ESP-Scope is a web-based oscilloscope built using the ESP-IDF framework and Gemini 3 LLM

ESP-Scope is an open-source firmware transforming any ESP32 board into an oscilloscope using one of the ADC pins up to 83,333 Hz sample rate (on the ESP32-C6) and visualizing the results over Wi-Fi in a web browser, be it Google Chrome, Mozilla Firefox, or others. It’s not the first ESP32 oscilloscope project we’ve seen, as last year, we covered Bojan Jurca’s “Esp32_oscilloscope” Arduino sketch doing something very similar. The ESP-Scope is a little different, since it’s based on the ESP-IDF framework, and was used to test AI code generators, specifically “Google Antigravity using Gemini 3, with refinements, hints and tips and overall design specified by a human”. It just took a few hours to build. ESP-Score firmware features: Real-time signal visualization on a web browser. Adjustable sample rate (1-83333 Hz) and attenuation. Crosshair functionality for precise measurements Adjustable trigger level Test signal generation Reset functionality to clear settings and reload […]

ExtrudeX machine recycles failed/old 3D prints into new filament (Crowdfunding)

ExtrudeX machine recycle 3d printer filament

When 3D printing, users will always waste filament one way or the other, either due to a failed print or because of the support for the print, and there may also be test/old prints that you don’t need/use anymore, for example, a retraction cube or a benchy. That means all that material usually ends up in the dustbin. Priyank Pal, founder of Creative3dp, did not like all that waste, so he created the ExtrudeX machine to recycle 3D print waste and filament scraps back into usable filament. On top of that, the machine itself is 3D printable and much more affordable than commercial solutions from companies such as Filabot. I’d usually provide the specifications here, but as a crowdfunded project, the ExtrudeX’s full technical details are not fully available. We just know that a single DC gear motor drives the main screw inside a metal barrel, while band heaters and […]

Creality Sermoon S1 3D scanner review – Part 2: Using Creality Scan 4 software with Intel Graphics

Creality Scan 4 Sermoon S1 3D scanner review

Earlier this month, we checked the specifications and did an unboxing of the Sermoon S1 high-end 3D scanner with support for blue laser and infrared scanning. I had some concerns about my host machines due to the fairly high minimum requirements: Intel Core i7 Gen7 CPU, NVIDIA GPU (6GB VRAM), 16GB RAM, Windows 10/11 (64-bit). I had planned to use an ASUS Vivobook 16 laptop with a 13th Gen Intel Core i5-13500H SoC with a 12-core Raptor Lake processor and integrated Intel Iris Xe Graphics, as well as 16GB of RAM to run Creality Scan 4 software. After talking with Creality, it was confirmed to me that a “dedicated graphics card” was required. I have some good and bad news. The good news is that I might get a mini PC with an NVIDIA RTX 5060 Ti (16GB) external GPU for review. The bad news is that I have to […]

Arduino-programmable environmental and air quality sensor kit features ENS160 and BME280 sensors

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display Module. It provides VOCs, eCO₂, temperature, humidity, and barometric pressure data in real time, making it ideal for Smart Home experiments, classroom projects, or hobby weather-station builds. The kit integrates a Sciosense ENS160 air-quality sensor and Bosch BME280 environmental sensor connected via Qwiic, which measures TVOCs, eCO₂, temperature, humidity, and pressure with an on-device AQI indicator. It includes the Novaduino display PCBA, 2.4-inch IPS touchscreen, buttons, rotary encoder, Feather M0 Express or RP2040 module support, headers, mechanical hardware, and optional 3D-printable enclosures (STL/F3D/STP). Designed for learning soldering, assembly, and Arduino programming, the kit is uncalibrated and intended for educational and experimental use only. Novaduino Environmental Sensor Kit specifications: Core Platform – Novaduino 2.4-Inch Display Module Supported development boards – Adafruit Feather and […]

Black Friday and Cyber Monday 2025 – International deals, coupons, and events

Like every year since 2014, I’ll list a few international deals for Black Friday and Cyber Monday 2025, as many CNX Software readers cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events, which will take place from November 20 to December 1. I’ve gathered various deals, discount coupon codes, and events from relevant manufacturers of single board computers, MCU development boards, mini PCs, Smart Home devices, and DIY products, as well as popular online stores, including AliExpress, Banggood, and others. AliExpress Black Friday and Cyber Monday 2025 event AliExpress sales event for Black Friday and Cyber Monday 2025 has just started and will last until December 3, 2025 (although I can see until November 29 and December 4 in some places). You can use some of the coupons on the screenshot above, or some alternative coupon codes for the US and some other countries (excluding DE, RU, […]

Kode Dot – An easy-to-use, pocket-sized, battery-powered ESP32-S3 devkit (Crowdfunding)

Kode Dot is a pocket-sized ESP32-S3 maker device for prototyping with a built-in 2.13-inch AMOLED, a 500mAh battery, a 9-axis IMU, a microphone and a speaker, an RTC, a few buttons, a GPIO header, and a magnetic connector for expansion. Kode Dot is designed to simplify the prototyping process. Users can still write code using the Arduino IDE, PlatformIO, or ESP-IDF framework and upload it via the kit’s USB-C port, but thanks to kodeOS firmware, each program becomes a standalone app with its own name, icon, and interface, accessible from the graphical user interface. Kode Dot specifications: SoC – Espressif Systems ESP32-S3 dual-core microcontroller with 2.4 GHz Wi-Fi, Bluetooth 5 LE, ESP-NOW peer-to-peer protocol System Memory – 8 MB octal PSRAM Storage 32 MB octal SPI flash microSD card slot Display – 2.13-inch Color AMOLED with 502 x 410 resolution Audio ICS-43434 MEMS microphone 1W MAX98357A speaker amp USB – […]

Creality Sermoon S1 high-end 3D scanner review – Part 1: specifications and unboxing

Creality has sent me the Sermoon S1 high-end 3D scanner for review. It supports blue laser line and infrared structured light scanning, offers high accuracy up to 0.02mm, scans objects from 5 x 5 x 5 m3 to 4000 x 4000 x 4000 mm3, and looks like a pretty cool device overall. I’ll start the review by diving into the specifications, before going through an unboxing to check out the 3D scanner and its accessories. I’ll then need to study a bit more before testing out with different objects in the second part of the review. Sermoon S1 3D scanner specifications Scanning Modes Blue laser lines Single Blue Laser Line Scanning rate: 108,000 measurements/s Working distance – 200 to 600mm Outdoor Scanning – Below 100,000 lux Laser Safety – Class II (eye safe) 7 Parallel Blue Laser Lines Scanning rate: 756,000 measurements/s Working distance – 150 to 400mm Outdoor Scanning […]
