Raspberry Pi Camera Module 3 review – HDR, autofocus, wide angle, and NoIR camera

A few days before launching the Raspberry Pi Camera Module 3 with HDR and autofocus, Raspberry Pi Trading asked me whether I would be interested in reviewing the new modules, and sent me three samples: the standard module, the Raspberry Pi Camera Module 3 Wide, as well as the NoIR version that lacks an IR filter and is better suited for night shots. It took a full week for DHL to send the package to my house, but I’ve now had time to review the new Raspberry Pi Camera Module 3, mostly with libcamera, but also Picamera2, focusing on the new features such as HDR, autofocus, and wide angle. I also had a quick try at the Raspberry Pi Camera Module 3 NoIR but without IR lights. Regular readers know I had already made some DIY camera mounts using empty gum bottles, and I just replaced the Lotte XYLITOL stickers […]

Quiet, ultrathin AirJet solid state active cooling chips could replace fans

Frore Systems Airjet Mini and Airjet Pro are active cooling chips that are just 2.8mm thick and quietly suck cool air in from the top of the chip before pushing it out the sides with the aim to replace traditional fan-based solutions in ultrabooks, or be integrated into VR headsets and smartphones for improved cooling. Yesterday we saw that cameras could clean themselves with micro-vibrations, and it happens that processors can be cooled with vibrations too as the Airjet chips are comprised of tiny membranes that vibrate at ultrasonic frequencies to generate a flow of air that enters through inlet vents in the top and transformed into high-velocity pulsating jets exiting from one side of the chip. The AirJet module is actually not placed directly on the processor in ultrabooks but on copper pipes because it allows for thinner designs that way. The company says the AirJet Mini and Pro […]

Teledyne e2v releases Hydra3+ high-resolution ToF sensor with 832 x 600 resolution

Teledyne e2v Hydra3D+ is a high-resolution Time-of-Flight (ToF) CMOS image sensor with 832 x 600 resolution, designed for real-time 3D detection and measurement without motion artifacts. The first ToF sensor I used was an STMicro VL53L0X ranging sensor that could measure distances accurately and quickly up to 2 meters away, then the company started to launch multi-zone ToF ranging sensors such as the VL53 that enabled new features such as touch-to-focus, multiple-target identification, flash dimming, or video tracking assistance, and one variant used for human detection. But the 832×600 resolution of Hyrdra3D+ brings even more interesting use cases with the ability to create 3D maps in real time. Hydra3D+ ToF sensor specifications: Sensor Resolution – 832 x 600 pixels Aspect Ratio – 4 : 3 Size type – 2/3″ (10.3 mm diagonal) Pixel type/size – square – Three-tap global shutter – gated global shutter / 10 μm Maximum frame rate […]

TI unveils ULC1001 ultrasonic lens cleaning chip for self-cleaning cameras

Texas Instruments (TI) has introduced the ULC1001 digital signal processor (DSP) ultrasonic lens cleaning (ULC) technology designed – when combined with DRV2901 piezo transducer driver – for self-cleaning camera systems to quickly detect and remove dirt, ice, and water using microscopic vibrations. Cameras used in the automotive, industrial, robotics, and smart farming industries may require cleaning from time to time and that usually means manual cleaning leading to potential downtime, higher maintenance cost, and so on. It could also be done through mechanical parts but that adds further complexity to the system, so instead, Texas Instruments ULC1001 and DRV2901 combo enables cameras to rapidly self-clear contaminants using vibrations to eliminate debris. The datasheet describes the ULC1001 as a “Configurable Ultrasonic PWM Modulator With I/V Sense Amplifiers” with the following specifications: Integrated Programmable Cleaning Modes Water (expelling) Deice (melting and expelling) Mud (dehydrating and expelling) Auto-Cleaning (detecting and expelling) Custom Cleaning […]
