Thur 2/1: Redrawing the TRS-80 MC-10 Schematic in KiCad 8 RC2!
https://youtube.com/live/11hBRgYjpRU
We repaired one of these on-stream a couple of years ago. Now it is time to add its schematic to the Bit Preserve archive.

I've decorated three denim jackets with LEDs to bring as an installation for the CETI institute in the #portlandwinterlightsfestival . The CETI installations will be displayed in an abandoned GAP storefront, so this project feels particularly appropriate. Just got the basic animation working for the rain cloud jacket, and hope to find time to enhance it.
It's the one email "newsletter" people actually want to receive.
If you're hosting a reoccurring event, please set up an email list for future events!
I always find out about small meetups two weeks after the date. And so few have a way to get notified about the next one.
And no, having a Facebook group doesn't count. *eyeroll*

i'm really proud of this compass project i just published: https://learn.adafruit.com/qualia-s3-compass
it's coded in #circuitpython and i put a lot of work into it to make sure it was functioning accurately while also looking nice with this round display. this required a lot of math and displayio graphics tricks that will hopefully be a helpful example for folks
Here are some lessons I learned when trying to turn on a recent RP2040-based tool I designed.
Thur 1/11 Stream: Let's Finish Re-Drawing the Apple IIe Switch-Mode Power Supply Schematic in KiCad
I have a friend who would like to transfer some memories off of MiniDV tapes. Does anyone have a deck/camcorder I could borrow or be willing to transfer the tapes?
Doing end-of-year photo album clean-up. I came across this picture in a forgotten 2015 folder.
At one point, this was my entire retro-computing collection.

The package is unusual: the die is mounted on a flat ceramic substrate with a ceramic cap glued on. We heated the package to soften the glue. https://twitter.com/TubeTimeUS poked the cap with an X-Acto knife, but instead of sliding off, the cap violently flew off with a loud "pow"! 4/9

#PicoGUS 2.0 is restocked on Tindie! The last restock lasted 2.5 hours, here's hoping this one lasts longer. https://www.tindie.com/products/polpo/picogus-sound-card-emulator-for-isa-retro-pcs/
Thur 12/14: Is this live stream when we finally finish the Apple II+ schematic in KiCad? There's only ONE way to find out... https://youtube.com/live/vYXDW7x8n9k

After last month's release of #PicoGUS 2.0, I've backported a lot of the improvements to the more DIY friendly original 1.x hardware line, and I've just released those as PicoGUS hardware v1.2. Major changes:
- Better reset stability
- Option for integrated DAC (instead of the sometimes flaky purple DAC module)
- Better fit in ISA slots
- Jumper to apply power to USB port so you can use joysticks (you still need an OTG adapter)
