Laser harps are musical devices with laser beam “strings.” When the beam is blocked, a note is played by the instrument. Usually laser harps have the beams travel vertically in the shape of a fan or vertical lines. In this project, I built a laser harp with stacked laser beams that propagate horizontally. The beams

Berry Racer is a game that I came up with and programmed using Arduino’s Software. The game is run on a Teensy microcontroller which is connected through a custom PCB (Printed Circuit Board) to a Screen, a Joystick, four buttons, and a piezo speaker. The board can be powered through the micro USB port on

In this project, we will be making a benchtop pH meter using the gravity analog pH circuit and probe from Atlas Scientific and an Arduino Uno. Readings will be displayed on a liquid crystal display (LCD). MATERIALS 1 – Arduino Uno 1 – Gravity analog pH sensor 1 – pH probe 1 – 20×4 LCD module 1 – 158x90x60mm Enclosure

I designed and built a Geiger Counter – a device that can detect ionizing radiation and warn its user of dangerous ambient radiation levels with the all-too-familiar clicking noise. It can also be used when scouting for minerals to see if the rock you found has Uranium Ore in it! There are many existing kits

The brachistochrone curve is a classic physics problem, that derives the fastest path between two points A and B which are at different elevations. Although this problem might seem simple it offers a counter-intuitive result and thus is fascinating to watch. In this instructables one will learn about the theoretical problem, develop the solution and finally build

Introduction: On one of my weekly pilgrimages to Lowes (as any devout Kansan does), I found a sad little plant in the Gardening Department: a Janet Craig Compacta. The poor little guy looked lonely and dehydrated. We clicked right away and immediately I knew I had to take him under my wing. There was one

This instructable shows how to build a rather special pool sensor measuring the pool temperature and transmitting it via WiFi to Blynk App and to a MQTT broker. I call it the “Crocodile Solar Pool Sensor”. It uses the Arduino programming environment and an ESP8266 board (Wemos D1 mini pro). What’s so special about this project?

One of the things I look forward to with summers in Pennsylvania are fireflies in my backyard. I recently taught myself Adruino programming for the purpose of making this simple project. It’s a great program to start with and is easy enough for any programmer, novice to expert, to build, modify and have fun with

The inverted pendulum is a classic problem in dynamics and control theory that is generally elaborated in high-school and undergraduate physics or math courses. Being a math and science enthusiast myself, I decided to try and implement the concepts that I learned during my classes to build an inverted pendulum. Applying such concepts in real life not
