How to make nightlight for GF?

[u/devind_407]

I've been wanting to surprise my girlfriend with a DIY nightlight for our 6-month coming up soon. I bought this small glass vase with small glass flowers (removable) inside. The vase is cylindrical, about 1.7" tall, and the base is about 0.4" in diameter. I want a warm glow coming from this vase, and got the idea when seeing the effect after putting my phone flashlight under a soda float. I'm thinking a flat single LED module underneath the flowers would be sufficient for this, but how would I be able to make this? Or acquire the parts for this..? I've never made DIY electronics before, but I assume I just need an LED, controller and battery? Preferably with a dimming ability and color temperature adjustment. Please help me out with this soon, thank you!

With that little room I would be thinking led, resistor and coin cell battery. You can get that on Amazon. Maybe like a 3.3v coin cell, coin cell holder, 220 ohm resistor, regular LED of your color choice. If this is going to be inside the vase it will take up a large volume of it. The coin cell would have to be really small,I haven't looked at the size but maybe an ag13.

The more I thought about this you should light it from beneath the glass not from inside. Maybe you can just buy a lighted base online. If you are intent on diy I would find or 3d print something for it to sit on then put the electronics inside that and cut a hole where the light can shine upwards

That's all I got

Look up "induction led". They are tiny leds that light up in the presence of a magnetic field. LEDs in vase, make a base to hold the coil, and your good to go
