I am designing a solar powered light product, and would like your expertise to further development. It needs to be able to fully charge during the day by an inbuilt PV panel, and then run on that energy throughout the night. It should also be networkable through bluetooth and WiFi. The device should have a clear shell, illuminating light in all directions (similar to a light bulb), where the only exception is the solar panel mounted on top, and all electronics must be hidden inside of this facade. I am looking for both, design as well as clever electronics solutions, for this project. I have a general list of components to be used, and need PCB design and final prototype assembly and testing.

The project is for a small consumer product that will use motion control to activate a light. The heart of the project is a Printed Circuit Board with a Microcontroller (MCU) and an Accelerometer (ACCEL). The device will need to be configured to run on the lowest power possible, with the device going into low power, or sleep mode in-between each MCU cycle. The device will run on 3V power using a re-chargeable Lithium Ion battery. The PCB will need a charging circuit, a low voltage cutoff circuit, a USB plugin connector that can communicate to the MCU and recharge the battery. The electrical engineering requirements are as follows: -Finalize decision on which MCU to use (current proposed MCU is PIC24FJ64GB002) -Design charging circuit and low voltage cutoff circuit -Capture and layout PCB with, charging circuit, low voltage cutoff circuit, Micro USB connector, low battery LED, power connection, mode switching button, necessary load switching circuits, and connection to an on / of...

Hello, I am looking for a micro switch or sensor based seat belt kind of electronic device. Scenario: This belt will be ON the chair... where a person sits on it. If that person leaves the seat, this device needs to wait for 5 minutes, and if he don't come back and sit on the chair? it should start giving some small beeps are some sounds to bring him back to the seat. The delay of 5 minutes is allowing the person to go and get a coffee or some quick things to do, away from his seat. Few requirements: ? It should be very small and compact micro switches / sensors. (as the person will sit on them, he should still feel the 'almost' natural comfort) ? If required.. The circuit or beeping things can be extended and keep bit far/ under the seat. ? The time delay should be adjustable to give freedom to the user to choose the delay to alert him to come back to the seat. ? Beep /sounds should be pleasant, cool and if possible, multiple musical tones where user can change! (This feature ...

Develop Software in JAVA to interact with PCB(hardware). Modify or create schematics and PCB from existing schematics. Write firmware for PCB. PCB's will communicate with the JAVA program residing on a PC via CAN network. Software will be able to set parameters in PCB's and record data sent from PCB's. Software will also provide a GUI for the end users. Software must include reporting features(to be defined later) PCB's will have 4 user inputs(switch inputs), 4 outputs(to operate solenoids), and 2 analog inputs for measuring resistance of fluid between to electrodes. The PCB's will communicate with the software VIA CAN network at 256 kbs. Suggest using CAN open standards. Also require a usb to CAN adapter(dongle) using ftdi chips for the USB side and preferably the same mcu as used on the PCB's wich is currently Atmel Candidates should be experienced with CAN Open standards and protocols, PCB hardware design, Firmware, & Java.

The design/fabrication of a simple, approximately 70mm in diameter, round printed circuit board for 12v LED light. Board will require pos/neg connectors of some kind located around the outer edge at 45deg. intervals -- 8 pairs of connectors total -- and will include an LED component in the middle. The connectors will be used for the simple attachment/detachment of wire leads. Also will need to design/specify/fabricate the wire leads -- 2 conductor, 20-24 gauge, with terminations to attach to printed circuit board. Terminations need to be as small as possible.
