Does a USB drive get heavier as you store more files on it?
Nope. Paradoxically (and theoretically), the more you save on a flash drive, the lighter it gets.
USB drives use Flash memory, which means the the ones and zeros of the data are stored on transistors.
When you save data, a binary zero is set by charging the float gate of the transistor, and a binary one is set by removing the charge.
To charge it, we add electrons, and the mass of each electron is 0.00000000000000000000000000091 grams.
This means that an empty USB drive (which mostly holds zeros) weighs more than a full USB drive (which has ones and zeros). Add data, reduce the weight.
Here is a cool little gadget I'd never heard of before. It's a temperature datalogger. It lasts 60 days. Sadly I think it may be disposable (but I'd imagine rechargeable versions exist. )
Suppose you are shipping fruit across the country and you've paid extra to have the trucks chilled down to 65F. How do you know they didn't ship them at 75F and only lower the temp fully just before arrival?
Hide this bad boy in your shipment, then check the USB for data on arrival.
They cost about $4 each.
I'm fascinated by things like this for reasons I can't possibly articulate.
I almost bought one just to try it out and take it apart... but instead I'll just tell ya'll about it... I bet there are other interesting ways to use such a device. For example... you could detect if a chair is being sat in or not by putting it inside of a pillow...
Hey folks, I really don't want to stock these USBs anymore! So I'm doing a firesale on them. They're a hold-over from the time when it wasn't really doable to transfer large files over the internet.
USB 1.0 (Blue) drive contains nearly 3,000 pose reference images.
You are getting a USB port installed on your body, making you a portable phone charger. This will not have a health impact on its own (ie, no metal or current leakage or poisoning/infection)
I specify that it's like being a portable battery to make it clear this is not about being able to store/upload/download data or files. This is just like. Reducing the need for the charging block
