Various ramblings – Electronics, Radio, 3D Printing & CNC
With the case finished, there was only one thing left to do… Jam the radio in the case and make it work! The digital dial kit and main board are secured to the case using brass stand offs (used for securing motherboards in PC cases), once cleaned up they solder rather nicely to the PCB cladding. The lid is secured...
My relatively new BK Precision multimeter got rained on, a leak in the roof on the deck soaked the table I was working on when some heavy overnight rain decided to come bucketing down. To say it was rained on is an understatement really, it must have been placed perfectly under a torrent of water that jammed more water into...
Being my first transceiver, I really wanted to make it my own (well, as much as I could with a kit…). I had seen many radios built into cases made from FR4 fibreglass PCB material, and thought I might have a go at doing my own. Quite a simple process but it would have been much easier if I had...
To align my SW-40 transceiver I needed to use a dummy load, something I didn’t yet have. The dummy load I bodged together in a hurry was 2 x 0.5 watt 100 ohm resistors in parallel on a BNC chasis connector. It worked, but got warm enough to discolour the resistors enough to make reading the values tricky. I had...
My first transceiver kit, a nice little radio with great instructions and is easy to build. I built this board over 2 nights, about 4-5 hours in total. While researching and ordering this kit I was still in the process of getting my foundation license, and not long after getting the kit in the mail I stumbled onto a small...
