Bluetooth Module
A ultra low noise power supply for use with Eurorack Modular Synthesizers
This is a prototype, to be much more compact later. Using PIC chip, a 900 mhz transceiver and a Bluetooth chip. Will convert a proprietary 900 mhz protolcol to bluetooth for smartphone app.
It is a high stability 10 MHz tunable reference clock for MIMO receiver. The clock can be tuned via USB or SPI interface with 0.01ppb precision

7INCH CORE REVISION
7" Core Development
I am designing a professional portable audio mixer recoder with some major rethinking going into how its built and used.
It is used as a microntroller based motor controller. Additionally, analog signals are showed by 7segment display
Headphone Amplifier Board for Hifi Sound using OPAmp and Buffers
This PCB is to make a Demultiplexe 1:2 with 1862 inputs, Each PCB have 96 input so it is necessary 20 PCB for the project. It have an external switching that select with output is activated.
The project includes two PCB board: 1. PCB CPU includes: microcontroller ATMega328PU, Ethernet-SPI controller ENC28J60 / SS 3.3V power supply, Two RJ-45 connectors and a transformer POE indicati...
