i bought a charger / inverter. they have large charger built in and some have a power saver option which monitors for use over .5 amp to reduce the drain. it is the monster UPS system.

Thank you for explaining the technical stuff - I knew I was confronting a bunch of baloney when I was comparing space heaters. I finally went with a combo if an oil filled and a medium ceramic tower to heat my unconventionally insulated 16' x 16' treehouse I live in. It got down to 6 degrees last winter and 2 space heaters kept it warm - the several I brought home and compared all provided the same level of warming to my senses regardless of grandiose claims on the box. The choices are between noise, profit, and safety, not heat output. Heat output IS all the same.

as always I love your videos. I think you are minimizing the effect the adult video and budget movie studio (art house, B-horror, etc) industry had on the early home player market. With non-tape formats, there is always a significant investment in "printing" a disk. The disk production facilities are in the hands of large corporations and the costs per title are high (so they expect high production numbers). Small companies cant afford the licensing and production costs for a few thousand disks. Not to mention the convenience of being able to film and then edit directly on tape. Sure it takes a lot of time to duplicate a movie, but a duplication studio can be built in your living room. 1 master machine, 20 record machines. Perfect for local distribution or niche content. That sort of convenience pretty much guaranteed that a tape based product was going to win the market. Tape INVENTED "direct to home video" production studios and gave lots of budding directors a chance they never would have had otherwise, and a voice to underground / alternative creators. (Of course options like 8mm existed, but still, not nearly as "easy" to work with and distribute cheaply as tape) None of this is possible with laser disk , etc where the content had to be baked in during production (and for a LONG time, not possible with DVD either).

Something to consider too, is the quality of some CD mastering resulted in off-set, 'wobbly' tracks, or being so out of balance the vibration would cause tracking errors no matter what player you used. And then there was the matter of 'pin-holes' in the aluminum substrate, and later on down the road, oxidation, (everyone thought aluminum would last forever). It's great that you are re-visting this subject, but it's my generation that spent the amount of several months paychecks as early adopters, based on the supposed longevity, and sound quality, before actually being told of all the short-comings. Sony had it right by the time they started making the 1 bit converters, those decks where an amazing leap in sound quality that pre-dated better outboard DAC's as well as ushering in the ill-fated 1 bit SACD decks. I could have saved thousands, but I never would have imagined my entire collection the size of a living room wall, and now comprised of lossless files, would eventually fit on a 400GB chip smaller than my pinky nail inside a pocket sized player or smart phone. I wish Sony and Phillips would consider offering a refund to all of us that "Beta" tested their digital audio systems all these years.

The term "Superheterodyne" was coined by Armstrong to describes the use of a 'super-audible frequency' in its signal processing. The 'Beat Frequency' is not meant to be heard but used as an intermediate continuous frequency that can be enhanced thru one or more stages of amplification. Previously the Heterodyning process was to render a CW signal into an audible sound output, or demodulation thru direct conversion. Homodyne does much the same this with AM/FM radio be cancelling out the Rf by combining(beating) the carrier with an identical unmodulated frequency 180 degrees out of phase.. . . Whew!

Hi: first of all, thank you for the video: I really liked the part about the batteries! I'm not an electric engineer, but I want to add my words about pure sine wave. Even though that's what good UPSs do as well, and buying a pure sine wave inverter/UPS is a sign of good quality, computers and almost anything else powered by a switching power supply works just fine with modified sine-wave, and even better in DC. I power my computers thru a full bridge rectifier and filter capacitors (which can also avoid spikes and noise, like those caused by the generator), therefore at ~330-340 VDC (be sure to switch the PSU in desktop computers to 220/240V rather than 110/120V) Besides, using pure sine wave with capacitive loads will lead you to another well known problem: power factor ( When Nikola Tesla invented AC, it was a great invention, which solved (and still does) many problems for distributing electricity thru higher voltage wires carrying a much lower current (and therefore causing much less losses), for then reducing the voltage thru transformers. Nowadays the power factor problem is a big trouble, and some power companies overcharge their customers when using lower power factor devices: while overpriced electricity is not something you should care about, since you're drawing it from your inverter, you're stressing it. By the way, I'd have bought a 24, or even 48V inverter, and 2 to 4 smaller batteries respectively, therefore reducing the current by a factor of 2 or 4. Of course, that would require a different charger.

I actually had a Enterprise Appliance in 2001 that used DVD-RAM as its storage and archive at the 4.7GB disks as an option. It was super reliable but you know what all that was a big nothing because you still needed backups to the DVD-RAMS so we switched to less reliable and more expensive disk storage on a NAS because we could easily back those up with tape and quickly unlike DVD-RAM.

i mean they could have used a laserdisc instead. it would make the console huge but having that large disc would make coping impossible as laserdisc-r weren’t a thing. and the pressing machines were already there. The disc would store more data but I’m not sure laserdisc had good enough error correction. so it would have required making a laserdisc-rom standard which would be expensive. but a fun thought experiment

I don't think it is strictly true that two samples per cycle can reproduce the only signal that lead to those samples. If you sample (with 2 Hz) at 0 s, 0.5 s, and 1 s you will get samples 0, 0, and 0 from a perfect 1 Hz sine wave, i.e. y=sin(2*pi*x). Still, you would obviously also get constant zero samples from having no signal at all, and there is therefore no way to reproduce the original sine wave based on the three samples.

You're correct. The theorem states that you can only capture frequencies below the Nyquist frequency (1/2 the sampling rate). It's often misquoted.

I love your channel and you really make me laugh with your dry humour. You said that Oki say they had the first laser printer in 1991 but I worked in Peterborough, UK in 1988 and a company demonstrated a laser printer to us for printing courier labels. I was amazed at the quality because my previous job had been in a rostrum slide production company and the only way to get what we now call laser quality was to do it photographically on a typesetting machine or by using transfer letters.

It is possible that I am remembering wrong.. I am a tad old, but my first memories of VCRs were in the form of separate units - there was the VCR (VTR?) that recorded the tape and the VCP that played the tape (maybe this was in the days of beta?) The combo units followed shortly thereafter. As I said though, I could be remembering wrong. The only CED discs that I kept from my collection were the old LOTR cartoons: Hobbit, etc. I gave away all of the others. I still have most of my laserdiscs and I still enjoy watching them but many of mine suffer what is known as "laser rot" and are now useless. I've got a giant DVD collection but these days they sit in storage as I watch my various streaming services. I could never have imagined technology would reach this point but I'm glad it has.

Let’s not leave out the pertinent facts concerning the PAL standard: it was invented by Walter Bruch, a former NAZI electrical engineer. He designed PAL after first reverse engineering both the American NTSC and French SECAM TV standards. So PAL wouldn’t even exist if it weren’t for the foresight and accomplishments of the older established broadcasting systems. Bruch was also the inventor of the very first CCTV system...which the NAZI bastards used at the Peenemünde V2 Rocket launch sight. Any PAL advocates still warm ‘n fuzzy about “your PAL” now? Historia is too often glazed over. People should be aware of the truth and origins behind various technologies. The first version of NTSC was established in 1941. Color/colour was retroactively added in 1953. Development for SECAM didn’t even begin until 1956. PAL wasn’t shat out until 1962. The UK went onto adopt PAL in 1967, and eventually, much of the world.

It occurs to me, and I got a headache thinking about this, that the sound could be put on the tape with a spinning audio head if the tape were looped around the spinning sound heads and separated from the intermittent motion of the video recording. Much like the way sound is played back on a film projector in a constant motion while the picture part is stopping on each frame. Granted the sound would be rather poor, but it would be there and it's not supposed to be a musical recording. I'm a little surprised that such an easy fix wasn't used. Money?

Countryside electrical grid reliability is never good. I don't know what it is... every time I've lived more than 30 miles or more from a town or city, simple rain could cut the power for *days* and I don't understand why it took so long to locate and remedy the problems. One winter in the mountains of Virginia, back in the late 90's I lost power for over two weeks and couldn't open the front door because of the deep snow. I had to burn my dad's collection of rare books to keep warm and to make food on the wood stove.

Thank you for this video. As a European transplant to the US I hate the red/combined turn/stop signals. When there is a car just in front of and next to me on the highway, I mostly see only one of their rear corners in my side window. Every time they tap on the brakes I get a minor hear attack because I think it's the turn signal and they are about to turn into me having failed to see me in their blind spot. Speaking of blind spots, I am wondering if you ever made a video about setting up side mirrors? The typical driver's ed-recommended version which creates huge blind stops and the only "advantage" is seeing the back of your car (in case you forgot what color it was), vs. SAE-recommended version, described for example here
