A simple badge, for a simple purpose.

We'd discussed making a badge for our group during and after DC 25, and had a very rough prototype but when I suffered a knee injury the original project kinda died. Fast forward to this spring, I wanted to do something different for my blinky tiara, and thought something PCB based would be fun. While working on that project I realized that the basic circuit design also would lend itself to a badge, drew one up in easyEDA and ordered prototypes.
All the badges made it to Vegas. Yay! Got to spend some time with Mrrobotbadge. Spent quality time teaching basic soldering. The utter joy expressed by a N00b who soldered up a few LEDS and got them to light up is tiring but so much fun.
On a side note, I hear that Bryan might have to get a tattoo.
Note to self, do presales on tindie next year.
Before I forgot I added the gerber files - minus the LHC artwork. Edit as needed for your own blinkin projects or learn to solder board.
I spent the month of July soldering, So much solder, nights weekends I even took two vacation days just to make sure I had them all done in time. I also learned that if you order a replacement part from Digikey or 1000 of them, within 48 hours of getting your Digikey order, you will get the part that was holding you up from China. Also how many CR2032's can yo order before they put you on a watch list? Asking for a friend.
So I ran a continuous use test, it took 96 hours to kill the two 2032 coin batteries of questionable origin.
So since I really didn't have a lot of time, mid may is not the time to start designing a badge. I followed the Keep It Simple Stupid rule, I found a basic project from an electronics class I took and adapted it to my needs. Start with the venerable 555 timer, set that bad boy up in astable mode to generate a square wave, send wave to a decade counter and hook an LED to each output pin. Simple.
Arrange components in an artful manner and wait for prototypes. Also simple.
Thanks, I really can't take credit for the graphic though - it was the same one that was used on our group's T Shirts.
I was commenting on the quality of the silk screen. Sometimes these will come back from the fab and the resolution will be poor, edges will not be smooth, or the large solid areas may have variations in color. This one came out really pretty!

I like it! I'm coming in close to the line with a small-run badge myself. I just started laying out the circuit yesterday so you're incredibly far ahead of me ;-)
Nice work on the silk screen graphics for this one!
