June 2018 Update

Well as much as I intended to do at least one article each month, Uni yet again has gotten in the way. To be honest I am having second thoughts about university and have been for months. Following an incident at uni recently I will have a solid answer in a few days as to […]

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.

These satellites happen to transmit images back to earth in the VHF band at ~137 MHz which with a cheap TV dongle can be received at home relatively easily. Personally I have never had much luck up until now and with […]
