Autonomous Submarine Relies On Color Detection

https://invidious.privacyredirect.com/watch?v=_M3SRvy68w8

We talk about all kinds of autonomous vehicles here at Hackaday, from aerial drones to rugged rovers. A little less common are the submarine builds, likely due to their technical complexity. That said, though they perhaps benefit most from autonomy given they’re so hard to talk to while underwater. In any case, [Ayman] has built an impressive sub that uses some rudimentary techniques to navigate around while under the surface. 

The build uses typical construction techniques for DIY subs of this size, with a clear acrylic tube serving as the body of the craft. It’s carefully sealed to ensure water ingress...

Дооснащение любительской электровакуумной мастерской. Вакуумметр, течеискатель, полярископ

Увы, электровакуумное дело, даже в его несложной любительской ипостаси, требует изрядного оснащения — приборы, материалы, инструменты, оборудование. К счастью, часть этого добра вполне возможно изготовить своими руками, если и не полностью заменив заводские аналоги, то, по крайней мере, получив инструменты более чем пригодные для домашних экспериментов. Здесь речь пойдёт о полярископе — несложном оптическом приборе, позволяющем увидеть и оценить внутренние напряжения в стекле и прозрачных материалах; простом приборчике для поиска течей в будущей вакуумной системе откачного поста [1]; вакуумметре до 10-3 мм рт. ст. на термопарной лампе-преобразователе ПМТ-2. Посмотрим, что и какими средствами удалось сделать, зачем эти приборы нужны и как работают.

reComputer RK3576/RK3588 Edge AI computers are supported by reComputer AI Lab one-click deployment platform

Seeed Studio has just launched the reComputer RK3576/RK3588 Edge AI computers designed for developers, embedded AI innovators, robotics, industrial AI, vision AI, local LLMs, and real-world edge deployment. Rockchip RK3576 and RK3588 computers are pretty common these days, and the Seeed Studio models offer triple video output, dual Ethernet (GbE or 2.5GbE), several USB ports, and M.2 expansion. But the most interesting part is probably the software with Armbian-based Linux OS and support for the reComputer AI Lab platform that enables one-click deployment of AI-accelerated computer vision, audio, and LLM/LVM demos. reComputer RK3576/RK3588 specifications: SoC (one or the other) Rockchip...

MeshToad V3 turns Linux systems into Meshtastic nodes

The NULLHOP MeshToad V3 is a Meshtastic-compatible LoRa radio module for Linux systems that allows computers to operate as Meshtastic nodes using meshtasticd. The device connects over USB and supports platforms ranging from Raspberry Pi boards to mini PCs and other Linux hosts. The radio subsystem is based on the EBYTE E22P-915M30S module integrating the […]

Flipper One – A Rockchip RK3576-powered portable Arm Linux computer and networking multi-tool

Flipper Devices has officially introduced the Flipper One open-source hardware portable Arm Linux platform and networking and Edge AI multi-tool powered by a Rockchip RK3576 octa-core Arm Cortex-A72/A53 SoC, and featuring a Raspberry Pi RP2350 for low-level control. You may think of it as a successor to the popular STM32-based Flipper Zero hardware and wireless hacking tool, but the company stresses that the Flipper One is NOT a replacement for the Flipper Zero. It is a different product with mainline Linux kernel support, no binary blobs (probably not 100% true), and open-source drivers, and operating at a different level of...

Procolored X one – A 3-in-1 laser engraver with UV and UV-DTF color printing (Crowdfunding)

Procolored X one is a 3-in-1 machine which combines a UV color printer, a dual-laser engraver (20W diode + 2W IR), and a UV-DTF sticker maker into a single, compact, enclosed unit. It is designed to simplify workflows for small businesses and DIY makers by bringing multiple functions into a single system. Traditionally, creating full-color engraved products requires multiple machines and a messy pre-coating step before printing. The X one simplifies this by using a special X-axis dual-track design that lets you switch between laser cutting and UV printing without moving the object, making the workflow faster and easier. Procolored X one specifications...

Coralboard features Synaptics Astra SL2619 Edge AI SoC, supports Google Gemma 3 inference

Synaptics Coralboard is a development board powered by a Synaptics Astra SL2619 Edge AI SoC with a 1 TOPS Synaptics Torq inference engine implementing a Google Coral NPU, and supporting hardware-accelerated Google Gemma 3 lightweight models. The board features 2GB of RAM and offers MIPI camera and display interfaces, a microSD card slot, a USB Type-A port, microphone inputs (I2S), mikroBUS and Qwiic- expansion connectors, and optional Wi-Fi and Bluetooth connectivity through an M.2 expansion slot. Synaptics Coralboard specifications: System-on-module – Grinn AstraSOM-261x SoC – Synaptics Astra SL2619 SoC with 2x Cortex-A55 cores @ 2GHz, 1x Cortex-M52 core @ 200MHz, and...

Hacknect – A wireless hacking USB cable with a built-in microSD card slot (Crowdfunding)

Little Gadgets’ Hacknect is an ESP32-S3-powered wireless USB Type-A hacking cable with Wi-Fi control, HID automation for keyboard/mouse events, payload deployment, and a microSD card slot hidden in one of the Type-A connectors. The USB cable is designed for makers, developers, automation enthusiasts, and cybersecurity researchers and can be wirelessly controlled from your smartphone or computer. It just looks like a normal cable, so any free USB cable that comes your way may look suspicious in the future. Hacknect specifications: Wireless SoC – ESP32‑S3 with WiFi 4 and Bluetooth 5.x Storage – MicroSD card slot (inside one of the USB...

ODROID-H5 – A $250 Intel Core i3-N300 SBC with 10GbE networking, four M.2 PCIe slots

Hardkernel ODROID-H5 is an affordable Intel Core i3-N300 octa-core Alder Lake-N SBC providing a 10GbE RJ45 networking jack, and four M.2 PCIe slots for storage, wired/wireless networking, or AI accelerator expansion. It relies on the same SoC as in the earlier ODROID-H4 Ultra SBC, but trades a single PCIe Gen3 x4 M.2 slot and four SATA ports for four M.2 slots, and upgrades from dual 2.5GbE  to single 10GbE. It still features four USB ports, but only one USB 3.0 port, and three USB 2.0 ports. ODROID-H5 specifications: SoC-  Intel Core i3-N300 CPU – Octa-core “Alder Lake-N” processor @ up...
