments
• network accelerators
reverse engineer them.
7. combine fpga with software the real power appears when fpga works with:
• embedded cpu
• robotics
• signal processing
• high speed compute
fpga sits between software and silicon.
once you understand that layer,
you start thinking like a hardware architect.
