Osram Opto Semiconductors presents the SFH 5701 A01, a new ambient light sensor (ALS) with integrated circuitry (IC). The SFH 5701 A01 ambient light sensor is Osram Opto Semiconductors’ latest addition to its portfolio for the automotive sector and the company’s first IC-based component for which a separate power supply pin is not required. The ambient light sensor (ALS) […]

I have done several pen and laser machines lately, so I decided to create a custom PCB for Grbl_ESP32 for these types of machines. This is a small (70mm x 60mm) PCB with all the features a pen plotter or laser cutter/engraver would need. These typically use stepper motors for the X and Y axes.

Osram Opto Semiconductors is launching a new product family with Bidos PLPVQ 940A, its first Vertical Cavity Surface Emitting Laser (VCSEL) for new areas of application such as 3D sensing and facial recognition for mobiles. [via] This announcement comes shortly after the acquisition of US specialist Vixar. The VCSEL acts as a light source, illuminating the

A group of researchers led by Nick Vamivakas from the University of Rochester has successfully produced particles which have negative mass in an atomically thin semiconductor material. According to the researchers, they have created a device that can generate LASER light using a significantly small amount of energy. All made possible with the help of this so-called negative mass particles. Quantum physicist Nick
I finished this laser wall trigger for my HIGH RESOLUTION AND ACCURACY CHRONOGRAPH. The purpose of this device is to generate the trigger start and stop impulses for my chronograph as soon as an object disrupts any of the laser beams. So if I have two laser walls (with one or more laser beams on

Plugging the laser module on Arduino Isn’t easy to plug a module when you have no datasheet or some wiring schemes, the chances are that you’ll probably burn it if you provide a current greater than the supported. The module I have was bought on the DX.com and it came with 3 pins, “-” mark,

Audi is fitting laser headlights as standard on its limited-edition Audi R8 LMX. Lasers are away of adding intensity to the centre of a headlight main beam, allowing solid-state front lighting to beat ‘xenon’ HID (high-intensity discharge)-based lamps which were continuing to out-shine LED headlamps. In a laser headlight, a blue laser is directed through

About the capability of the engraver Due to the size limit of DVD drives, the machine can only engrave within an area of 36 mm by 36 mm.. So it can do little pieces of wood, plastic board or part of iPhone cases, but not any larger. The laser used here is 200 mW 650

This valentines we made this wooden Harp and used Laser and Light Dependent Resistors (LDR’s) to play music. I will not be showing you how to make the wooden structure, but you can find the images with exact dimensions if you want to use them. I have used the code of Piano Stairs which I

I wanted a decent size portable display for my Raspberry Pi’s that I could easily pack up and take to work, friend’s houses, gatherings, and Tech Shop. I bought an inexpensive 10.1″ LCD display from eBay and using a laser cutter, 1/8″ birch plywood, 1/16″ clear acrylic, and some hardware, I made a case to
