My dual base amplifier is built to match remote wideband loops to a coherent two-channel receiver. Implemented with wideband FET op amps, performance is great. Read more
My surface mount toner transfer experiments led me to move from using magazine pages to heavier photo paper stock to get better results. Take a look! Read more
KiCAD PCB design is something every electronics maker should learn and use for their printed circuit boards. It does pretty much everything and it’s free. Read more
Surface mount PCB artwork requires you to print designs smaller than a grain of rice. Is this even possible with my home laser printer? Read more
There are lots of designs for making a circuit board drill press for PCB fabrication. I thought I would try one. Read more
Making a loop controller PCB is pretty straightforward.
My 3D printer now does auto-leveling using a proximity sensor and an external control board. This DIY PCB article describes completion of printed circuit board used in this project.
It’s amazing that after so many years with radio and electronics hobbies, I had never created a DIY PCB scratch. Oh, sure, I have used printed circuit boards made by others many times. These were either purchased commercially, or fabricated to my design. But it was time to make my own. So, here goes.
