Well, most accidents I've seen are fender-benders, and if your "emergency camera" is safely esconced in some that bubble-wrap wedged in under the seat, it would be out of harm's way, but accessible when the need arrives.
Being these are apparently designed for the masses, and not for the professional photographer who takes immaculate care of his instruments, I'll betcha they designed these babies to be quite rugged.
I will probably buy several of these.. especially if Ritz will give me my photos back in.bmp format or something readily compatible to it.
If they have a propritary format for the delivered photos though, its use to me is severely limited and I won't be using it for casual usage. I consider I own the copyright to the photos I shoot, and dammit, I don't want 'em crippled. When the article mentioned PC and MAC, I would have felt a lot more comfortable had I seen Linux mentioned too, then I would know the photo images delivered to me were not going to be laced with some sort of DRM, rendering the photos as trouble prone as music downloads from buymusic.
I don't care what format the leave the camera through... if they wanna encrypt it to protect their business model, fine with me. When they hand me my disk and accept my payment, there better not be any DRM on the disk, as I have no intention of placing any restrictions on them as to what they can use the money for.
And I also expect that I retain copyright to the photos themselves... I have no intention of agreeing to language like " we may share your data with our marketing partners as allowed by law." etc.
Like, when I wanna keep a camera in the car for those shots I always seem to miss... but if I do keep a camera in the car, the film goes bad in no time flat due to environmental abuses of temperature, humidity, and time.
This looks great for something if you get lithium batteries in it... looks like you could get all set up, and if the event you need to capture happens 5 years later, it should still work.
This would be very handy for documenting accidents, as you never know when you will get into one, and the probability is not very often, but when you do, having photos to document your side of the story could be very important.
Yeh.. I guess we like to stick with things we have learned and am comfortable with. I know times change, and things supposedly "get better".
I see morse code much like I see assembly language. It is the absolute lowest level you can drop to and get the job done. Morse lets you communicate with an absolute minimum of bandwidth, while the assembler lets you compute using the absolute minimum of resources.
I feel extremely comfortable around DOS and the assembler, as I feel I am right against the hardware itself, and have absolute knowledge of whats going on. With morse, you are right against the carrier. If you had to, you could communicate with nothing more than having two pieces of wire in your hand. You can build your transmitter from tinfoil, saran wrap, old radio tubes, and toilet-paper rolls if need be. Its a comforting feeling knowing no matter what goes wrong, you know what to do to fix it.
I often speculate we guys are a dying breed. It seems that everyone is happy just being a rider on the bus, and not worrying about knowing how to drive if need be. I have worked with too many large companies to see the paralysis resulting from what I considered very minor snafus.
I feel for your sense of adventure in accomplishing communication at such a level.
But, like camping, there will be those who "camp" at all levels. My neighbor's "camper" has amenities that even Hilton can't offer.
I will grant you that no sooner than morse code goes over the net, we will see more text-to-morse keyers and morse-decoder plug-ins than you can shake your proverbial stick at.
They will ruin the fun, much like a lot of those ham-equipment manufacturers took all the fun out of building your own rig to get on the air.
Do you remember the excitement of getting your first pair of 6146? Especially after using 6BQ6, 6CD6, or maybe if you were really desperate, a pair of 50L6???
Don't worry if those numbers mean little to you, they are old vacuum tube power pentodes used as horizontal output tubes in TV's and the 50L6 was the audio power output tube in those old 5-tube radios. We old farts know about these things, cause we used to build our old radio transmitters out of these things. On a good day, you could go around the world on nothing more than an old power tube from a radio or TV. With some 6146, you could go around the world damn near any time you wanted to.
That was when it was *really* fun. It seems to me that amateur radio has degraded into little more than internet chat rooms, where your bragging rights is more a function of whats in your wallet instead of whats in your head. ( or maybe I'm envious cause my wallet's awful thin. )
"I have no real way of knowing which are old and which are new, because
they all look the same."
Yeh. Get yourself one of those cheap little one cell flashlights. Say, your tape player takes four cells, charge them all up. Give em plenty of time in the charger so all get a full charge. Go ahead and use your player. If you note you didn't get the run-time you expected, just play it till it dies really good... then take the cells out and see which one won't light the flashlight.
I would tell you to go use a cheap voltmeter, but bad batteries have an annoying habit of giving a good terminal voltage when there is no load on them. I would tell you to measure the current the cell can source, but then if you mis-set the current measurement range on your meter, you've just destroyed your meter.
The flashlight bulb provides a good load as well as a quickie indication of the battery's capacity to source current.
The problem you mentioned about 7.2 volts is because the battery chemistries provide 1.5 volts for alkaline and 1.2 volts for NiMH. Hence, six internal cells provide 9 volts / 7.2 volts, and its a real geometric bear to fit 7 small cylindrical cells into the form factor designed for 6 small cylindrical cells...
Wash 'em just like any other glass. The dishwasher does not have any interrogation intelligence, so there is nothing to power the glass's processor with.
The central drink tracking computer won't be aware of the glass's existence until it has been placed onto a table with the appropriate interrogation circuit.
It oughta break just like any other glass.
And there is just about enough power in an energized glass to run your wristwatch.
Re: "And I'm still sitting here trying to puzzle out how the signal from the table provides enough power to run the circuitry in the glass.":
Inductive coupling. Those PIC chips don't require much power at ALL to run! Like in the microamp region. All they have to do is put a ferrite flux concentrator in the bottom of the glass, and it will coax the magnetic flux to intercept the energy pickup/transmit coil. The data could be easily be transmitted by selectively loading the coil in a serial fashion. The glass processor could easily use the energy coil's frequency as its clock, hence its serial output stream would be synchronous to its power source - quite easy to detect.
A couple of diodes and a small capacitor is all it takes to recover DC from the field to run the processor on, and those PIC processors are not picky at all on their supply voltages. My guess is they are doing "synchronous rectification" of the field, so they can "modulate" the power converter with the data transmit stream.
My parent post ( Direct Link ) has been modded redundant at the time I am reading it. The other post just before this one has the same information - and the same time stamp!
Colmmacc was trying to be helpful and save us a bit of searching, so he took the time to format up a link and post it, deriving no benefit for himself. And what happens? Smacked with bad moderation. Twice!
If I were tasked with metamoderating my parent, I would check the moderation as "unfair".
There are way too many perfectly good insightful comments that got no recognition so that one guy that tried to be helpful gets hammered.
Please, check your timestamps! And please save your negative mods for people who really deserve it, not people who tried to be helpful.
Yeh, they *look* unstable, but looking further, that looks to be an optical illusion. At least my mind tries to assume a uniform distribution of weight and arrive at a conclusion of how easy it would be to knock it over. It does look like this car has a weight distribution much like those inflatable "clowns" with the heavy bottom.. you try to knock 'em over and they just pop right back up.
These things sure look practical as the family "second cars", you know, the one you take when you need to go to work, shopping, school, etc, and save the Canyonero for family outings. At this rate, it looks like your common two car garage could house two Tangos and a Canyonero. I can see easily how each driver of a family could use one of these, kinda like each needs their own toothbrush. Hell, it wouldn't surprise me if they started making Canyoneros with onboard parking for Tangos.
It still scares me to think of it on freeways. I guess its just a size thing. The Tango looks quite practical for use on surface streets and downtown. Especially being its quiet and no fume. ( Actually, they might have to put some sort of noisemaker in it so pedestrians will know one's coming up from behind.) I imagine if it were mostly Tangos now downtown instead of cars - it would not be nearly as smelly or noisy.
I think they are onto something. It will be interesting how it turns out.
Yeh.. but somehow the idea of a 200mph crash in any car sounds scary to me.
I guess there's a lot for me to understand. Its not a crash with another Tango that scares me, its the crash with the Ford Excursion that scares me... and its not the fact he just hits me, its that not only does he hit me, he then proceeds to drive OVER me. The law of inertia would make this scenario inevitable. I don't know if this car's roll bar was designed to dissipate the energy of a ton of mass heading my way. But then, thats true with any car - its just that if you are physically bigger, you have a higher probability of simply getting pushed out of the way in lieu of being run over.
I know. Call me paranoid. I am this way because I already drive a small car and am I intimidated by these monsters I see all over the road? Hell yes!
My only advantage is I get about 40 miles per gallon.. but the disadvantage is I probably will not survive any substantial accident, due to my much smaller size/mass.
Yes.. I hate to be too critical of the design, bur you know inertia.. the thing that allowed a little piece of foam to do in our space shuttle. I am concerned about this inertia. Here you have half-ton of batteries traveling at some velocity with you right on top of them. Say, you collided with a SUV. I get the idea those batteries and their narrow wheelbase would go right under the SUV, leaving me with the SUV trailer hitch right in my mouth.
Its not the design of this vehicle itself that has me so concerned - I think its a really nice design for short low-speed commuting trips - its just that it has to share the road with monsters. I feel like a roach on a sidewalk. It won't make much difference even if they pass laws making it illegal to step on a roach. Its gonna happen.
Which leads me to my favorite pet peeve of the people who regulate use of the highways... why isn't there some law that mandates a certain standardized height off the road for bumpers, so that in the event of a collision, the bumpers take the hit? Or having heights of headlamps standardized?
This car really looks neat for general scooting around town...
But it looks in the photos to have a terrible center of gravity problem.. looks like it would roll quite easily.
Funny the article mentioned splitting lanes such as motorcycles... with the roads filling up more and more with SUV's, even the motorcyclists are ending up with more and more rapped knuckles from the SUV mirrors. Somehow I don't think its too practical for anybody to try to split lanes.
I don't wanna poke too much into this, but I question the phrase,
"Anyone installing a highly precise weight scale uses this data."
It was my understanding that this is one of the reasons for using a counterbalance-style scale in critical situations.
Variances in gravitational attraction affect both the object being weighed, and the counterbalance, in identical proportions, thus assuring the accuracy of the balance irregardless of gravitational force.
Just remember that $15/hour Maleko gets is probably from homeowners/individuals who are not writing off the expense, hence no need for tax records.
Consider if Maleko worked for a business, there would be all sorts of tax ramifications and deductions on the paycheck. Maleko would have to "earn" about $30/hr before Maleko got that $15/hr that was spendable.
I know this is not the legal viewpoint, but I can't see it as tax evasion, its just a question of who pays the tax. The homeowner who invited Maleko into the house to fix their personal machine is paying Maleko with money they already paid tax on, so why should Maleko pay tax on it again? However, in the case of a business, they are writing the wages of Maleko off as a business expense, hence Maleko is on the hook for paying the tax, which means Maleko would have to make about double the amount in order to end up with the same amount of spendable cash.
Another advantage of working for cash directly is you do not need to keep such an immense overhead of documentation of your business, where each penny went. You know how it is. You "earn" a "helluva lot of money", but in order to do so, you must spend a "helluva lot of money" to stay in the game. If you don't keep really good records on that "helluva lot of money" it takes you to play, the government taxes you on the whole amount you took in, leaving you nothing at all to live on. So, by clever stroke of the tax law pen, they have forced you to provide free accounting service to the government.
There is a lot to be said for low level cash business.
This is what I would do if I owned a music store and people started doing this...
I would turn it into profit. Pure profit.
Sure, I would gladly sell them any CD in the store they wanted. Thousands of them if they want. Let 'em clean me out if they want to to prove their point. I'll gladly take their cash, Visa, Master Card, whatever.
I will gladly refund their money the next day... in store credit.
That way, I have their money! And I have locked them into eventually purchasing something from me later at least the value of what they returned, as I can simply refuse to refund cash. Its my store. I make the rules. Thats the way business is. Ever seen a customer present a form to sign or an agreement to a retailer? They simply won't do it. But anything business wants, they just slip it in the form they demand the customer sign before the sale will consumate. Thats the neat thing about business. You can ask for anything and most sheeple will sign it. They may not like it and grouse, but they will pay.
Let 'em protest all they want, I have their money invested now in my accounts. Drawing interest.
And, if I am a big enough guy, I hire little minimum-wage minions to take the flak from the irritated public while I enjoy my luau in Hawaii.
I hate to see you received negative moderation at this point as I think you asked an honest question.
From what I have seen, the problem has been intercepting enough magnetic flux to recover enough signal to get a decent signal-to-noise ratio. If you have "access" to both sides of the magnetized domain, its much simpler to design your read/write head to detect/magnetize signal differentially from one side of the head to the other. Differential signals are much easier to recover the signal from than single-ended signals, as by its very nature, differential signals give you a reference to compare your signal against. That is you only worry about is A greater than B or is A less than B, you really don't care if both A and B are riding on a substantial amount of common-mode noise. There is a very common electronic circuit, known as the "differential amplifier" which is used for this sort of thing. It doesn't much care if the voltage levels of A and B have a lot of common "noise" on them, it only pays attention to the signal on A referenced to signal B.
So, as the two ends of your "pickup coil" in the read head passes over the magnetic domain areas "A" and "B" on the disk simultaneously, you get a clean signal.
Now the problem if the magnetic domains are vertical - you only have access to the surface. You can't really expect to get to the other magnetic pole to reference your read signal to. So its single ended. Now, you have the problem of trying to identify what is signal and what to reject as noise. You have nothing to compare your recovered signal to.
When trying to read a vertically-recorded magnetic domain, you no longer have the luxury of referencing it to the opposite pole of the magnetic domain of that particular bit. You can't get to it. Its against the physical disk platter. You can't get the other head pole in there to "look" at it.
I hope you get modded back off the noise floor - I would have tried, but that meant I would not be able to post... and hence unable to answer what I considered to be a perfectly legit question.
In a way, I would like to see the return of the days when people would bring rotten fruit and vegetables to throw at bad actors...
And use them during the ads.
And let the theater owners ponder the tradeoffs of running the ads and cleaning up the theater afterward, or just going ahead and show the movie the patrons paid for.
My experience with rodents is that they need to nibble on everything they can sink their teeth into. This includes your electronic stuff. Especially cabling.
And leave their body wastes whenever the spirit moves them.
" For what is keeping these illogical "intellectual property" laws in place? Their weapons."
I think its complacency.
Watching business antics is like watching cats eat.
I go out and get some food to feed to my cats.
The ferals are hungry too. If I don't watch them closely, they sneak up on my cats, distract them, a quick paw snatch, and the food's gone.
My cats survive either as long as I continue to protect them, or they learn to guard their food.
As I watch, people are much like my cats, I am watching freedoms our ancestors fought for disappearing pawsnatch by pawsnatch. And the ferals are getting bigger and stronger as the ones who never had to fight for their food laze back and let it happen.
There's still time to control this at the polls, before anything more drastic must happen to restore freedom of the people. But I don't think this is gonna happen.

I have been really wanting something like this.
Being these are apparently designed for the masses, and not for the professional photographer who takes immaculate care of his instruments, I'll betcha they designed these babies to be quite rugged.
I will probably buy several of these.. especially if Ritz will give me my photos back in .bmp format or something readily compatible to it.
If they have a propritary format for the delivered photos though, its use to me is severely limited and I won't be using it for casual usage. I consider I own the copyright to the photos I shoot, and dammit, I don't want 'em crippled. When the article mentioned PC and MAC, I would have felt a lot more comfortable had I seen Linux mentioned too, then I would know the photo images delivered to me were not going to be laced with some sort of DRM, rendering the photos as trouble prone as music downloads from buymusic.
I don't care what format the leave the camera through... if they wanna encrypt it to protect their business model, fine with me. When they hand me my disk and accept my payment, there better not be any DRM on the disk, as I have no intention of placing any restrictions on them as to what they can use the money for.
And I also expect that I retain copyright to the photos themselves... I have no intention of agreeing to language like " we may share your data with our marketing partners as allowed by law." etc.

Needless to say, my experience with rodents ( rats in my garden shed ) was not a good one, and led me to acquire a couple of cats.
Obviously, if you are keeping some in the house on purpose, there is something about rodent psychology I completely missed out on.
If you didn't keep 'em caged, how did you handle the inevitable mess?
Watching business antics is like watching cats eat.
I go out and get some food to feed to my cats.
The ferals are hungry too. If I don't watch them closely, they sneak up on my cats, distract them, a quick paw snatch, and the food's gone.
My cats survive either as long as I continue to protect them, or they learn to guard their food.
As I watch, people are much like my cats, I am watching freedoms our ancestors fought for disappearing pawsnatch by pawsnatch. And the ferals are getting bigger and stronger as the ones who never had to fight for their food laze back and let it happen.
There's still time to control this at the polls, before anything more drastic must happen to restore freedom of the people. But I don't think this is gonna happen.
