But in this joke tutorial I'm going to show you how you can get unlimited data for free, and this will work on any cell phone or cell carrier. It works by tricking your cell carrier into thinking you haven't downloaded any data at all, therefore giving you unlimited cell data to download.

HoloVect - first credible volumetric display? - Page 1
Forum section: electronics / general

timestamp: October 27, 2016, 02:29:45 am
content: So this is making the rounds:https://www.kickstarter.com/projects/2029950924/holovect-holographic-vector-displayUnlike the previous scams about volumetric/holographic projection, this actually looks plausible from a physical standpoint. It seems it is simply a standard laser projector/scanner, plus some kind of device that (their words) "modifies" the air (it has a grill) placed under the projection volume, to provide the Z axis by making the air refract/scatter the laser light. The big question is what does "modify" mean, exactly. Good old smoke/particulates, aimed across a moving slice of air? Something to do with heat? The grill seems to have thin slice apertures in it, suggesting maybe they're alternating between them to provide "curtains" of air at various Z depths:At one point in the video, a hand is shown interacting with the display, and when it moves to disturb the airflow the projection is disturbed, which is what you'd expect:Of course, this kind of tech is going to have a lot of limitations. The framerate is low, lower even than for standard laser projectors (and some of the shots in the video were apparently sped up); you won't be projecting any complex objects any time soon, as framerate depends on vector complexity. The shots in the video are careful to never show the surface directly in front of the laser beams - of course, in reality, your wall will be showing a very bright 2D projection of the object. And there is no mention of eye safety; lasers are not something you want casual users interacting with, and the laser will have to be pretty powerful since whatever process they're using for refraction will necessarily be quite inefficient.

author: Leopoldo
author_rank: Contributor
timestamp: August 09, 2016, 07:24:09 pm
content: It probably doesn't. It can't be always in focus, it must be set to infinity; stability is probably achieved with either image stabilization, being on smooth surfaces or both at the same time. Finally, it probably doesn't follow the pet, the user simply is able to rotate the camera; it would require a lot of effort to have a tracker for animal faces; maybe it could be using some sort of sound tracking, but it would be worthless with pets that do not emit sounds. The only task that the ball is capable of performing is keeping itself pointed upwards by using a counterweight on the bottom of the ball while rolling around. It moves just because it has 2 wheels under the sphere inside the shell.

It's based on the Atmel ATREB233SMAD-EK development platform and gives pretty accurate line of site positioning for hobbyists to play and experiment with. The boards we are releasing are a versatile 2.4GHz RF platform that not only measure distance and position between each other, they can even passively detect motion without any client hardware (see the updates for a demo video), or be used for a variety of other RF purposes (it uses the Atmel AT86RF233 chipset).Anyway, here goes.https://www.kickstarter.com/projects/subpos/subpos-ranger-indoor-positioning-system

I have created a "dataless" Wi-Fi positioning system that the Ranger works with to support this sort of functionality (http://subpos.org/?q=details), but I don't think it would see wide support because of the hardware requirements.Just using the Wi-Fi positioning system on its own however works with most smartphones that allow you to use the Wi-Fi scanning APIs (not Apple unfortunately). So if you don't mind the lower accuracy you get from distance measurements with RSSI, you could use that (it's all open-source).

Even though this is old technology it is still pervasive around the world. Living in downtown San Diego even many of the newer high rises use this tech. The only consumer facing devices I have found are the large chinese readers that copy to a T5557 type device so I sought out to make one anyone could use.http://tinylabs.io/keysyAny feedback would be appreciated. Planning on launching it on kickstarter to see if there is any demand. Currently should support any AM or FSK modulation with PSK support in the works.Also if anyone has any low frequency rfid cards/fobs I can test with (especially strange ones) please pm me. I'd be happy to pay shipping both ways or compensate you for them.Thanks and happy hacking-Elliot

Compatibility - Most of the cheap chinese readers I've seen only support one modulation/tag type. Ie: HID or em41xx. Haven't seen any that support PSK tags like HID Indala. My device will support all of these (currently FSK and AM, PSK under development.)3. My price point is around $30 which is on par with comparable chinese readers (see below) but with more tag support.ie:http://www.ebay.com/itm/Portable-Handheld-125KHz-RFID-HID-ID-Card-Writer-Copier-Duplicator-/201587054186

Our financial year is split in may, and the result is presented in august or september somewhere for companies.It's hard to have a small company and do all the paperwork yourself, so an accountant is often used. Saves a lot of time. Luckily I have no company, so my paperwork is very simplified. I just log in to my account with the tax office mobile app and press a button to sign.

Cats do it to each other as mutual grooming thing - classic mammalian group social bonding by making everybody smell of everybody else. The problem is that a cat's tongue is designed to groom fur and rasp the meat off bones, they actually have sharp little barbs on them. The result is that a cat's tongue feels like sandpaper, if they lick you more than about three times in one place it really begins to hurt.

No USB, because why would I want to waste space on a tiny MCU with USB.Anyway, unless they back up their rather unimpressive hardware with some very impressive learning resources, that is, a well authored in depth coursework, then the product is nothing. It's in the value add.

It screws up your buoyancy completely when you get to where the hose starts to resist.It is also a lot easier for the curled hose to get entangled in things underwater like propeller shafts etc. There are a couple of 12v powered devices for $150'ish with curled hoses and they are a PAIN to use. Fine for surface stuff and where there is no entanglement risk - but close to items that protrude - forget it... Hose is full of air so wants to float - usually (Murphy's law) and it WILL get entangled where there is just the slightest opportunity.I looked at it and thought - those guys have never dived a lot "attached" ... and went away.

With a lot of effort i managed to load software from their github repo onto the SRAM of the cypress part.The device was recognized by DSView. (Normal, since the vendor and device ID where correct now).But, the software was not able to communicate to the device further.After replugging the device went back to the cypress standard vendor / product id.Anyone has had the same issue? I'm a bit afraid i need to reprogram the FPGA.The how, i don't really know why it has lost the non volatile info. But i'm trying to get this thing working again..Any help is welcome!-- As for the mounting of no EEPROM, i read on the development board for the CY7C68013 that there needs to be a pin at high or low. Maybe forcing this pin on the other state, and mounting it, will allow me to set the CY7C68013 in EEPROM state.

content: In 2014 we launched the AllPixel: an easy way to control various kinds of digital RGB LEDs. This time, we wanted something that would bring that same level of ease to analog RGB LEDs. Enter the LongPixel.The LongPixel is able to drive 12-24V Common Anode RGB LED analog strips (the kind that have +V, R, G, and B wires). By using the WS2801 LED driver chip, multiple LongPixels can be chained together and treated as a "strip" of digitally addressable super-LEDs. The LongPixel can work with just about any platform that supports SPI communication, including the Arduino, the Raspberry Pi, and our AllPixel LED controller. The awesome FastLED Arduino/AVR library and our own BiblioPixel Python library are great control software options. Screw terminals, standard headers, and integrated mounting points make hardware setup a snap.Some example uses: Architectural Lighting, Costumes, Under counters or cabinets, TV Bias Lighting, or Music Interactive Lighting.As with all our work, the LongPixel is 100% open and all of the design files are available on GitHub (see link below).To help get the LongPixel into the hands of LED lovers at a reasonable cost, we’re launching a Kickstarter to help fund an initial run of the boards. We are also offering rolls of analog LEDs at a discount to backers: $25 or less for 5 meters. Checkout the links below for more details.https://www.kickstarter.com/projects/maniacallabs/longpixel-digital-control-for-analog-led-stripshttps://github.com/ManiacalLabs/LongPixelThanks for reading!Adam and Dan, Maniacal Labs
