@Caleb: The 32. She made them right before the more densely populated strips and I made a joke about it being bad timing. She pointed out that the tighter strip wouldn't have handled the bend she needed as well, so it was a non-issue.

It looks like they have a new version using the 60-LED strips -- check out this page:

@Caleb: I've seen Becky's LED shoes and they're pretty damn neat.

I saw those shoes on the Adafrity website -- they look SOOOOO Tasty -- did she use the 32 LEDs/meter or 60 LEDs/meter strips?

yeah, they recently added some that are incredibly dense but not quite as flexible. I've seen Becky's LED shoes and they're pretty damn neat.

oh nice! I love when I find that out in the wild. you can lean back and forth and it will appear to bend in front of you.

I designed a lighting effect for a boutique once that used a variation of the "infininty Mirror" idea.  The boutique occupied a very narrow spot in a strip mall. I put several round mirrors on the walls carefully aligned with matching mirrors on the opposing wall.  Each mirror had a ring of LEDs around it. You could stand between the two mirrors and see yourself in a "tunnel" to infinity. We later added a slight angle to one mirror of each pair to make the tunnel curve. Skewing the pattern fed to the two rings of LED's by one or two LEDs caused a nice spiral effect.

Hi Max: I think these led strips on a reel are amazing.

Whilst not as flamboyant as your use, I am using white led strips for solar powered house lighting. My excess day time solar electric harvest is conserved in 12 volt lead acid batteries and allowed to light the rooms at Crusty Mansion during the night. To reduce a duplication of switch wires for the low volatage system I am using these very neat inline radio controlled switches, (could not make them for the price)

With regard to the NeoPixel strips, there are pictures on the Adafruit website of them attached to sneakers -- these would have looked amazing on the dancefloor at university discos when I was a student.

What am I saying? They would look amazing on my feet as I sit here in my office ... I think I can feel another urge coming on!!!

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
