Electronic, 3D printing and embedded programming
Here is my Arduino battery tester, designed to explore the performance of various types of batteries, including 18650 and acid-based ones. Successfully tested even with a 6V lead-acid battery with a capacity of 4.2A, this device provides battery capacity readings in milliampere-hours. In fact, it’s an old article that I had never published before, but I have revisited and decided to publish it now.
The article provides an overview of the SunFounder RasPad 3, a device that converts a Raspberry Pi into a versatile tablet. It covers the assembly process, including integrating a Raspberry Pi 4 and an M2. SSD. The guide concludes with instructions for setting up a multi-boot system using PINN, allowing users to alternate between various operating systems for different applications.
What started as a simple review of the TS7-Pro display for a project, has evolved into a comprehensive examination of a Raspberry Pi setup. This setup features the TS7-Pro display, a night vision camera, a SunFounder PiPower module, and a DIY 3D printed rechargeable battery pack. Witness how the night vision camera effectively captures detailed images, even in low-light conditions.
I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify the status to the server.
We are going to assemble the Server PCB.

Here, we are going to look at the Server software.
SSD1306 IC is used for the most commons OLED display is a single-chip CMOS OLED/PLED driver with controller for organic / polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64 commons.
We will now render images and create a simple animation and take a look at the byte array generator.

We are going to use it with SPI and i2c and learn the basic function.
I’m going to explain a connection schema for a character display i2c adapter.
