A fun, scary night along with mild temperatures in the mid-50's with a light drizzle which added to the great effect lighting and numerous fog machines. We had over 400 plus trick-or-treaters checking out the Halloween themed haunted graveyard my wife and I set-up every year. Filled with numerous smoke machines, high-intensity white and amber strobe lighting, red super LED lighting, compressed air popper, torches, a radio controlled skull, and music.
Interesting fact: Unlike incandescent bulbs, LED Christmas lights do not burn constantly. They flicker on/off many times per second. This photo illustrates that.
I forgot to unset the 2-second delay and pitched the camera forward to see what was wrong. While looking at the LCD screen, the camera took this 1/4 second shot.
While the CFLs and daylight in the picture are fluid, the LEDs on my deck are staccato.
Lightline 1250
Product Description
Lightline 1250 is a high performance LED desk lamp designed for offices and home studios. LEDs provide a color rendering index of over 90 CRI, whereas 100 is natural sunlight. When combined with ultra bright LEDs producing 1100 lux of brightness, the Lightline 1250 LED desk produce bright, clean light that can enhance worker productivity.
The brightness can be adjusted by a capacitive touch sensor in the base of the lamp. As an added feature, the base has an integrated USB slot enabling the charging of mobile devices. The Lightline 1250 LED Desk Lamp is available in midnight black and arctic white.
Key Features
Lumiy’s LEDs are among the best and brightest in the world. The LEDs produce an astounding 1100 lux of brightness.
LED enable a color rendering index of over 90 CRI produce sharp, crisp lighting. Lumiy produces near to perfect natural light, whereas sunlight is 100 CRI.
Capacitive touch sensors are seamlessly integrated into the base. Touch sensors adjust brightness, 1100 lux - 300 lux.
Experience huge power, and cost savings through high efficiency, ultra bright LEDs. LEDs use only 1 watt of power on low brightness and 7 watts at maximum brightness.
Lumiy’s sleek, compact design with its ultra bright lighting is perfect for today’s high functionality modern offices. The slim captive touch sensor base saves desk space.

Also shows the results of my first real attempt at SMD skillet reflow. (woot!)
(wish I could get the lighting/exposure to both be long enough to hide the scanning but short enough so the light from the LEDs doesn't blow out the image)
Super praktische Leder Schutzhülle für das MacBook! Praktisch, da das MacBook gut geschützt ist.
Haptisch ist der Einband ein Erlebnis: kuschelknautschiges Fettleder gefüttert mit dickem, reinem Wollfilz!
Zwei Lederbänder werden einmal um die Tasche gewickelt und an der Rückseite untergeschoben. Somit wird die Tasche sauber und sicher verschlossen.
Haciendo limpieza en la caja de componentes electrónicos, voy comprobando los led que no "lucen" con el polímetro y también para ver si son infrarrojos (IR).

Here's the circuit for the Black Box Lightshow. I'm pretty sure it's right. And now, an explanation:
The LED array is shown here as individual diodes, though I used six 5x7 LED arrays, each one is 2" tall. They are arranged as 14 rows and 15 columns. The left channel is 8 columns and the right channel is 7 columns. The extra column from the left channel is the center column and gives nice symmetry. Not shown here is that on the right channel, the first column (pin 1) is not used so that the other columns are equal.
The LM3914 is a Dot/Bar Display Driver. It does all the heavy lifting of converting the audio signal into a series of bars - these are typically used as digital meters. The potentiometer sets the sensitivity of the display. Since the rows are multiplexed (see below), each column is only driving one LED at a time. I only show the left channel here, the right channel is identical, and they share the level setting potentiometer.
The right portion of the diagram is a 555 clock, a 7493 4-bit counter and a 74154 4-to-16 line decoder/demultiplexer. This is the "sweep" part of the display that cycles through each row of LEDs. The potentiometer at the top controls the sweep speed. The net result is that the 74154 is cycling through the pins/rows, grounding each in succession. Note that I only have 14 rows, but it is counting to 16 each time. No big deal, it doesn't affect the perceived output at all.
The N2907 transistors are there to provide enough power for all the LEDs. Potentially, all 15 LEDs in a row can be lit up at once, so the transistors make sure there is enough juice.
Unfortunately, I lost the original plans during a garage cleaning after I built the electronics (the box took another few months before I got around to it). I opened it up and reverse engineered my own work. I won't guarantee it, but it sure looks right to me. The one weird thing I found is that I don't have power going to pin 8 of the 555 (as shown here), but it works fine - go figure. Also, I'm not 100% sure I got the polarity of the LEDs right, sorry about that. I would recommend testing that out first.
Please post if you build this and let me know! Also, happy to answer questions along the way.

It is hardly seen on this photo though, but instead of normal light tubes, this bus is equipped with a row of LED's hidden in the tub that act as normal tubes. This seems to be done to make the lightinig energy effictent.

These headlights have true carbon fiber wrapped bezels, trimmed to fit Vettesthetics.com "Hammerhead" LED units, which have been upgraded with Nichia 50ma superflux LEDs for the brightest possible output. The chrome projector rings, as well as the chrome reflector bowl behind the clear side marker lens have been painted in 2 stage Gloss Black to match the painted Hammerhead units.
A Bat had decided to make camp on our LED video screen in Willow's main auditorium. It took turning the LED screen to full brightness and quick flashing color patterns to wake him up and then he decided to fly off the screen and disappear into the darkness of the stage...he's still around!!
