“No plan survives the contact with the enemy. ” Szymon and Jakub talk about the challenges of building a non-invasive blood pressure measurement device and then porting it to Zephyr RTOS at #hackadaysupercon

Learning about $5 MCUs for wireless hacking from @AlexLynd #hackadaysupercon with his various WiFi projects (mostly ESP based.)

At @hackadaysupercon, @pluralistic kicks off with a talk about How the Internet *used* to be good.

Thur Nov 2 Stream: Let's finish the Apple II+ Schematic in KiCad! (And then I'm headed to Supercon!)

@mmu_man Right? Just need to autoroute and call it a day.

This looks fun...

Thur 10/19: Let's work on the Apple II+ KiCad Schematic live! (Right now!). https://youtube.com/live/_R6WSO2lKi0?

This schematic is part of the Bit Preserve Github repo. That's where people use KiCad to redraw schematics for vintage computers.

From jlink commander: Savebin <file>, 0x10000000, <size>.

For future me, the next time I need it.

Anyone know how I can use a segger jlink mini to dump the EEPROM connected to an RP2040?

I want to make a backup of the existing binary before I flash it with a new one.

@wa7iut One thing I think Rigol nailed is the keypad.

Every other power supply I use is counter intuitive compared to it.

I love not having to think "voltage" or "current" first. I type in the number, then the unit. Because my brain doesn't say "Volts 5" or "Amps. milli, 250"

@LabSpokane @adistuder Yup. I made it because A) I wanted one. and B) I wanted to practice making a PCB you break apart and solder together.

Also, I couldn't find any right-angle board-mount Banana plugs.

@adistuder I want to add that and a reverse circuit. It’s a little too easy to plug it in backward!

It’s a silly design, but I love my compact Banana-to-USB adapter.

Live Stream: Cleaning up the Apple II+ schematic in KiCad. Lots of "off-grid" errors to tackle. https://www.youtube.com/watch?v=4Btk6DANLzY

@joeycastillo How many times did you hit the non-existent undo button?

Let's work on some Apple II schematics, in KiCad, live!

@mmu_man This is why I am a hardware person. :)

@mmu_man It’s still better than a bitmap. At least things are properly searchable.
