This project is to create an Infrared Remote Control to control the Original Cybot received with the magazine Ultimate Real Robots, started back in 2001. Reason for making the remote:(a little history) Before the issue of the parts for the IR handset, Cybot was put into different modes by selecting DIP Switches. (There was no issue with Cybot while this was the case) When the IR Handset was issued, things c ...

My hobby and passion is to realize physics projects. One of my last work is about ultrasonic sonography. As always I tried to make it as simple as possible with parts you can get on ebay or aliexpress. So let's take a look how far I can go with my simple items... I was inspired by this a bit more complicated and more expensive project: https://hackaday.io/project/9281-murgen-open-sourc... Here are the parts ...

https://youtu.be/WhDgftYFQ5g Summary This PCB (Printed Circuit Board) resembles the YouTube Play Button award that is given out to creators for reaching certain milestones such as 100,000, 1 million, and 10 million subscribers. When the switch is turned on, the user can scroll through 5 different modes by pressing the button on the top left corner. The first mode leaves all the LED's OFF, the second is silv ...

https://youtu.be/Sg6A_5jPaTo My wife and I recently moved to a new apartment with our cat, Nymeria. This new apartment came with an extra houseguest - a small bird just outside our door. This bird happily chirps all day, which torments our cat who can't find the source of the chirping. I decided to make a chirping toy using a few extra components I had on hand. I'm happy to report that our cat loves it and ...

Relive the fun of early computer game music with an authentic 8-bit chiptune synthesizer, which you can control over MIDI from the comfort of any modern DAW software. This simple circuit uses an Arduino to drive an AY-3-8910 programmable sound generator chip (or one of its many clones) to recreate that 1980's sound. Unlike the many designs that need specialised software to edit music, this looks l ...

Well most of time i get troubled when i need Arduino in some projects where i need few I/O pinsWell thanks to Arduino-Tiny platformArduino program can be burned into the Avr-tiny Series like Attiny 85/45 Arduino-Tiny is an open source set of ATtiny "cores" for the Arduino platform. It provides a core that enables Arduino users to work with the ATtiny84 (84/44/24), ATtiny85 (85/45/25), and ATtiny2313 (4313) ...

Introduction This is a fairly small (51 x 51 mm) board, equipped with a low power Intel Quark D2000 microcontroller, and several sensors (accelerator, temperature, humidity, atmospheric pressure), as well as a mikroBUS compatible header and a Grove compatible connectors, that can be used to connect additional sensors, memory, or radio modules. The board can be used to monitor the environment conditions, and ...

The ADXL203 Module  is high precision, low power, complete dual-axis accelerometers with signal conditioned voltage outputs, all on a single, monolithic IC. The ADXL203 measure acceleration with a full-scale range of ±1.7 g, ±5 g, or ±18 g. The ADXL203 can measure both dynamic acceleration (for example, vibration) and static acceleration (for example, gravity).The typical noise floor is 110 μg/√Hz, allowing ...

Description A smart, programable Fidget Spinner with the following features: * JavaScript programmable * 10-Pixel RGB PoV display (using APA102 LEDs) * Spin count / speed detection using a magnetic latch * Using Nordic Semiconductor nRF52832 chip * Bluetooth Low Energy (BLE) communication with smart phone / computer for controlling the display, reading the spin count and programming * Over-the-air firmware ...

https://youtu.be/_Qog6ofGD5Y Once the purview of strictly military operations, GPS has become a regular part of modern living and in relatively short time! Who wouldn't want want to know when and where they are anywhere on the planet? It's a science fiction dream brought into reality, one now so woven into our lives it seems almost trivial. The demand for precise positional data built into planes, ships, ca ...

DipTrace is a sophisticated schematic and PCB layout software. I had it installed on my computer for over a year but have never really used it. Since I needed a super simple PCB for some 78XX / 79XX type linear regulators, I decided to use this opportunity for my first steps with DipTrace. DipTrace offers different prices for different packages [1]. The cheapest version, DipTrace Starter (300 pins, 2 signal ...

Reading the temperature of your environment is pretty easy right? A quick search suggests the utterly ubiquitous DHT11, which speaks a well documented protocol and has libraries for every conceivable microcontroller and platform. Plug that into your Arduino and boom, temperature (and humidity!) readings. But the simple solution doesn’t hit every need, sometimes things need to get more esoteric. For years we ...
