Some hours later, got it working. Using the PCB as the temperature sensor, with a k-type thermocouple.

Calibrating the PID controller of a DIY reflow hot plate. Mistakes were made.

The lack of threading here is diabolical.

@ftg @azonenberg @dlharmon I general, I cheat by not trying to use coax above 24 GHz, but I really should give it a go at 47 GHz one day. I'm thinking in terms of using spatial combiners though, all in waveguide, right from the device outputs. The detailed engineering needed to get excellent matches across coax to CPWG or microstrip is Officially Hard.

@g4dbn @DosFox I feel this. If AI & robots can't fix this, then what use are they?

Hi folks, I've just posted an edited version of one of the presentations I gave remotely at Microwave Update 2024 Vancouver. It's about some of the techniques I've been experimenting with for manufacturing antennas and feeds now I have a tame 5000-pound killer robot in my workshop, otherwise known as a SYIL X5 CNC mill.

@daniel thanks! Wondering if this will also work as a Teams background

I visited ESA’s antenna laboratory so now you get new wallpapers (for free even!)

PROGRAMMING TIP
avoid repeating the same 4 lines of code twice by writing 270 lines of beautiful, abstract, generic code

@g4dbn question on surface RMS for reflectors & horns: do you know if EDM could work for this?

At Microwave Update in BC (https://www.microwaveupdate.org), one of the vendors had a 170 GHz spectrum analyzer. How is it possible in a device this size? #hamradio #microwave #amateuradio
