Color Classification on ESP32Cam

2020-04-14T16:42:00Z

Introduction In machine vision systems, image processing techniques can be used for color measurement, color matching, and color-based recognition. For decades, companies have been using vision systems for inspection purposes when their produ...(read more)

Candle in the wind

2020-04-13T22:00:00Z

Introduction This project is a simple game that inspired my 4-year-old son. I saw him spellbound looking at the flame of a candle, the candle of a birthday cake. I tried to make him play a bit with LEDs but the charm of a flame that moves as if it w...(read more)

This is a LED light Organ project meant for summertime evening fun. Imagine grilling on your house deck, patio, or beachfront..........relaxing (or rockin' and rollin' ) with a stereo playing, and 100+ feet (35 meters) of deck railing ( backy...(read more)

Simple light flicker meter

2020-03-08T16:44:00Z

The basic idea was to create a simple device which allow to compare the quality of light sources e.g. LED bulbs. I have used TSL250R IC containing photodiode and operational amplifier with configured feedback loop. This IC is optical sensor which o...(read more)

Photonics: Wireless Communication with Infrared

2020-02-22T07:18:00Z

This blog describes how infrared receivers such as the Vishay TSOP38238TSOP38238 work and rather than using a library or built-in hardware it describes an oddball way of wireless communication of my own design. A microcontroller will be used to turn...(read more)
