I was attempting to teach fishing lessons. However, that works too. 
Holy cow! What a great idea! I am going to make these for my family and my neighbors. Thank you!
Edit: Hmm. And maybe spray with Rust-Oleumās Specialty Metallic Copper spray paint. I believe it actually has some copper in it, which would perhaps be a little anti-viral.
Completely missed it! Thanks
For only $25, you can have one tooā¦

$25 AND a two month wait (if he makes his deadline).

Part of me wants to machine those out and sell them for 2 bucks.

ShrugPlasma cut out of 3/8 brass and tumble polished It would certainly pay for the equipment and materials, and then sold on TV for the ālow priceā of 19.99 it might be the new āpet rockā. But the sales window would not be a lot bigger.
Even if it wasnāt a flash in the pan, thereās no real hurdle for the Chinese factories from churning them out by the millions & undercutting the price by 50% before you even got to market.

Always true, though might be a hair slower now.

I invented something to allow people to walk around heads down texting with their smartphones without bumping into things (or people). A hybrid hardware & software but when I looked at the barriers to replicate I figured it wasnāt worth my time to develop it and create the market because theyād replicate it and be selling it for $9.99 before I got a decent return.

A short range sensor like they have on cars now? Would be useful for blind folks.
nice! Iām afraid that Iāll make it, have it with me and forget to use it!
Not entirely - much simpler - but I did work on something like that last year for a guy who came to our makerspace looking for someone to build his patent so he could help blind people navigate the world. Turned out he had an idea and had someone file a provisional patent application but had no actual concept how to build it or what the components might need to be or any funding or understanding that an application does not make a patent (or that the existence of a competitive commercially available product likely squelches any hope of getting said patent).
Had fun working with miniature distance tracking, GPS on a chip, range finders, etc.

There is far too much of that. Having an idea almost anyone would think of but getting it through the patent process. I was playing with an inertial drive idea and it was a couple years of trying before someone could explain why it would not work. Several times since I have seen folks announce what I think was the same obvious concept, and promise to change the world and never be heard from again.
