USB BELL RINGS IN CUSTOM TERMINAL

Old TeleTypes and even typewriters had bells. Real bells. So that ASCII BEL character is supposed to make an honest to goodness ringing sound. While some modern terminals make a beep from the computer speakers, it isn’t the same. [Tenderlove] must agree, because the turned a Microchip USB to I2C bridge chip into a HID-controlled bell. The only problem we see is that you have to have a patch to your terminal ...

Keyboard Controlled Model Train V2.0 | PS/2 Interface

In one of my previous Instructable, I showed you how to control a model railway layout using a keyboard. It did great but had a drawback of requiring a computer to operate. In this Instructable, let's see how to control a model train using a keyboard through Arduino. So, without further ado, let's get started. Step 1: Watch the Video https://youtu.be/94yJJhv92OE Step 2: Get All the Required Stuff ...

PasswordPump Passwords Manager

This is v1.0 of the PasswordPump, a USB device that manages credentials for up to 254 accounts. Credentials (account names, usernames and passwords) are stored ONLY on the device itself, on two removable EEprom chips using military grade encryption (AES-128). They are not stored in the cloud or in a file on your computer where they are more exposed to hackers. Credentials are backed up on the device itself; ...

BUILD A MULTISENSOR SHIELD FOR ESP8266

In this project you’ll discover how to design and create a Multisensor Shield for the ESP8266 Wemos D1 Mini board. The shield has temperature sensor (DS18B20), a PIR motion sensor, an LDR, and a terminal to connect a relay module. We’ll start by preparing all the hardware and then program it. Watch the Video Tutorial This project is available in video format and in written format. You can watch the vid ...

IOT Lunar Rover Raspberrypi+Arduino

https://youtu.be/mcdEGQTxE88 This project is inspired by the Indian moon mission Chandryaan-2 Which will take place in September 2019.This is a special mission because they are going to land on the spot where no one has every landed before.So to show my support i decided to build the actual rover based on the images of the rover online. I was restricted by my 3d printers size so i had to do some slight modi ...

Heart-rate monitor on a small OLED display with MicroPython

Pulse sensors have become popular due to their use in health-monitors like the Fitbit. The sensors used are cheap, simple and pretty reliable at getting a reasonable indication of heart rate in daily use. They work by sensing the change in light absorption or reflection by blood as it pulses through your arteries — a technique jauntily named photoplethysmography (PPG). The rising and falling light signal ca ...

Arduino Password Unlock Door Security System

Hello! In this Instructables guide I will show you how to make your own password unlock door system by using the Arduino uno board. I made my own circuit by using the ATmega328 micro controller but this is an optional step. In this guide I will help you to make it easily on breadboard by using the Arduino uno board, and I will give you some extra tips on how you can make your own Arduino-based custom circui ...

Arduino Uno Xylophone

This xylophone uses the Arduino Uno and a multiplexer to identify when one of eight keys are struck, and play that sound via midi sound on a computer. An optional part of the instructions also allows each key to light up with two LED lights at the same time the xylophone is struck. These steps outline what I have done. Step 1: Necessary Parts Arduino Uno9 V battery with Arduino adaptorArduino to USB connect ...

Using NXT Components With a Micro Controller

This is a guide to using the motors and sensors from the LEGO NXT set with a Parallax Basic Stamp II or BS2.  However, rather than just providing schematics and sample code for the BS2, I'll be providing some theory on how the sensors work as well.  This way, someone using an arduino or other microcontroller should find this guide at least somewhat helpful. My two main sources of information areTh ...

70W soldering iron controller

Theory of operation In series thermocouple soldering iron have a thermocouple in series with their heating element and thus only have two connections (actually one more which is electrically connected to the tip for ESD purposes). When a voltage is applied to the two terminals the tip heats, when unpowered the thermocouple voltage can be read. This controller uses a skipped variable puls modulation to keep ...
