I came up with a nice (from my own standpoint) circuit arrange that tester each and every pin of my Arduino-compatible board:- Pins 0 and 1 = Serial communication with a PC, through the "Serial.print()" command- Pins 2 and 3= an LED connected between...

This project is inspired by the nostalgia for portable devices like USSR "Электроника МК-90" and Texas instruments TI-92. END USER REQUIREMENTS (An Ultimate Hacking Machine):o Retro look and feel. PWR,...
After the explorations with #YGREC-РЭС15-bis, I reached several limits and I decided to scale it down as much as possible. And this one will be implemented both with relays and VHDL, since the YGREC8 is a great replacement for Microchip's PICs....
As usual, the problem isn't a new problem, and this isn't a new solution. But I will describe it to help someone doing the same. With this project I've made a wifi infra-red remote control for my Daikin air conditioner. In these schema you can see...
Blinking LEDs, what can be easier, right? For a recent project I needed to multiplex 2 sets of 6 LED each. The circuit schematic has the LEDs driven by 6 pins on an Arduino plus two pins to activate one bank or the other. LEDs are these ones from LCSC....
1 Intro The Enecsys Gateway is a Zigbee gateway allowing communications between the Enecsys microinverters and their monitoring backend. The Enecsys company is unfortunately defunct since 2015 and their DNS domains have been taken over by a UK enecsys...
This idea was born when i saw this project years ago: https://hackaday.io/project/170961-resistor-color-code-clock-v10 NOTE: There is a bug showing resistor values under 100 since gold nor silver can be displayed. AND the multiplier seems to be...
Today we present the FlameWheel Robot assembly tutorial and quick-start guide! It is rather difficult to assemble this robot without guidance. Feel free to refer to my introductory tutorial today.Flamewheel (A 2WD Remote Control Robot) is part of our...
Hardware ESP-32: The ESP32 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. This ESP32 IoT Module combines Wi-Fi, Bluetooth, and Bluetooth BLE for a variety of diverse applications. This module comes fully-equipped...
Really Mike, why a TMD-3? Before I talk about what TMD-3 will be, I would like to give a brief overview of Turing machines, the TMD-1 and TMD-2 designs, and what prompted me to want to do a TMD-3. Turing Machines 101 The Turing machine was invented in...
In the Maker community there are projects to make Virtual Reality headsets to use with the PC, but these are for wired use, so there is room for a wireless solution that does not involve using a cell phone. Currently the best: https://hackaday.io/project/187343-easy-pancake-lensesAnd...
From OpenCores PDP-8 page: Features In this FPGA implementation, the PDP-8 CPU can be configured to emulate the instruction execution of a PDP-8 (Straight-8), PDP-8/S, PDP-8/S, PDP-8/I, PDP-8/L, PDP-8/E/F/M, PDP-8/A, HD-6100, or a HD-6120. The...
Compact-size-PCB-for-Arduino-projects This is multipurpose PCB specially design for arduino projects so that we can connect multiple components at once with arduino Those who ever worked with arduino they know the pain of connecting multiple components...
