Several years ago, I bought a decommissioned mil-spec radiation meter. It had a busted LCD, so I ended up reverse engineering the circuitry and replacing it.

Well, I accidentally grabbed a module with red backlight... and ended up with this sinister "we're all gonna die" vibe.

Also makes for a great TV/movie prop!

@lcamtuf when building a doom-o-meter / "how fucked are we?"-meter one shouldn't half-ass it. Excellent work.

@lcamtuf does the scale go beyond 3.6 R/h?

@lcamtuf

I was going to say "you need a programmable RGB backlight", but nah, this is perfect. Keep up the good work!

v2: Get a new LCD with a color changing backlight and see if you can add something to change the backlight color from green to blue to yellow to orange to red as appropriate.

@lcamtuf That's a highly esteemed deed that should be commemorated! Put it in a place of honor.

@lcamtuf any chance you have a write up on your RE of the circuitry? Would be helpful as I wouldn’t mind picking up one of these.

@lcamtuf Did you die, though?
