What is a Watermelon Ice USB Widget?

scottiebabe over 2 years ago

While cutting the grass I found this USB-C widget laying out by the curb. The nerve of some people to toss their e-waste on the side of the road!

hmm... I know nothing about these kind of widgets...

Inside there is a 600 mAh li-ion battery

Beyond the battery and maybe the USB-C connector, i'm not sure what else is worth keeping.

I haven't tested the battery yet, but I have just the USB widget for that task!

    So what did I end up with, well: a) An interesting story b) An interesting sensory experience from the smell c) A genuine ~600 mAh li-ion cell Perhaps I'll use the pcb as a usb-c power source…

    The battery inside claims to have a capacity of 2.41 Wh In a 16350 form factor It doesn't appear there is any dedicated battery protection circuitry. The widget is solely relying on the charger…

    When I worked at a Tropicana juice plant, one of the ladies working in the QA department could, by smelling and tasting the finished product blindly:

    • tell where the oranges came from. Florida, Brasil, elsewhere
    • how long ago the juice was bottled
    • stored in a glass or plastic bottle
    • how much sugar

    Maybe you can become the same expert in the vape industry :)

    lol That's pretty impressive!

    Even though this isn't my thing, if this get someone into electronics I think that is totally awesome! It would seem there is a DIY vape community

    I think that is awesome!

    100! Was that by chance or by design, that really neat!

    BeagleBone
    Announced in the end of October 2011, the BeagleBone is a barebone development board. 
    It can fit inside an Altoids tin.[32] The BeagleBone was initially priced at US$89

    I believe it was an intentional design choice. At the time, both regular and mini-sized Altoids tins were very popular enclosures. Adafruit had several products/accessories for them (like a protoboard.)

    I have a unpatented blast proof shield storage box dedicated to them. Around 2011 I was eating the mints like candy, so I started saving the boxes to use as projects enclosures. (Which, to date, I have not yet done.)

    It was intentional. There's an early AmpHour podcast, where the designer confirmed that.
