I just found and had a chance to play with the 555 simulator over the internet. As I do a lot of designing and use the 555 in many of my projects, this tester is a really handy tool.

Is there a way to get a copy of this simulator that will simply run on Windows? If not, how about running it through Internet Explorer?

I realize I could simply put a link to your site and use it that way, but I don’t always have a connection to the internet. Basically, I would just like to use this little applet on my laptop on my bench at home.

Thanks for your help, and congratulations on such a cool program.

Hello again,

Thanks for your quick reply. As I don’t have a website nor a blog, I was hoping that the 555 program could be just a stand-alone application. Is this possible?

Your program is really nice, so I hope it can run as a small program by itself.
