    DIY cell phone battery replacement

    Last Saturday, when I got home  and took my cell phone—a moto g6—out of my briefcase, I noticed that the back glass had come loose. It had been in a
    hot car, and I thought that the heat had loosened the adhesive holding the
    back glass onto the phone. A closer inspection, though, showed that the
    battery had swollen, and thats what was forcing the back glass off.

    I called a couple of places to see if they could replace the battery, but neither had the battery in stock, and one wanted $50 for the repair, while
    the other wanted $100! Neither of those options appealed to me, so I
    searched for moto g6 battery replacement. One the things that popped up was this video:

    That looked simple enough, so I decided to try it on my own. Next stop:
    Amazon. I search Amazon for motorola hg30 battery and turned up a little
    over 20 items. The battery I selected was the Motorola G6 Battery, Euhan 3200mAh Internal Li-ion Polymer Replacement Battery for Motorola Moto
    G6,Moto G5S,G5S Plus XT1806 XT1925 with Repair Screwdriver Tools [24 Month Warranty]. It only cost $16,70, and it even comes with the tools you need
    to do the job.

    It took me a little over a half hour to remove 17 small screws, pry out the battery (this was the hardest part of the whole operation), and screw it
    all back together again. I didnt even have to apply any new adhesive to the back glass. There was enough remaining to hold everything together.

    $6 desk mic
    A $1 LED desk lamp from Dollar Tree like this one lets you build a desk mic
    for less than six bucks.

    I found this article in todays email from Nuts and Volts. Using a $1 LED
    desk lamp from Dollar Tree (shown at right) for the base, the author shows
    how he was able to keep the cost to under six dollars.

    He notes, No one will ever mistake my $6 desk mic for a $5,000 Neumann microphone or even a $500 Heil. However, I believe it complements the
    MicroBITX transceiver case I crafted from printed circuit board material,
    and it gets good on-the-air reports.

    3D-Printed Weather Stations Could Enable More Science for Less Money

    Researchers at the Argonne National Laboratory tested an inexpensive three-dimensionally (3D)-printed weather station, comparing its accuracy to
    a commercial-grade counterpart over eight months. University of Oklahoma scientists printed more than 100 station components from durable plastic,
    using guidance and open source plans from the University Corporation for Atmospheric Researchs 3D-Printed Automatic Weather Station Initiative.
    These parts were combined with low-cost sensors. Despite signs of equipment degradation and failure about five months into the experiment, the
    3D-printed stations temperature, pressure, rain, ultraviolet, and relative humidity measurements were comparable with those from a commercial station
    in the Oklahoma Mesonet network. Said Argonne’s Adam Theisen, “I didn’t expect that this station would perform nearly as well as it did. Even
    though components started to degrade, the results show that these kinds of weather stations could be viable for shorter campaigns.”
