Here are the toots from my Mastodon account. If you’re into ham radio and technology this is a great inclusive server with an awesome mascot called Alex.

It's Alex! A soft brown mastodon holding a handheld radio in their right hand and carrying a blue bag over their shoulder

📢 WSJT-X 2.5.3 was just released with a new feature for ARRL VHF contents: https://sourceforge.net/p/wsjt/mailman/message/37398008/

I was sad to read that Bill G4WJS passed away recently. I had never spoken with him but was always impressed by his patience and breadth of knowledge.

Only Win64 packages have been released so far, but URLs are the same as always:

Unsure why my 📢 emoji didn’twork!

I managed to get one of the first batch of QDX transceivers from QRP labs, and I just plugged it in for the first time. It needs some tweaks but works!

There are some odd design decisions (9V power and USB type B) but it’s cool and tiny.

A QDX in its enclosure. It’s a small black box 7x9x2.5cm in size with an LED on the front left and connectors on the back (not shown here)

A constructed QDX board with connectors on the right and various components visible, including several inductors.

A QDX circuit in an enclosure with the top panel off. There are connectors on the right and several visible components like coils and transistors.

I just discovered some morse keycaps https://prototypist.net/collections/in-stock-keycaps/products/in-stock-infinikey-morse

The “operator” kit’s caps only have morse on, which is interesting :alex_grin:

I find these development update posts really interesting https://blog.flipperzero.one/november-update/

It’s great to get a view into how real problems are solved. I’ve seen the same sort of thing on CrowdSupply 👌

I hacked a Toaster Oven into a PCB reflow machine.

Basically, I just added a cheap PID controller and a thermocouple, and it was a fun and fairly quick project!

I wrote about it here: https://hackerific.net/2021/11/13/pcb-toaster/

#electronics

A modified toaster oven. There’s a controller on the right where the dials would be. It has two temperature readouts. Inside is a small PCB. There’s a metal wire going through the door.

I managed to use the ST-LINK clone I ordered (immediately prior to ordering a J-LINK Edu Mini) to program a Blackpill board with the arduino blink example. Luckily it’s not possible to have too many ways to program chips.

There are so many cool projects on mastodon.radio at the moment. 👌 inspirational stuff!

Today I spent a while fighting with a “black pill” STM32 board, which must be a clone. I can’t get the thing in DFU mode and it has a weird HID bootloader and USB IDs: 0483:572A [WeAct Studio WeAct Studio HID Bootloader], but everything expects 1209:BEBA. 😕

I have now given up and ordered an ST-LINK programmer (very cheap, so also a clone :alex_grin:) so hopefully I’ll have more luck with that!

I also didn’t know what which isn’t POSIX. Interesting article from LWN: https://lobste.rs/s/vbrl9x/debian_s_which_hunt

My friend and colleague Paul was on the FLOSS podcast: https://twit.tv/shows/floss-weekly/episodes/653?autostart=false I’ve not watched yet due to lots of power cuts and being busy but it’s probably interesting :alex_laugh:
