|HBR 14 coils conversion to toroidal coils||cathoderay||on 21/3/15|
|I built some coils for non-radio purposes. I used the formulas from a book called, "LC Circuits". It's not very big, but it's really clear and concise. I bought cores for the freqs I wanted, then ran the calculations per the book. Wound them and tested them with a scope and variable oscillator (and precision capacitor).|
|Field Soldering Without A Soldering Iron - Video Link||KF4HOJ||on 2/3/15|
|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.
|How to Build A Portable Solar Power Supply Video Series||KF4HOJ||on 2/3/15|
|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.
Part 1 - Intro & Background
Part 2 - Power Output / Battery Matching
Part 3 - Solar Panel / Controller Matching
Part 4 - Building Tips & Tricks
|Ground Rod Driver Tool - DIY||KF4HOJ||on 27/2/15|
|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||on 27/2/15|
|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.
