“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!)

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.

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

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

Live on YT working on an Apple IIe Schematic in KiCad... come say hi: https://www.youtube.com/watch?v=W5LZrmN_rEA

Early in my career, a technical mentor revealed two myths about the Nyquist theorem. I cover them both in this video.

At Hackaday's Supercon 2023, I'll be talking about that little Apple II project I spent over 3 years working on... I'm so stoked that I am smiling in Double-HiRes.

Made a quick badge and used OSH Park's After Dark. It came out great.

Next revision will have a SMD prototyping area on the back. And I'm going to change up the front layers. (Like, make the label area copper.)

@joeycastillo walked through how Sensor Watch maximizes the perphials on a SAM L22 to eliminate the need for external ICs. (Also, TIL about the configurable logic unit—I can’t wait to play with those.) @crowdsupply #teardown2023 https://www.oddlyspecificobjects.com/products/sensorwatch/

“Go do it … [chip design] is no longer an enigma.” — Mohammad MK, eFabless Cofounder encourages everyone to consider designing their own chip at @crowd_supply #Teardown2023

And @esden also shared his “poor PnP life choice” of buying a Hanwah PnP to help make Glasgow happen: https://www.crowdsupply.com/1bitsquared/glasgow

Attempting to talk us out of a Pick-and-Place machine, Joe (@securelyfitz) shows a successful fail of the PnP Badge at @crowdsupply #teardown2023

Here’s the main menu of the web interface. It’s not public yet, but you’ll get access if you buy a uSDR. ;)

Andrew demonstrated uSDR and its associated web interface at ⁦‪@crowdsupply‬⁩ #Teardown2023. It’s a m.2 form factor SDR. The web interface is very impressive. Check out its funding campaign: https://www.crowdsupply.com/wavelet-lab/usdr

At @crowdsupply #teardown2023, @aleksorsist updated everyone on ThunderScope. It’s a high-speed scope that strreams samples over USB-C/Gen3/2.2/Thunderbolt/WhateverItIsCalledToday. Great progress and fantastic presentation.
