A Vulnerable Simulator for Drone Penetration Testing

https://invidious.privacyredirect.com/watch?v=EHTQv6IfnwI

The old saying that the best way to learn is by doing holds as true for penetration testing as for anything else, which is why intentionally vulnerable systems like the Damn Vulnerable Web Application are so useful. Until now, however, there hasn’t been a practice system for penetration testing with drones.

The Damn Vulnerable Drone (DVD, a slightly confusing acronym) simulates a drone which flies in a virtual environment under the command of of an Ardupilot flight controller. A companion computer on the drone gives directions to the flight controller and communicates with a simulated ground station over its own WiFi...

Любительские французские радиолампы 1920-х годов. Часть 2. Стеклодувное, ртутно-капельный вакуумный насос

Продолжим наше путешествие по волнам памяти — окунёмся в самобытную работу яркого представителя заграничных радиолюбителей начала прошлого века, с их примитивным оснащением, самодельными радиоэлементами и безмерным энтузиазмом. Франция, 1900-е годы, М. Н. Минье — скромный любитель, изготовлявший вакуумные триоды для своего радио самыми простыми, буквально подножными средствами и материалами (Часть 1). Радиолампы, как и любые электровакуумные приборы (ЭВП), кроме прочего, подлежат и непременной откачке, операции сложной и дорогостоящей (оборудование). Чем же обходились отважные пионеры ламповой эпохи, какими самодельными приборами, как изловчались их конструировать своими невеликими возможностями?

Накопитель цифровой информации. Самый загадочный прибор на базе МК-85

Приветствую всех!
Помните тот самый шифровальный калькулятор МК-85С? Так вот, девайсов специального назначения на базе этого микрокомпьютера было намного больше, чем можно было подумать.

Так получилось, что ко мне в руки попал, пожалуй, самый редкий и самый малоизвестный экземпляр из них. Что внутри этого чемодана и как он вообще работает? Давайте разбираться...

MR Browser is the Package Manager Classic Macs Never Had

Homebrew bills itself as the package manager MacOS never had (conveniently ignoring MacPorts) but they leave the PPC crowd criminally under-served, to say nothing of the 68k gang. Enter [that-ben] with MR Browser, a simple utility to fetch software from Macintosh Repository for computers too old to hit up the website.

If you’re not familiar with Macintosh Repository, it is what it says on the tin: a repository of vintage Macintosh software, like Macintosh Garden but apparently less accessible to vintage machines.

MRBrowser sys6 runs nicely on the Macintosh Plus, as you can see.

There are two versions available, depending on the age...

$14 development board features GUITION ESP32-P4 + ESP32-C6 module

While searching Aliexpress for new products, I found out about the JC-ESP32P4-M3-DEV from the Maker Go AliExpress store, another ESP32-P4 development board with features very similar to the  ESP32-P4-Function-EV-Board or the Wireless Tag WT99P4C5-S1 board, but built around the GUITION JC-ESP32P4-M3-C6 module, which combines ESP32-P4 and ESP32-C6 into a single package instead of having separate chips or modules on most other designs. Features include 32MB of PSRAM and 16MB of flash on the GUITION module, a microSD card slot for storage, a built-in microphone, speaker output via the ES8311 audio codec, and an audio amplifier. The board also offers a...

Improve Your KiCad Productivity With These Considered Shortcut Keys

https://invidious.privacyredirect.com/watch?v=T-voZId8eyw

[Pat Deegan] from Psychogenic Technologies shows us two KiCad tips to save a million clicks, and he made a video to support it, embedded below.

In the same way that it makes sense for you to learn to touch type if you’re going to be using a computer a lot, it makes sense for you to put some thought and effort into your KiCad keyboard shortcuts keys, too.

In this video [Pat] introduces the keymap that he has come up with for the KiCad programs (schematic capture and PCB layout) and explains the rules of thumb that he used to generate his...

Rockchip unveils RK3668 10-core Arm Cortex-A730/Cortex-A530 SoC with 16 TOPS NPU, RK182X LLM/VLM co-processor

The Rockchip Developer Conference 2025 (RKDC!2025) is now taking place in Fuzhou, China, with some interesting announcements such as the Rockchip RK3668 10-core Arm Cortex-A730/A530 processor with a 16 TOPS NPU and the RK182X RISC-V co-processor with support for up to 7B parameters LLM (large Language Model)or VLM (Vision Language Model). Rochchip RK3668 10-core Armv9 SoC Let’s have a look at the Rockchip RK3668 SoC, which looks quite similar to the RK3688 SoC unveiled last year, but with some differences. Preliminary Rockchip RK3668 specifications: CPU – 4x Cortex-A730 + 6x Cortex-A530 Armv9.3 cores delivering around 200K DMIPS; note: neither core...

8-Core ARM Pocket Computer Runs NixOS

https://invidious.privacyredirect.com/watch?v=yxfDNqZ9WTM

What has 8 ARM cores, 8 GB of RAM, fits in a pocket, and runs NixOS? It’s no pi-clone SBC, but [MWLabs]’s smartphone– a OnePlus 6, to be precise.

The video embedded below, and the git link above, are [MWLabs]’s walk-through for loading the mobile version of Nix onto the cell phone, turning it into a tiny-screened Linux computer. He’s using the same flake on the phone as on his desktop, which means he gets all the same applications set up in the same way– talk about convergence. That’s an advantage to Nix in this application, compared to the usual Alpine-based...
