This is an attempt to make a fully autonomous device that can be used without computer or smartphone, and controlled directly from built-in LCD display and buttons. The main idea of Flipper Zero is to combine all the phreaking hardware tools that you could need for hacking on the go.Features:433 MHz range support (CC1111)Infrared125 kHz RFID reader/writer/emulatoriButton 1-Wire reader/writer/emulator(Maybe) NFC reader/writer (NXP PN532)I would like to hear your opinion before crowdfunding started.

I'm tired of devices that can only works via smartphone application. But I clearly understand that lot of operations cannot be done just from 6 buttons and tiny display, so we are thinking to add bluetooth to version Zero, with simple NRF chip. Also we are developing a bigger version called Flipper Onehttps://flipperzero.one/onebased on i.MX6 SoC and powered by Linux. It will have WiFi and Bluetooth.

content: The Flipper Zero is a great idea! Looks like goodDFMtoo.May I make a suggestion? In the area near the USB-C connector where there is an inductor, could you place a small grid of pads with power, SPI, I2C, and interrupt broken out? Then people could 3D print their own lower part of the case with custom electronics which would connect to the main board. If you have the board area, and will release CAD files for the case, it could be a compelling selling point.

content: There are better ways to spend $150Also 10 Ohm load @ 1GHz seems like a measurement error to me. Just based on capacitance that would translate to 16pf. Also the other measurements look fishy. Just look at the bandwidth graph; the commercial 1.5GHz probe doesn't even reach 1.5GHz (-3dB). I find that odd.

content: The case is nice, and if they figured out a good way to put adjustable/replaceable tips on the probe while keeping acceptable performance, then that might be worth it to some people.In the meantime, I've acquired a set of transmission line probes, 3 GHz and above, on ebay, for similar or less money, and I have built several.500 ohms is low, I agree with really wanting 1 kohm, and really wish I could get more.The comparison data seems sketchy to me. The $2k 0.99 pF probe is probably a FET probe with 100 kohm parallel resistance. I would take the comparison more seriously if they listed the probes to which they compared it. A picture of the setup used to measure the probes is just as important, otherwise the comparison is not very meaningful.I do admit that even simple EM problems look much more impressive and are easier to sell to management if you have a nicely colored simulation.Finally, I would not be so quick to dismiss the importance of the coax cable quality. Just because it's rated for high bandwidth doesn't mean its good.If the effort expended makes eventually results in a transmission line probe with better performance for similar money, that would be great, or if the price was more like $50. I don't see that the current iteration is much (or any?) better than I can do with a piece of high quality coax and a resistor.John

content: The 2 micro USB connectors appear to be surface mount only, and not only that, the mechanical pads are only connected to the ground plane by thin traces; that is going to rip from the board after 2 or 3 uses. I would recommend to at least merge the 4 mechanical pads into the ground plane if you can't switch to a through holed connector at this stage. Thermal relief should never be used on mechanical or RF ground pads.

I cannot believe that they are able to get any reasonable current output from that cell. This is probably similar to a metal-air battery, like the ones used in hearing aids. Once activated, it will generate a steady current for a limited amount of time, use it or lose it.

But it will have the same problems as water activated lanterns/flashlights (ex. Hydra-Light) in that yes, once activated it cannot be stopped (though often stops before fully reacted) and the cells wear out/self degrade easily if not stored or cared for properly (any residual moisture in the device after use or excess humidity will ruin the cell).Water lights usually only run 2-3 times per cell max. So 100 times or even 10 is absolute

content: I wouldn't put all the blame on Fluke though. The way trademark law works means you could lose a trademark if you don't actively enforce it, and Fluke's legal department is just doing what they have to do to protect their trademark. The problem is the fact that trademarks (and copyright) can be interpreted to such a broad extent in the US (most known example is mickey mouse copyright that covers anything with one large circle and two smaller circles). Most other parts of the world have far narrower definitions of what can be trademarked, for example China has a strong "generics" doctrine which led to companies denied registration of their own trademark that is well known in other countries, simply because the market was already flooded with bootlegs and the name was seen as "genericized".

I apologise in advance if this makes you uncomfortable.My college tuition is way to high, about 800 USD per semester and since I started studying I've been able to obtain a scholarship that my university gives to the student with the highest grade in a semester and it helps by not paying next semester's tuition fee.Two months ago my father passed away and I hadn't been able to obtain the scholarship mentioned above. Now, I have only a few weeks to gather money in order to pay for my tuition and I'm going crazy.I've looked for a job without any luck and I have too many bills to pay.As I mentioned, I'm from Perú and I study in Colombia with a student visa which is about to expired and I have to pay for that as well.So, I really hope you can help me and to do that I've created a fundraising campaign in a Colombian version of gofundme because I'm not from usa:https://vaki.co/1576924844039Thanks in advance!

Water use may or may not be an issue depending on where we are talking about. Rice takes 2,500L to produce 1kg, should people stop eating rice? No.

I'd guess cheap and reliable can't be attained at this price. If they included a 2-cent, 40-hole plastic piece (used to make headers) hobbyists could slide it on over the Joey to sort of re-align the header pins?

content: Quote from: Cliff Matthews on October 14, 2015, 07:37:49 pmAh, the Joey. Had to stop selling it and get rid of the stock, after receiving a "cease and desist" from a company that had registered the name "Joey". Also abandoned the "Joey Zero" I was about to release, that had a proper connector instead of the staggered sliding one.Anyway - it took a few revisions to get the staggering right. Slow process because I had to get each interaction manufactured (couldn't test by drilling them myself, because fractions of a mm were important). Had to balance making a good connection vs ease of fit and, as pointed out above, how much it splayed the Pi's pins, making it harder to fit another board on top (which was the whole point of the Joey being a "sidecar").In terms of long term reliability, yes, the issue is that the hole plating will eventually wear through after repeated removal/replacement of the board. The idea was that it would remain attached to the Pi most of the time, while the user swapped their various hats - it only interfered with I2C and the address was settable via jumpers, so could coexist with almost anything.History now of course, just wanted to comment because I hadn't seen this post from years back!

Then, program it yourself or control it remotely using the included software.Some key features:USB charging2 motor and 2 servo connectors on boardProgrammable current-limitingArduino compatible + library support for telepresent functionsFree desktop "Control Panel" to control robot over the internetFor a full list of hardware and software features check out the product page:https://www.arxterra.com/3dot/buy-now(also check out the robots we used it for..)These boards have spent years in the making and have undergone many revisions as they are test-run in assembly and c++ programming courses at California State University, Long Beach. We currently assemble them in-house using a mostly homemade pick and place machine and some hand soldering. We are looking to use the kickstarter to ramp up production, outsource PCBA and be able to sell the board for a much lower price!First, however, I would be very curious to hear all your expert feedback!Features you would like to see? Concerns? Would you be excited for the kickstarter? Let me know!Our mailing list is athttps://www.arxterra.com/join/Jaap

content: Hi,I was looking at the Kickstarter campaign of the Tilt Five, and I noticed something interesting in one of their animated gifs. The one I'm talking about is this:What bothers me is that in this gif that's supposed to show how well their system works, there are too shots were the camera is panning left and right with the glasses affixed to it in a fixed relative position. In these shots, you can just see the gaming board outside the glasses frame, and even though you are not looking through the glass, you can still see the projected virtual gameboard content. These stills show what I mean.So, is this possible? I mean, is that "okay" that the camera can see the virtual objects outside the glasses, or is this another faked demo? The latter would conclude that the campaign itself could be scam or at least pretend to be much closer to being market-ready than they really are.

It inserts into both of them, firmly bridging them together mechanically and electrically.Compared with jumper wires (the de facto way to connect Arduino and a breadboard), BreadShield is cleaner, faster, and can be used in conjunction with shields.If you have any questions or suggestions (we can still make changes to the design), feel free to fill out this form athttps://www.crowdsupply.com/loser/breadshield/ask-question

So we introduce the BreadShield.For example, it takes 11 jumper wires to connect Arduino with an HD44780 LCD (in 4-bit data). With BreadShield, just one.Enjoy having all Arduino pins on your breadboard instantly, or swapping with a different breadboard swiftly.And more: you can use other shields along side the breadboard, unlike the cases before where the jumper wires take the precious sockets for shields.Last but not least, it’s open hardware. We plan to make our Github repo public with all design files and our thoughts in iterating the prototypes.We are now pre-launching a crowdfunding campaign to bring BreadShield into a reality.Subscribe (and support us later) on Crowd Supply at:https://www.crowdsupply.com/loser/breadshield

content: Greetings folks.. I've created a Carbon fiber and billet aluminum high performance Raspberry pi case. As passive cooling cases go, it is likely the best you can buy. Overclocked to 1.5ghz you get no throttling even after 30 minutes. There is no thermal pad nonsense as it is perfectly machined with a flat surface that exactly fits the microprocessor and ethernet chip. As a bonus it has the high performance looks that no other cases can touch.Follow the links and I have some videos and some thermal testing data.Why is it so expensive? Real carbon fiber and a precision machined case isn't a low cost endeavor. I didn't cut any corners. I was tired of crappy cases. Of course there are cheaper options and everyone else has gone for cheap. We have gone for the win. #piday #raspberrypi #winningUse coupon code "winning" for $10 off!https://www.macsboost.com/product/mcpi-carbon-fiber-aluminum-racing-raspberry-pi-case/I've already made the investment and have them in stock now so no crowdfunding risk to you.

Building a follow takes content, lots of content that people are interested in.What you should do is try and get your product or whatever it is reviews / talked about by influences (hate that term) in you target market.

That is something you can build "relatively" quickly (over a course of a few months, maybe even weeks). This is vital to catching media attention and drawing in new masses when your campaign launches.

content: The rise/fall time of the FETs is about 0.15ns which is calculated from its typical on state resistance (3 ohm) and load capacitance (50pF), so it could technically support into the GHz range under ideal conditions. However the circuit itself and connectors are definitely not designed for that. I am going to have some more in depth tests in the coming updates, but with what I have on hand currently, 50MHz square waves get through without too much attenuation and distortion (so say ~200Mhz bandwidth currently as a safe guess).
