I want to make a wearable device that would have a microphone that would pick up speech and send the audio via bluetooth to a speech to text iphone app I have already completed. Then the app would send the text message generated to a screen on the wearable device. Am thinking either Arduino or Rasberry Pi (or something better?)

Someone who understands electronics enough to design circuit and schematic capture. I will need someone to transfer my schematic from a pdf to Altium or EagleCAD. I do not have time to do it myself. Job will require you to not only to draw schematic in a pcb software, but also create footprint of components that are not already in an existing library and detect any errors. Skills needed are knowledge of circuit design, layout design, and electronics in general. I will have schematic, BOM, and datasheets for completion of job. Additional key words: STM32, component selection, power and signal integrity, embedded hardware, firmware, integrated circuit, Lipo battery management IC, battery charging IC, IMU, wifi module, motor controller, video processing. The perfect candidate can easily transcribe schematic over to pcb design software and layout according to datasheet recommendations, but also suggest ways to reduce BOM, reduce PCB real estate, suggest components that may work better, etc. I need a team player who can stick around until prototype comes to life.

I am interested in having a circuit board and layout based on the Rasp Pi III 64 bit. This project will produce a schematic capture and a circuit board layout . We would prefer either using Eagle CAD or McCAD for both. The basics of the design is to include an on board power regulator excepting no less than 24 VDC supplying: 3VDC at no less than 500mA 5VDC with no less than 1.5 A 24 VDC with no less than 4A Other aspects of importance: 2 8 bit IO ports A & B 2 USB 3.0 ports GPS WiFi Bluetooth 100 Mb TCP-IP (TCP/UDP) - 1Gb would be preferred I2C port 2 Gb on board memory or memory slot to enable maximum allowed memory expansion Camera interface (CSI) Display interface (DSI) Micro SD card slot push-pull

Hi, I am looking for someone to create the shell or basics of a DIY project for me. I am looking for suggestions and then creation/implementation. Essentially I want a sort of microcontroller to control a 6x5 LEDs. I do not want to use one of those square matricies online, but independent LED's so I have more flexibility with where I put them. Any individual light or groups of lights should be controlled and changed by pressing a button(s) on a mobile or web app. I am looking for suggestions on the parts (i.e. Arduino vs Raspberry PI, shift registers, counters, resistors, etc), then once agreed design and creation. The web or mobile app can be very basic and simple in order to test the device. Thanks!

Hello Have you worked with GSM Module and any of the following boards (Arduino, Raspberry Pi) or controllers (8051, AVR, PIC, ARM) ? My project requirement is to develop - unique, original tutorials like - http://www.circuitstoday.com/gas-leakage-detector-using-arduino-with-sms-alert My List of Tutorials to be Developed is given below. You can pick the Topic Ideas your are confident with (and has access to the right components to implement the project) and reply me. My requirements are:- 1. 1000 to 1500 words original write up (the format is as shown in CircuitsToday link) 2. Original Circuit Diagram - designed or improvised by yourself 3. Photographs of practical circuit implementation 4. A short video - explaining the working 5. Program/Code - Originally written by you - with explanation Note 1:- Anyone applying should have very good Written English Skills. Note 2:- All contents (write up, circuit diagram, program/code, photograph & video) should be originally developed by you. We will definitely reject if you dont follow this! Note 3:- Please quote with your rate (fixed price) for developing a single tutorial based on requirements. I have posted the job as 'Pay by Hour' but please dont quote hourly rate. Instead quote the rate of a Single Tutorial. List of Tutorials to be Developed Interface GSM Module to PC - send and receive SMS Interface GSM module to AVR, PIC, Raspberry Pi , ARM GSM Based Intruder Alert GSM based AC Appliance Control SMS Based Security System GSM GPS based Vehicle Tracking System GSM - CDMA - Difference AT Commands - a Complete Guide GSM Based Home Automation Make Call and Receive Call using GSM Module Wireless Notice Board Using GSM Module Wireless Electricity Meter Reading using GSM Module
