IR LED

>not powerful enough

stick them in parallel with resistors until you have enough power

They don"t have enough luminosity. So do you know what could be done with low luminosity IR LED ?

>>1080446
short distance wireless comms

Do a TVB gone with it. It's simple to do and doesn't cost much if you use cheap ebay components.

Always wondered if enough of those could mess up traffic cameras or just cameras in general.
40kHz (methinks) is what the cameras modulate at.
Photoproof hat?

a big FU that can only be seen by traffic cameras?

I wanted to make this with them but the luminosity is way too low.

Most cameras have an IR filter.

Not security cameras, they have to film in the darkness.

True, but it's not a very good one. Interesting trick is to look at any IR remote using a camcorder or camera and watch the IR led. You can also do this to spot "night vision" cameras that rely on IR LEDs to see.

hook them up to AC instead of DC so they strobe at 60hz.

find a TV channel you want to watch, plug in 60hz strobing IR leds, give significant other TV remote because she doesn't want to watch your shitty show, quietly laugh to yourself as she complains remote doesn't work because the strobing IR leds are confusing the IR sensor on the TV.

everything should be fine unless the camera on her phone doesn't have an IR filter and she she figures out what that light is coming from.
