LoRaTube: Long-Life LoRa Repeater in a PVC Tube (No Lithium, No Solar)
Sep 19,2025
That’s why a repeater is necessary: to fully exploit the available link budget and reach long distances, the transmitter’s location must be carefully chosen. By placing the repeater at a high point — a hill, tower, or treetop with a clear line of sight — a single module can cover several tens of kilometers without exceeding the legally allowed transmission power. This strategy is at the heart of the LoRaTube concept: keeping a compliant, very low-cost, discreet, and autonomous transmitter (...

solar panel system
DN Sep 11,2025
The solar panel system rotates according to the sun, collects data and sends it to the computer, including the power received with the current intensity and voltage, then sends all the collected data to the access software, from which it is possible to know the amount of electricity received each day, month or year. This helps people control the amount of electricity consumed to meet the necessary tasks.

Solar Power MPPT Control Li-ion Battery Charger
Manoj kumar Mar 03,2025
When talking about standalone single cell battery chargers only one popular name came into my mind that is our versatile Li-Ion/Li-Po TP4056 battery charger. Which is vastly available and has a lot of features related to battery protection. The lithium batteries are easily available in the market with proper charging solutions, but when it comes to solar changing a few microcontroller projects can be seen over the web. I want to create a standalone solar battery charger module, and luckily I fou...

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...
