I am currently working on a 40x8 scrolling dot matrix display driver based on arduino. I need to design some custom fonts in binary format for that. I looked around the web for a tool and found some excel based tool which are not very quick and easy to use. So I came up with this javascript based 8x8 pixel font generator. Hopefully it will be useful for others too.

Just click on the segments you want to light up. Clicking two times will turn the segment off. The binary font code will be auto-generated on the right. Reset button with reset all the segment status to off.

This tool and a 80x4 matrix image code generator is available on the Tools page.
