EBC Bilateral Brain Stimulator

Cam files (gerbers and Excellon txt) are uploaded in Github repository

In the repository github I upload some photos of how to make the box in the word document entitled "Building the box.docx"

In this link it's the altium cad files compressed of the design version of "PIC (PIC version in CAD altium)" and Arduino version "(EBC v02 (ARDUINO version in CAD altium)"

Thanks to "Anonymousmst" and his project "The fsociety Keyboard" I have discovered the WS2812 LEDs. I was used to working with the old shift register 4094.

Thanks "Anonymousmst", this component has simplified me much programming work.

A lso Adaftuit has a library for use with Arduino, so get to work and here is the result.

With this video you can see the visual estimulator operation (LED bar) in two of its bilateral stimulation mode with white, green and blue colors.

The operating modes are selected with 6 keys on the infrared remote control and the video looks like each selected

Multilayer PCB (up to 8 layers) with plated-through holes (and vias) at home.

PCBs make prototypes at home, it has indisputable advantages of cost savings and time.

The challenge is to do with the resolution (multilayer) and reliability of entrusting them to an external company.

This problem come by suffering all hackers in each new project.

This project (EBC Bilateral Brain stimulator) equipment for EMDR stood to devote to solve this problem that has taken me over a year.

I can now say that I have been satisfactorily resolved and I can make prototypes up to 8 layers with metallized tracks and drills step.

I show you a simple example at this link

On this site are the sources in the workspace in MPLAB (programed in mplab-C18) from Microchip and the circuit in ISIS (Proteus v8 of Lab Center) for simulation.

Only provides the code for the simulation of visual stimulator. When the project progresses I will publish the rest of the code.

Part list (BOM) of the circuits that make up the design.

This site is the BOM of my design (https://github.com/djimelec/EBC-Bilateral-Brain-Stimulator/blob/master/BOM%20of%20EBC%20design.rar) .

Now I will present the realization of the envelopes of the CPU and keyboard.

There have been 3 different designs and photos of those who have done "by hand" and sketches of their design are presented.

In making these prototypes used to make silicone molds to make boxes with polyester resin
