Adafruit’s new MEMENTO – Bare Board Camera module is powered by the ESP32-S3 and can be programmed with CircuitPython or Arduino. The module includes a camera with an OV5640 sensor which features auto-focus capabilities and the board includes a 1.54″ 240×240 Color TFT to display the images. Previously we have covered many ESP32-based camera modules […]
Hitag transponders are employed in a wide range of car keys to prevent theft and unauthorized starting of vehicles. They are also a contributing factor to the increased cost of duplicating car keys for many models that incorporate this technology. Nevertheless, there is currently a software developer who collaborates with these transponder keys, all thanks

Arduino and Silicon Labs have joined hands to both bring Matter-compatible SiLabs wireless microcontrollers to the Arduino IDE and then design an upcoming Arduino Nano based on SiLabs MGM240 Arm Cortex-M33 microcontroller with Matter, Thread, Zigbee, and Bluetooth LE protocols. Available now: Arduino Core for Silicon Labs devices The first phase of the collaboration involves
Arduino and Silicon Labs collaborate to bring Matter to Arduino boards and IDE Continue Reading
An oscilloscope can be an expensive piece of equipment, but not every measurement needs four channels and gigahertz sampling rates. For plenty of home labs, old oscilloscopes with CRTs can be found on the used marketplace for a song that are still more than capable of getting the job done, but even these can be

DIY e-bikes are often easy to spot. If they’re not built out of something insane like an old washing machine motor, the more subtle kits that are generally used still stand out when compared to a non-assisted bike. The motors tend to be hub- or mid-drive systems with visible wires leading to a bulky battery,

As fun as claw games are, the jaws are always disappointingly weak, and you usually end up with bupkis. What if the jaws were completely within your control? That’s the idea behind [Upside Down Labs]’ muscle-controlled servo claw game. While electromyography (EMG) is great for identifying neuro-muscular abnormalities and allows for amazing prosthetic limbs to work,

Have you ever imagined commanding a device solely with hand motions? Envision your phone wirelessly sending emojis to friends representing your hand gestures in real-time. This vision is now a reality! Using ST’s innovative multi-zone Time-of-Flight sensors, camera-free gesture recognition is possible. AI algorithms running on the low-power STM32 microcontroller identify hand poses with minimal

DIY electric personal vehicles are a field where even hobbyists can meaningfully innovate, and that’s demonstrated by the Mega-Wheelie, a self-balancing one-wheeled skateboard constructed as an experiment in traversing off-road conditions. [John Dingley] and [Nick Thatcher] have been building and testing self-balancing electric vehicles since 2008, with a beach being a common testing ground. They suspected

Although we generally think of Internet of Things (IoT) and similar devices as things that are scattered around above ground, there are plenty of reasons to also have such devices underground. These so-called IoUT devices are extremely useful when it comes to monitoring underground structures, but communication via radiowaves is obviously impacted when soil is
