EnderSpark: Convert Your Broken Creality FDM Printer Into An EDM machine!

https://invidious.privacyredirect.com/watch?v=iLnna7q0drs

EDM (Electrical Discharge Machining) is one of those specialised manufacturing processes that are traditionally expensive and therefore somewhat underrepresented in the DIY and hacker scenes. It’s with great delight that we present EnderSpark, a solution to not one but two problems. The first problem is how to perform CNC operations on hard-to-machine materials such as hardened metals (without breaking the bank). The second problem is what to do with all those broken and forgotten previous-generation Creality Ender 3D printers we know you have stashed away.

To be honest, there isn’t much to a cheap 3D printer, and once you ditch the...

The Gemini 305 is a compact stereo 3D camera developed specifically for robotic wrist mounting. Measuring 42 […]

A New Kind of Inductively-damped Compass

https://invidious.privacyredirect.com/watch?v=eiDhbZ8-BZI

At some point during our primary school careers, most of us probably constructed a simple compass, often by floating a magnetized needle on a cork in a cup of water. The water in such a configuration not only lets the needle spin without friction, but also dampens out (so to speak) the needle’s tendency to swing back and forth across the north-south line. Liquid-filled compasses use the same principle, but even well-made compasses can develop bubbles when exposed to temperature or pressure variations. Rather than accept this unsightly state of affairs, [The Map Reading Company] designed a new kind of...

Radxa NX4 system-on-module runs RK3576 with LPDDR5 and 6 TOPS AI

Radxa has announced the NX4, a compact SoM designed for embedded, edge computing, and multimedia applications. The module is built around the Rockchip RK3576 or RK3576J processor and targets space-constrained designs that require a balance of CPU, GPU, and neural processing performance. The Radxa NX4 integrates an octa-core CPU configuration with four Arm Cortex-A72 cores […]

AMD Embedded+ mini-ITX Board features Ryzen AI Embedded P132 CPU, Versal AI Edge Gen2 VE3558 SoC FPGA

At CES 2026, Sapphire Technology introduced the EDGE+VPR-7P132, an “AMD Embedded+” Mini-ITX motherboard built around AMD’s newly announced Ryzen AI Embedded P100 series of SoCs, namely the hexa-core Ryzen P132 (V4526iX) CPU, and an AMD Versal AI Edge Gen 2 VE3558 SoC FPGA, which features octa-core Arm Cortex-A78AE + ten Cortex-R52 real-time cores beyond FPGA fabric. It’s the first AMD Ryzen AI Embedded motherboard we’ve seen. It represents a massive update from last year’s Edge+ VPR-5050 motherboard, which relied on Zen 2-based Ryzen Embedded V2000 series and first-generation Versal silicon. The new VPR-7P132 skips multiple generations, jumping straight to Zen...

XIAO ePaper DIY Kit – EE02 – An ESP32-S3 board designed for 13.3-inch Spectra 6 color E-Ink display

Seeed Studio’s XIAO ePaper DIY Kit EE02 is an ESP32-S3 WiFi and Bluetooth board designed specifically for the 13.3-inch Spectra 6 color E-Ink display provided by the company. It’s based on a similar design as the XIAO ePaper DIY Kit-EE04 (ESP32-S3) and XIAO ePaper DIY Kit-EN04 (nRF52480) introduced last December, which are suitable for smaller 1.54 to 7.15-inch ePaper displays. Like the previous models, the new EE02 model also includes a battery connector with a power switch, a built-in charging IC, and comes with one reset and three user buttons. With support for a larger 13.3-inch color ePaper display, it’s...

ASUS UGen300 USB AI Accelerator targets edge inference with Hailo-10H

ASUS has announced the UGen300 USB AI Accelerator, a compact external device designed to add hardware-accelerated machine learning and generative inference capabilities to existing systems over a USB connection. The UGen300 is built around the Hailo Hailo-10H processor, which ASUS rates at up to 40 TOPS (INT4) of inference performance. The accelerator integrates 8 GB […]

THIRDREALITY’s Linux Box Dev Edition is a compact smart home gateway aimed at developers, educators, and system integrators working with open-source automation platforms and standard smart home protocols. THIRDREALITY lists a quad-core processor, 2 GB of RAM, and 8 GB of onboard storage, along with integrated wireless connectivity including dual-band Wi-Fi (2.4 GHz and 5 […]

Home Assistant-compatible Makerfabs ESP32-S3-based energy meter features BL0942 energy metering IC

The Energy Meter for Home Assistant is an ESP32-S3-based single-phase energy monitoring and control module designed to work with Home Assistant via ESPHome. It measures real-time power and energy consumption and also has a remote on/off control. The device is built around the BL0942 calibration-free energy metering IC, which supports voltage, current, power, and energy measurements with less than 1% error. It operates directly from AC 100–240V, includes an onboard 15A relay for switching loads, and provides electrical isolation for safety. Connectivity is done through USB and Wi-Fi using ESPHome for easy firmware flashing, API encryption, and automatic discovery in...

Электровакуумный геттер, газовыделение, газопоглощение в ЭВП

Подобно тому как принципиальная схема отличается от прибора в натуре, отличается и радиолампа от иллюстрации в разделе «Термоэлектронная эмиссия» школьного учебника физики. Электронная лампа, шире — электровакуумный прибор (ЭВП), неизбежно обрастает технологическими и вспомогательными элементами, необязательными в демонстрационном случае, однако необходимыми для практических ламп. Например, таким элементом, позволяющим сильно удешевить производство среднестатистической приёмно-усилительной лампы и обеспечить её ресурс в сотни и тысячи часов, является геттер, иначе — газопоглотитель — микроминиатюрный высоковакуумный насос внутри лампы. Существует несколько типов геттеров и несколько десятков их видов. Попробуем взглянуть на них глазами самодельщика, заодно рассмотрим и газовыделение в вакуумных приборах — паразитные явления, неразрывно...
