Sun Tracking Smart Clock Using Raspberry Pi Pico
Kundan Feb 28,2025
Have you ever had the misfortune of working in rooms without windows? This project will get you the next best thing to a window. This clock can tell you visually where the sun is at all times of the day, and how much daytime (or nighttime) is remaining - all without the need for external communication. This project combines astronomical mathematics from ~80 BC, timekeeping technology from the 17th century, and all the cool hobby electronics and PCB tools available to us in the 21st century. Wat...

Tim's Solar Motor Driver
Jackson Feb 11,2025
This is a little solar DC Motor Driver.It uses two LDR (Light Dependant Resistor) sensors to track the movement of the sun.There is no microcontroller, it uses an Op-Amp (Operational Amplifier) as a comparator to switch relays to drive a motor.With the correct rated relays A Large DC Motor can be driven.I totally messed up in the video above trying to explain the Logic Gates off the top of my head, due to my memory issues (it is what it is).You may want to watch the video below first, so that yo...

1-4X 50Watt Solar Switch Board v1.02
Bucks Nov 09,2024
You can plug 1 to 4 solar panels in on the parallel side of the board or on the top there is two options for running in series. 2 in series or 3 in series. I use 2 different controllers for reliability, the series outputs to one controller that steps down and the parallel runs to another controller that steps up.More about this soon on my YT channel. Find me at YouTube@Ro-Bucks

MPPT Solar LIPO Battery Charger
Manoj kumar Oct 30,2024
I was just charging my Li-ion battery manually with my IP2312 charger, the high current version I have made previously. Then the idea of charging batteries with solar with an automatic cut off option comes to my mind. What I can do is simply hook this IP2312 charging module with solar with a diode in series for reverse voltage protection. But this seems a very unprofessional and inefficient idea. And I found CN3165, a solar powered MPPT based single cell battery charging IC with protection featu...

Simple Arduino Solar Radiation Meter for Solar Panels
Pavleski Sep 12,2024
The sun provides more than enough energy to meet the whole world’s energy needs, and unlike fossil fuels, it won’t run out anytime soon. Solar power cell is are renewable CO2-free power source that convert Sunlight into Direct Current (DC) electricity. Solar irradiation is the power per unit area received from the Sun in the form of electromagnetic radiation, and is typically expressed in watts per square meter (W/m²). This data is used to determine the potential for solar power generation, and ...

Solar Powered RC Catamaran
Model Maker Sep 12,2024
I built a solar-powered catamaran using glass-fiber laminate for a watertight hull. I faced challenges with the mold and had to destroy it to free the hull. I also added water jet pumps, wooden ribs, and aluminum parts sponsored by PCBWay. Finishing touches included a 3D-printed deck, painting the hulls, and using a frame to connect them. The boat is powered by a 100-watt solar panel.

DIY Solar Mason Jar Lamp
Green Energy Aug 26,2024
Making a solar mason Jar Lamp is not just a fun project; it’s also a fantastic way to learn about renewable energy and how we can use it in our everyday lives. I’m excited to guide you through this DIY project where you'll create your very own solar-powered mason jar lantern. This project is an upgrade to my earlier Instructables. I have upgraded the PCB so that it now includes an integrated battery holder, eliminating the need for a separate holder. The building process is more straightfor...
