Launch Button

Last crawled date: 4 years, 2 months ago

It is "rocket-launch-style" button. I use it for Raspberry Pi On/Off: https://youtu.be/Sorz_R3qYB8 https://youtu.be/5vO_z-kapwE
The idea was to use small button (I do not kave other) but protect it from falling thing and accidental push.
I have not found something here so made mine. I think it is smalles possible, but you are welcome to get .scad file and play with it (or use https://github.com/sanja-byelkin/LaunchButton )
Here used 6x6mm buton (probably most frequently used button :) ).
ATTENTION! if you put the button in place inside the boy it will be difficult (probably impossible) to get it back without destroying something. So you better solder all wires and then push it in its place.
Recipe for setting up Raspberry button found here: https://www.stderr.nl/Blog/Hardware/RaspberryPi/PowerButton.html . It short you put the button between GND and GPIO3 and put following line in /boot/config.txt:
dtoverlay=gpio-shutdown,gpio_pin=3
I "glued" my button with double sided tape on my Raspberry Pi box.
