You may remember Mr. Michaud delivering a post about the incredible LED sign at the begining of this last month. Since then, there have been a few updates from our Canadian friends at hacklab.to.

First off, they have provided a live stream of the sign for the entire Internet to enjoy.

From all the times I have checked it out, it has been a clock. Too bad Flava Flav is a bit too scrawny to hold that sucker up. If he could, I still doubt he or most people could also carry around enough mobile electricity to make it worthwhile. Maybe if we are lucky, the hacklab kids will see this and make it a reality. Yes hacklab, I’m challenging you.

Second, Andrew Kilpatrick has provided a wonderful technical writeup of the “getting it to work” process. This project is fairly impressive, not because they built out a sign that uses 3,072 LEDs, but because they also had to do a bit of reverse engineering to do so. The sign was built from a number of surplus LED sign panels. This was a good idea as designing and assembling something that size would be fairly expensive, error prone and incredibly time consuming. No matter how much you love playing with electronics, be it for work or hobby, soldering 3,000+ LEDs WILL get tedious and boring. Why re-invent the wheel when you can benefit from someone else’s hard work? Especially when that someone may have been a small team of engineers that over-designed and mass produced something that fits your needs. Even if you have no technical documentation and only your wits and some basic electronics gear to figure it all out, its worth it in the end as you’ve learned something.

After poking at the boards over a weekend they found it required only four control pins and had some pretty neat control options. They ended up using the hacker’s defacto microcontroller (Arduino) and some clever code to light up the daisy chained panels. You read that right, they were designed from the start to be plugged into each other.

I would go into more detail, but like I said earlier, Andrew has done a wonderful writeup of all the details you could want. He and his crew definitely deserve the spotlight. So go check out the writeup already!

Syn2cat Arduino Party

Eric Michaud | Posted 2009.03.02 at 8:19 pm | Perma

Our friends in Luxembourg from syn2cat are having a little get together that is open to the public (as long as you RSVP for the 10 spots), to put together a number of Arduino units for your hacking pleasure.

arduino316

From syn2cat’s wiki post:

What is it about?

On the 15th of March we are going to solder an Serial Arduino Board and a few Velleman Kits to afterwards.
Hack them and make them behave in a different way than originally conceived. (Limited to 10 People! Deadline: 8th of March)

We will provide

There will be approximately 6 full soldering stations
with all the necessary gear (Multimeter, Wirecutter tools, etc…)

These sets will be available FOR SALE. So in case you like what you did
and want to become a REAL Pirate make a future proof investment.

Most of the Kits will be in 3 exemplars, if you are really keen on one, reserve it please.

  • A Room (kindly provided by emQue)
  • 6 30W Soldering Irons with an adequate Tip and stand (but please bring your own should you have one)
  • 6 Third-hands
  • 6 Multimeter (again, you have one bring it please)
  • 6 Ubuntu Laptops with the Arduino IDE
  • Power supplies (some regulated some not, Voltage varies)
  • 500g (yeah) of 1mm and 0.7mm Solder
  • De-soldering stuff
  • Maybe an Oscilloscope (Who can bring one please?)

More details can be found on their wiki.

This event is also a wonderful way to meet the members of syn2cat and possibly even become a member yourself!

Cheers,
/E.
