You sure can. Just stick it on a cable with an inline power switch.

But at the moment it only takes a 2s battery. This is due to the step up 9v regulator powering the goggles. If this was replace with a S10V3F9 then you could use up to 4s, but I have not tested this.

Thanks for answer
I rebuild diagram for project with button power by Pin SCK attiny85. However , attiny85 with 4k flash maybe no problem ?

Yep the flash is pretty much full at the moment. You'll need to use a non software on off button.

[jonathan2018]

i m reading source code to understand and modifi from your code . maybe lost times for me to do it work

[JyeSmith]

Any reason you need a software power button?

[jonathan2018]

reason : i want to ON/OFF power for FS instead plug in or remove Jack .Fs have not Switch power .
Display infor volt ,ampe ...on LCD is advantage and combined feature sofware power is so good.

Orginal your project have all infor on LCD OLED .

@skaman82 I came across yours when I started mine... This is how I found the 9v reg to use 😉
