I need schematics and layout (in Altium Designer) for two custom PCBs: 1. A simple, small PCB that holds an OVM9724-RYDA camera module. This board should contain all requisite power conditioning, voltage regulation, etc. to run the OVT system. It should output (via a small cable plug, TBD) all requisite I/O (e.g. power, clock, SCCB, and MIPI). 2. A converter PCB that interfaces with the first bo...

Good afternoon! I am Herman Remy, a 16 year old in charge of a startup called Walker Industries. I'm currently developing a pair of XR glasses, but need a custom computer board made for it. I'm looking for something similar to the Intel Compute Stick but with much more RAM and a bit more graphical power in what should still be a relatively small size factor. A more powerful CPU is also a...

I am looking for a PCB designer who can design the schematic and then do the PCB designing if possible simulate the results looking for an expert in the field My project is I am trying to design a resistance Decade box

The design is a 32x48 PLCC2 LED matrix with 1:1 driving and a 4.4mm horizontal x 5,6mm vertical Pixel pitch. Attached are views of top and bottom side. As the display board has to be stackable in both directions, the overall dimensions have to be slightly less than 140.8mm horizontal by 268.8mm vertical except for the tabs on top and bottom edges that will be used only for manufacturing and will ...

I build musical instruments. We build one instrument with a very high frequency that is annoying to practice, though it is used extensively in orchestral performance. We want to make it more accessible to the general playing population. My idea is to make headphones that drop the pitch of the instrument by FFT an octave lower. I wonder if it is possible to modify a pair of noise cancelling headpho...
