Water and electricity don't mix?

I just have it mocked up right now. The LEDs are taped to the bottom of the counter and the wires are.... we'll just say... uninsulated. I ordered some bezels for the LEDs, and I've got some JST connectors to wire the lights up in a more permanent way.

I'm thinking about making the switch work like a touch lamp. Has anybody worked with that kind of circuitry before? Anybody sell a kit, or will I have to go hunting at goodwill?

So are you using the water as the conductor? Is this low voltage or 110v AC? More details plz
Looks cool

I found this touch lamp module:

Can't beat the price.
However....    This is for the 120V ac side of things.  Perhaps you can have it turn on the transformer that powers the low voltage DC for the LEDs.  Needs some study.
But you can't beat the price.

P.S.  If you place an order, please add 2 for me.  I'll split the shipping with you.

Larry, thanks for the product tip! I'll definitely order extras if I get any. Phil could probably find a use for them as well.

These are running on a 24VDC wall wort that I had laying around. It's not permanent, but it worked for the mock up. They're two parallel circuits with 4 LEDs each in series with some drop resistors (I forget the values at the moment). I think in the final version, I'll use a lower voltage supply (one that's smaller too).


The AC adapter under a sink had me worried a little bit, but the bulbs are mounted through a wooden counter beneath the vessel sink. Nothing actually touches the sink, drain, or supply lines, so as long as it's a low voltage circuit on a GFCI I'm not terribly worried about it.

looks awesome.
nice work Jim.

I have seen a shower head that turns water colors with LED, I think it was linked to the water temperature. It probably was on some HGTV home show or maybe "I want that" show?


WOW, just googled "LED water faucet" ...neat stuff.

hmmm, wife has been bugging me for months (maybe a year or two really) to replace the kitchen faucet.... lets see, how can I justify some leds for the project???

Amazon sellers are pretty tricky... I found some that were cheaper, but there was only one available at that price and it wasn't eligible for free shipping. The one that Larry found charges you $4.99 shipping PER UNIT!


I ended up getting 5 of these instead.

They seem a little more hackable, we'll definitely have to reverse engineer one of them.
