EEG-Cap

Its a EEG-Cap build based on the following Project:

Blog post: https://beckystern.com/2015/07/01/eeg-costume-cap/

Many thanks to the creators of the base.

Why this repo?

I would try to build it too and made probably some enhancements.

I would document here my work too.

Addons in idea:

Add magnets to the hut disign, to enhance the possebilitys of adding and removing the whole hut for wasching it.

Add later New Nobs SLA Printed ? or a combination of FFF and SLA

(dont go too crazy.. sorry but probably shuld i )

What do i Need to find.

for the Electronics:

45 of 74 leds used out of led strype.

I bough this Offer and had some old spare arround.

(Had LED strypes at my place)

Silicone Wire (Black and White)

bought 20 AWG of this offering Offer

for next build get a wire that is thinner like 30 AWG its horible to solder it like it is !!!

in both colors (Black and White)

I used Wled and a seed studio esp32-c3

• how to use buttons with that?

• how to use a Oled With that?

I would like to use something Micro or cyircut pyton drivan to dump a python object directly against my head.

Neodymium Magnets. 74 +- bought 100 of 5*1 mm magnets from this Offer

for the Cap:

Sawing:

I Produced the Cap up on the Ideas up on the sawing patterns of the original pattern.

My Head is taller than her, therfore I schuld scale the pattern up and some scaling effects appered.

therefore i redrafted the pattern.

how to fit the two sides together ?

I used pressed buttens injected into Jeans fabric. added upon the original Neopren sheet.

I used Zic Zag stich for the sawings between the Neopren peaces.

And to the jeans fabric.

LEDs:

I used Rests of multible old Led Stripes. In the next build use round PCBs like menschend in the original tutoril.

It would be mutch more fun.

if you use leds from diffrent stripes, be aware that they all speak the same one wire Protocol and the color arangement is stadard.

if you dont't you will be lucky the time you configure the firmware.

to do Soldering led Beams:

I have a taller Head therefore should i use a diffrend spaceing and arangement.

I decided to use a space of 30mm between the led outlines...

pattern should hopfully aranged like that:

Idea:           Original:
R4 -> 5         R4 -> 6
R3 -> 7         R3 -> 7
R2 -> 9         R2 -> 8
R1 -> 9         R1 -> 9
L4 -> 9         L4 -> 9
L3 -> 9         L3 -> 8
L2 -> 7         L2 -> 7
L1 -> 5         L1 -> 6

what I would do would be decided at practical test

To do:

• Solder The Stripes

Do like To use a level Shifter but is still not nesseserry.

Would like to split the hut into multible circits like

L1, L2  to  a pin on mc 
L3, L4  to  a pin on mc
R1, R2  to  a pin on mc
R3, R4  to  a pin on mc

to reduce risc of failiure at a party.
