Quick Tip – Buying Coin Batteries

I went to Walgreens last weekend to buy two LR44 batteries (the ones about the size of a thick aspirin) for a cat laser toy. Looking through the wall o’ batteries I found them – at $5.29 each!

I thought that was rather excessive, so instead I looked around to find the display of cheap book lights that run on LR44s. And since it was stocking stuffer time, I found a whole endcap of such items. So for $5 I bought TWO new keychain lasers that ran on three LR44s AND came with three more spares, a total of twelve batteries for $5!

For future reference, American Science and Surpus sells 10 LR44s (AKA AG13) for $1.95, plus other coin batteries (e.g., CR2016 and CR2032).

You are probably shopped out, or else trying not to go near any more stores before the 25th – so just a few items this week. Go home, hug your significant others, let people know that you love and appreciate them.

While cooking last week I realized yet again that I don’t have a decent food thermometer. This one won’t deliver until next May, but yet another thing you can do with your iOS or Android device:

Transferring Files To Others

I’ve recently shown you how to share files among your various devices. But you probably will also want to share files to other people. While your first thought is probably to send them a file attached to an email, that is not always workable for several reasons, including:

  • the file is just too big for your or their email server’s limits (usually over 5 MB is problematic).
  • the file is of a type that their email server prohibits in order to avoid the delivery of a virus (usually files ending in .exe, and frequently in .zip)

If the intended recipient is someone you see in person, you can always put the files on a flash drive or burn to a CD or DVD and hand the device/disk to them. But in many cases the recipient is not local – what then?
