Update 2016-09-26: SD card access now worksThis is one of the first runs of my memory dumper "cartridge" reading data off SD card. The code reads the master boot record, then parses the partition table etc and finally reads and shows the contents of...
What a hot day it is! Too hot to drive and ride and I am thinking of making a temperature measurement sensor. MLX90614 (a noncontact IR temperature sensor) on hand, let’s do it! Hardware &software in need Hardware in need Hardware ListFireBeetle ESP32...
A very important part of the PIMP project is the Keyboard. Without a keyboard, no notetaking capabilities. The Blackberry Q10 keyboard has a basic keyboard matrix and needs 5 pins for the rows and 7 pins for columns. The first iteration of this controller...
The Fluxamasynth is well suited for making musical appliances. One example is from a series of Soundboxen; this one is inspired by Brian Eno's Music for Airports tape loops. For this appliance the length of each loop is determined by one of the potentiometers....
Introduction Many IoT developments these days, integrate and operate with Amazon's Alexa to provide voice interaction. In this project we are going to look at how we can integrate Alexa with our Ultra96 design. This means we can develop applications...
We thought a lot about the user interface for our charging station. After ditching the infinite mirror idea, we wanted something simple and elegant, inspired from the Tesla wall charger, so we started experimenting with RGB LEDs strips. The first...
Serial connection over USB for retro computer? Why not! I was asked by someone in /r/beneater community to describe how to build USB -> UART interface using FT230XS chip, as this exercise might seem a bit intimidating for someone doing it for a first...
This project was developed in partnership with Robô Lúdico School and JLCPCB Factory that offers 5 free PCBs of Arduino Compatible Board. I want to teach you how to communicate with 3 Arduino boards or up to 32 on a communication...

DIY-Calculator-using-Arduino Performing simple mathematical operations was the basis on which one of the first computing machines designed by Charles Babbage who is considered as the father of computers was a steam-driven machine used to compute tables...
Introduction This tutorial will teaches you how to build a weighing machine with the Arduino using a load cell and the HX711 amplifier. First, you’ll learn how to wire the load cell and the HX711 amplifier to the Arduino to build a Weighing Machine....
Just over a week of chatting with ChatGPT-4 and I have working code! At least it works on wokwi.com... I still need to load it to the real hardware. It works, but there are a few things I don't like:The array of "all leds" doesn't include the simon...
How Everything Works? The NodeMCU is connected to a bunch of sensors, a relay module and RGB LEDs. It is connected to Blynk app on a smartphone via WiFi, which sends all the data and allows you to control your home. Raspberry Pi is also connected to...
