@tnt:@42Sec's work on porting gr-osmosdr's#osmocom_fft to Qt and python 3 is now in the gr3.8 branch of http://git.osmocom.org/gr-osmosdr/log/?h=gr3.8 … Please test and report. If no blockers are found, this branch will become the new master and first tagged release with 3.8 support.pic.twitter.com/SqCd5b1oE9

Smoke test passes, and a quick test with the GreatFET puts it into RX mode successfully

We won't speak about try #2, but I'm very happy with try #3 aside from maybe a bit too much paste applied? I don't think I was pressing hard enough. I might have trouble with that QFN.pic.twitter.com/u4JPSyJ8SZ

First go was surprisingly good, but I think I smudged it a little on release. Should still work fine!pic.twitter.com/6o571WVT4z

All ready for paste application. I've not done this in a _while_ so this might take some tries.pic.twitter.com/J6hFE374Qv

Time to do some assembly! First job is to depanel these stencils...pic.twitter.com/jGm3Qbj8Bq

and.. there's the problem - some of the traces are completely blown out. Someone put way too much power into this at some point

I managed to carefully press the PCB out of its housing. Now we can see what's going on properly! It looks like a Pi-attenuator, with a neat grid structure to allow for trimming resistor values after construction.pic.twitter.com/T2sf6G5D4w

The actual attenuator - it looks like a ceramic PCB with printed resistors, plated ends to make contact with the spring-pins, and pressed into this tube to hold it in place.pic.twitter.com/0CwwuLzwxI

Thermocouple interface boards arrived from
@oshpark so I can finally fix up@edinhacklab's T962A reflow oven!pic.twitter.com/0rZELz2PTj

Took a punt on this reference attenuator on ebay, to go with some cheap power sensors I got recently, but it seems just a *little bit* out of spec. The seller was nice about it, so it's teardown time once the refund clears!pic.twitter.com/VeG6LL8isY

yay, PCBs. I worked with
@kbeckmann on a new revision of his SX1257 PMODs - I'm looking forward to getting these built up and trying them out! Also I had some space on the stencil, so I panelised a couple of other projects - I wonder whether anyone can spot what they are?pic.twitter.com/6pEjEgusRb

I used
@Claude1079's great technique of programming a UART on every pin that transmits the pin name, and started reverse-engineering the pin-out here: https://github.com/miek/chubby75/blob/5a-75b-v7_pinout/5a-75b/hardware_V7.0.md …pic.twitter.com/Bi0aEtadpY
