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!

Looking for a person that can design a joystick that can control two motors via bluetooth. This means doing the circuitry/programming aswell as designing the joystick itself. I do however a PS3 joystick that controls two motors via bluetooth, so you might be able to reuse some of that code. Im imagining a product looking something like the "Zeemote" joystick, which you can google.

This is a very basic hardware which I want to build. And I'm pretty sure anybody with correct knowledge can build it very easily. I want to make router like device with my own web interface (webinterface is the configuration page of router which is normaly accessable at I don't want to use raspberry pi or arduino, i just want to go with same technology we have in router's. I have 1 programme built in 2 languages (shell and php). I just want to run that programme on the hardware. About the hardware: Device will have one LAN port and wifi-receiver for internet connectivity (hardware will get internet access through these interfaces). And run my programme in particular interval of time again and again in loop. Please quote fixed price for this job.

Looking for an experienced RF engineer capable of PCB design (preferably on ADS or Altium). Currently we have a PCB design that accommodates a state-of-the-art 122 pin chip. However, the current design relies on external SMA connections to connect to two hybrid couplers and 2 3db couplers. I need to have these couplers on the transmission lines of my PCB and shrink the size of the board. Also, to achieve this goal, we need to replace a D-sub with a micro-D connector.

We are designing some remote wireless sensor devices for various markets including consumer and business customers. These sensors could monitor a variety of inputs including temperature, humidity, motion, AC current, water flow. The sensors will provide Web feedback and or remote control to customers by E-mail, text messages, web pages and Smart Phone Apps. The sensors may also switch off and on local devices such as lights, pumps or dry contact switches. We are looking for suggestions for hardware devices to provide the Client end and also programming both the devices and the customer interface side ie: Web page, Text messages, smart phone Apps. Please provide your your suggested hardware recommendations and quote your time to build a working prototype and a customer interface. Follow on work will depend on the success for the 1st working prototype.

I am looking to power several devices using one power source rather than one power adapter per device (which in case of digital cameras seems to be the only option). I need a schematic so I can build a PCB which would allow me to plug in several (e.g. up to 6) devices at once but making sure I don't blow up anything if not all outputs are used (like my current setup, which obviously failed). Possible specs are 6 outputs of 8VDC @ 2A each, protected against over-voltage and over-current to protect camera equipment. Current cameras I'm using are Nikon D3300, in case you need to look up existing power supplies or battery solutions. Also perhaps Nikon D810. Depending on the complexity I may also have you design the PCB.
