Rikomagic DS08 – A Rockchip RK3588-powered 8K digital signage player with RTC and watchdog support

Rikomagic DS08 is a Rockchip RK3588-powered Android 13 digital signage player with 8K and 4K HDMI video outputs, RTC and watchdog support, and support for portrait and landscape orientation. It looks to be an update to the Rockchip RK3288-powered Rikikomagic DS02 introduced in 2020. The new model appears to have the same enclosure, but with a slightly different port layout, and much better specifications. Besides an octa-core Cortex-A76/A55 SoC, the system ships with 8GB of RAM and a 128GB eMMC flash, and features a Gigabit Ethernet port, WiFi 6 and Bluetooth 5.2 connectivity, optional 4G LTE, and a few USB...

Кустарные вакуумные триоды Клода Пайяра. Часть 4. Вакуумные насосы

Мы уже познакомились с Клодом Пайяром — французским радиолюбителем, в бытность, редактором журнала Radio-REF, энтузиастом-электровакуумщиком, воссоздавшим в своей мастерской кустарное производство практических триодов ТМ [1] (первых, 1920-х годов, промышленных «жёстких» — с высоким вакуумом, электронных ламп), и рассмотрели его самодельное огневое оснащение (Часть 1), установку для контактной сварки и технологическую печь (Часть 2), ламповую установку ТВЧ для дегазации электродов ламп при откачке (Часть 3). Сегодня мы взглянем на высоковакуумную установку Клода, самодельную, как и всё его оборудование.

Первые отечественные электронные лифты. УПЛ-10

Приветствую всех!

Давным-давно, ещё в советскую эпоху, большинство лифтов были релейными. Но уже в восьмидесятые начали появляться электронные станции. Конечно, до современных микропроцессорных систем им было очень и очень далеко, а построены они были на дискретной логике. Тем интереснее взглянуть на устройство таких блоков.

Так получилось, что ко мне в руки попала одна из таких станций управления. Так что сейчас у нас есть возможность посмотреть, как она устроена, и попробовать разобраться, как она работает. Традиционно будет много интересного.

The RAM Shortage Comes for Us All

The RAM Shortage Comes for Us All

Memory price inflation comes for us all, and if you're not affected yet, just wait.

I was building a new PC last month using some parts I had bought earlier this year. The 64 Gigabyte T-Create DDR5 memory kit I used cost $209 then. Today? The same kit costs $650!

Mini review of JOYROOM PODIX 140W 5-port USB GaN charger with power meter function

I’ve just received a review sample of the JOYROOM PODIX 140W 5-port USB GaN charger, which I found interesting because it integrates a power meter function for the whole charger and for each individual port, which could be useful for reviews of USB-powered boards and devices. In this short review, I’ll go through an unboxing, before testing the features with a smartphone, and trying to stress it a little with five devices, including a laptop, a USB-C powered HDMI display, a wireless display, an Android smartphone, and a Raspberry Pi 5 SBC. JOYROOM PODIX 140W charger unboxing I received the...
