• Arduino

  The ArduinoThe Arduino is a small computer.  And inexpensive.  And a child near you should have one for whatever holiday comes up next, but you should get it out of the box and play with it first. There's plenty of online support for the hardware and the development system. This project will connect an Arduino to JMP and do some real time data logging.  You'll need the Arduino IDE download; here's...

• Color Video

  This video takes a trip through RGB color space.  Inspired by RGB Values to Color Names in Data Table and RGB Color Matching Script, I used JSL's KDTable function to make a sequence of bitmap slices of an RGB color cube showing the closest X11 color name for the pixels in the slice.  Made with JMP (and some other video/audio tools).  KDTable will be the topic of the next post.No Cyan (YouTube vide...

• Factory Art

  Not-quite-random art generator.  Notice the paint function's use of matrix indexing to avoid an explicit JSL loop to set a vertical line of pixels, more-or-less perpendicular to the path of the brush.  M selects the pixels and blend1 & blend2 make the center of the wide brush stroke opaque and the edges more transparent.  (Off-shoot of another project, inspired in part by Dynamic Image Generation ...

• Files In Directory

  This example uses Files In Directory to get a list of all the files in a directory.  It then looks for all the .jmp files, opens (and later closes) them one by one, making a summary table along the way.  The $sample_data directory has sub-directories which will be in the list but are skipped by the EndsWith test.  EndsWith is case sensitive; you might want EndsWith(LowerCase(filename), ".jmp") to ...

  Scroll to the end if you just want the video. 
  I've done some minimal testing of this JSL on Mac and Win, in JMP 11 and 12.  The video takes advantage of features in a future version of JMP, but don't let that stop you.  Add a comment here on your experience.  The JSL is in the attached ZIP file.
  
  This post touches, lightly, a bunch of topics.

• Wall Paper

  No video this time, it seems to move all by itself.  The JSL, attached below, is the first step in another project.  It demonstrates drawing into a matrix (circles and text), displaying the image on the screen, and, commented-out at the end, saving the image to disk.  The different size circles (nib is an old term for the part of a pen that touches the paper) are pre-rendered into an array.  If yo...

• Glitch

  
  Personal project, just for fun.  How much does the power line frequency vary?  If you do a little web searching, you'll get a bunch of answers, all of which say it varies, but with a lot of disagreement on how much, when, why. 
  Here in the US, the nominal frequency is 60 Hz and the nominal voltage might be 120 RMS Volts.  The electric utilities on the east coast (Eastern Interconnection - Wikipedi...

• Tile

  Found this generator for aperiodic Penrose tile, makes a pretty picture.  A JSL implementation should use recursive function calls to make it faster; expanding the string of symbols gets really slow for a really big tiling.  Using transparency shows the generator code makes the same lines more than once.  There is 5-way symmetry around the center.  This is an 8-level deep recursion.Update: another...

• Load Compressed Data

  Just had a request for a way to move data from an external program into JMP.  Generally I'd recommend using CSV files for this, but if compression is an issue, maybe something else is needed.  Here's a couple of proof-of-concept scripts (you'll need to make sure they do what you need).  Since I don't have an external program, each script is in two parts: create a zip file from a table, then recrea...

  Playing with WordNet and CMUDict (again).  Starting to look interesting.  The rhyme information is from the pronunciation dictionary.  The drop-down in the picture contains more relationships than just synonyms (other WordNet files).  The numbers to the left of the lines in the poem are syllable counts, more-or-less.  Some words are not in the tables.  And I'm making a guess that every syllable ha...

• UTC Time Zone

  Your computer's clock shows you time for your local time zone.  You probably know your time zone as a three letter code like EST (Eastern Standard Time) or EDT (Eastern Daylight Time) or maybe GMT (Greenwich Mean Time).  GMT has several other names: UTC is a compromise acronym for scientists and Zulu is a military designation (Z, for zero). 
  GMT has an offset of zero; EDT is GMT-4 and EST is GMT-5...
