Raspberry Pi RGB LED Strip Controller

Hi there,

I've made a few RGB LED strip driver boards for my project (see pictures below).

Due to minimum quantity requirements I had to order more boards/parts than I needed, so I ended up with some extras. I would like to try to sell them to recoup some of the costs. I currently have 5 of them ready-made and have enough parts to make 5 more.

The boards can be stacked on top of each other and each channel (R, G and B) has a 4-position jumper to select from 4 different pin combinations. So, one can stack 4 boards and control 12 channels (or 3 sets of RGB LED strips) from the same RPi.

The boards are made for RPi Zero (W), but they will also fit onto regular RPi (I've tried with model 3B+ that I have).

My questions are:

1. Would anybody be interested in getting some of these?
2. What do you think would be a reasonable price? I was thinking $25 + shipping per board.

25 seems a little stiff but we can talk. What country are you in?

I'm located in the US. Florida, Tampa Bay area.

Not stuck on $25 - I just threw it out there. Whatever price you are comfortable with, I will probably be able to do it. :)

Hey man, I am either blind (which is possible) or the forum doesn't reveal other users' email addresses. Anyway, I snuck in my email under my YIM contact info :geek: Drop me an email and we can go from there. Thank you.

In case anyone is interested, I've got 4 more of these boards made.
This will be it for a while, as I will need to order more parts/boards after that.

Totally worth it. I love the ones that I bought and am having a blast with them.

Many thanks!

Thanks for the kind word @drushtx :D

I just finished writing tutorial on how to turn Raspberry Pi into a Wireless Access Point:

Took me a while. :o

Next, I am planning to make a tutorial on how to create a web page with 3 sliders to control the boards over wifi.
