Old inventions - new episodes?

There was a gas powered pogo-stick made in the 60's.
It was called the Hoprod.

Powered Pogo Stick....
I think I just found something ELSE that may trigger my strange Vertigo.....

Until the late 80s, there used to be an "industrial" version. Just attach motorcycle style footrests and you have a toy


Those things are highly inefficient and real dangerous. They now use vibrations only, much quicker, does a much better job and almost not dangerous at all. But the old kind with footrests attached… I WANT ONE!

Nope, that's not one of those 1000lbs "pogo sticks". Those vibrate and do a much better job in a much shorter time. I know, I once worked for the company which invented this design you see in the video - it's a rivalling company in the video.

The vibration allows the sand to settle and all the air comes out. If you just jump on the sand, the inhertia of the sand prevents a good job. Also those modern machines are much more lightweight - at least the company I had worked for made - I can carry them just fine and put them onto a trailer or into a van. The 1000 pound "pogo sticks" were quite a problem, usually they came with special trailers but getting those things into a trench to work inside was a serious problem, especially getting them out without squishing your feet!

The trick while operating those things is to lean forward to protect your feet - but not too much or it hits you into your face or trips over. The modern lightweight vibrating machines can be pushed like a shopping cart while running so you can just walk them to where you need them with up to 2mph.

You picked the wrong manufacturer then. "Ours" are designed to be easy on the operator. I remember hours of test drives with g-force sensors and microphones.
The latest design I took for a spin was much easier on your hands than my old lawn mower! They also move forward or backwards on their own, even on steep slopes. And the expensive ones even tell you how hard the ground is and speed up or slow down automatically so you get an even result with your desired specifications in a minimum of time. The main problem is when you run over something hard in the ground like a concrete pipe or old foundation wall, the vibrations can be reflected and rattle the ground loose. The "inteligent" machines sense this and adjust them self.

I watched and it vibrates, it doesn't jump, just look at "my" video, this one jumps and has half a ton in weight!

In "your" video, the advertised "automatic oil check" comes with the Honda motor they use and it doesn't work well. All it does is to short out the ignition if the oil sensor isn't submerged. But it can only sense for no oil when the machine isn't running and far beneath MIN level. If you manage to start it "on the last few drops", the machine can run dry easily and won't shut down on its own any more. Also if there is no oil inside and you don't notice, you just wonder why that §$!"§$!"§$ thing won't start, it gives you no clue why! In "our" machines, I included a "check oil" light which flickers during your starting attempts and it is real bright and "eye catching", you can't miss it and it lets you know why the machine refuses to start. Doesn't fix the "run dry" problem if you have a leak but that's the problem of the Honda engine. You should buy the Hatz DIesel version which is a lot sturdier and has more power while it is even a little lighter!
Also when the machine is fully worn out and falling apart (material fatigue, no miracle there considering what those things do), the Hatz Diesel is still good and you can make a neat Diesel generator out of it.
