XBees + Arduino

Although it’s been a while since I last worked on this project, things are continuing to move along. I finally assembled the Ladyada XBee adapters and successfully passed a message between the two XBees.

So, I’m not the best solderer and the first adapter I worked on suffered from an overusing tip on my soldering iron, which made heating up the solder with the tip of the iron next to impossible. There were also some issues (that remain unresolved) in terms of configuring the XBees, but thankfully that step seems to be unnecessary (at this point anyways).

Getting Things to Talk: Arduino + LCDs

I spent the better part of the day on Saturday doing some more basic research into connecting an Arduino and LCD for this ongoing project. For the most part, it’s pretty basic and following the wiring diagrams and tutorials online is fine.

I ran into a problem with getting text on two lines, which I’ll detail below. Next on the to do list is to order a different LCD, maybe a 4×20 display and maybe something even smaller and then do some work on the text processing part of this whole thing.

Overall, it was a good start and I’m anxious for later this week when I’ll have a block of time to continue with the next steps in this early research.

The LED Sign is Finished!!!

MAKE THINGS HAPPEN, the LED sign is finished!

It’s taken a number of weeks, but we finished wiring the LED sign at tonight’s Office Hours! It was a pretty incredible moment to plug in the sign, turn off the lights, and realize that we made this come together. I’m really, really, really happy with how it turned out!!! There are still a few more things we need to do before this project is completely done, and I would like to try it on batteries, but now that we know how bright it is, I think we’ll come up with some more LED projects soon.

LED Graveyard

dead LEDs

I went through our LED sign today and removed all the LEDs that had died in our earlier efforts to learn electricity. So now we’re ready to replace these and finish up the sign! 12 out of nearly 200 LEDs isn’t too bad.

Moving Along with Flagging Tape and LEDs

Broken City Lab Office Hours, moving forward on lots of projects

Broken City Lab Office Hours on Tuesday were hugely productive. We completely finished getting all the resistors on the LED sign, measured out all the letters with flagging tape for the EC Row Project, organized some logistics for the planning stages of a couple other upcoming projects, and figured out the title for our upcoming show in the Lebel Gallery.

Lots of photos after the jump.

Continuing Work on the LED Sign

Continuing work on the LED Sign, Make Things Happen

Michelle and I finished soldering the anodes on the LED sign yesterday morning. Next is soldering all the resistors to the cathodes—this is a hilariously longer process than I think any of us anticipated, but it’s good. I’m really looking forward to seeing it lit up!

Also, thank you to whoever passed on the big roll of 4″ red tape!!!
