Although you can buy analog tide clocks that have a single hand indicating whether the tide is high or low or somewhere in between, what I wanted was something that would tell me at what time low tide will be. I wanted something I could glance at quickly without having to turn it on, or push any […]
Everlasting flower for your everlasting love. A perfect not-only Valentine’s day gift to your loved one. This mechanical tulip will bloom into any color possible with just gentle touch of your hand. Its six petals will slowly open and light up. When petals are closed they create incredible ambient light with leaf patterns. Step 1: […]
This project is a small, battery-powered LED ring that fits perfectly inside of your Rav Vast drum. It uses color-changing RGB LEDs and a microphone that allows you to change the color or pattern with changes in volume. You don’t need any special skills for the construction (though you may pick some up along the way) Step […]
This project came to my mind when doing my MEM (Mechanical Engineering Measurement) project, a subject in my B.tech. The idea is to measure the angular velocity of my bicycle’s wheel. Thus knowing the diameter and the all time mathematical legend the pi(3.14) the speed can be calculated. Also knowing the number of time the wheel has […]

The goal of this instructable is to explain how I made a wifi-connected light switch (also called remotes further). The goal of these remotes is to turn on and off several wifi-connected relays. The relays are not explained in this instructable. They are explained in a separate instructable that I made in the past: ESP8266 Wifi […]
There are some projects where you make a functional thing or practical thing. There are some projects where you make a beautiful thing. And then there are projects like this where you decide to slap a razor blade and balloon on some robots and battle them, Mario Kart style 😀 I’ll start this by saying […]
With Valentines Day approaching I thought it would be nice to make a project for the people who are special in my life; I thought the people of instructables would probably like it too! I’ve designed a ~100mm x 100mm or ~4in x 4in PCB heart. It uses the Attiny85 SMD microprocessor as the brain. […]
Note from the author: In an effort to get this ready in time for the safe and secure challenge, I have had to make a few compromises to my box, but that doesn’t mean you have to! I have left my original ambitions in the text, as inspiration for you to make the best Time […]
I have always enjoyed the various acrylic laser-cut night lights that others have made. Thinking more about these I thought that it would be great if the night light could also double as a form of entertainment. With this is mind I decided to create jigsaw puzzle that would fit into a thin box that […]
