Hopefully I'm going to put the finishing touches on the BBC Master 128 tonite. Got the rotary encoder for the embedded gotek now. Let's get this baby running and watch some demos!

@arturo182 It is like that saying, "nothing is easier than gaining weight."

Regarding tasks/work, if only "finishing stuff were as easy as thinking of it."

Firmware v0.4.0 for #PicoGUS is out: github.com/polpo/picogus/relea

The theme behind this release is moar better DMA – many many games that would fall over on it now run pretty great. And the demo Inside by CNCD *finally* runs with DMA sample upload. That one has been my white whale for months now...

.... and done.

No ERC reports mean the schematic is 100% perfect right?

oh... the error count changes depending on which sheet I run ERC on... hm.

Oh good. After annotating 8 of the 9 parts missing annotation, the error count went UP by 43. (I can't find the 9th one.)

I'm going to need much more tea.

Save this screenshot for the next time you think: "wow, this project is really out of control..."

I offer you this piece. I call it: "At least this isn't the state of *your* ERC."

A milestone - KiCanvas's schematic viewer now supports selecting symbols and viewing their information. 🎉

It's kind of funny, since I'd already had this working in the proof of concept (& the version on my blog), but this is a completely re-built viewer. It's much faster, much smoother, and much more robust.

Do you love SCSI and vintage Macs? Well good news!

The NEW and improved BlueSCSI 2.0 has arrived!

Offers faster speeds, delicious new Pico-powered PCBs, and less battery bombs!*

A good Python library and a set of tools for creating, reading, writing, inspecting, and manipulating Intel HEX files. It's handy also for processing the output of CP/M assemblers and compilers.

@north If you watch Bugeja's video, one layer is a serpentine trace. That trace heats the entire board.

The circuit itself is a controller to get a proper reflow profile.

So you manually manage the power on the first one. After that, you have a controller for the following boards.

He's using SnBiAg solder paste, which melts at 138C.

ICMYI, Carl Bugeja created a PCB that reflow solders itself and then self-propagates, RepRap Style!

@trinsec In his demo, I think it was snake. But he says the dual-color 42 LEDs were to match a Connect 4 board ...

This clever PCB business card uses FR4 "fingers" to create a battery holder for the coin cell!
