    We require a development ("breakout") board for CSR BlueCore6-ROM chip. The PCB will be designed to expose all pins onto header(s) to facilitate programming and interfacing. The PCB will also include any required peripherals (osc/clock, USB-to-SPI programming/debugging interface, etc). Please have a good working knowledge of CSR's BlueCore6 products and programming interface. Deliverables: All design files, schematics, layout, BoM and gerber files. Engineer/designer will be responsible to oversee technical requirements for successful production of physical ...

    The system is concerned with the design and construction of a microcontroller based automatic gate. The microcontroller to be used is the Atmel AT89C52. It is to be programmed for the automatic opening and closing of the gate through infrared sensory actions. The microcontroller based system monitors and controls the opening and closing of a gate. It makes use of a microcontroller that accepts data value from an interfacing circuit and then makes an instant decision. When the system senses ...

    Get a PIC18LF45K50 (or PIC18F45K50). Connect it to a PAN1323 module. Achieve 4096 Bytes per second data transmission in Bluetooth 3.0 (not BLE), using the HID profile in sniff mode, OR another protocol supported by iOS without the need to enter the MFi program (http://support.apple.com/kb/ht3647). You transmit to an android and iphone with a small test app to verify throughput. The entire circuit must consume less than 5mA. I offer 500$ for the android ...

    Hello, I need BLE beacons developed similar to this: http://estimote.com/ or Qualcomm Gimbal. Beacons should be detectable by BLE-enabled smartphone, have enough battery for couple month and a nice case. Please DO NOT respond without time and cost estimate. Optional: include production cost estimate. NOTE that my budget is not accurate since I don't know how much can it cost.

    We wish to produce an "Own Brand" printed smart card to emulate the one produced by the original equipment manufacturer. This card is inserted into a performance monitor fitted to a piece of fitness equipment and records the workout data for up to five discrete users. In essence it is a memory card, but the problem is to reverse engineer the proprietary coding used to record data. I obviously don't want to do anything illegal, nor spend unlimited time ...
