    Electrical Circuit problem 6 days left
    VERIFIED

    Hi, I have built a circuit and there seems to be a problem with it. I am out of ideas what the problem is. Can you watch the videolink where I describe the issue and have a look at the drawing. If you know why this problem happens, I want to hear from you. The job is completed once you told me what the problem is, so it will be a "one msg" job :-) Thank You

    The project is to design a PCB layout with one type of connector which will connect to a different type of connector with approximately 100 pins. As there are a couple of variations in pinout there will need to be some jumpers or solder bridges to vary the functionality of the pin. A very small number of electronic components will be needed for functionality on the board.

    The block has to be able to transform infrared radiation, around 940 nm, to electrical output of 3-4 V, 40 mW or more. Requirements: Block circuit is self-powered from the abovementioned infrared energy source (without additional battery, etc). Block has to be restricted to size less than 1 square cm, and less than 2-3 mm height. Block components have to be common/accessible/inexpensive, preferably of SMD type. Possible solution is "Joule thief" schema with PIN Photodiode. However, other solutions are welcomed. Project's result has to be presented as EasyEDA compatible schematic and PCB, with video proof of its functioning.

    We currently have a working PCB (see image) which needs to be updated. We must add a USB connector and InfraRed transmitter/receiver. The IR circuit is very simple and will be entirely provided. The work is to be done in Altium. The schematics and layout must be updated and parts created if needed, as we want to extract the BOM from the Altium design. More details will be provided to selected candidates. This may lead to many more projects with us.
