Very cute, if rather old-school at this point, board. It's cool that you managed to do this using software USB, too! It's both weird and wonderful that they show two out of three pictures with the full-size ("printer style&qu

Great article for someone who mostly hears about the MEGA65 and C65 from the sidelines (8-bit Guy etc). It would have been great with images to illustrate all the various concepts but that is obviously a tall order. Does anyone have maybe a

Yeah, that was what the "kind of" was meant to shadily cover. Thanks for clarifying.

Sure (I was there) but the same can kind of be said about mice and keyboards, too. Ever since USB took off ~30 years ago and basically killed off raw I/O pins on the front of computers, human interface devices have required microcontro

I was first exposed to microcontrollers when I learned about the Microchip 16x84 [1] in the mid-nineties. As a 20-something CS M.Sc student with a software background it was really opening up the world of electronics in a great way. What a

Here I guess BDUF = big design up front. Edit: failed to spell "I" correctly. Ouch.

Yes, sorry should have been SBC for single-board computer. Was outside, fingers cold. Happy new year!

The chip in TFA is definitely described as being a microcontroller (that's the MCU in the title after all). Sure it's 32-bit and 300+ MHz but I don't think it runs SCB-level OSs like Linux. Didn't see any mention of an M

Wow that sounds fantastically optimistic, or pessimistic depending on your point of view I guess. Rewriting that amount of code in ten years sounds very very hard, at least.

I wrote a Linux filemanager very heavily inspired by DOpus way back, it's called "gentoo" [1] but I don't think it has a site online which is silly. It's a bit old, but quite configurable and I believe it's sti

By severely limiting what you could do, it seems. From the Wikipedia [1] page: Programs are restricted to 64 characters in size and normally 9 lines of code, limiting the programs that can be written (users can disable all windows except P

That sounds like a hard hard real-time [1] problem, one that I would be very scared of trying to implement over USB to a PC. Especially if that PC runs a ordinary non-real-time operating system. Sure, USB and a typical desktop-class CPU are

I guess you know the answer, and it has been mentioned several times already: search is "bad" from the seller's point of view, they don't want you to buy what you want. Instead they want you to buy what they want to sell

Mr Higgins is mentioned in the article as being the person who (backed by the EFF, I guess) got them to make the images available so the connection makes sense. I guess that's one use of the paintings that was not possible before, so y

Meta: perhaps this should have the new version number ("10") added to the title. According to Wikipedia [1] release 10 is five days old which would seem to make it news-worthy. I think Cloanto could work a little bit on their webp

Great links, thanks! The first one has an awesome typo (I hope, else they're being a bit evil) with a double negative in the text explaining the instruction: Inactive elements will not not cause a read from Device memory or signal a f

Very interesting and hardcore solutions, adding new instructions to improve data copying in a more "clever" way that just the repeat-prefix seems like an interesting path. There was a silly typo in the very first sentence that thr

Really fun, great introduction to the exciting new features. Which part of the example implemented using `nullptr` instead of `NULL`, which is also from the future, though?

I guess "ETL" in the article stands for "extract, transform, load" [1] which seems to describe a workflow/pipeline concept for importing data into a database. The described company was into "reverse ETL" s

"You shouldn't use gets(), it's dangerous and deprecated". Heh. No, I realize the code is from 1989 and gets() was not on the hitlist by then. What is not so clear is if the first the author wrote after studying the post

Hadn't heard of "mho" for conductivity, is that from when Bourne worked with electronics? :) I would oppose a unit that starts with a prefix symbol (m=milli=0.001) on principle.

Not directly but it seems to be able to generate video out over the MIPI, at least. Not so convenient though, converter chips are probably small and not super hobbyist-friendly (like the one from Analog a siblibg comment dug up).

It allows you to use Linux, which is a sellable bullet point. Might also be useful sometimes, and allow knowledge sharing, increase portability and so on.

Thanks! Apologies if I sounded overly salty/negative, that was not my intention. I don't ski, but obviously skiers also deserve seeing where they are going, it has safety benefits. :)

So, it's a thin layer of gold consisting of all-connected particles, thus forming a conducting layer. Then they sandwich that between layers of titanium oxide for protection, not sure if that will help with mechanical durability. Since

Does it have USB port(s), then? Windows 95 might handle that if patched/updated properly, I think.
