The light works. The gravity works. Anything else we have to take our chances with.

I'm totally not counting turns, just playing. note the trick of sitting the spool of wire on end so there is no yanking it as it feeds onto the bobbin! I didn't make the wire guide yet, there is a lot to do...

Did I already mention that those USB Wi-Fi adapters are elephant shit? My guess is that they overheat because their antenna is poorly designed, causing a large portion of the transmitter's energy to be reflected back; this triggers the protection mechanism, cutting off t

It really frustrates me that I can't use the built-in wireless on BSD, because I know that, in most cases, those USB wireless adapters are absolute elephant shit. This particular unit heats up to over 60 degrees Celsius. That鈥檚 hotter than the processor itself.

If the plastic were something like PLA, it would have already softened. And I think there鈥檚 a smell of burning, too.

The firing mechanic is finally done! 馃敟馃П It introduced a bunch of entirely new concepts (fueled crafting recipies, crafting in batches, crafting that requires time to be completed), so I've been refactoring a ton of code lately 馃槄 #gamedev #indiedev #indiegames

And here is what happens when my theories don't pan out: the DFF lacking a clock signal simply halts the entire process. Oh well, time to come up with some other hypotheses. It鈥檒l work eventually, but I鈥檓 already nominating the #TangConsole60k as the most convoluted, twisted

The refinement involves testing one specific "spine"鈥擲PINE27. It differs radically from the other 30 spines because its switching cell falls within a non-existent, empty area. In theory, I imagine it鈥檚 combined with the adjacent cell, but it鈥檚 not straightforward due to

overlapping wire numbers, so I need to verify how it actually works :)

Excellent! 15 DFFs scattered across different clock quadrants are up and running. One LED is dedicated to the "ticks" :) This example will be included in *apicula* once I finish refining it. #fpga#apicula

When #apicula generates a version that works on actual hardware, while the vendor IDE produces a non-working version from the same source code, it becomes clear that I must be dreaming. I think I'll turn my attention to #netbsd on some Pi (not Raspberry :) ) for now.

Due to the complex clock routing structure in TangConsole60k, I am creating a specific example using 16 D-type flip-flops (DFFs) distributed across independent sections of the chip So far, 10 flip-flops are being used: those in the bottom and those in the right section of the top

"Hmm, this is using a whole 6 kilobytes - that won't do; I'll try to shrink it." Working within very tight memory constraints isn't exactly unfamiliar to me, but it is something I'd somewhat forgotten about. And it's actually quite fun. :) #micropython

This isn't just any blinking LED, this LED is blinking under timer interrupts! so the main loop can do other things...

Gee! I finally found that missing wire :) #TangConsole60k has learned to use its clock. 馃槣 Adjustments: all the design's flip-flops are neatly placed in the bottom half of the chip, since I have no idea how to handle the clock in the top half.馃槈 #fpga#apicula

And once again, television fails to capture the delight of watching a squirrel trying to predict the weather.
