Backpack ‘Ducted Fan’ Hoverpod

I suppose that I have been dreaming of flying since my days of watching ‘Sky King‘ on television, or of winged flight as did ‘Icarus‘ (but not too close to the sun), in Greek mythology. That was decades ago, but the dream has not faded.

I am getting closer to flying above the water on my Hammerhead Flyboard (Flying on a Hammerhead Shark), which possibly could happen in 2026. Lately, however, an older thought has been haunting me. The thought of really taking to the air.

Years ago, there was a company called Future Horizons. They offered all kinds of plans for interesting technology that you could build in your garage.

One such plan was for a ducted fan flying machine, as shown below. Now whether this will actually lift me off the ground is debatable, but such crafts currently do exist, and are incredibly expensive to purchase. They are also known as ‘widow makers.’ I’ll let you ponder that idea. This homemade craft could be built for under $5000.00 dollars.

The ducted fan is a shroud surrounding a propeller, which increases the thrust compared to a propeller in open air. Lift is developed just as on an airplane’s wings, by varying the velocity and pressure of the airflow within the duct. Essentially, a lower pressure is created in the upper portion of the duct, as compared to a higher pressure below (Bernoulli’s Principle), while the propeller pushes downward providing thrust. The combination of the two, provides lift.

If you can imagine me as a Lego character, this would be me airborne.

All kidding aside, I will probably never make this craft. If I did, it would take quite a bit to learn to fly it. A special structure would need to be built, with safety tether lines attached, while I practiced. However, I can still dream about it!

Speaking of fans, I know one person who’d be very happy if I’d get the new ceiling fan installed. I told her that I’d have to climb a ladder, and that is very dangerous for older guys!

Somehow, I don’t think she’s buying it.

Happy landings!

Airband Radio Build

From out of the clear blue of the western sky comes Sky King.” When I was a kid “Sky King” ruled Saturday morning television. For those of you too young to remember, Sky King was a radio show first, and then a TV show, about an Arizona rancher who owned a cool plane (the Songbird), had exciting adventures, and caught bad guys.

Last year, I could not resist buying a piece of nostalgia – I bought a Sky King model airplane. I also bought an airband radio, which picks up local aircraft to tower communications. Both are kits and I figured that they would keep me busy. I thought that it would be kind of fun to hang the model from the garage rafters, while listening to pilot-to-tower chatter.

Well, the model is still in the box, but I have taken on the radio. This is a $16.00 kit manufactured in China, so not a big investment. You have to put it together and figure out a few issues with the schematics as well. There are a number of these kits available for purchase on eBay.

I laid out my tools and the electrical components, and the build began.

Mostly, you just follow the layout diagram, solder, and hope that you have received all the parts. I was missing one from the kit, but was able to substitute from my own inventory.

I also had to consult the web for help. I found a radio tech who had done a video on the same build. There were a couple of tips in the viewer’s comments that helped me out. Always consult the web for help.

Here is the radio just about completed. The aluminum case does come with the kit. Actually, pretty nice.

I also consulted the web for an antenna design. You can’t pick up radio signals without an antenna…

… but that’s another build and post!
