The Concept
I've long had an idea for a super basic color sensor. I'm not talking about the fancy-schmancy color sensors like this one, but rather something more basic... much much more basic...
The concept here is to use a humble RGB LED and a phot...

Introduction
When the photonics competition was announced I had no idea what I could do as an entry. Reading through the brief the only parts I have that I could usefully...
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...

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...
nanoSense:Motion is an Ultra-Low Power Motion / Human Presence Sensing device with Bluetooth Low Energy connectivity.
The device is based on the Kemet PL-N823-01 Pyroelectric Infrared Sensor and the OnSemi RSL10 Bluetooth Low Energy SoC.

If you are into home automation or just starting with home automation, then this is a simple project to undertake. Basically as part of this project I am putting together IR break Beam IFTTT node, which send a message to the IFTTT cloud based on whi...
Having successfully created my own 4 x 4 LEDGrid display using some green LEDs generously donated to me by Element14 recently (LEDGrid Display #1 : First Working Display ) I decided to try for a double lot of photons for the Photonics Project14 Chal...
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...
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...
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...
