I am interested in having a circuit board and layout based on the Rasp Pi III 64 bit. This project will produce a schematic capture and a circuit board layout . We would prefer either using Eagle CAD or McCAD for both. The basics of the design is to include an on board power regulator excepting no less than 24 VDC supplying: 3VDC at no less than 500mA 5VDC with no less than 1.5 A 24 VDC with no less than 4A Other aspects of importance: 2 8 bit IO ports A & B 2 USB 3.0 ports GPS WiFi Bluetooth 100 Mb TCP-IP (TCP/UDP) - 1Gb would be preferred I2C port 2 Gb on board memory or memory slot to enable maximum allowed memory expansion Camera interface (CSI) Display interface (DSI) Micro SD card slot push-pull

Hi, I am looking for someone to create the shell or basics of a DIY project for me. I am looking for suggestions and then creation/implementation. Essentially I want a sort of microcontroller to control a 6x5 LEDs. I do not want to use one of those square matricies online, but independent LED's so I have more flexibility with where I put them. Any individual light or groups of lights should be controlled and changed by pressing a button(s) on a mobile or web app. I am looking for suggestions on the parts (i.e. Arduino vs Raspberry PI, shift registers, counters, resistors, etc), then once agreed design and creation. The web or mobile app can be very basic and simple in order to test the device. Thanks!

I am interested in updating and adding to an existing medical device known as the NeuRx Diaphragmatic Pacing System (DPS). This system allows quadriplegics and persons with ALS to breathe independently of conventional mechanical ventilation. The DPS uses a fixed number of pulses per minute, which works well, but does not allow the user to experience fluid control over his or her speech pattern. My intent is to reengineer the electronic control box that regulates varying inputs and to incorporate a pressure sensor into it. This will allow the user to draw breaths as needed, rather than waiting for the next pulse. I am doing this for personal use only and have no plans or intent to bring thing to market.
