Ahh - have you seen the Sparkfun wall version - video at the bottom.They have a keyboard hooked up to type as you go, but liked the end where the Ardunio checks twitter for a hashtag and spells it out... pretty cool stuff! I need to get this sorted and merge in some of the Sparkfun ideas too :)

Yeah - Blynk would work. You could also have a WiFi interface using an ESP8266 and a basic web form to save a text field.I was thinking more manually though - you press the rotary encoder to access "a menu" to start recording. You then turn it clockwise/counter-clockwise and the bulbs light up one at a time till you get to a letter. Press the encoder to store... move to the next letter... etc etc... and then save somehow. like a long press. The Arduino would then loop through the custom string text... P...A...N...T..S... L...O....L.... or something?!!! :)
Ahh great idea, loved that series too!Like all the extra ideas from people too - motion detection, ESP WiFi controlled, flickering etc. That's what I like about reading the comments - you get more ideas to take the project to the next level. I would also maybe add in an LDR to control the neopixel brightness compared to the ambient lighting. Maybe swap the button for a rotary encoder and you could add in a "writing" mode where a user could loop through the bulbs to enter a custom string and save it to the program to go through?!Cool stuff!Steve

Simple 10w Bluetooth Portable Speaker
What a brilliantly simple project, well written up and well designed! This has wet my appetite for producing my own custom circuit boards - yours looks great and AutoDesk Circuits looks simple enough to get started! Need to get some Tiny85's too, another excuse to get some!Thanks for the Instructable and the inspiration to investigate simple circuit design!Steve
