	I found an "Ocean Wave" lamp in a drawer this weekend. It's something I got from AliExpress at one point because I thought it would be neat for themed lighting in my living room. But I never got around to actually using it. It's not that it's bad (ok, maybe a bit), but it is just a hassle to use it.		I found an "Ocean Wave" lamp in a drawer this weekend.

	The lamp consists of two parts bolted together with a mechanism that makes it possible to adjust the projection angle. The base contains the electronics and buttons, the top part has a transparent top with some jiggly texture that acts as a lens. Within the top is another smaller jiggly lens with a panel with 12 LEDs, 4 for each color channel, underneath.

 Sure thing, I could just open it up and slap an ESP32 on it. That way I can hook it into my Home Assistant setup and have it automatically switch on whenever I select a specific lighting scene.

			The R, G and B LEDs all have their own wire running to the board which is neatly labeled. Not too far from the board contacts are a bunch of FETs to drive them. The same goes for the motor, which has 2 wires. Through some volt- and continuity measuring I figured out where these circuits could be powered.
