Power board
About the Power board
Power board is an open source PCB design by rosalyntg, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 113 × 86 mm, with 80 components from 41 distinct parts.
Other key parts include the AP62300TWU-7, MCP4018T-104E/LTY, AZ34063UMTR-G1, MCP3021A0T-E/OT and TS507CLT. By type, the board carries 33 capacitors, 14 resistors, 10 diodes, 9 ICs, 6 inductors and 4 connectors.

Hobby Ultrasound Machine
This repository contains the PCB design files, FPGA firmware files, and host software for a hobby 8 channel ultrasound system. It can do phased array operation. Here's an example of the pulse in my forearm:
Picture of the functioning ultrasound system:
The parts of the ultrasound consist of: - The probe, which is a Acuvision 4V1c probe bought off ebay - As far as I can tell, it has 112 elements. I think a bunch of them are broken for this unit, so I've atttempted to work around as best as possible - The power board - This provides a variable voltage positive and negative rails for the…
