The six-pack yokes or rings are a set of connected plastic rings that are used in multi-packs of beverage and beer cans in the USA. These are discarded carelessly by most Americans and even though you might put them in recycle cans (if your city has the facility like mine does), they somehow end up […]

Creating your own light show
With programmable LED strands, strips, and rings, it’s not only satisfying and fun but also a solid learning experience for any enthusiasts. Besides, who can ever get enough of tinkering with LEDs? In this project, I connect a 24 pixel ring LED module to an Arduino board, then wrote some light effects functions in the […]
Common birds of WA state
The birds most likely to capture our attention with their songs during early spring in the Pacific Northwest are not migratory visitors, nor exotic strangers, but good old perennial neighbors. – Seattle Times On that theme, from our backyard to the parks, to the outskirts of our immediate cities, most of these birds are very […]
Arduino: Build a custom nightlight
In this project, I built a night light with exact parameters of my own liking using simple components. I wanted the light to come ON when I detect the ambient light to be an exact value customized for my room, stay ON exactly as long as I want, and/or blink as I wish. Additionally, I […]
Arduino: Photoresistor and Servo motor working together to indicate light
This fun project is to visually and mechanically indicate day/night or light/dimness around with the help of a photoresistor that reads the light values. And that’s connected to a motor (a servo) which has an arm/arrow connected to it and it moves to certain positions depending on the light sensed by the photoresistor. Lastly, the […]
Arduino: Building a music tempo controller with simple components
In this project, I built a simple system where we can play a tune/music through a speaker (sound/tone is of our choice) and while it’s playing, we can control the tempo in real time. For the speaker, I used an inexpensive passive buzzer hooked up to a 10K resistance potentiometer. I insert a turning knob […]
Conversation over phone that you can “feeeeel”!
I can see some form of this being actually quite useful and popular even as a novelty. Change the form factor (to less clunky) that can be added to most phone, add horizontal motion for the feelers. I can imagine some people making creative uses for the tongue add-on.
Arduino: Building your own dimmer at home
This mini-project is to get a lamp to dim or brighten on command. In this case, we’ll hook up a regular LED to a potentiometer module, which when turned clockwise will increase the brightness of the LED lamp, or dim it (and all the way to “off”) when turned counter-clockwise. This is exactly how the […]
Arduino: LED color fade project
Here’s a straight-forward circuit with a LED light that’s controlled by my code downloaded to an Arduino controller’s chip running the “light show”. It starts with red color of LED set to max RGB(255,0,0)…then slowly dims the red as green value is increased incrementally to max. Then green is dimmed while blue is increased incrementally […]
An experimental music production: Arrival
It’s been years since I played instruments, recorded, and wrote lyrics. Most of the gadgets and music instruments have been mostly gathering dust. This is mainly due to work and other responsibilities of life that sucks away the artistic motivation. Same situation with my sketches and paintings. I will however come back to them, it’s […]
