kv4p HT – Turn an Android smartphone into a ham radio transceiver

kv4p HT is an open-source hardware VHF or UHF radio designed to plug into the USB-C port of an Android smartphone and turn it into a handheld ham radio transceiver. It’s based on an ESP32 wireless module and an SA818 radio module. This accessory makes your phone capable of off-grid voice and text communication with a Technician-class amateur radio license. It’s small enough to fit into a pocket, partially because it does not need a battery, relying on the built-in battery of your phone. kv4p HT V2.0 specifications: Wireless module – ESP32-WROOM-32E-N4 SoC – ESP32 dual-core Tensilica LX6 microcontroller @...

Mise en Abyme: London – Contemporary art through the lens of film noir

Last month, at The Black Shop in King’s Cross (London), this exhibition assembled conditions where images echoed, matter unsettled, and perception sliped.

Linux-based Vega OS replaces Android-based Fire OS in Amazon Fire TV Stick 4K Select

Amazon has recently introduced the Fire TV Stick 4K Select media streamer with a MediaTek MT8698 quad-core Cortex-A55 processor, 1GB RAM, 8GB eMMC flash, HDMI 2.1 video output, and WiFi 5 and Bluetooth 5.0 connectivity. However, the most interesting part of the announcement is the software, as Amazon has dropped the Android-based Fire OS used in its previous devices and instead relies on the new Linux-based Vega OS for the Fire TV Stick 4K Select. Amazon Fire TV Stick 4K Select (AFTCA002) specifications: SoC – MediaTek MT8698 MCM CPU – Quad-core Arm Cortex-A55 clocked up to 1.7 GHz GPU –...

Free Stuff - July 2025

The belated July 2025 recipient for the Great Scott Gadgets Free Stuff Program is Murat Sever, a professor from Turkey who teaches at TOBB ETU University and recently ran a workshop titled “Simple Replay Attack Demo with GNU Radio.” In this workshop, Murat utilized several open-source software and hardware tools to demonstrate how to receive and transmit RF signals. Workshop participants then used SDR and GNU Radio to perform replay attacks with the captured radio signals. We sent a handful of HackRF Ones to Murat for participants to learn and experiment with in this workshop. He has also informed us...

Носить электроны в решете, или зачем радиолампам дырявые аноды?

Радиолампы (они же — электронные лампы), несмотря на вопиющее моральное устаревание, до сих пор интересуют и интригуют, взять тот же пресловутый «ламповый звук». Интересны и их история, технология, конструирование, вплоть до самостоятельного любительского изготовления лабораторных образцов. Простой вопрос в этом смысле неожиданно увлёк в дебри электровакуумной технологии. Итак — зачем же некоторым приёмно-усилительным лампам (ПУЛ) сетчатые аноды — натурально, решето, тогда как этот электрод должен принимать поток электронов с катода и получше рассевать образовавшееся тепло?

VEF ТА-12. Оживляем раритетный телефон с АОН

Приветствую всех!
Пожалуй, этот девайс стал одним из самых запоминающихся артефактов проводной телефонии. Именно на базе этого телефона было создано немалое количество определителей номера на процессорах КР580ВМ80А и Z80.

Так уж получилось, что ко мне в руки попал такой АОН. Как насчёт посмотреть, как он устроен, и вернуть его к жизни? Именно этим мы сейчас и займёмся.
