The discoloration is likely because blood got trapped between two pieces of skin. It will go away but itāll take a long time.

Your question made me curious so I did a few tests:
1 Hand at āroomā temperature.
While I was moving the camera around to take this image I was able to convince myself that at certain angles I could make out a vaguely cooler blob but I think it was just a combination of wishful thinking and knowing where the chip is.
2 Cooled the area around the chip with ice
The chip (a 2x12mm NTAG216) is pretty much in the centre of the darkest blue area
3 Warmed the surface with water.
I used warm water because it conducts heat so efficiently that I thought that gave me the best chance of rapidly heating just the surface.
Objectively, despite occasionally deciding that maybe I could see a very slight difference, I think this shows that heat cameras donāt reveal chips. Partly because, as Erequiet said, the reading is superficial so the chip would have to cool down the skin above it to show up and partly because I think that chips are so small and so completely enveloped in the skin around them that they probably cool/heat at almost exactly the same speed as their surroundings.

Iām glad someone tried 
Did you keep looking as the cold one warmed back up? Also maybe something like an xG3 would be more noticeable?
Also big flexes. They create a barrier between the skin and the rest of the body 
Do you know if a 20 buck IR flashlight type will work?
Or does it have to be a professional job for a couple of grand?
I watched the whole thing because the viewfinder of the camera shows you in real time.
Something with a bigger mass to warm up may work better but I think that a barrier with the skin is actually counter-productive because to show up the object has to cool down the skin above it.
A bit like the fact that the light from a blinky is mostly the light that is diffused by the skin above it.

You can use visible light if youāre patient and have done some photography before. Itās cheap depending on what you already have

Id love to hear it
I dropped the idea of teh V1 as sensing isnt gonna happen in that location, but a second V2 would be extremely useful ā¦
Ive done some testing with a small neodymium magnet āabout the size of the G3ā and 1in seam a hair too close ā¦ but there is absolutely no attraction at 1.25" to 1.5" ā¦
Yeah,
When you first join, i think you have 5 days to change it.
After that, An admin can change it.
Itās preferred that people dont, and we dont want to be constantly changing peoples usernames on a whim when they get bored of it.
Try keeping up with Discord where people are constantly changing them.
You have easily earnt a name change if you want it, and if you choose to, at least it will be public and people will know from these posts.
Ideally, if it is something similar, that would be great, but not necessary

Are you wanting to put them side by side or end on end?
Well my common username is just Az. I just made up the flyer part at the time for websites that didnāt accept 2 characters or when it was taken. I donāt know if either is the case but if not Iād love to be Az or Az F.
