My new favorite toy

This is what I just finished building.

Can you guess what it is and what it is used for?

 

Looks like a Sex Toy gone wrong.....lmao

 

/me <facepalms>


edit:
(I did laugh however because I halfway expected that at some point in this thread)

 

Wild guess: a laser pen for transmitting audio?

 

At first glance it appears to be a flashlight, but I suspect it is more complicated than that.

 

*votes for taser, even if it doesn't look remotely possible with that setup...not that I know anything about them*

 

a pen that uses wax of some sort ? !

 

You are right on track, but it sends a signal which is collected on another diode and processed by my pc sound card in order to complete it's mission.

Now a laser is another one of my projects actually a cnc laser cutter to be precise but we'll get into that some other time

It is a "flashlight (penlight actually seeing as that clear tube is actually a disassembled kaleidoscope pen I had in a box-o-crap from years ago.)" of sorts with a specific purpose having nothing to do with illumination, and you are correct this is only one third of it, though if I posted the other factors it would give it away.

HA! have built one of those, safer and for the leisurely hackster cheaper to buy one

 

Sonic screwdriver?

 

LMAO
Think non visible light from the electromagnetic spectrum

edit: clue
wavelength 980nm

A Ir signal blur

 

That is exactly what this produces, a blurry diffuse disc of infrared emittance ...
Now for the hard part, what am I using this for?

 

drive your wife mad

 

Lucky for the non-existent wife of mine that she doesn't exist

I'm sure if she did though I would have already driven her bat-chit crazy

 

Thermal image synthesis ?

 

A pen that guides you on how to draw better?

 

To plan on a map, your missions to Apple orchards?
