AgIC Circuit Marker Set

It works well.

It is a great product. It works perfectly. The only limitation is the kind of paper. You cannot use any paper for this pen. You have to use photo paper or something similar.

One of my students found this and I had to buy one. So cool!!

the pen drying.

This is an amazing tool for paper circuits projects. You literally draw circuits on a piece of photo paper and then add the battery and LED lights (or other outputs) and BAM! - you have a working circuit. You no longer need to wait for the ink to dry or have to deal with copper tape that curls and bunches up.The marker lasts for quite a bit - I've used them in several workshops and its still going strong. The only thing I recommend buying in addition to this is  CR2025 Tabbed Replacement Save Battery  - basically a coin cell battery with leads so you can just plop them down onto you circuit without having to bend one of the corners of the paper.The company is also now selling printer toner that will print circuits using their special ink so you print out circuits and use them for creating gorgeous murals, posters and signage.

It's not so conductive.

LEDのセットと一緒にXmasプレゼントで子どもにあげました。試行錯誤しましたがなんとかつきました。紙が足りないので買い足します。
