Here’s a six word tragedy: My arduino needs four AA batteries. Really? Isn’t this 2012? Where’s my jetpack?!! Here’s a way to the future — a way to make a solar panel, from scratch, that can power any arduino off of sunlight or even light in your house. Sort of a peel-and-stick power source for your …

You know theremins, right? Those cool-looking boxes with antennae that produce noise without being touched? They are played by the likes of Jimmy Page of Led Zeppelin, and present in the soundtracks of countless films. Well, with this instructable, I will show you how to build an approximation of a theremin (in principle, at least) …
A fountain can make a nice decorative fixture for your garden. But it isn’t always easy to run a power cord out to where you want it. So I decided to run it on solar power. The system is controlled by an Arduino. This allows you to save energy by programming when the fountain will …
Imagine the ideal beach trip. The sun is shining, the skies are blue, the water is warm, and the humidity is low. You and your friends have everything you need to soak up the sun, sand and surf: a cooler filled with drinks and snacks, sunblock, flip flops, the coolest new swimwear, and the newest …
The following design is for a Solar battery charger ran by an Arduino Nano. It can handle a standard lead acid 12V battery, like for a scooter or a car. Furthermore the design has been tested and runs with 90% efficiency under 70ᵒC (158ᵒF). It can take up to 20V on the input site of …
Growing plants is fun and watering and caring for them is not really a hassle. Microcontroller applications to monitor their health are all over the internet and the inspiration for their design comes from plant’s static nature and the ease of monitoring something that doesn’t run around and sweat. I am relatively new to plant …

For my first IoT project I wanted to build a Weather Station and send the data to data.sparkfun.com. Small correction, when I decided to open my account in Sparkfun, they were not accepting more connections, so I choose another IoT data collector thingspeak.com. Continuing… The system will be placed on my balcony and will retrieve temperature, …
Introduction We aim to introduce young students to engineering and teach them about solar energy; by having them build a Helios as part of their curriculum. There is an effort in engineering to push energy generation away from the use of fossil fuels and towards greener alternatives. One option for greener energy is to use …
I always wanted to make a PCB and this is my first professional circuit board attempt. So before you decide to start this project you should know there could be some mistakes or it could be more reliable and compact. This design is not the most efficient and cheapest way to make a DIY MPPT …
Overview: The solar tracking device is designed to ensure that a flat panel with a solar cell is constantly aligned with the movement of the sun across the sky. It utilizes two light dependent resistors (LDRs) positioned on opposite sides of a fin to measure the light levels. By comparing the readings from the LDRs, …
