Another Dollar Store Upgrade

scottiebabe
scottiebabe over 2 years ago

A set of street lights with no lights!?

image

As far as I can tell they were designed to include a light source, as the pole is hollow and the base cap has a slot for a wire...

image

For those of us that know how to solder, there is an easy fix... An LED!

I decided to splurge and use an addressable programable LED (a ws2812b)

image

I soldered a wire to each of the 4 pins and added a dab of hot glue.

Before

After

Huge improvement!

Those in the know, might have noticed I didn't add a decoupling capacitor to the ws2812 neopixel.

I'll try to post a scopeshot of the output dataline to see what kind of trouble the IC might get into (or not) with the omission of the decoupling cap...

    I've always wondered if a Dollar Store item's price in Canada is 1 CAN$  and the same item in the US is $1 USD. mmmmmm

    I have to stay out of the Dollar Store. They sell Red Hots candy and I'm a Red Hots addict. Darn things cost $1.25 tho. 

    Nice job Christmas decorating Scottiebabe.

    I have omitted the decoupling cap lots of times on WS2812 and have never had problems, usually but not always powered with batteries. At least not yet. I’m interested to see what the scope shows.

    Neat job. 200% better.

    The tree looks like it has wires too - does it light up or is it just the strain relief?

    It looks great!

    At first, I thought you were just using the DD for scale.

    But you're programming the ws2812 through it, aren't you?!
