This is not as much an instructable as a record of how I made a school project. While repeating exactly what I did will probably not help you, this project can be modified to make almost any display more eye-catching.

Step 1: Come Up With an Idea

I know this sounds stupid but it is necessary to know at least roughly what you are trying to do. In this case, I wanted to somehow incorporate astronomy and draw attention to my poster. With this in mind, I came up with a cheesy saying and a plan for the placement and animation of the LEDs.
I saw what is a microcontroler at radio shack and was gonna buy it, is it good? i can make a small robot as soon as i can program micro controllers
I would recommend an Arduino, they are about $30 and are pretty powerful. They use C, but come with many functions that make I/O SOOO much easier. Also, tons of people use them so you can find answers to your questions easily
It is a great microcontroller to start out with, I would highly recommend it. In addition to having a built in battery clip, programmer, and prototyping board, it comes with a 300+ page programming guide and an assortment of components. The only problem that I have found with it is that it uses PBASIC, so if you want to use anything other than a Basic Stamp later you need to learn a new programming language.
Thanks! Now to pay off various debts and to get one hundred dollars DX!
Have you thought of using SMT LED. They can be mounted flush in the cover. Plus a larger amount for a better look
Thanks, that's a good idea. At the time I made the poster I didn't even know the difference between SMT and thru-hole components, let alone how to make my own circuit boards. Perhaps I will track down a copy of Eagle and make a version 2.0 next time I have to make a poster for school.
Nice instructable! Well done! The only thing I may have done differently was maybe have used less delay between the yellow LED's so that the loop was faster. P.S.: I have the same Crescent flush cutters sitting in front of me this very moment!
Haha yeah. That was so funny that the cops there got their panties in a bunch when there were some flat circuit boards with LEDs in them. For those of you who don't know, it was a low budget advertising campaign across 10 cities for the Aqua Teen Hunger Force movie. Boston is the only city that freaked.
no they all freaked i know for a fact that philly had patrol cars searching for them when word broke
At your age, i was still trying to figure out why 2 leds don't take double the voltage 1 does. Good job, I wish I figured stuff out earlier. BTW, I feel bad that you had to buy all that stuff at radio shack, they quadruple the prices from what they pay for them. If you don't mind waiting, even buying parts online and paying for overnight shipping can be cheaper.
Well done, good job. Blink, Blink, BOOM
oops Blink, Blink, Blink Boom
Nice job, thanks for sharing, it's pretty cool!
Boy do I know the feeling of "I happen to have this clunky programmable thing, but it'll do." Good job!
Great job kid thanks for sharing
