pool light

[capwizard]

My pool light went out (Pentair 77163102 AquaLight Halogen Quartz Light with Stainless Steel Face Ring and 30-Feet Cord, 120-Volt, 250-Watt) because wires inside the connector to lamp base are burned and i don't want to pay $200 for a new lamp base with wire cable and $20 for quartz lamp (picture 1,2) so i modified $20, made in China, DC12v 10W, 900LM, IP67 Waterproof, with Remote Control , RGB led light onto it.


but it leaked water so i have to open it.....

Re: pool light

then i siliconed it but i need to dive-in to use remote. i should move the IR sensor to outside.

Re: pool light

this article help me Identify the part number of U1.
---------------------------------------------
I got a similar device and spent a while playing with it.

Mine uses a fixed PWM period of 6400 µs (156.25 Hz), divided into 80 x 80 µs ticks (12.5 kHz PWM clock). The LEDs are wired common anode so the low side can be switched.

The 8 dim levels are 12.5, 25, 37.5, … 100% on, 10, 20, … 80 out
of 80 ticks of on time.

The “DIY” buttons support 28 dimming levels, which are 0, 3, 6, …, 75, 78 or 80 ticks of on time.

The fades use single-tick increments.

Internally, there’s an 8-pin PIC12F5xx microcontroller (with the P/N sanded off, but the power pin locations give it away) connected to an Atmel 24C02N I2C EEPROM.

The pin assignments are:

1- Vcc (generated by a series diode, 680Ω R, and 4.7V zener)
2- SCL (10K pull-up)
3- SDA (5.1K pull-up)
4- IR input (another giveaway this is a Microchip part)
5- Blue output (470Ω to the gate of the low-side transistor)
6- Red output
7- Green output
8- GND

There’s a 0.1 uF capacitor in parallel with the zener diode.

The IR receiver is powered through a 100-ohm resistor followed by a second 0.1 uF decoupling cap.

I haven’t tried dumping the PIC program ROM.

Re: pool light

I try to add more lights around the pool to create the atmosphere in these videos

Re: pool light

Nice! I should do the same...

Just need a pool first.. And a house.. ☺️
