Speed isn't the issue, it's latency. Some people don't mind latency. Some people will know just how to fix latency problems with software emulators, their host platforms, and modern hardware and controllers. I'm not i

The irony of course is that the keyboard is perhaps the worst thing about the Atari ST and much of the charm in these old systems is the crisp real-time response of their simple hardware and software - which you won't get in a software

Thanks. Of course. I'm flattered.

Nice job. Effective capacity also drops with load for many batteries, and there can be subtleties. Read all the data sheets and applications manuals from your suppliers. Even very good firmware engineers can need reminders that everything

The laws are well understood, but not universally, even among credentialed experts, either. And implications of them remain to be discovered. And on top of that, their predictive power is limited.

Amplifier tubes have only a little overlap, if any, with the tubes you will find in a typical AM radio like the one described. Maybe the rectifier or the output tube. There is still (!) plenty of old stock of radio and television tubes out

Nice. In the US, I definitely remember seeing kits (perhaps loosely defined) of surplus keyboards and instructions for adapting them to the ZX81. A friend's dad who had built his ZX81 from a kit added a keyboard that way. Just littl

Simulink is of course the modern replacement for an analog computer and does a lot more. For open source there is Scilab xcos and underneath it OpenModelica. It would be crude and inefficient but you also could use spice and rig up op amps

Carver Mead tried back in the eighties. There’s a book - and Synaptics.

A really good analog FM signal can sound very good on a very good receiver but I am a picky listener and I would not characterize HD FM that way. I don’t hear any difference on my car stereo and I hear very little difference on my old Sony

There are fast segment based fill algorithms from the seventies or very early eighties in the literature and reprinted in the first volume of Graphics Gems. They work very well and do not require the call stack or amount of computation of

I think those numbers are Taiwan dollars, and "m" is for billions i.e. milliards. So closer to $300 USD per employee per month. For fun, compare to McDonald's.

Automation doesn't guarantee quality, and it is hard to do at a high quality level, at scale, also.

If Wistron was having quality problems, as has been rumored about iPhone production in India [1], this could have been the sort of deal where both sides lost. [1] https://www.theapplepost.com/2023/02/26/apple-

I'm not a career optical engineer but numerical optics is a general term for computer modeling of optics (i.e. by number-crunching), like numerical anything else. In practice that means prysm can simulate wave phenomena and aspects li

We'll sure find out, because there's no way to keep people from it.

It's hard to capture for a modern audience. It's not just, say, the tutorial books that were packed in with the home computers (the curious might try one of the ones for the Apple II, Atari 8-bits, or Commodore 64 with an emulato

There was a president after that who was in a partnership that bought an S&L in the eighties and gave itself bad loans, but it was made out to be so complicated that no one could ever understand it. Everyone else involved in the partne

The fcc used to require certification of commercially produced superregens for this reason. Neither of these radios appear to be superregens though.

I don’t see a schematic, but I find the 10.4 MHz oscillator confusing. A regenerative receiver with an LO is like a motorcycle with four-wheel-drive.

Sure, desktop CRUD apps have been obsolete for 25 years, but I meant a desktop application in tk. Also, an example application like Northwinds, not a framework. Not exactly what I’m thinking either, but look at how concise pgaccess (for po

I’ve said it before, but I’d love to see a best-practices CRUD app done in tcl, tk, and SQLite along the lines of the north winds thing from Microsoft. The SQLite interface in tcl is a thing of beauty to rival tk.

>Honestly, the datasheets are usually just wrong. The writer is an intern and the material is cargo-cult copy-pasted. If it works it's by accident, or because it wasn't critical in the first place. Read the datasheet, understan

Without answering how much conductivity you had, how it caused the circuit to fail, what part of your circuit failed, and in what way, you haven't really narrowed it down to the flux, even if cleaning helped. There are a number of mor

My conjecture: there is ambient RF noise on key fob's frequency (most likely 315MHz), which is causing the key fob receiver circuit to remain active and process any signals that it receives, rather than going to sleep and periodically

It's fun, too! Even through-hole, where you really don't need a 'scope, is oddly satisfying when you can see every detail.
