RGB LED Color Mixing & Crossfades – A Quick Primer
When you want beautifully smoother color transitions, a better way to do it is to try HSL or HSV rather than just driving LEDs via RGB colors. So, this little post is about controlling RGB […]

Some time ago I had posted a couple of Arduino projects that work in conjunction with external power supply circuits. If you have not already got those ideas yet, you may simply go through the […]
I bought a cheapo Chinese automatic LED nightlight a while ago. Working on this “automatic color changing night lamp” is pretty simple. A photoresistor (LDR) turns the LEDs on when it sees darkness and off […]
Selfie Stick is a common smartphone accessory nowadays! The word “selfie” first appeared in an online forum in 2002, and in 2013 it was named the Oxford Dictionary Word of the Year, defined as “A […]
This post is about the construction of a multi-colored matchbox-sized magic lamp for kids using a simple and cheap microcontroller board. The most interesting thing about this build is that it does not require any […]
Whether you are a soldering artist or not, checking your soldering iron out should be a steady routine. So, it’s always good to have a soldering iron tip thermometer handy. There’re different types of tip […]
This little post is about the quite popular FOTEK Solid State Relay (FOTEK SSR). First note that FOTEK is a well-known brand in China and a FOTEK SSR will last a long time. But sadly, […]
I made this as a Christmas present last year. This is a small color-changing RGB LED orb light controlled by Raspberry Pi Pico. I got the inspiration for this project from the Chinese-made USB-rechargeable color-changing […]
Since every machine has its own vibration signature, drifts in a machine’s vibration can indicate potential faults. There’re multiple types of vibration sensors available to keep tabs on a machine’s vibration, and a widely used […]
Prolonged blackouts have always been an annoyance, but with the help of today’s portable inverter lamps/bulbs, tackling them has become much easier. Below you can see such an affordable LED Inverter Lamp from Osram (India). […]
