Mathematical relations and patterns are found all around us in our daily lives as well as in nature. These patterns can range from simple to complicated and harmonious to chaotic. No matter what type of pattern we encounter, these geometric figures have intrigued so much that and we have developed a fond appreciation of…
This is an user friendly tiny digital table clock where user can access all basic functions of clocks including setting alarms, viewing temperature, viewing date, setting date and time, etc. It has a buzzer for alarm and four push buttons (Menu, Left, Right, Cancel) for user interaction. It can be powered by a standard…
Stopwatches are very useful in several applications and made by yourself using an Arduino, it is really more interesting! This project is really simple, easy to be assembled using few components and has an excellent accuracy and responsiveness including the following features: The stopwatch shows the time in minutes, seconds and tenth of seconds. The…
This instructable video is all about how to monitor the Quality of water, interns of monitoring the level of water, the temperature of the water and its surrounding, the turbidity of the water (how clean the water is) as well as the PH levels of the Water. So this system monitors all of these…
Let’s learn to control our home appliance using the TV or DVD player remotes or smartphones phones like Xiaomi which is having an inbuilt IR transmitter. We are using a Relay channel with an Arduino and IR receiver to control our home appliances. More info
Small wood lathes don’t typically come with an RPM readout, so after obtaining such a machine several months ago, engineer Zach — also known as ‘byte sized’ — decided to build his own custom display. The device uses a Nano for control, along with a Hall effect sensor to pick up on four magnets attached to the…
3D scanners are amazing tools that literally let you turn everyday things into three-dimensional computer models. As seen on Reddit, if you want to make one yourself — using little more than a spare Android phone, Arduino, stepper motor, and 3D-printed parts — the AAScan by QLRO could be an excellent option.

Researchers in Thailand have developed a ZigBee-based wireless monitoring solution for off-grid PV installations capable of tracking the sun across the sky, tilting the panel hourly. The elevation for the setup is adjusted manually once per month for optimum energy collection. The prototype is controlled by a local Arduino Uno board, along an H-bridge motor driver to…
The South Florida Science Center recently commissioned a beautiful new 10” aperture refactor telescope. Its dome, however, was opened by hand; so in an effort to modernize this part of the setup, Andres Paris and his brother added a windshield wiper-style DC motor to automate the process. More info
Flip displays are an interesting piece of technology, physically moving segments into place that stay put until other information is needed. Michael Klements has been especially fascinated by these devices, and after inspiration from another project, he decided to craft his own. His version utilizes 14 micro servos to flip segments into a visible position,…
https://youtu.be/7rnk2qte4-I SunVox synth software allows you to create electronic music on a wide variety of platforms. Now, with his ZT-2020 project — which resembles a miniature arcade game — YouTuber “fascinating earthbound objects” has a dedicated input scheme. This cabinet prominently features a wide array of buttons, a directional input from a PlayStation controller, and…
Lasers are awesome. Glow-in-the-dark surfaces are, too. As seen here, Justin and Brett were able to combine the two into an excellent drawing machine made from scrap materials and discarded wood. Their device uses a pair of gearmotors under Arduino control to actuate a rack-and-pinion gantry system over a canvas painted with phosphorescent powder. A…
