Summary This is a description of how I designed and built my UV exposure box. After experimenting a bit with dry-laminate photo-resist and liquid UV hardened solder mask I decided to stop trying to improve my toner transfer technique and rather build a proper UV radiation unit for making printed circuit boards. I wanted it […]

In a time where change is inevitable, businesses need to stay ahead of the curve to remain competitive within their industries and ensure the COVID-19 pandemic doesn’t cause a decline in success. Large scale companies are looking for ways to manage services from one central console, as they prepare for a post pandemic working environment.
Description The AS3935 is a programmable Lightning Sensor™ IC that detects the presence and approach of potentially hazardous lightning activity in the vicinity. It detects intra-cloud activity as well as cloud to ground flashes, often enabling risk to be evaluated for approaching storms. The US National Weather Bureau suggests the 30-30 rule when lightning is imminent (When a flash is seen

The IEEE 1394, which is also called FireWire by Apple, is an interface standard for high-speed serial bus for connecting devices to a personal computer. Like USB, IEEE 1394 is a serial bus that uses twisted-pair wiring to move data around. However, USB is limited to 12Mbps, IEEE 1394 currently handles up to 400Mbps. The

a digital signage player for displaying photos and text or playing videos or PowerPoint slides but AI was introduced and it became possible to use a digital signage system for advanced techs like facial recognition where it can anonymously capture more personalized information such as gender, age, and even mood, as well as for weather
UC3844 is popular current mode controller which is commonly found on DC-to-DC converter circuits and switch mode power supplies. This motor speed controller is also based on UC3844 and it is specifically design to drive 20V – 24V DC motors. In this given configuration UC3844 produces (approx.) 50kHz to 240kHz PWM output and this range

4D Imaging using radar technology provides good resolution and field of view for scanning applications. Vayyar’s single-chip platform is a good example, as it integrates multiple antennas using RoC for improved 4D Imaging. The multifunctional single-sensor platform fulfills the Euro NCAP safety requirements using its 4D Imaging feature. The chip comes with 48 transceiving antennas on a single package, hence

What is it? The Small Weather Station is a battery-operated, wireless, weather station. I have been working on the project for almost a year now, and now I have an unshielded prototype that is partially functional. I say partially functional, because it does not have any wind/rain sensors installed, only the connections for them. So
