This is an update to the Das Blinken Board from N&V June 2009. Der MagnetFelder uses a hall effect sensor to determine the relative strength and polar orientation of magnets.

Some tonemap and hdr images I did from Friday night’s DorkBot event.

Some interesting things have happened Since May of last year when I wrote the “Color Match” article.

  • If you do a google search right now for “Classical Art” the article comes up as the 7th natural link.
  • According to my logs over 400,000 people have seen the article.
  • People have posted blog articles about it at least 6 different languages.
  • The content of the article is now being heisted and put on “Scraper Sites” using tons of my bandwidth by hot-linking the photos.
  • I get great feedback from people using the technique.
  • I think the coolest thing about it is: Sometimes when I meet someone for the first time; they have already read my article.

These are some of the first photos I have ever released under Creative Commons Licenses

Some time ago I went on a glue buying freak-out. I needed glue for a particular project and realized that we were really understocked in general. So I went over to the office supply store and bought about 4 different kinds. They all have their uses but the one I keep finding new uses for is the “ELMER’S® Glue-All™” pens.

They seem to just contain the normal white glue but the real advantage of these things is the applicator tip. Just squeeze and out comes a drop of glue. I sometimes use the tip to help spread the glue around. I don’t have a caliper small enough to measure the inner diameter of the tip but it is about 1.5mm diameter.

Another thing that has impressed me about these pens is that I have had one ‘active’ for at least 3 months and it hasn’t dried out or clogged yet. The cap seems to make a really snug connection.

I haven’t tried it yet but the applicator tip unscrews from the pen part, so theoretically these things could be re-filled.

A pack of 4 cost me less than $1.50 and each pen holds 10.5mL of glue.

I have just posted my howto article about using classical art to make expert color corrections to photos.

This is a hdr tonemap from a single jpeg. As you can imagine heavy color manipulation and such.

I have been going through my photos that I took in my 2005 trip to the Languedoc region of France. Looking for ones that could be improved by tone-mapping. This photo is one that I would have overlooked but it’s now rescued.
