A new display and CTCSS for the Yaesu FT-290R
I purchased a Yaesu FT-290R all mode 2M transceiver from an estate sale recently – it was the last item out the door, because it had a faulty LCD display. The radio worked beautifully, although it was marred…

I have a couple of old paper tapes – I also have an ASR33 teletype, which is more than capable of reading a tape, but making the ASR33 operate correctly is a labor of love which I will…

Or how I (almost) interfaced an Yaesu FT-891 radio to an Icom tuner. I recently decided to replace my Icom IC708G in the car, as it had a weird ALC fault on transmit. It is afterall, a radio…

I extended the relay controller design that I put up recently to do the task of being a watering system. Getting the code to fit into an AtMega328 was a bit tricky, I kept having stack overflow problems…
Read More »An Ethernet Relay Controller
As a recent project, I designed a cool relay controller that uses a state machine to control a set of relay outputs based on a user defined program. The initial task is to operate a set of Christmas…
