Color Changing Glowing Faucet

This is a follow-up video from the previous demonstration.

Rectified issues:
1). Temperature sensor was shorting out due to shoddy construction. Had to cut out the probe from the glued mass, re-solder, and reposition the probe within the standard fitting.

2). LEDs would not turn off when water was shut off because they were positioned in an area where water was trapped once flow had ceased, thus maintaining continuity between the wire leads. After positioning the wire leads in the very outlet of the fitting, this (mostly) fixes that problem. The stray water drop will sometimes make continuity though.

The LEDs, current limiting resistors, temperature probe, and water continuity sensor are all crammed into the that standard faucet fitting, the LEDs and resistors are encapsulated in thick glue. Actually, everything is encapsulated in glue except for the water continuity sensor.

This is a proof-of-concept design (extreme lack of aesthetics). The water stream itself does not have a great shape, especially when the water is running fast. I can not do much about it without re-designing the whole arrangement.

Let me know if you want the code (in C). I might not be able to get it to you soon.

Were you planning on writing an Instructable of this project?

@Firebread00

I didn't document it, so I probably won't.

This was weirdly entertaining...

Theyre sold everywhere in stores

I would like to say this would be great for a person that has trouble feeling HOT/COLD or even some elderly people whom over the years have lost some of their feeling. How much do you think a unit cost? Would their be a way of making the circut smaller and adding a little paddle wheel to a micro motor, this could generate the power required for the circut, and the use of resin could waterproof it all. Yes, you may need to make the enclosure a little longer. Could have many uses. Well Done!!

I see. Well it is a cool project all the same, but you should definitely cover up those loose wires.

id love the code too.

LOL you truly live in a hackaday house

[loftylad1]

I love it :)

I'm gonna make one !

Could you send me the code please?

I'll be writing mine for PIC16F chips but it would be nice to see how you did it.

Men! This is amazing!
