How To Of The Day: The Basics Of Soldering
Adafruit has some excellent tutorials and videos that go into more detail.
Soldering electronics is a delicate art. If you’re just getting started learning how to solder, this handy reference chart can help you spot some common mistakes and make sure your work comes out right.
The chart above from Adafruit is no substitute for a proper tutorial (though they have some of those as well), but it does pack a lot of information into a small space. When you solder a joint, you want to heat the pin and the pad for 2-3 seconds before you introduce your soldering material. If you don’t heat a part enough, heat it too much, or don’t add the right amount of solder, you can get some wonky looking joints. The right side of this chart shows how your joints might look if you mess up and what the problem was. The left side, meanwhile, reminds you which tools you should be using. For example, you should never use a soldering gun for tiny, detailed electronics work.
How To Of The Day: How To Survive A Fall Through Ice
Learn a life-saving self-rescue skill essential for all outdoors people who venture out into winter. By learning how to reduce your cold shock and get yourself out of the water with these techniques, you can save your life or help someone who has fallen through the ice to save theirs. This technique is designed for use in still water, such as a lake, and will work even if you are wearing bulky clothes. It allows you to move your body up onto ice that cannot support your standing weight, and teaches how to move over the ice until you reach ice with weight-bearing capacity.
If you are wearing skiis or snowshoes, you can first move through the cold shock portion of your self-rescue, then calmly attempt to raise your legs through applying even downward pressure with your arms on the ice shelf and arching your butt upward, followed by extending your legs out behind you. If successful, gently pull yourself forward. If this is unsuccessful, you must attempt to remove the skiis/snowshoes, or if necessary to save your life, your boots.
Cold water immersion is a potentially life-threatening situation. Do not attempt unless under professional supervision. This video was shot at the ReWild University training grounds in Wisconsin by a highly-trained wilderness instructor with rescue staff in attendance.
