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/

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.

Does anyone know if it is normal for a C64 to produce sharp notes? This should be A4 @ 440 Hz, but it is high. (All the notes are sharp.)

This is generated with an ArmSID and Qwertuoso.

Here are some of the things I picked up last weekend at Hamvention ... These will become parts of future projects. (Really! ... probably.)

Also, this little guy was on a table near the entrance.

A few pictures from CoCo Fest 2023 in Carol Stream, IL. (Very close to Chicago)

Check out this Pi Pico development board an e14 community made (and then sent me!)

It has some nice features. The board files are available to get your own.

Anyone check out these new standalone "Active EMI Filters" from TI yet? I find their description... intriguing.
