Save Water & Money With the Shower Water Monitor

Which uses more water - a bath or a shower? I was recently thinking about this question, and I realized that I don't actually know how much water is used when I shower. I know when I'm in the shower sometimes my mind wanders, thinking about a cool new projects idea or trying to decide what to have for breakfast, while water is just gushing down the drain. It would be a lot easier to reduce my water consumpt ...

Inverted Pendulum: Control Theory and Dynamics

https://youtu.be/xwXPipYmJ9A 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 only helps strengt ...

Arduino Magnetometer

What are we building? Humans can't detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic field vector at a location is displayed on a small sc ...

Arduino Fireflies

https://youtu.be/S8C5a9tcbgk 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 in only a few minutes. Let's get started. Step 1: What You'll Need. ...

The Brachistochrone Curve

https://youtu.be/1BdO8J0iynY 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 a mod ...

DIY Geiger Counter With an ESP8266 and a Touchscreen

https://youtu.be/rmFnbVB5gCM 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 and tutorials available online to make your own Geiger Counter, but I w ...

E-dice – Arduino Die/dice 1 to 6 Dice + D4, D5, D8, D10, D12, D20, D24 and D30

https://youtu.be/B-dnzLoZDlw This is a simple arduino project to make a electronic die. It is possible to choose for 1 to 6 dice or 1 out of 8 special dice. Choice is made by simply turning a rotary encoder. These are the features: 1 die: showing big dots2-6 dice: showing dots as well as total value (alternating)4, 5, 8, 10, 12, 20, 24 and 30 faced dice showing value and indicator for chosen dieanimation fo ...

Upright Laser Harp

https://youtu.be/_1oTBekbUT4 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 reflect off mirrors to form square shaped beam paths. With this ...
