DeepPlankter An autonomous wave and wind propelled drone boat. It uses free energy in the surrounding environment to sail for a very long distance. It relies on in-air free-rotate wing and the underwater wings to provide propulsion and solar panels to...
After using these fantastic little ICs in my rock (see my other Hackaday.io project!) I thought that they would be perfect for the square inch challenge.Taking further inspiration from "The Signal Path" vblog (http://thesignalpath.com/blogs/2013/01/03/tutorial-and-experiments-on-energy-harvesting-ics/)...
Another driver for the project was the fact that I wanted to make a "mobile" satellite receiver groundstation. I could always make a little box with all the pieces in it, but wouldn't it be cool if it was all attached to a hat? There are a few upcoming...
The design as implemented from the original idea has the following features: Processing system ESP32-WROVER-I module with 4 MB Flash, 8MB PSRAM and external U.FL antenna connectionMicro SD card slot for data storageSeparate NXP MKL17Z32VFM4 ARM Cortex-M0+...
Weather Station using PSoC-6 as its heart. Records the wind Speed, Direction, and Rainfall. Also the temperature, and humidity, Ambient Light level, UV level, RGB Color, and High Dynamic Range light. The weather data is provided as daily...
This is a product for sale at Tindie that I designed and use in various projects, including my SensorTile project where I have described its performance in detail. From the Tindie product page: This is a small (0.5 x 0.5 inch) breakout board for Texas...
Functional Description The circuit in this project contains two power circuits. The first is a synchronous buck converter, controlled by a microcontroller carrying out MPPT, to send power from a 2 watt, 6 volt solar panel into a small lithium battery...
Power Supply First the requirements: DeviceVoltageLoadPC12V200W Max (~30W at idle)Kraken SDR 12V/24V (USB)12WScreen5V (USB)5W Over-provisioning to 300W at 12V means I should expect to draw less than 25A, and at 24V just 13A. Since I want to be able...
This project was born from a real world need to send data from my rooftop solar PV system back to my home server so I could keep a track of how the system was performing. Datalogging the output on a minute by minute basis was easy enough, however,...
The main body of the UPS provides power management and voltage conversion only, relying on external power sources to supply between 7 and 32V DC. This gives me a lot more flexibility to expand the batteries as I salvage them from other UPS's, or do maintenance...
Main characteristics of SolarUPS uninterruptible power supply units: Constant, uninterruptible power supply, with stabilized DC output, independently from the charge level of the battery.Very efficient use of the energy coming from the solar panel for...
The purpose of this project is to develop, study, and refine the Perturb & Observe (P&O) algorithm for use in a charger that behaves like an automotive charging system: one that works to maintain a constant bus voltage with the battery...
Versatile stand-alone or as a Module While this project started as a stand-alone solar charger, is is nowadays often used as a module in larger projects. The prime example of this is MeshPoint, a WiFi hotspot for disaster and outdoor areas. That project...
Abstract SolPak is a rechargeable portable battery pack that can be charged via solar panels or AC mains voltage. The pack uses 18650 lithium ion cells and will be using the ADI LTC6813HLWE-1#3ZZPBF battery balancer/monitor chip suspected to be...
