At first, we need to prepare the environment for ESP32 development board programming in arduino, and you can cheak this guide.This is a library for our Monochrome OLEDs based on SSD1306 drivers. #include This library allows you to communicate with...

It's have simple schematic, for save pins I used Charlieplexing(35 components in total): https://en.wikipedia.org/wiki/CharlieplexingIn this project i use for charging 12 light sensor BPW34S, on clear sun one cell make 0.5-0.6 V and ~2 mA, connect its...
I will soon reveal what the purpose of the end product is supposed to be, however, for now the journey is the goal. I've become fascinated by machine learning and then about the idea of using it on microcontrollers only about 6 months ago, so it...
For my first trials I decided to use the TinyML kit: which contains Arduino Nano 33 BLE Sense and the OV7675 camera (kit). I use the following libraries on arduino IDE:Arduino Mbed OS Nano Boards v3.0.1Arduino_OV767X v0.0.2Arduino_TensorFlowLite (from...
Some days ago a friend told me about the heaters from Vevor and after some search I found this page very promising: http://afterburner.mrjones.id.au/ So I hoped the Vevor ones have the same protocol structure and things would be quite easy....
Today I started to connect the bus to my PC. A USB/USART adapter from FTDI was my choice since I got tons and various PCB's laying around. The FTDI can be configured for RS485 to enable a IO when you're sending data. I tried the interface with the two...
Starting project by learning more about eggs.. I'd like to figure out how to create a nice 3D printed egg shape that can hold a circuit board, battery, and motor assembly. I'll start by printing off some free variants from thingiverse. Ultimately I want...
The system block diagram is relatively simple. The egg moves using a stepper motor and there is a microcontroller and motor controller used to generate the PWM signals for the stepper. A USB interface allows for re-programming of the microcontroller....
I started writing some programs to control the DRV8825 using a few small embedded boards I had lying around - the Metro by Adafruit and Arduino Uno both of which are based on the ATMEGA328P processor. I went with these because I wanted something...
The first full size egg finished printing after 40 hours. This was a fun first attempt and my son loves to kick it around the house. I ordered some rainbow colored filament for the next attempt. Things to change: Decrease wall thickness to no more than...
We're starting to finalize some of the bigger pieces of this project, so we're excited to start sharing our progress! We've got the geometry and LED arrangement set, now we're testing our electrical design and getting started on writing some animations....
Obligatory title. This project has already been underway for months and will likely continue to evolve for as long as I can. Since my workshop is in my basement with no windows, I wanted a way to keep an eye on the outside world. I don't...
