Ask Slashdot: What Interesting Things Can I Power With an External USB Battery?

New submitter expert464 writes: I just purchased an external USB battery for the main purpose of charging smartphones. I've also thought of using it to power a USB lamp and charge a bluetooth speaker. What other things am I missing that would be useful and/or interesting to power when not near an electrical outlet? Have a question for Slashdot's readers? Take a look at other recent questions first to see if someone else has had a similar question. And if not, ask away! The more details and context you include, the more likely your question will be selected.

    I use mine to power a digital picture frame so I could actually hang it or place some place that having a cord to it would look bad.

  6. BlinkyTape or a similar LED installation by kav2k · · Score: 3, Interesting

    You could look into LED decoration. For example, BlinkyTape - a LED strip with an attached Arduino-compatible controller.

    It can be just decoration, or you can use it for light painting.

    Of course, you can build your own LED-based contraption.

    I've seen some idiotic "Ask Slashdot" stories, but this one probably takes the cake. To use the ever-popular car analogy, it's like asking "I just realized my car has a 12 volt electrical receptacle in the dashboard, what sort of things can I plug in?"

    Yet another "Ask Slashdot" that can easily be solved by Google.

    Hey everyone, I just bought a bottle that I can attach to my bike so I can drink water while I'm riding my bike. What other drinkable liquids can I put in it?

    Also I just bought some AAA batteries for my TV remote. What else can I put them in?

    You'd think Dice would have learned about the damned Streisand Effect from all the stories here on Slashdot. All it would have taken is a single line: "Disclaimer: Sourceforge is a wholly-owned subsidiary of Dice Holdings, Inc." in the summary. Major news media outlets do this *all the time* when reporting on (either positive or negative news) their sister organizations owned by the same umbrella corporation.

    The topic would have been done, discussed, and on it's way to being forgotten by now. Instead, you simply get a slow burn of news and a bunch of people irritated at your obvious and ham-handed suppression of a story.

    Note: Sorry for the offtopic. Consider it a small act of "civil disobedience."

    "Existing evidence indicates that EC use is by far a less harmful alternative to smoking. There is no tobacco and no combustion involved in EC use; therefore, regular vapers may avoid several harmful toxic chemicals that are typically present in the smoke of tobacco cigarettes. Indeed, some toxic chemicals are released in the EC vapor as well, but their levels are substantially lower compared with tobacco smoke, and in some cases (such as nitrosamines) are comparable with the amounts found in pharmaceutical nicotine products. Surveys, clinical, chemistry and toxicology data have often been mispresented or misinterpreted by health authorities and tobacco regulators, in such a way that the potential for harmful consequences of EC use has been largely exaggerate"
