On Chrome, you can manage the appcache at chrome://appcache-internals/. Web apps can offer updates when the appcache changes on the server by inserting the following Javascript on the main page:

// on page load.
window.addEventListener('load', function(e) {
  //Check if a new cache is available 
  window.applicationCache.addEventListener('updateready', function(e) {
    if (window.applicationCache.status == window.applicationCache.UPDATEREADY) {
      // Browser downloaded a new app cache.
      // Swap it in and reload the page to get the new version.
      window.applicationCache.swapCache();
      if (confirm('A new version of this site is available. Load it?')) {
        window.location.reload();
      }
    } else {
      // Manifest didn't changed. Nothing new yet.
    }
  }, false);

}, false);

Note: To trigger the update, the .appcache file, not the .html page, must change. After changing the page, just edit a comment (perhaps include a datecode or version number?) in the .appcache file.

Hi. I don't really understand much about drivers and motors. I'm going to be making a barndoor mount for astrophotography. the load will be about 2.5-3.5 kg.

currently i have no stepper motor, no driver, no gears. i think the r
threaded rod i'm going to use is for 1 rpm.

i found some motors online:
unipolar 4V 1200mA, 200 steps, 3.17kg/cm, nema 17
unipolar 3V 2A 5 wire, nema 23, 200 step
3V 1.7A 400 step 4.5kg/cm
4.7V 1500mA 200 step, nema 23, 5kg/cm

will these work? what are the ideal specs for my usage?
as for your driver, on your site somewhere you mention a version of your driver or chip suited for astro tracking, but i that i need to provide you with the gearing so you can program it? what gearing will i have? don't know this now! i just can't get started with my project because of these unknowns! please guide me! thanks you for your help.
