Rainbow Jellyfish

Convenient indicator LEDs for your breadboard

Similar projects worth following

>I sell on Tindie

After making #Nyan Board I wanted to explore the rainbow wires theme a bit more, but this time with something original, that I could actually get out to people without having to worry about copyright infringement. I also wanted to make it a little bit more useful.

After playing a bit drawing various dumb unicorns, I remembered that I actually like tentacles, and that there are many see creatures that are colorful and shiny. So I decided on a jellyfish.

The idea for the device is very simple: you just have a bunch of LEDs with matching resistors, colored the same as the wires coming out the bottom, except for the ground wire, which is common for all LEDs (that's fortunate, since there are no brown or black LEDs). What is is good for? You basically connect it to your breadboarded projects to see the signals on the pins. You want to test the blink program on a new microcontroller? Easy!

    The initial prototype PCB worked great for singles, but now I want to start selling kits, so I need to panelize them. Initially I just slapped a few of the boarrds together and added a few tabs to connect them, but when I submitted that to be fabricated, it got rejected. So today I sat down and panelized them properly:

    I could probably pack them denser, and get less problems with the "mouse bites" somehow, but I think this is good enough for now. This will give me 160 PCBs in total. I varied the silkscreen on them slightly, to give them different facial expressions. Ordered them on white PCB with black silkscreen. Should arrive in a few weeks — in the mean time I need to figure out how to package the components, in particular, how to mark the colors of the LEDs.

    This was a pretty quick project, but it's also really simple. I have the three PCBs I got from OSHPark assembled and on sale at Tindie. I also ordered proper PCBs now (white), and I will sell them on Tindie as kits when they arrive.

    The PCB design is now published at OSHPark, so you can also make your own.

I would definitely buy one or two on tindie as a kit :P

That's a pretty useful thing actually :) and cute!

you could also make a tiny spider where the eyes are leds and the cables are legs

Somehow I don't associate spiders with colors, even though there are some very colorful ones, like the peacock spider.
