    PCB design 6 dias left

    Creation of a small PCB for charging and powering a single USB A port. What I would like to have designed for me is a PCB that enables charging of a 3.7v battery through USB C, and outputs power to something that can be soldered to a USB A IO. The USB A output will only be supplied power when a button is pressed, and power will stop being supplied after 5 minutes. The PCB will need to include battery protection, and deep discharge protection. In short, this PCB will be connected onto an already existing PCB, that should only receive power for 10 mins after the button is pressed.

    I have a concept drawing done in revit 2018.2 model for 4 storey building. I am trying to get pricing for Electrical and HVAC in order to get an idea for financing purposes. Unfortunately the subcontractors do not entertain quoting the project without a full set of engineering drawings. Given the fact that it is only a concept model (which will most definitely change when architects and engineer get involved), I cannot spend too much. Please specify number and type of drawings.

    I need to detect the number of rotations of a spinning magnet. I have measured the magnetic field strength oscillating around += 0.9 Gauss (see attachment). Most hall effect sensors with built in amplifiers and comparators don't have operating points in this range so I need to design one using an analog output hall effect sensor and op amp. However, I'm open to other design suggestions. Requirements: - Digital output indicating a rotation of the magnet - Low power (~50 uA @ 3.3v) - Minimal part count - Low cost part selection - SPICE simulation or some kind of verification of design Example design: Analog hall sensor (e.g. DRV5053) -> Amplifier -> Comparator with hysteresis (e.g. TLV320x) -> Digital output

We have all designs and firmware for our RF device completed, prototyped, and tested. The only part of the design we do not have yet is a 3D print file for the outer plastic housing. We are looking for an electronics manufacturer to produce our RF device for us. Small batches at first, but hopefully larger amounts as we increase sales of our product.
