I need a custom board designed for the Atmel SAMA5D4 that should be relatively straight forward. I would like for the design to be done in Eagle, but that isn't a firm requirement. The board will have these types of components: 1) LCD connector for a 720p display 2) 256 or 512 MB of DDR memory 3) NAND flash (for the boot loader, firmware, etc.) 4) SD Card for the OS, etc. 5) Various regulators and filters 6) A few I2C/SPI/UART sensors 7) One or two debug connectors I have a good idea of what I need and this project needs to be done fairly quickly.

Looking for a 12V DC motor control for a small 100W motor. Need a CPLD with LCD or LED Display The Display can indicate 2 Digit Count that shows time that allows motor to run for a specified time. Say Display =01 implies 15 seconds Display = 02 implies 30 seconds etc., Need a up count button and down count button to chose the correct value. Components needed : 1. Small 2 digit LED/LCD Display, 2. 100W DC motor, 3.110V to 12V Power Adapter, 4. Up button (can be simple push button) 5. Down button 6. CPLD You can breadboard it and I will get a PCB designed once the system is working. Get back to me for more specific details

I have a custom PCB based around the Freescale i.MX6 that needs to have simulation done on its DDR3 interface. Depending on how that goes there could be follow on with the eMMC and PCIe interfaces being simulated. Must be done in Altium and then the files passed back because we need to run the simulation in house on our Altium installation. The design files will not be allowed outside of the United States.

Need a circuit than can track a pencil or similar type line as a device moves along it and sends signals to two or four stepper/servo motors or other position controllers to keep the device in line by compensating for any drift within 6 mm (or more). The device consists of an inner and outer frame. The outer frame is for large movement. The inner frame is for precision movement. The outer frame moves horizontally, parallel to the line and is not electronically controlled. The inner frame holds the tracking unit. It is the tracking unit that adjusts while the outer frame is moving. If the outer frame begins to move out of the range of the inner tracking unit, an indicator comes on indicating the direction to move the outer range otherwise the inner frame adjusts automatically to maintain position. The inner unit can move via the servo motors or similar position controllers +/- 3 mm. This is the minimum acceptable range. Greater range is desired. Summary: Device tracks along a line Co...

I am looking to design an Android based device to run a custom OS for enterprise purposes. The high level block diagram is attached. Please submit rough proposals (time and rate) and we can share more specific requirements on the project design. Project description: I prefer to work with a group with simulation capabilities. Most of the initial work will be in a simulated environment to decrease cost of board spins. We have specific chip sets in mind, but will defer to more knowledgeable designers. This project is funded, but we need to better understand the design time before we set a cap on our spending. Hoping 2 man-months is reasonable. Prefer capped cost, but we understand the nature of our request and are open to a hourly rate. This tablet will not need to optimize power use, size, or processing capabilities as it will be wall mounted with access to permanent power (although short term battery backup would be a nice to have). We do not need design group to be able to f...

I want a laser trip wire PCB to be designed it should have a laser beam and LDR, When the laser beam is disturbed it must trigger an alarm, it must have out puts where the siren and lights in the house can be connected and one more thing is once the laser is tripped siren and lights must be on for 1 min. the circuit board must contain all the component in one board. it must be easy to produce, reliable and cheap i have attached a link for your reference but in the link the siren goes off once the disturbance stops. our board should keep the siren on for at least one minute   [obscured]  /watch?v=1HZQHcWTlOA&noredirect=1
