They must have found someone that snores continuously without interruption for taking breath and at a constant sound level, though it doesn't look like like my wife...Also the the sound pressure will naturally drop as you move the sound meter away from the source, irrespective of any BS noise cancellation. Start at 1" and move to 8" and you've already dropped ~18dB.

content: The charging IC is only rated at about 50mA, which means you could, at best, charge your phone with 50mAh of energy.How much energy does it take to call? My S4 pulls 0.6A @ 5V idling on the home screen with 100% charged battery. Say it takes 60 seconds to boot the phone up & book a cab and power consumption is the same throughout, although in reality if the CPU and radio are in use, the power consumption will be much higher. That would use 7.4mAh @ 3.7V, but "90 seconds of shaking" would only generate 1.25mAh if you could somehow reach the maximum power point of the device.So their claim that you could make an Uber booking by shaking for 90 seconds is dubious, at best (I smell a rat)

content: Quote from: tom66 on January 13, 2016, 01:30:34 pmWell... misleading at least. It's entirely possible that the event occurred as they described:- The ampy was used until fully discharged, battery is cut off by the LTC1540 comparator (with hysteresis!) (battery voltage during discharge load condition would be lower than no-load voltage)- While not used, the battery chemistry in the Ampy recovered some state of charge, but didn't raise the battery voltage enough to overcome the hysteresis- shaking the ampy applied a charge voltage at the battery and the LTC1540 which overcame the hysteresis, reconnecting the battery to the boost converter- enough capacity was left in the battery at this point to charge the phone for the single phone call (phone also will "shut off" before fully discharged to protect battery)The article was musing about why all the parts are from LT... Easily explained, an LT sales engineer designed the circuit for them

If they made the input range up to 20V then you could at least use an 18VDC laptop brick that most of us probably have. And it would take very little to just toss on an OLED display and a button or two and forget the PC interface. PC interfaces are really overrated when you need a minimal set of buttons and/or dials to begin with, IMO.https://www.kickstarter.com/projects/949348142/single-channel-dc-power-supply-for-your-electronic?ref=category

content: A pile of bizarre design decisions, too low voltage, should be sold with a plugpack, shouldn't need two PCBs.Even it's one distinguishing feature of BT GUI control is crippled by it's ridiculously low information density GUI. For multiple supplies they shouldn't use windows, the GUI should be designed suitable for multi-supply use with the GUI layout corresponding to the physical layout (to slightly reduce the usability loss of not having a quick way to see what wire corresponds to what voltage as you can with a traditional supply).

content: Piece of s--t.The terminal blocks wont stand up to repeated connection/disconnection - should have used pluggable ones or standard 4mm Jack socket/binding post combos.As already mentioned, insufficient output voltage.There's no mention of isolation - the output needs to be fully isolated so you can stack them in any combination. As is, how do you get a negative rail?Putting USB on each one is *DUMB*. They are obviously serially controlled (see terminal window) so why not use a single USB <=> serial cable for the whole stacked bank.
The "Joey" 7-segment LED display board for Raspberry Pi - Page 1

content: "Feel free to promote your crowd funded project here..."Ok, if you insist!I launched the "Joey" - a little numeric display, which hangs off the side of a Raspberry Pi, nearly a month ago on Kickstarter:http://kck.st/1OudIq2And I'm happy to say that it's been funded! But there's still nearly two days to go, so if you have a Raspberry Pi, you still have a chance to grab one!Why a 7-segment LED display, when OLEDs and LCDs are so much more "now"?As I wrote in the Raspberry Pi forum:The Joey is designed to be genuinely useful while not getting in the way. But sitting off to the side, you can still see the display, even if you have a HAT or other expansion board mounted on your Pi. And because it connects through I2C, and doesn't use any other GPIO pins, it's likely to work alongside any of your other add-ons. See the Kickstarter video to see what I mean...And besides, LED displays have a nice friendly glow!It's handy for finding your Pi's IP address if you take it to a meeting, or displaying a reading such as temperature, or even the time of day. And yes, we provide the software for all of those, along with a Python library that even allows you to display words on the Joey (admittedly, "M" and "W" are pretty dodgy on a 7-segment display...If you want one, go to:http://kck.st/1OudIq2

content: That's a pretty neat kit! It looks like a lot of fun. My only concern is that it may be a bit "fidgety" as far as assembly. The kids will enjoy putting it together.... but does it have to be perfect? Will it connect precisely enough or is there "slack" built in that could allow the marbles to fall off their tracks if things are not perfectly aligned when they are glued together?We have another marble kit that actually has an infinite combination of options available. You build it out of several different types of pieces (like LEGO) that cause the balls to go different ways. It is called Q-BA-MAZE 2.0 and you can see the video of it in action here:You can make lots of different combinations of pieces and build large mazes. The nice thing is there are "splitter" and "combiner" blocks so you can put them together in ways that you do not know where the marble will go... It has a 50/50 chance of going down one path or another. So you can create systems that the kids can learn about probability by seeing where the marbles tend to drop to (like the Plinko game).

content: My name is Connor Nishijima, and I've been tracking the approximate mood of the online world since August 11th this year and displaying in color data on my desk.How is this possible? Some Twitter, some Python, and a bit of ESP8266 magic!Here is a video:Thanks to awesome developments in the tech world this last year, I'm able to use a $5 VPS to read 2,600,000 tweets a day, search for hundreds of keywords in 5 languages, and detect levels of 6 emotions:Love (Pink), Joy (Yellow), Surprise (Purple), Anger (Red), Sadness (Blue) and Fear (Green).The word counts found for each emotion are totaled up every minute, and the most recent data is compared to a Weighted Moving Average of the last 2 hours, to produce a percentage value. For example:If for two hours about 1,200 tweets per minute about Love came in, but the most recent minute saw a spike of 2,400 t/min, the estimation for Love would be at 200%.These emotional levels are then squished into 25-byte summaries and made available in plaintext via Apache2 on the VPS. Every few moments, an ESP8266 WiFi microcontroller requests this data, and parses it into a twisting color light show, thanks to the awesome 9x WS2812B leds inside. (NeoPixels as you might know them) I call this device a "moodLight". So if enough tweets like this came in:“I am so proud of my son for getting his degree! I’m going to miss him at home.”"Proud" and "miss him" would result in a bittersweet twist of Joy and Sadness in the moodLight. This system can be used to keep tabs on the summarized emotion of the online world, so if it fluctuates with some sour colors all the sudden - you'll know to check the news before it's even written.Because of the wide interest shown on Reddit for my prototype, I launched a Kickstarter yesterday so people could get their OWN moodLight as well! It overfunded in just 17 hours. If you would like more information about the lamp, or to get one yourself, please visit my Kickstarter using the KickTraq image below.MoodLighting emotional analytics availableHEREandHERE!- Connor

Moving the nearest metalic component away from the head can in my opinionreducereceived doses, as the intensity of a field weakens with the square of the distance (assuming a normal pattern).edit:The 100% is obviously bollocks. You still get the full dose where ever you put your cell phone (pocket).

There are quite a few cases of cancer and eye-damage that can be directly linked to working with/operating these radars in Germany and other countries.

EDIT: No, they are taxed the exact same way (not sure about writing off stuff), but they have to now be checked by 3rd party to see if what they are doing actually benefits society and environment... So they can't just operate and do anything to maximize profits if it goes against that mandate. A good P.R. move definitely, and they are going to give back some of the profits to help people and not just line their own pockets.BUT.... What is their "benefit" to society if they ignore calls by backers to flag dubious campaigns? Sure they can make some more profit by accepting a bad scam campaign, then give it back to society. What about actually NOT accepting the bad campaign or listening to backers who complain? Wouldn't that be more important?

Could have got cheaper ones for $50 !! I could set these cameras to detect motion and send snapshots to my email address. Not only that I could view the cameras in real time from a PC or Android phone device half way round the world !! They also had night vision which would automatically switch on a set of infra-red leds. They also had remote pan and tilt which is a definite requirement for security apps which this Indiegogo camera does not have. All the features that this dude on Indiegogo claims to have can be found on a much cheaper and more flexible camera off ebay.These are the specs for the units I bought.QuoteNow this dude wants $199 for starters and the punters have jumped in and ordered over 350K of kit !!I don't get it ?cheers
