What is this!!!??? Answered
Someone gave me a small electric project and one of the part is now broken:(
Its part of a heart beat monitor...
there was 2 tubes like like plug into the machine.
How the machine worked ; When you were touching the 2 tubes with your hands, its automatically started to pulse light (in the 2 tubes) It then synchronise with your heart beat.
Now, I cant figue out How a kind of neon like this could DETECT AND GLOW at the same time?!?!?!
The two output connector ARE SHORTED TOGETHER!
And the big question is: WHAT IS THIS part!! i would like to replace it.
It doesnt look like a neon, not even a lamp! so...???
I think its a kind of laser diode inside.
You dont see very well on the picture, but inside the white ring on the top of what i think maybe is a laser diode, is empty, theres a hole
the rest of the white glass tube is empty.
Its the top part of the tube (dont see in the picture) is broken.
