WARNING: DIY GRAPHIC VIDEO

//

A son of one of LVL1′s members got a little too close to a bandsaw over the Christmas break… Remember, safety first! But what started as a lesson on what *not* to do (i.e. don’t be too cavalier with a bandsaw) turned into a nice lesson on DIY stitches. Why would you stitch yourself up? His explanation was “something something waiting rooms something something scar tissue.”

Remember if you can’t fix your body, you don’t own your body.

Teletron Composition @ Louisville Soundbuilders

//

Video of the Teletron Demonstration. This was performed at the 1st meeting of Louisville Soundbuilders at LVL1.

Score by Robert Schneider (The Apples in stereo). Performed by Robert Beatty (Hair Police) and Robert Schneider, September 20, 2010, at LVL1 Hackerspace (Louisville, Kentucky), using two Moog MG-1 synthesizers with two Teletron mind-control interfaces. Conducted by LVL1 president Chris Cprek (Pax Titania, Nzambi).

Fun with the LOLShield

//

We had a fantastic weekend at LVL1. Not only was LVL1 at an awesome Actors Theater event, we also had some important visitors at the space on Saturday! On Saturday, Mitch Altman (of TV-B-Gone fame) and Jimmy Rodgers (of LOLshield fame) presented a soldering workshop. There must have been 50 people around! Also Matt Mets and Dale Dougherty were here from Make Magazine. Big thanks to Mitch, Jimmy, Matt and Dale for being part of the LVL1 experience. Our doors are always open to you!

During the soldering workshop, I built at LOLShield. Nice kit – lots of LEDs to solder. Jimmy was really good at making his LEDs come out in neat little rows – mine, not so much. Here is my video

I came upon this post and decided to make an animated LOLShield LVL1 logo. I had to download python 2.6 and the PIL library and the script ran perfectly. I created an animated gif using Gimp. Set up an image to be 9X14 in grayscale. Then draw your picture (zoomed in) and animate it using multiple layers. When you save as a gif, Gimp will make the layers into a animated gif. It is not hard. Here is my gif…

It is tiny! Next run the script in the command line and then cut and paste the code. Here is the Arduino program I am using.

The BitMap array is what contains the frame data. Each line is one full frame.
Since each number is 16 bits, we can easily fit all 14 LEDs per row into it.
The number is calculated by adding up all the bits, starting with lowest on
the left of each row. 18000 was chosen as the kill number, so make sure that
is at the end of the matrix, or the program will continue to read into memory.

Here PROGMEM is called, which stores the array into ROM, which leaves us
with our RAM. You cannot change the array during run-time, only when you
upload to the Arduino. You will need to pull it out of ROM, which is covered
below. If you want it to stay in RAM, just delete PROGMEM

I had to adjust the code to keep it from blinking at the end of the animation.
