Brief: to develop a working prototype MIDI instrument that controls computer music software. The device will use a microcontroller and will consist of a printed circuit board. The prototype will involve developing the hardware and the software. Using off the shelf components and existing open source code. Requirements: ● Preferably works with an iOS device to operate GarageBand’s virtual instruments ● Velocity sensitive buttons ● A matrix of 28 buttons, which are velocity sensitive and trigger MIDI notes. ● LEDs will light up when buttons are pressed ● The LEDs which light up the buttons need to be multicolor LEDs that light up according to the note. ● Powered by 240V mains You will need to design a working prototype. The final prototype will use an existing microcontroller (Arduino or rasberry Pi) and/or a full printed circuit board. Excellent english skills are a must

There are 3 elements to this contract 1) $200 to any one who can find and source this item if it is already manufactured. 2) $300 - $600 to adapt or build from scratch the device (with all documentation). I will include any expenses that are needed (purchase of items etc) 3) To develop an app to work with the above project. $500 - $750 This will be version 1 of 2 versions of this project. The concept I need a transmitter (with 6 settings) As small and lightweight as possible. The settings are set manually or by app/bluetooth......to trigger a different "signal" to the receiver. I need a receiver/transmitter, that is attached to a RGB led strip. That once the transmitter above goes within 2 meter, it lights up ...corresponding with the setting on the transmitter. So if the transmitter is in position 1 the receiver/transmitter lights up blue, 2 = red, 3 = green etc.... If different receivers are needed for each colour...that may be an option.(but not preferred) The transmitter will be moving , but the receiver will be stationary. The transmitter will move quickly (running or on a bicycle), so it needs to trigger quickly. Power to be internal for the transmitter, but external due to LEDs on receiver. The app...Each transmitter (colour) I need to assign assign a name to (like Bob on his bike) .once the light is triggered in the receiver/transmitter....a signal would be sent to the app to say its been triggered, by Bob. There will be a number of these triggers (or gates for time trials)...So each transmitter must be able to send a different trigger (maybe a gps as well), with a time between the first trigger , the next, and so on. Any questions ask please. I dont mind, if someone wishes to just build the device as long as good documentation and access to the app developer is apparent, and in place.

We are looking for an experienced electrical engineer, who has great experience with sensors like: Accelerometers, Pulsrate, Temperatures etc.. Preferable all of these. These sensors will be added to a motherboard with bluetooth, wifi, GSM and GPS. All data should be available through an API. Battery lifetime is a key element to the prototype, size isn't at this point. We need a description of components and how it bundled plus a simple prototype which can send data to an API. We will off course pay for all the components that needs to bought in order to test,

I am looking for an experienced electrical engineer / hardware designer to design a PCB with the following specifications: Basically, the project can be seen like adding a Raspberry Pi 3 to an Arduino Mega 256 with added input and output handling of industrial compatible signals. The input section consists of 4x or 8x analog input of 24V DC as well as one or two power-based inputs of 0-20mA of the same voltage. Digital Inputs of 24V DC are also needed. All Inputs should be isolated from the inner circuit. The output section consists of 8x digital outputs which have 24V and are solid-state or relay based. In case of the latter the used relays should be capable of handling up to 230V AC at a moderate load. A different combination would be having 4x 24V solid state and 4x 230V relay based outputs. As mentioned above the unit will be used in industrial-like environments so it is highly required to isolate the i/o section from the inner circuit through some kind of protection circuit. All the I/Os should be connected to the ATmega2560. The ATmega itself will be connected to the Raspberry Pi over one of its UART. To provide Arduino compatibility the Arduino-typical automatic reset-circuit should be implemented as well. So basically it's based on the open source schematic from Arduino. The I/O section should also feature LED-based indicator whether a channel is set or not. Also very important, the UART, SPI and I2C should be carried over to a connector so that additional modules can connect to the board later on. The Raspberry Pi 3 will be plugged onto the board from the top and upside down. In the middle of the PCB there should be some connectors and screw-holes to match the footprint of the Raspberry Pi. The whole circuit should be integrated on a single PCB with a dimension of about 16x16cm. I can provide more detailed informations as well as some basic sketches of how I imagine the circuit or elements connected to each other. But I think that this information is enough to get an overview of the size of the project. Please feel free to ask any question!

Hi all, I am looking for a creative and hard worker freelancer. to design and implement attendance device with the following functions. 1- Touch screen. 2- RFID reader 3- Network interface The idea is that on the touch screen will be displayed 2 big buttons one green for login and one red for logout when he clicks on the login the whole screen will be green with hour on the top left and the employee will pass his card near the RFID reader then the device will send a request to a predefined server with the info of the card id and the date time and the type of action (login / or logout ) I thought it would be easier if we use Raspberry pi to be the main controller on this device. I will provide you with the designs for what I need in details later on

Stop Voleur is a connected wearable which prevent the loss and the theft of smartphones. Hung to a watch, a bracelet, a bag or a jacket, Stop Voleur is connected via Bluetooth to your smartphone and triggers an alarm as soon as it is spirited away from you. The further you are, the louder the alarm is. Thus, in case of theft, the robber is forced to give up the phone and leave shamefully. In the event of loss or omission, you are immediately notified by the alarm and just have to pick up your favorite item.
