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.

Replaced spinning rust platters with @BlueSCSI.

And now I can get to important work.

(This is not the Macintosh with the bombed logic board.)

Remove. Your. Batteries.

Not what I expected to see when I opened up an Apple IIgs with a note saying: "Failed CPU test."

Is this what you take when you get a headache while debugging an issue with an oscilloscope?

My first attempt at building a right-angle Banana-to-USB adapter. Also, first time I've tried to solder two PCBs together. (That I designed.)

Needs some tweaks though.

Check out lcamtuf's latest 8-bit handheld game: Sir Box-a-lot.

It's Sokoban running on an AVR128DA with an RGB OLED screen.

He's also done some other "handheld" games in the past.

Incredible work.

Sometimes your code gets kinda hangy... this is going to be my new while(1);

From the Apple IIc firmware listing:

Friday 2/24 Stream: More work on the Apple IIc Schematic in KiCad! Now on Twitch and YouTube (again). https://baldengineer.com/live

Sega's Gear Gear (VA1) is now available in the Bit Preserve Repo.

And it's a KiCad 7 schematic!

So. Um. Can anyone explain this combo?
