Talking of maplin. If anyone on this instance and in the UK wants any RP-crimp SMA plugs or sockets then let me know.
I’ll happily send a few (no charge!) to anyone who needs them. I think reverse polarity is generally used for WiFi gear. I have a bunch of each for RG174 and RG58.
I also have a load of other random connectors, just nothing particularly common, so if you’re looking for something odd then let me know and I’ll see what I have.
Finally got my Pi synced to the PPS pin on the GPS I plugged into it. It's currently indoors with a small ceramic antenna, but works.
Software is gpsd and chrony, hardware is a cheap ublox board with a hirose u.fl connector and a patch antenna, soon to be replaced with a chinese outdoor antenna.
The Pi is a model b, configured to use the standard UART (ttyS0) not the better one (ttyACM0), but that might need to change.
I think it'll be cool to add a little display with position/clock info.
Had a lot of fun on the club’s fox hunt last night. It was my first, so I basically went to see how it worked. My team failed (mostly due to a lack of decent gear I reckon) but I will know what to do next time! First on the list is getting my tape measure antenna working.
Looking forward to it!
Spent a while yesterday receiving SSTV images on 20m (14.230 MHz), some pretty scary and really interesting.
I don't think anyone would deny that it's a pretty weird way to communicate, super fun though. Next I need to work out how to TX with qsstv (but first, family stuff)!
Just my shiny new µArt (https://www.crowdsupply.com/pylo/muart) to flash some custom firmware on a couple of cheap Sonoff wifi switches (https://www.banggood.com/DIY-Wi-Fi-Wireless-Switch-For-Smart-Home-With-ABS-Shell-p-1019971.html). They now work with Alexa without some dodgy third party cloud service.
It's funny that the USB UART I used cost considerably more than the devices!
Didn’t manage to do everything I wanted to this weekend, but I did manage to build my £3 crystal tester, and this SOTABEAMS end fed tuner, plus wire it up ready for a test a tune on 40m.
I also managed to make up some test resistors to calibrate my cheap SARK 100 antenna analyser clone.
Actually I’m pretty happy with that list of stuff!🤔
