How to use Tiny Open Loop Actuators for a Living Mirror

https://invidious.privacyredirect.com/watch?v=KHulZtR2Qkg

How do you go about making a mirror with 128 segments, each of which can be independently angled? That was the question that a certain bloke over at [Time Sink Studio] found himself pondering on, to ultimately settle on a whole batch of mini-actuators bought through AliExpress. These stepper-based actuators appear to be akin to those used with certain Oppo smartphones with pop-up camera, costing less than half a dollar for a very compact and quite fast actuator.

The basic design is very much akin to a macro version of a micromirror device, as used in e.g. DLP projectors, which rely...

Flux and Solder Paste Dispenser Looks Good While Doing It

Syringes are pretty ergonomic, but when manually dispensing flux and solder paste it doesn’t take long before one wants a better way. [Elektroarzt]’s flux and solder paste dispenser design uses 3D-printed parts and minimal hardware (mostly M3x20 screws, and an optional spring) to improve handling and control.

How does it work? The ratcheting lever mechanism is similar to that of a hot glue gun, where an arm slips into notches in a rod when pressed down, driving it forward and never backward. In the process,...

EnviroGo ESP32-S3 wearable environmental monitor features 7 sensors (Crowdfunding)

EnviroGo is an ESP32-S3-based wearable environmental monitor that tracks Organic Compounds (VOCs), UV index, temperature, humidity, air pressure, light, and motion via a 9-axis MEMS sensor. It is designed for indoor and outdoor use, and can be worn, clipped to a bag, or magnetically mounted, making it suitable for homes, offices, travel, labs, and daily use where real-time environmental data is needed. EnviroGo supports built-in Wi-Fi and Bluetooth connectivity through the ESP32-S3 WiSoC, features a small 0.96-inch IPS display, a microSD card slot for local data logging, and an RTC for time-stamped records. The device samples data at configurable intervals,...

More than 50 […]

2-channel GMSL camera adapter board supports Raspberry Pi 5 and NVIDIA Jetson Orin Nano/NX

After phasing out the earlier MAX9296-GMSL-Camera-Board, Waveshare has now released the MAX9296-GMSL-DESER-MODULE 2-channel GMSL camera adapter board designed for high-speed, low-latency video transmission on the Raspberry Pi 5 and NVIDIA Jetson Orin Nano/NX developer kits. The adapter is built around the MAX9296A deserializer, and supports two MATE-AX FAKRA Z coaxial inputs for long-distance video transmission and two 22-pin CSI outputs for connection to the host. It supports both GMSL1 and GMSL2 cameras (such as the Sony ISX031) via software configuration and is compatible with serializers like the MAX9295, MAX96717, and MAX96705. These features make it suitable for applications such as...

Witty Pi 5 HAT+ – A Raspberry Pi RP2350-based power scheduler with time, temperature, and voltage-based triggers

Designed by UUGear, the Witty Pi 5 HAT+ is a power scheduler board for Raspberry Pi that features an RP2350 MCU for running scheduling logic. It includes a high-precision RTC with voltage and temperature monitoring for automated power on/off, making it suitable for solar-powered projects, environmental monitors, and industrial controllers that require scheduled power on/off control to extend battery life. The board follows the Raspberry Pi HAT+ specification and accepts power from either a 6V–30V DC input through a terminal block or a 5V USB-C supply, while delivering up to 5A to the Raspberry Pi and connected peripherals. It can...
