Build your first Djed
Seriously. If you were hanging on my every word, then you should email me. And if you understood half of it, you should write your own papers and I'll read them! This puzzle isn't for everyone, and that's ok. But it is for you.
In 1975, I estimate about 5,000 people in the world would have had interest in helping Steve Wozniak build his first Apple computer (2,000 of those were IBM, Tandy, and Xerox employees). Fifty years later, we're all taking advantage of it.
This community is for the trailblazer. Our success is assessed when inertia tools are useful to the mainstream.
I've been at this alternate ancient methods search for a long time. It's curious the sort of mental diocese-freeze we get into when thinking about this technology. Me included.
When I tell people Djedzilla could be our technological missing link to a forgotten technology, there's an expectation that I've pulled out Excalibur. Spoiler Alert. The first wheel probably wasn't round and my Djeds are not perfect... yet. Nor do I really know how to effectively use it... yet. This is why I'm asking for help investigating this technology.
Nonetheless, when I ideate with people on what it should look like, I notice we somewhat box ourselves into our perceived notions. Top-down product design is rarely effective. Now imagine being top-down from +10,000 years away. Djedzilla approaches the ancient tools problem from the bottom-up.
Not per se, but some one out there cares. But really, it starts with making a widget from a coat hanger, two slinkies, and a rope. You don't need any equations to explore HOW the concept works. You can get deep into the physics if you want to know WHY it works. Otherwise, just have fun with it.
While Djedzilla seems like a toy-like widget, once you increase the mass, tighten up the springs, and tension it taught to an inertial frame it transforms into a precision jackhammer. Couple that punch with resonant amplification, and voila, you have a very effective tool for splitting rocks and such.
Beyond that, the mechanical oscillation amplification characteristics demand our attention. The Djed is also the fundamental mechanical oscillator for the Ankh design.
From what I know of Ed's backstory, he was from a family of masons and he worked on the railroad. As for me, I'm not going to build larger than ~500 lbs until I've gone to Coral Castle and kicked the stones around the yard. Increasing the scale also increases the engineering calculations... and the risks to my safety. I'm not sure where the Egyptians stood on OSHA compliance, but I'm a fan of keeping my fingers and toes.
Let's understand this phenomenon on the Djedzilla / Slinky level. Then we can scale it up once we demystify the nuances.
The fundamental geometry and governing equations have been established. Djedzilla represents a cost-effective, repeatable, and safe design for initial development. I hope you each discover a method of attaching a flywheel and we can commonize on the best configuration. There are many solutions and I'm curious which you select.
The 20-ton monolithic block to an ancient's engineer is a high-energy particle accelerator to today's physicist. Therefore it's fitting we start with Djedzilla, the equivalent of a 'my first physics kit'. Let's start small and standardize. Repeatability is the key, not more energy.
