Hi, I'm a newbie and want to make some led drip tube lights. I don't know where to start or what products to buy. Thanks for any input
They will look like these

Re: led drip tubes
Those are NOT a newbie project, that would be a fairly advanced and costly project.
And honestly with the cost of what's needed to pull that off, I can promise you it would be MUCH cheaper to just buy them.

That's my thoughts... :)
But if I were to make these I would use neopixel strips or something similar and then use a bare ATTiny 85 IN each tube to control each strip individually and then just feed each tube with a 5 v supply string they can also hang from, The dripping would be statically programmed so they would just do one program and have no communication with any other tube. They would just drip

Hey. Thanks for your input. Guess things that look simple are not always huh? I've seen these things for sale all over thailand. But they are not all that cheap. I might still try to make one just for fun:)

If you don't want to work with a bare ATTiny 85, we do have the Trinket boards based on the same processor:

Re: led drip tubes
Using Fastled that isn't too hard to make. Although I agree is isn't an easy first project :D Even this code as rough as it is needs more work, a delay to slow down the 'drips' for one!
Video of the code: https://www.youtube.com/watch?v=3gRNGH-EUdE
Code: Select all
#include "FastLED.h"
#define DATA_PIN 8
#define CLK_PIN 9
#define LED_TYPE LPD8806
#define COLOR_ORDER GRB
#define NUM_LEDS 32
CRGB leds[NUM_LEDS];
#define BRIGHTNESS 255
#define FRAMES_PER_SECOND 120
byte led_pos = 0;
void setup() {
delay(3000); // 3 second delay for recovery
// tell FastLED about the LED strip configuration
FastLED.addLeds<LED_TYPE,DATA_PIN,CLK_PIN,COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip);
// set master brightness control
FastLED.setBrightness(BRIGHTNESS);
}
void loop() {
// send the 'leds' array out to the actual LED strip
FastLED.show();
// insert a delay to keep the framerate modest
FastLED.delay(1000/FRAMES_PER_SECOND);
fadeToBlackBy( leds, NUM_LEDS, 100);
leds[led_pos] = CHSV(0,255,255);
led_pos++;
if (led_pos >= NUM_LEDS) led_pos = 0;
}
