  1. emitter of a FET? on Researchers Design a Self-Powered Digital Camera · · Score: 1

    In figure 3 Q1 is drawn as a FET (and the circuit implies it is one) but they refer to the "emitter" of it when speaking of the drain.

    And obviously the goal of high resolution is counter to needing large cells to capture charge for harvesting.

    The design would seem to imply that the device cannot be self-starting. That is, if it runs out of charge, it has no way to activate the harvesting and get it self running again. Ah, I see in there it say they had to start with a charged supercap.

    It's still an interesting experiment.

    The 486DX2 was unquestionably the most famous chip of its era.

    Some other notes:

    The DX ran at multiple speeds, there was a 50MHz DX which was much faster than a DX2 for some things since it had a 50MHz external bus instead of 33MHz like the DX2/66. It was too pricey though. The DX4 (really 3x) ended that argument anyway and Pentium was also quick on the scene.

    The turbo button craze started with the 286, where it would often toggle 8/16 MHz. It indeed was huge in the 386 days.

  5. actually, NSFNET came after that on First Lawsuits Challenging FCC's New Net Neutrality Rules Arrive · · Score: 5, Informative

    And the government created that too. And the government decided eventually that confining the internet to just academia (as the NSFNET was) didn't make sense so they closed down the NSFNET and the main links changed to be commercial instead of government paid.

    This period you speak of where the ARPANET was the backbone for a network that was generally used never existed. The NSFNET started out around 1987 and you didn't see any real commercial use of the internet until the early 90s. Even CIX (ANS) came in 1991 with the help of the NSF. After Congress (including Al Gore) passed legislation pushing the NSF to repeal its restrictions on commercial use you saw significant commercial uses take off.

    Today's internet is in no way an unintended consequence. It may not have been paid for by the government, but they did design and develop it and were well aware of the possibilities beyond academia.

  10. Re:Why is the hardware so complex/expensive? on How a Kickstarter Project Can Massively Exceed Its Funding Goals and Still Fail · · Score: 2

    I can't see why. You can get an ATMEL microcontroller at least as powerful (or more) than that one for $3 to $7 (depending on how capable you want it to be) in small quantities (qty 10). That's the SAM D21 CPUs ($3) and the SAM 3N or SAM 3S for $7.

    I have to imagine the enclosure and such is more expensive than they thought.

    The hardware seems pretty basic. I could make a prototype version from the CPU I just bought in a week. Yes, that includes sound triggering, opto triggering, etc.

    Their AUX port seems HORRIBLY designed. They say it is powered, but you also can input signals? How? It's an RCA crown. It either can provide voltage and ground and look for a low resistance (short) across it, or it can receive voltages on it. If you really want to run active circuitry off it and receive a signal, you should use a 1/8" stereo jack and output power and ground and receive a signal in return. Then if you want to just use a short (like dry contacts) to trigger, you can ignore the power output, but if you want active circuitry you can do that too. Using the ADC to trigger is weird, even the $3 chip above has an analog comparator that interrupts you when a signal rises or falls and it can reference to things other than the 1.1V bandgap.

    I just get the feeling they weren't nearly as good as they thought as what they are doing.

    iBeacon helps your phone find itself and thus you. It doesn't let others map your phone.

    A merchant could make a system which finds you using iBeacon by self reporting. That is your phone finds itself and then an app on your phone tells the merchant. So if you want to find yourself, you can using iBeacon. If you don't want to, you don't. If you want the retailer to know where you are, you run their app which reports your location using iBeacon. If you don't want to, you don't.

    The other kinds of systems which track your WiFi signal around the store, where you are tracked without opting in, those are more likely to create privacy issues. Target already uses these kinds of systems.

    There were two Mac Portables before the MacBook 100/140/170 came out.

    Indeed both were enormous, each even had a lead-acid battery! The first one didn't even have a backlight.

    The Sony-designed MacBook 100 was actually designed to just be a smaller version of the original Macintosh Portables, which is why it also was based upon the much slower 68000 processor (the 140/170 used 68030 processors).

    The Powerbook 100 was well designed and small, but it wasn't really a big seller. The PowerBook 140 and PowerBook 170 took most of the sales. The later Powerbooks (145b, 160, 180, etc.) were all nearly identical to the 140/170 and not Sony's 100. This seemed to show that Apple didn't really take all that much from Sony's PowerBook 100.

    That is not at all true. A single fiber cannot handle the world's internet bandwidth. And the PON systems used for homes don't even dedicate 1Gbit to each termination (house). You don't have a dedicated connection to a chassis with 2,000 other customers, you are PON split from a single fiber with a lot of other houses, then that goes to a chassis.

    "It doesn't matter how it is shared as long as there is no congestion." is a useless truism. It's true for copper too.

    I think it's hilarious that you think that your ISP is only oversubscribing their links 2x (2,000 1Gb connections to 1Tb backhaul). That's fantasyland at the prices that residential customers pay.

  18. your washer has a cycle time? on The Great Lightbulb Conspiracy · · Score: 4, Interesting

    This is crazy. Just because the service tech told you something doesn't make it true.

    I have an HE washer/dryer that predates yours. I got it them 10 years ago and they're still going strong. It was the Maytag Neptune, which was the first HE washer on the US market. There was a flaw in the door latch on the first year or two model but I was lucky to avoid that, mine is from just after that.

    The washer works fine, although it is nice if you leave the door open for a day once in a while to dry it out in there otherwise, since the door is sealed, any moisture left in the drum after a cycle just sits there until next time you use it. It doesn't have anything to do with hot water, hot water only stays hot for a short time and hot water doesn't kill mildew anyway, if it did you wouldn't need to scrub or bleach the grout in your shower! Later models from Samsung and LG don't have this problem.

    The dryer doesn't even have cycle times. It just runs until the clothes are dry. It does this using a dryness sensor, the same type which has been around since 1980 or so. If you do run it on a timed cycle, you can adjust the time it runs in one minute increments. So I have no idea what your tech was telling you about mandating short cycle times or burners that aren't hot enough.

  19. it's simple math, similar triangles on Apple Edits iPhone 6's Protruding Camera Out of Official Photos · · Score: 4, Insightful

    On the smaller phone (iPhone 6) the lens is 50mm from the far (button) edge of the phone and protrudes 0.8mm. The phone is 7mm thick.

    Thus there is a triangle formed on the top of the phone which is 0.8mm tall and 50mm base. Now, if you make the triangle 7.8mm tall you form a triangle with the front plane of the phone, a triangle with a base (7.8/0.8)*50 of 487mm.

    So if you take the picture from less than 487mm away (half a meter) you can take a picture which doesn't show the camera and doesn't show the face of the phone (thus is "edge on") without using any photoshop trickery. The phone body will simply block the camera from view.

    And that's surely what Apple did. It's not hard to do.

    Also note: you don't have one, troll. It doesn't come out for a couple more days.

    That'd be 2900MWh times 61 or 177GWh. that's 177M kWh. A Tesla pack holds 85kWh, let's assume it's about to become 100kWh. And the pack costs over $10K, we'll assume it costs $5K.

    That would mean they need 1,770,000 packs, at $5K a piece or $89B worth of packs. It's also the entire output of the plant for 3.5 years.

  25. "some storage" on Tesla Plans To Power Its Gigafactory With Renewables Alone · · Score: 2

    From the article:

    "Reno gets an average of five peak sun hours per day."

    Remember, as soon as you say the word "average" you are counting on a huge amount of storage so that you get the average amount of energy every day, even if that day is below average. And even if every day for the last two weeks has been below average.

    In in fact, if you are using solar, you have to understand that nearly every day between the autumn equinox and the spring equinox is below average. That means you need enough storage to store up electricity all summer so you can use it in the winter! This is not at all realistic. More realistic is to make sure you produce more than you need in the summer and enough in the winter.

    This does use more than solar though. However, I can't believe this guy counted the windmills in a PR picture.

    Anyway, buying and erecting a 3MW windmill costs about $10M. That would mean Tesla would spend $850M on windmills. You cannot seriously think that Tesla is going to spend $850M on windmills before the plant even opens.
