      Attached: 2 images A gentleman named Paul Khoury approached me about getting a retro computer he'd acquired up and running. The computer is a Sun SPARCstation UPN (1997), a prototype for a super small desktop computer that preceded the Mac mini by about 6-7 years. Only about 20 were ever made. I was the designer on the project and had poured my soul into it, so I was proud to help him get it running. I dug out the schematics from storage and gave any advice I could remember and he got it powered on in a few days.

    Very excited to have a paper published in DUBUS. I’ve been reading this journal for about a decade and never imagined when I started that I’d be published there. The journal is also translated into German (or English) by the editors, as it’s a dual language publication.

    “Don’t ask me how I did it I just did it and it was hard”. J/K, I will document this properly soon and it’s much simpler and than it looks.

    @Stormgren @kb6nu yep, check beacons, and wspr, dxmaps etc. seems quiet now. Local VHF groups can be helpful when setting up. The antenna should rx ok-ish on 10m, too.

    It feels like cheating to use these pre-cut wire links for soldering (vs. push-in breadboard), but I’m over making these by hand. #amateurradio #hamradio #electronics

    @kelvin0mql @vees you need to visit the Australian outback, Milky Way easily visible (much better vantage point) and you can also see the Magellanic Clouds, with the naked eye.

    @jarkko I’ve never played with FPGAs, need to fix that at some point. This is possibly very relevant to RF digital, lots of amateurs now using s/w modems via usb sound, but performance is not optimal at high bandwidths. They will struggle to utilise the full potential of the recent FCC changes in the US to increase the data rates allowed on HF.

    Prototyping a monitor circuit for GaN RF power amplifier devices. This is indicating drain current and heat sink temperature, and can be expanded to other measurements as needed. What started as a ‘simple’ project became an entire side quest. This uses an Arduino Pro Mini, an INA169 current sensor, and a thermistor. Could be done more simply with a PIC but this is what I had. The cheap OLED display self destructed not long after this photo, as I fed it 12v instead of Vcc.
