hi-3 

Hi-3, is a hi-5, but only using the 3 fingers, as used in a scout/brownie promise.
You can only do a hi-3 if you were once a beaver, cub, scout, rainbow, brownie, or guide.

Mark: Hey you, that was an amazing shot!
Ems: Thanks.
Mark: Lets hi-3!
Ems: hi-3!

Hi3519E 

The Hi3518E is a IP-Cam SOC that has a 440mhz arm processor, this chip may be used in spy cameras due to having an ISP, it can handle to 2 megapixels when encoding in h264, also 512mb (16 bit) ddr2 ram and runs linux.

I will change the firmware of the ‘Hi3519E’ to run doom.
