Design all electronics for a sensor that use a voice recognition module. See attached PDF for manufacturer. Can use an alternative module, but needs to receive english words. This module uses pre-programmed typed words that systems listens for. Other modules need to be trained. Would consider other modules, but design fee needs to include simple method to activate voice training. When module detects words- data of this will be sent over TCP/IP via wifi to our server. It would send sensor ID, event, date, and time. Currently we a re using ESP8266 for wifi in other sensors. Good low cost. The sensor will need a method to connect it to the wifi network. Bluetooth or other very simple method. Creating the app to accomplish this should be included. All firmware to be included. The bid should include building 3 test units and all documentation for sourcing in for production in China.

Hello, I am exploring whether cell phones could be used to image molecular recognition events using terbium FRET (fluorescence resonance energy transfer). Some work has been done with cell phones:   [obscured]  /460802/Cost-effective_and_compact_wide-field_fluorescent_imaging_on_a_cell-phone Here are the specs for terbium FRET using conventional equipment: Excitation at 311 nm, delay 0.1 ms, gate time 1 ms, excitation and emission slit 8 nm, emission measured at 543 nm. The camera would need to take the picture 100 ms after the flash. Could this be done cheaply with cell phones? I dont know how much work this involves, thanks for your help, Paul

We have a requirement for a freelancer to create a PCB Layout for a development board. We have a schematic and a design file in RS-Online's PCB software "DesignSpark". The PCB Layout can be created in DesignSpark or Eagle and it must be to a manufacture's standard so that we can have it made. It must have all masks, screens etc. The Board is to be 2 layer. We have a PCB file already which needs someone with experience in PCB design and layout to look at it and improve it.

This will be a taxi security cam. It will take photos at certain intervals, store them temporary in the SD and push them to internet to be accessed afterwards. To simplify the schematics, the camera clock should be provided by arduino. I would like to use the OV7670 non-serial camera as it could be found relatively easy in Argentina. And arduino mini or micro. If possible. There are some examples of this camera with arduino on the internet Thanks

I need a case designed that can be 3d printed. The case is to hold a solar powered optical sensor. The case needs to protect from rain and snow, yet allow airflow through to keep the battery cool. The device needs to hold a solar panel (4.9 X 2.5 X 0.11 inches) and it needs a small window that will hold a small 1" square piece of glass. The case needs to sit on a slanted roof. The bottom of the case needs to sit at an angle of 18.43 degrees with a shavable line to allow for 26.57 degrees (or vice versa). The small window for the optical sensor needs to be parallel with the angled mount. The interior needs to hold a circuit board about the size of a credit card. And the entire space should be minimized as much as possible.

Short description: In this system, each table in the restaurant gets a battery powered wireless calling device with buttons. When pressed, this calling device sends a wireless zigbee or generic 2.4GHz message that will be received by one or more of the base stations of the system, which are based on Raspberry PI A+. The master base station memorizes the call status for each transmitter so that said information can later be polled over wifi and displayed by apps run in smartphones worn by the waiters. The apps for said smartphones are developed in a separate project ? you don't have to develop them. Deliverables for this project: ? For the calling device; scematics, PCB layout, MCU firmware ? For the Raspberry base station; software (including installer script that makes the software start upon boot) All software must be delivered with source code, and all source code must be professionally written and well documented in English. Suggested milestones (open to discussion before proje...

Need to design an Ultrasonic motion sensor and notfyer to be installed in the wheel arches of a car. Need the design to be able to build the unit myself. This project is to avoid parking tickets my creating notification when a parking officer marks my car tyres with chalk. When the parking officer moved their hand under the wheel arch the movement will be detected and I will be notified by text, email or key fob beeper. ( Range required approx 500m and within a building) The sensor could be mounted under the wheel arches ( the 2 front) or on the body of the car above the wheel arches. Ideally the components to build the project will be less that $250 and be available from online sellers. I imagine Arduino or rasberry pi will be the best options for a controller. Ideally the unit will be battery powered so I dont have to wire it into the car. With the bulk of the unit being attached to the dash an an on off switch so I can arm the unit when I get out of the car. Ideally the plans ...
