Inexpensive nano power comparator needed

Thanks piglet. Very nice circuit. I like the multivibrator and current limiting driver. Very simple and very elegant. I will save your circuit for future reference.

(BTW, I had to sign out of google to test the link. Now google wants me to sign in with my password every time I log in. I fixed it by saving the cookie after signing in. Now google stops complaining. I did the same with eBay and it also stopped complaining. I reload the cookies every time I reboot, so the file doesn't get clogged with cookies from other sites.

I will have to figure out how to share google drive links without going through all this mess. But all the other file sharing sites have croaked or have much worse login problems. I will have to see if I can get Dropbox to work, but I definitely do not want it uploading all my other files to the cloud. Hopefully I can find a solution that everyone else can use. This would make it easier to upload LTspice files without having to post the ASC and PLT files to the newsgroup. That is such a pain, especially when you have to deal with line wrap problems caused by news clients.)

I tried to install the free version of Dropbox:

Get started by downloading Dropbox on your computer. Set up Dropbox Update your computer To run the Dropbox desktop application, you’ll need Windows 7 or higher. First problem: I am currently running Win XP.

Second problem: I do not need to download a program to simply upload a small zip once in a while. I do not need the hassle of learning another program with all its hooks and traps. I do not want a program that has the capability of uploading all my files if it is not configured properly. This has the potential of uploading garbage if a file is corrupted, which would destroy my backups.

I don't want a program that can destroy itself if an update is corrupted. Microsoft is the perfect example of what can happen with automatic updates that destroy files or shut your system down, and Dropbox has incorporated unpopular changes without recourse. I have other more secure ways of handling backups and I don't want a Dropbox style program in my system.

Two other file programs that used to work are now broken or have gone intermittent:

Sabercat:

Even with the file sharing glitch, Google Drive appears to be the best available option. If there are other file sharing programs I am not aware of, please let me know.

There are advantages to having files "disappear" after a while. I rarely want to leave something available (on a server that I don't control) for very long.

I've used Mediafire intermittently, in the past. But, it has a 10G limit on free accounts (which is fine for me as I only push things to that site when I don't want folks accessing my server). As it is entirely web-based, there's no software to install on your computer (besides a browser).

And, YOU have to explicitly "upload" content so no fear of "it" deciding to harvest stuff from your machine.

I've played with Mega NZ in the past. I'm not sure if you can use it without their "helper app" (it's been a while)
