Hello, I need a report and/or spreadsheet that outlines the majority of fitness bands on the market. What I need to know are: Manufacturer Model Blue Tooth 4.0 ((BLE) ? Acceleromter/brand/device Gyroscope/brand/device Magnetometer/brand/device Android Compatibility iPhone Compatibility Software API that allows access to streaming of raw sensor data? If yes, what is the max sensor streaming rate? (>50Hz required) Average Price Many bands such as Fit Bit, Jawbone, Adidas X_Cell, etc provide higher level software API's with no access to low level sensor streaming data. The Android Watches, Microsoft Band and Pebble watch do indeed provide for this. Please help me find low cost fit bands that provide access to low level sensor data as well as the additional information outlined above.

Hi, this project is about developing 3 micro circuits (1 of them is remote controller). I need developer to make the following microcircuit: 1) Micro circuit with LED lights strip (6 LEDs) remotely turned on and freezing for 8 seconds, and then self shutting down. size: 80x30x8mm max Working Voltage - 12V max 2) Micro circuit with LED lights strip (6 LEDs) remotely turned on and freezing for 8 seconds, and then self shutting down, size: 80x30x8mm max Working Voltage - 12V max 3) Micro remote control (not IR), it is desirable to radio waves (or Bluetooth). Which will operate at a distance of 10 meters (max). The purpose of the remote control is to switch on LED lights described above. So remote control will have only 2 buttons (each button turns on each device with LED strip). size: 45x25x10mm. Working voltage - 3V max. Briefly, I need 2 separate devices, which controled by remote control (3rd device). Budget: TBD

Hi, I would like to hire someone to build a circuit board with electric shocking element. Please only countries that can safely ship this without risk of it being seized by customs! In the attached pictures, you will see what the final product should look like. The schematic shows the device I currently have. What you create will be identical except that it will probably not have a voltage regulator and it must also have a potentiometer. The shocking element will be at the end of wires attached to the PCB. There should be a potentiometer added to the circuit adjustable so that the shock is mildly painful at the highest setting and almost unnoticeable at the lowest. In the middle it should tingle just enough to wake someone up if they were sleeping. I do not know what voltage are necessary to do this, so you would have to experiment on yourself. The board should fit inside 2.3" x 3.7" and accommodate a 9V battery. If this is possible and you can do it, please message me...

I have a schematic, but now the board needs to be designed. The board is 'sandwiched' between two other boards (a O-Droid C1 and a GPS receiver card), and provides some other interfacing (rs232 and rs485) and power to the other boards. I have an Eagle schematic with 3 x serial ics, 3-4 other ics, three headers and should fit into about 100mm x 100mm board. Okay to use 4-layer board. I have also defined some of the pcb pads, but these will need double-checking. There are a few other constraints, such as a cutout for an SMA RF connector. Attached is a pdf of the schematic, but all Eagle files and libraries can be supplied if required.

Hi, I need to control a Canon DSLR camera via a raspberry pi. I know the system is currently being used by other people but want to build and develop my own. I will have a camera in a remote area and I need the following. The Pi to talk to the camera and control the cameras interface so we can change settings. For the Pi to be able to run programs that change the camera settings slowly, so at one point in time the cameras shutting speed is x and over 4 hours slowly changes to y. The Pi to receive the images from the camera and store them on a hard drive. The Pi to talk to a 3G modern and for me to remotely control the camera and view the latest images. The Pi to send the images over the 3G modem to my server. Help setting up the 3G modem, suggestion of what to buy and then setting it up. Suggesting what kit I need to buy as currently I own nothing apart from the camera.

We have two components that need to be connected together with proper power and programming interfaces. The PCB needs to be no larger than 2in x 2in. Ideally we would like to have a PCB antenna (2.4Ghz ZigBee), but will settle for a chip antenna if it means space savings. The RFID antenna will need to be PCB. There also needs to be a connection for an RGB LED. ZigBee System-on-Chip: Atmel ATmega256RFR2 RFID: STMicroelectronics ST95HF Battery: two 1.5v AA alkaline LED: Generic RGB LED

I am interested in designing, developing and manufacturing a RECEIPT size ONLY document scanner proto-type using off-the-shelf electrical and electronics components. Here is a brief functionality description: Upon sensing the paper in the feeder auto start the scan and store the file on SD card in JPG format. There is NO USB port required for file transfer. Only 2 ports required are: for charging the internal battery and the SD card slot. I am developing this proto-type for a project which will require 100 scanners. Upon project success many more scanners will be required. I need quotes for the design, development and delivery (California, USA) for 100 such scanners. If possible, do give quotes for 2-3 variations of the components / functionality. Contact me for any additional considerations needed for making scanner more efficient or cost lesser. Budget in the job description is indicative. The details specs are below. Paper sensor: mechanical or optical Auto launch / scan star...

I'm interested in creating circuit and PCB schematics for RS232 analyzer device. Main functional is to show RS232 sniffed data on LCD screen. Device should have two RS232 ports to be able sniffing data in both directions. LCD screen should have touch screen. Only one additional button will be used ? power button. Device should run on rechargeable batteries and be able to recharge from USB. I'll write program under Arduino IDE myself. I'm waiting to receive circuit and PCB schematics in one of the popular PCB design software (eg. Eagle). All electronic parts should be available from Europe supplier (eg. Farnell/Elfa/Rs-delivers). Most of the parameters could be changed up to your expertise. If you have experience with some similar component, please use it. I have no strict limit in time, but waiting for the price to be reasonable, since I'll use this device for my personal purposes. Parts description: - MCU - Atmel SAM3X8E ARM Cortex-M3 (I'll Arduino IDE for programming). Could be cha...

We are an architect and construction firm in need of a single project solution for a house currently in construction. We would like to have a series of 15 windows operate by two decision statements 1. Im in sunlight 2. It's more tolerate outside than inside (74 deg). I think this is a simple electronic engineering gig and it's ok if we use off the shelf kits. Motorizations is purchased and 110 v system. If this is in your wheelhouse please contact me.

This project is to design a high-efficiency, compact MPPT Charge Controller based on the attached IC (LT8490), to be used with the attached lithium-ion batteries. The batteries will be attached in a 4S configuration. Each battery is 4.2V, but the charge controller is to only charge them to 4.1V each, or 16.4V for the entire pack. They are to be charged with a CC/CV profile, as per their datasheet. (Configuration of IC on Pg 13 of 8490f.pdf) The charge controller should be optimized for 1-2A of incoming current at 24V, but the locations and parts that should be changed to increase this capacity should be clearly marked in additional schematics. Thermal considerations should be taken into account with component choices, and all possible components should be at least X5R or equivalent. A thermistor divider network should be in place for temperature compensation/shutdown of battery charging. If possible, enough thermistors should be allowed to monitor each battery on the TEMPSENSE pin ...

Looking for someone who can do PCB layout for me, preferrably with orcad layout. I have all schematic ready, footprints/padstacks of components ready. Board will be approximately 3x3 inch. Half of the board is already laid out (due to existing reference design). There are about 50+ components to layout and about 10+ datasheets that have details of layout guidelines.
