Engineering of a biometric (fingerprint) module incorporating wifi and bluetooth to develop a smart device for use in the consumer and commercial healthcare markets. The design should take advantage of IOT and be able to communicate via wifi over cloud to application(s) on smartphone or tablet. The communication between the phone app and the product will be bi-directional.

We are looking for Hardware Designer who can design the PCB and select suitable components to match the detailed requirement and functionality, the aim is to replicate the Garmin 1000 PFD & Audio Panel. The design requires a routing/layout of tracks for the switches and knobs and interface with the controller. The circuit would require converting the switches and button presses to USB interface utilizing either the Leo bodnar BBI 32 or a separate circuit all together with a driver. The Display screen sourced to match the size of the actual unit should have a VGA interface. A second revision option should have the capability to install an Rpi to drive the display and in interface the input buttons. There should also be an option to place SMD LEDs to provide for Backlighting capability and have easy interface/connectors to replace any key during maintenance activities.

circuit board to measure air pressure. and an LCD display circuit chould be very small in size. air pressure uo to 9 bars. after completing the project circuit and LCD and all related parts Hardware and software and code and diagrams should be shipped to me LCD should display consumption level, when it should be empty, I think this is all simple formulas. My Budget is in the $100 range includes shipping, part prices, unless i can approve, if you are not interested please withdraw from this project thanks

"I have a dream..." I want to build an electronic board for a smart home project. I need digital inputs (for buttons, dry-contact), digital relay outputs (230V, 16A), and some basic logic (like a way to communicate with the board via MODBUS registers for example, and get inputs when button pressed and change register value to make a light ON or OFF). If you know about logic, electronics, PCB design, etc. - I'd happy to hear your insights about making such a board. Also, I still don't have an idea of how can we design that board on your place, and have it working at last - on my place. I'd be glad to hear good ideas for that. (designing it, making it, putting on all components, and seeing it at work..) Thanks.

I'm looking to make a PWM constant current regulator with a capacitive touch input. I need someone that can lay the board out in Dip Trace. Free versions are available. I have a paid version I can load in to. I need someone that is familiar with EMI and PWM-ing. The restraints are very narrow layout. I have the constant current regulator picked out. When input is hit for a long touch board will dim up or down. A short quick touch will turn light on and off. I need someone to design the Microchip circuit using a PIC with a built in capacitive touch circuit. We will specify which one. We will provide capcitive antennae. We will provide boards an components. You need to do schematic, pcb layout, PIC programming, have your own PIC programmer, and tweak components and program for correct function.

I need a circuit board designed for automotive accessories to be easily added to vehicles. The circuit board will need to have a common power input and common ground, 6 relays with switchable power inputs, screw terminal in and outputs for the relay switching and outputs. The board is to be approx 150-200mm long x 100mm wide roughly. Each power input will need to be fused.

Hi there, I am looking for a skilled PCB designer to design a custom HDMI driver for 21.5inch LCD panel. The Board must contain (1)one HDMI port and RCA A/V port as well as connections to display and controller board. The picture attached shows the current HDMI driver being used. The customer PCB should be able to control brightness, contrast, etc. Please respond if you have the necessary experience. Thank you.

I want an electronic circuit which can communicate with a smart phone through bluetooth interface. This should include a software install-able in smart phone( both androids and windows) which you can switch on phone bluetooth through it, send signal to the circuit when there is incoming or outgoing call, then the circuit perform some switching. kindly send me a quotation soonest possible.

I have attached a high level block diagram for what components are needed on the PCB. I am looking for a small design, about 1" by 1" that has a nordic semiconductor's NRF51822 SOC + an accelerometer and debug port. There are reference schematics for both accelerometer and the BLE chip online. There are some designs online that have same accelerometer if you are looking for inspiration for the design. One such design is here. http://get.openbeacon.org/device.html This one does not use a PCB antenna, LED and button that I want.

Hello, Please visit these 2 URLs. 1) http://www.instructables.com/id/ARDUINO-ENERGY-METER/ 2) http://www.homemade-circuits.com/2013/03/simple-dc-ups-circuit-for-modemrouter.html Your job is to mix these 2 circuits. Changes you have to make: For link 1: use arduino nano instead of arduino uno. I dont want to use ethernet shield. All the values have to be put in csv file and sent through usb port to computer. For link 2: You need to optimize this circuit to 12V/5amp DC from solar panel input(controller will be present). Now the arduino nano present in link 1 have to measure the voltage,amp and wh for link 2 circuit: i) electricity used to charge the battery ii) electricity supply in case of power failure from mains (No solar input) iii) electricity supply directly to modem (from solar controller to modem) The link 1 meter should send the values of these 3 cases in every 1 sec. You need to send me all the required parts (in detail with the part number), arduino...
