I'm using this barcode scanner,

There are similar products from other brands as well.

This is very exciting. This makes me want to try one of these out for a movie project. I noticed on the Arkstone website that:
"ES201s will be discontinued, and replaced by new model AS202 which it only supports Android devices.”

Which are you using?


An interesting aside from the historic land of film—in order to find shots amongst a sea of frames, professional film stock has employed various “edge codes” in both human readable and barcode form. Automated systems can pick up this metadata during film scanning/digitization and automatically add this information to database. After editing digitally, the database can be used to partially automate the re-assembly of the original film.

I did a quick prototype of the presentation part of my memex idea using barcodes.



I added small barcodes to a printout,

<2016-03-30 18.23.13.jpg>

and I'm scanning them using this gumstick-sized bluetooth barcode scanner (it acts as a bluetooth keyboard),

<2016-03-30 18.39.13.jpg>

The barcodes themselves measure about 1/2" by 1/4". They are EAN8 codes generated using this javascript library (github) and this script:

<html>
<head><title>Barcode Generator</title></head>
<body>

<script src="JsBarcode.all.min.js"></script>
<script>

function appendBarcode(id) {
  // Ensure 7 characters, left pad with 0s.
  id = ("00000000"+id).slice(-7);
  console.log(id);

  var img = document.createElement("img");
  document.body.appendChild(img);
  JsBarcode(img, id, {
    width: 1,
    height: 25,
    format: "EAN8",
    fontSize: 12,
    textMargin: 0,
    margin: 4
  });
}

for (var i = 0; i < 30; i++) {
  appendBarcode(i);
};

</script>
