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

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/

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:

Feel pretty pleased with myself, I just built my first home-designed PCB and it worked :alex_grin:

It’s the small bidirectional amplifier described here: http://w7zoi.net/bidirectional_matched_amplifier.pdf and built by w2aew here https://www.youtube.com/watch?v=7TtKE39TWpI

I made a couple of footprint mistakes but didn’t need any bodge wires! I spent ages messing with KiCad but learned a lot, and have a few ideas for changes. I don’t really have a project in mind, but wanted to build something simple I could use to learn.

A small dark blue printed circuit board resting on an LCD display. The board has SMA connectors on the top left and right and three wires on the left. On the board are two almost identical circuits made of 0603 surface mount components and SOT 23 transistors.
