Field Soldering Without A Soldering Iron - Video Link KF4HOJ 9 hours, 32 minutes ago
Video about how to do field soldering without a soldering iron, using matches, lighter, ... I tried many ways (and failed) until I found this simple trick about using the wire as it's own soldering iron.

These are links to 4 videos (basic level) I made on how to build a portable solar power supply (aka "generator"). Thought some might find it useful.

Ground Rod Driver Tool - DIY KF4HOJ 3 days, 9 hours ago
This is a video of how to make an inexpensive ground rod driver tool. It allowed me to put in a 3 meter long rod in just over 2 minutes flush against a wall. No mushrooming, no smashed fingers, no collateral damage (do know if there's anything underground before you drive!!!) I stopped about halfway down and got out a small sledgehammer to compare the difference and quickly went back to the driver tool.

It fits on the end of a hammer drill. I have just a smaller size hammer drill and it works fine. Hope it's useful.

Grab N' Go Solar "Generator" Box - DIY KF4HOJ 3 days, 9 hours ago
This is a video I made of a grab and go solar power box. I made it for camping (powering gear, lights and such) and for our frequent power outages around the house (which is shown in the video).

The box is from a company that makes emergency lights (the ones you see in buildings for when the lights go out) and the rest is just common stuff. The controller can be bought from Amazon. The panels are just 1-2 40 watters.

The output plugs I chose are the common car cigarette lighter plugs since you can buy literally hundreds of different things that fit them and most hams have used them in mobile applications.

I have 4 more videos on the basics of putting one together.

Crystal Radio DIY Video KF4HOJ 3 days, 12 hours ago
I put together a crystal radio with my son to show him the basics of radio. I've shown it around to a few people I know and they were all very interested (1 person has already completed one himself for his kids). I put a video out on youtube showing the steps. It's modeled after the old Wolf Scout radio they had in their handbooks when I was a kid.

Here's the link:
