    I am looking to establish a long-term relationship with an electrical engineer with embedded design experience for several projects. The initial project is an electronic device that embodies the following sensors/capabilities:Heart Rate - Electrocardiogram (ECG/EKG) + Respiration3 or 6 axis Accelerometer - Motion and gesture recognitionTemperature SensorOLED Display Bluetooth Low Energy (BLE)Wireless Access Point/Gateway to transfer sensor information to cloud for evaluation/illustration/etc. If the engineer believes it is possible to incorporate a GPS without suffering too much battery life, then GPS capability would be great, too. If the engineer believes it is possible to incorporate wireless charging or actually motion charging (preferred), then that would be great, too. There is at least 3 other projects which incorporate the sensors above in various other fashions. Please send me a private message with your thoughts/estimates/questions/concerns and ideas. Additional information can be provided to you at any time.

    I need someone to design an Analog-Digital converter for automobile ultrasound parking sensors.I have installed a standard ultrasound parking sensor kit on my car.The device is similar to the one shown on the following link: ultrasound sensors get a lot of noise when I turn on my headlights or run other electronic devices in the car. I have tried everything possible to remove the electrical noise but I have not been successful. I am also unable to replace the sensors because they are painted with the bumper, and if I try to change them I risk damaging the paint on my bumper.I would like for someone to design an Analog-Digital converter that would attach to the 2-wires coming out of the back of EACH sensor. There are a total of 4 sensors on the bumper. The Analog-Digital converter should convert the analog signal from each ultrasound sensor into a digital signal that will not be susceptible to electrical noise in the car.I would also need you to design a receiver that would receive the digital signal from the 4 sensors, and convert it to be displayed in the digital display that comes with the parking sensor kit (see the link I provided earlier).I will send you 1 complete parking sensor kit (similar to the one shown on the link I provided earlier). The kit will include 4 sensors, the analog receiver, and the display. You should use the 4 sensors and the display from the kit. We will replace the analog receiver with your digital receiver.Your bid should include the cost of design, building 4 Analog-Digital converters, and making 1 Digital Receiver. The parts you build can be large if needed.Once you have tested the device and everything works well, I would need you to mail it to me in Los Angeles (the cost of shipping should be included in your bid for this project). Once I test it on my vehicle’s parking sensors and everything works well, only then I will release the payment to you.At the end you must also provide me everything I need for making additional devices, including: Schematics, Gerber files, Parts List, Detailed instructions for assembling the device, and detailed instructions on how to program the device.You must use electronic parts readily available on www.mouser.comYou must also make the device to be programmable using the microchip pickit2 programmer (this is the programmer that I have).Please let me know if you have any other questions.

    I need a circuit diagram and list of parts for a portable, battery powered device which when connected to a load of varying resistance gives a 40 Hz positive square pulse, with each pulse lasting 100us and having a fixed peak of 0.5 amps.The device needs to be able to handle a load of up to 2000ohms. If the load exceeds this resistance and the device cannot supply 0.5 amps, it must continue to supply current rather than shut off. The device will be operated for short bursts of 5 seconds or less, and will be used infrequently.

    Need: I require a USB device that accepts usb input device, and allows me to remap specific keys to a different characters.Example: When a user types the 5 key, the 5 key will output a "j" in the user"s operating system.Usage Case: I can plug in a usb numpad, and remap specific keys to different characters. Software packages do exists that have this functionality, but I want a hardware solution. Working Example: Here is a link to a forum topic which contains instructions for the device I need: http:// need a service provider with experience building teensy hardware components to build (or show me a comparable product) a usb to usb keyboard remapping device. Steps: I will select SPI will release initial milestone funds to SP for purchasing components SP will purchase components SP will build and test deviceSP will ship finished hardware to me. I will release remaining funds Skills required: Be able to complete task based on forum post. Be able to solder and complete arduino/teensy usb devicePlease Note: I created this posting because I have searched extensively for a suitable product, but did not find any devices that matched my requirement.If you have encountered an existing device that fulfills my requirements, let me know. I will accept you as the provider and compensate you for the referral.Summary:Need usb to usb keyboard remapping deviceI will pay for partsNeed SP to assemble them. Let me know if this exists.

    Our team needs to collect data for machine learning. We need a battery powered portable device capable of logging data from sensors to a microSD memory card, controlling two small motors, and enumerating as a USB thumb drive displaying log files when connected to PC.We need schematic design, BoM selection, board layout, and software development. The device will include gyroscope and accelerometer data, as well as audio recording. The device has two outputs, controlling low wattage (3-5W) motors. If your team can provide a complete schematic in EAGLE, we can do the board layout.A detailed statement of work (Word document) is available for interested candidates. We are looking to start immediately, but are budget-conscious (our company is un-funded, so as much as we want to pay you a lot, we can"t).
