Thur 1/25 Stream: Checking out KiCad 8 RC2 by drawing an extender card for the Mega IIe:
@48kRAM It might be Monday for me. I checked this morning, and the package was at the local DHL hub. I just got the out-for-delivery notification!
But I probably won't be able to get it until Tomorrow. :(
@48kRAM Just wait until you get to the 3rd flash drive and find out it is faulty.
@48kRAM what an old timer. This one remembers when computers had fans. lol.

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
@48kRAM Is it Monday yet?
Here are some lessons I learned when trying to turn on a recent RP2040-based tool I designed.
@mmu_man Years ago when they started charging for downloads, I stopped using and recommending it.
Do people still use it?!
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?
@retrorewind Me too! That one replaced a 4-bay that had a failed slot.
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/
@polpo I think that Netscape icon is my favorite.
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)
