Re: Why hasn't the 3.5mm jack/port been shrunk?

And that is another reason why I can't fault apple, the technology exists regardless of the 3.5mm connector. I have a USB headset on my desk right now.  Fidelity is reasonable for the $7.00 I paid although I only use it for Skype. Apple is just going to put a Lightning connector on existing technolo...

Re: Tesla Model S Totaled Due To Battery Malfuntion

Yes, I was trying to describe our situation in California. For all the sun and good jobs, you pay a hell of a price to live here and get ripped off at every turn. For an example of our energy economics look back at the rolling blackouts and automatic rate hikes that we had a while back.  Producers w...

Re: Why hasn't the 3.5mm jack/port been shrunk?

Unilaterally creating a new plug seems to be much worse than using an existing standard.  The last thing we need is format wars for headphone plugs.  Apple is only going to upset Apple users if the idea is a dud.  Since I am not an Apple user, I can live with that. I agree that the lightning connect...

Re: Why hasn't the 3.5mm jack/port been shrunk?

The main thing that's "wrong" with it is that it is moves (ie, the male connector rotates within the jack). This allows for unnecessary disruption of contact. The trade off is built-in strain relief, which can be handy for jacks meant for portable devices. You will see, though, on higher ...

Personally, I hope nuclear fusion doesn't become possible, simply because it will immediately trend itself towards a fusion/neutron bomb. If that happens, goodbye humans.

Re: Why hasn't the 3.5mm jack/port been shrunk?

Everybody focuses on size but the fact remains that the 3.5mm stereo plug is a poor connector design. Remember IDE hard drives with 40 pin connectors and the transition to SATA with it's nice easy to use connector? That is modernization. The force working against modernization is inertia. I hope  al...

Being a Californian, I don't know anything else.

Re: Case Dust Filtration

How hot does your PC run?

Re: Why hasn't the 3.5mm jack/port been shrunk?

I think the biggest issue with the 2.5mm phone jack is that it is too fragile.  The plugs fall apart if you bend them at all and their tiny size makes that a frequent reality. I personally think 3.5mm is on the too small to be strong side and 1/4" plugs are rarely built to a standard that I wou...

But let's talk about gas tanks.  People who like EVs seem to make them out to be extreme fire hazards but the reality of what it takes to cause a gas tank fire is very very uncommon and usually can be traced back to negligence of the operator or things like 60 mph rear end collisions.

There is no California law requiring a gun safe to buy a rifle. If you don't own an approved safe you will have to buy a cable lock. As for what rifle to buy, that is a personal preference thing and depending on what type of shooting you like and your budget some rifles will be more appropriate than...

Re: Tesla Model S Totaled Due To Battery Malfuntion

That fire was caused by sloppy engineering, no doubt about that but unless you put a fuse inside the battery there is no way to protect against a dead short. The incident was across two 12v batteries connected in series inside the pack so it only took 24v to start the fire. It probably wasn't enough...

It wasn't a conversion, it was just quite a while ago and was lead acid because NiMH was cost prohibitive and Lithium batteries would be a small fortune.

That is another reason for line arrays, if the sound wave is created floor to ceiling, it behaves like it is radiating in to a 2D space rather than a 3D space and as such the amplitude does not fall off as quickly with distance so you will get a bigger sweet area and the difference in volume from th...

Traditional line arrays run in to all of those problems but all of those problems have a solution. I think the phase problem you speak of is diffraction caused by driver spacing.  That is a very real problem because an ideal line source has a maximum driver spacing and line length for every frequenc...

Re: The impending death of the 3.5mm audio port gains a new ally

Less impedance just means heavier gauge wire in the voice coil, kind of like one of the mini speakers that you can find all over the place these days. The issue then is that mini speaker have horrible sensitivity while also having enough excursion to blow out your ears in a headphone. You can solve ...
