The Dragon Amateur Radio Club has many members with a hugely diverse skillset. John is indeed another of these members who has a wide range of interests and hobbies other than Amateur Radio.
John is a passionate walker and living in North Wales offers him some of the best walks in the UK ranging from coastal paths to mountain trails. The Anglesey Coastal Path provides stunning sea views and diverse landscapes, while the Mawddach Trail offers a beautiful, traffic-free route along the estuary. For mountain adventures, the Snowdon Horseshoe and the Watkin Path are popular, though challenging.
Another interest that John has recently discovered is laser and wood cutting which has led him to join his local craft shop. Unlike a traditional Carbon Dioxide (CO2) laserJohn uses a powerful LED laser, or diode laser.
These work by using a semiconductor to convert electrical current into a focused beam of light. Unlike a regular LED, which emits light through spontaneous emission, a laser diode uses stimulated emission to produce a highly coherent, monochromatic (single wavelength) beam. This process involves an optical cavity and mirrors to amplify the light, creating a powerful, narrow beam which due to its intensity can easily burn wood. Adjusting the power of the laser allows the user to either lightly engrave the material surface or indeed cut right through it!
John has made a range of gift items for people all over the country since joining the craft shop ranging from clocks, to amazingly detailed jewellery boxes.
