Nothing puts the fun back into coding like watching your very own creations come to life in the physical world. Luckily, with the current glut of high-tech toys and electronic gadgets on the market, it’s never been easier to experience the thrill of designing your own hardware by modifying what’s already available. A great way […]
Contents Aim To create a device that takes a users input and based upon that input play sounds. I want this ‘synthesiser’ to be simple to play, requiring little or no skill. Therefore, allowing the user to experiment with the sounds they are producing instantly as opposed to learning the technicalities of it first. Research […]
Hello, I have plans to build myself a solar powered wireless Geiger counter using a RH Electronics Arduino IDE Geiger counter connected via a serial connection through a logic level converter to a 3.3V ATmega328P-AU Pro MCU with an ESP8266 serial WiFi tranceiver to send the readings from the Geiger counter to radmon.org.I intend to […]
As mentioned on the Contents page, two different hardware platforms have been successfully used to support Mk2 PV Routers. [Update at 7/3/14: Since writing this article, I have developed a new hardware platform which has been specifically designed for this product. The main board has an integral power supply and RF module, and there is […]
In this tutorial you will learn how to communicate with a computer using a MAX3323 single channel RS-232 driver/receiver and a software serial connection on the Arduino. A general purpose software serial tutorial can be found here. Materials needed: Computer with a terminal program installed (ie. HyperTerminal or RealTerm on the PC, Zterm on Mac) […]
This article describes a simple spectrum analyser for the 2.4 to 2.5 GHz Wi-Fi band. It’s based on the Cypress CYWM6935 Wireless Radio Module. Although the manufacturer doesn’t recommend it for new commercial projects, it is still widely available from eBay suppliers and Farnell here in the UK. The module has 1 MHz channel spacing […]
We have a great thread that contains lots of info on thermal differential controllers here. However, I wanted to start a thread dedicated to my own development of a thermal differential controller that I’ll be using for my attic heat reclamation project. Tonight I setup a simple circuit that tested the operation of the differential […]
I’ve built a number of projects that have interfaced the output of the Simple Bat Detector with a microprocessor. The most recent was the BatLogger II. But I hadn’t come up with an easy way for others to experiment with this idea … until now. My friend, Frank, in Germany, had wanted to make a […]
In this Arduino UNO tutorial, we are going to use a Light Dependent Resistor (LDR) to create a simple childrens bedroom nightlight which turns on automatically when it gets dark and turns off when it gets light. An LDR’s resistance changes depending upon the amount of light hitting the sensor. For the LDR we are […]
I bought a small aquarium (54l) as an impulse buy and I needed some lights for it, so naturally I wanted to use LEDs. I also needed a timer for the lights. I also wanted the lights to fade in and out when they were going on or off as a cool effect. I ordered […]
