Coupling a Magnetron to Coaxial Cable

Before we begin I’ll start with the obvious warning: Working around microwave radiation is potentially hazardous and could result in electric shock, burns or death and may cause interference issues with nearby users of WiFi and other services on 2.4 GHz which could potentially be illegal in some jurisdictions. I’m sure I don’t have to […]

Using Shift Registers with the Arduino

Below you will see the first circuit based on a 74HC595N shift register. It controls eight green LEDs which sweep back and forth in sequence. This would normally require eight outputs from the arduino but with the 74HC595N, only requires three. Digital pin two provides data to the shift register, pin three provides the latching […]

The Real Basic Radio Transmitter

Personally this is as basic as they come and have a range of 10 miles or more. It won’t do voice but will do Morse code and can be constructed from around $1.50 or less in parts. You will need.. * 1 crystal resonator. I used a 3.579545 MHz crystal which will work in the […]

Radio Repair, Maintainence and Modifications

Well the shortwave receiver of mine has been causing problems with me lately among other things. Firstly an intro to how it works. The radio receiver is a Wadley Loop design which differs from the Superheterodyne type receiver used in most radio receivers. They work by mixing the received signal with an oscillator to create […]

Homebrew Phase Converter

In this guide I will show you a simple way of producing 3 phase electricity from a single phase supply. Firstly, Only attempt this if you know exactly what you are doing. Daktologist Industries is not responsible if you somehow manage to electrocute yourself, damage your equipment or burn down your house/workshop or otherwise fuck […]

A Basic Introduction to Electronics

Electricity. It’s all around us, from our appliances to our vehicles to lightning and static. In this guide I will go into the subject of electronics. Firstly what is electronics and how does it differ from electricity in general?. Well electronics deals with using electricity to perform complex tasks like amplifying sound, measurement and many […]
