In todays modern world there are many energy sources and storage methods available. The most design and powerful storage technologies are very expensive and controlled by patents. While there are many options for battery packs available there are...
After some final polishing of schematics and board, they're ready - see the project's File section ;)Shortly, about new design features and intent:This PCB is based on two big components:1) ADP5091/5092 - Ultralow Power Energy Harvester PMUs with MPPT...
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...
I developed this idea while finishing work on the DC-converter section of my Solar Charger project. I needed an MPP algorithm for the firmware and didn't want to adapt the work that I had previously done with my Prototype MPP Charger -...
The electronics part of the solar tracker is quite simple as we reuse existing components which are mostly only integrated all together on a custom PCB. Here is the schematics : The heart of the system is the Lolin32 ESP32 breadboard. It is driving...
Over the last few weeks I've been searching the web trying to find the right balance of parts and cost in order to meet or exceed the $1/W budget. I've compiled a long list of possible configurations in an Excel sheet (see sample below) and have narrowed...
It's a great song by the way.As discussed in my previous project log, I was able to remove the ADC and DAC otherwise needed to perform the MPPT algorithm, vastly simplifying, if not outright eliminating the need for a microcontroller. The motivation...
My stock was getting low, so I faced the question whether I would just build more of the rev 5 boards, or if I was going to make any changes.I'm very happy with the LiFePO4wered/Pi+, and my customers seem to be happy with it as well, but one thing that...
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...
One long-standing goal I have had for my thermal cameras was to record events such as a wildlife in our driveway at nights (we think it's pretty busy out there) by detecting parts of the image in certain temperature ranges. Sort of like a...
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...
This project log is about the design and testing of a new solar harvesting board around the AEM10300. I am already selling three solar harvesting boards around the AEM10941 PMIC from E-peas (this, this and this). I really liked the 3.3V regulated output...
I started with the following components (prices include shipping): 2x L02M100N-1 monocrystalline solar panels from ECO-WORTHY. $90 each. Mine have slightly different specs due to being purchased a year apart. 1x PG-12V55-FR Powersonic 12V 55Ah Sealed...
