Re: Amazon Basics Laminator design

Is the DPDT switch "center off", by chance?

If that's the case, then the two "other" positions represent operation at 115C and 125C ("operation" implying the motor is running to pull the material...

Re: Looking for advice in tutoring a child in basic electronics

My first "programming" experience with computers was an ASR33 via a 300 baud modem to a remotely located minicomputer (I'd played games -- Empire (https://en.wikipedia.org/wiki/Empire_(PLATO)) -- on...

Re: Looking for advice in tutoring a child in basic electronics

I think a big part of learning -- and "holding interest" -- is having activities that AREN'T "color by numbers". If a kid just has to complete a set of predefined steps to finish a project, it will...

Re: speaking of car battery chargers...

Depends on the design of the turbocharger.

A friend makes them (after-market) in his tool-and-die shop gearing up off the crankshaft so he can get it up to speed at relatively low RPMs (you have...

Re: speaking of car battery chargers...

For some years, now, there has been a push to move to 48V systems in cars -- mainly to cut down on wire gauge (without also needing dramatically costlier semiconductors). Imagine the turbocharger...

Re: Looking for advice in tutoring a child in basic electronics

It was just the first hit that turned up in my search. You (he) might ask the local schools if they have or know of any such programs nearby. Or, if they might want to START one.



No idea. ...

Re: Looking for advice in tutoring a child in basic electronics

My folks were "high school educated" -- at best (?) When I (as a toddler/young kid) asked questions that were beyond their comprehension, they bought me "stuff" to tinker with -- dry cells, wire,...

Re: Looking for advice in tutoring a child in basic electronics

IMO, don't focus on "technology" as much as fostering a creative/inquisitive mind. There, you want to focus on exposure to new/different ideas, possibilities, etc. and let his particular interests...

Re: Oscilloscope Advice....

I used to drag one around on aircraft as I was traveling (would never trust it in "checked luggage"). For that era, it was *highly* portable. In a pinch, I wouldn't mind traveling with it -- though...

Re: What TRULY Renders an Operating System Obsolete?

Demand has nothing to do with it. When something is SCARCE, then demand appears higher. How many LPs are actually *pressed* each year? Contrast with CDs? Digital downloads?

Re: A Colossal HDD Failure

Any sort of "large data transfer" can almost always be spread out over time (the exception being HUGE torrents that aren't seeded for long periods of time). So, just choose that "time" to be one...

Re: A Colossal HDD Failure

You've completely missed the point.

Are you *using* that bandwidth? Will they sell you 10% of that bandwidth for 10% of the price? Do you even need that 10%?

Would you buy a gross of donuts...

Re: A Colossal HDD Failure

It looks more like you were conned! What do you use that bandwidth for? You can fill a TB drive in ~130 minutes. THEN what?? :whistle:

Re: best cheap/free scores 1.1

Time to add another shelf to the SAN...

Re: What TRULY Renders an Operating System Obsolete?

Obsolete can mean many things. By your own (above) definition, don't digital media formats "serve the purpose vastly better" than vinyl? When was the last time you heard a "skip" in an MP3? Or,...

Re: Win XP Pro

Best to boot the original, keeping the clone as a copy to be used to restore the original -- in case the software has been "locked" to the drive ID (to discourage counterfeiters -- esp if the...

Re: What TRULY Renders an Operating System Obsolete?

I use a rescued ASUS Eee PC 1000 with NetBSD 8.1 to, periodically, download "packages" for my *BSD boxen. Internal SSDs (I think there is one for the "system" and another for "scratch") are way too...

Re: What TRULY Renders an Operating System Obsolete?

It's not just OOPS that leads to bloat. Much of it comes from trying to leverage existing "packages" to provide some feature or capability. These invariably have lots of extra cruft to cover uses...

Re: Win XP Pro

Not necessarily. It's whatever the developer chose to use as their base. E.g., I have a DSO that has Win95 in it (to run its GUI)... do you recall a "Win 95 EMBEDDED" product being offered?

Re: What TRULY Renders an Operating System Obsolete?

Sure. OTOH, I was running X under SysV on a 2MB OPUS coprocessor with a 40MB disk in the mid 80's (the PC acting as a fancy "I/O controller" to manage the disk and VGA display)

Yes, but my first BSD distro was only a hundred megabytes. And, that included the sources and tools to rebuild the complete system!
