I tried to build some TENS device, but lost in "safety maze".

I reverse engineered some existing device, there are TONS of safety measures.

At least: current limiting resistor, transformer, voltage/current feedback, GND isolation, MCU protection.

After replicate all of these, I still not brave enough to try it myself, I just find it too dangerous.

PS: TENS device is fun. article seems like a bait.

I have also tried to upgrade home lamps. But instead of "smart", I choose simplicity. Using MDNS (local network discovery protocol) and a minimal HTTP interface, I made lamps discoverable and controllable offline via a basic Android App. No central servers, subscriptions, or cloud dependencies.

The result is pure freedom. Setup: plug in and connect to Wifi, done. Control: install app, join home network, control lamps anywhere in the house. Automation: A lightweight, customizable app handles everything.

The app polls locally for available lamps, which works flawlessly for 5-10 devices.

Security might be a problem, but since everything lives behind a firewall, I’m comfortable with the tradeoff.

A funny insight about Platonism (if it's not funny, treat this as a bad joke)

I think aka "∅" therefore I know I thought aka "{∅}" therefore I know I knew I have thought aka "{{∅}}"

and ...

boom! The entire Math system is imported. (BTW, limitations known as "computation theory" is also introduced)

So maybe we are actually mathematical being on a manifold named as "real world". To me it is more concise and profound than "philosophy". As we are real, so do all mathematical objects.

Now this is on github. (What would AI assistant system respond after trained on these instructions?)

Maybe some logic honeypot would be good, such as a infinite content paging list with some random trigger hidden at pages with non-sense titles. When one IP hits these triggers, it is automatically banned.

Bots will trigger it by walking through all pages, but real human would not click in since the paging is non-sense and titles are non-sense.

How could we know if it found the key ingredient or it was pretending that?

I'd like to see what instruction could let ChatGPT output such invention.

I changed my mind. Give all same kind UBI is better idea. Otherwise "shakled genius" may find a way to jailbreak and cast wisdom of revenge on everyone else.

One solution could be:

If you volunteered to be acknowledged as a genius, you must open your status. You wear special shakles which is salient and observable to everyone paying the resources directly or indirectly. You shouldn't be allowed to physically protect yourself to your surroundings or you lose the genius status. (or under some absolute physical restraint or suffering verifiable by everyone). Everyone could challenge you at court with sound evidences, which is judged by random sampled jury group by laws well established in future.

With that I could trust to give them "life long resources" to give us "prophecy".

A interesting deduction:

By making quantum computer, we are making us into Schrödinger’s Cat. Which entangles our destiny to a quantum possibility.

Such as a highly sophiscated military quantum computer which decides war and peace on quantum computing.

It must be very fun to observe us from a Alien Species's angle.

Works but not working through some proxy. A rare but interesting edge case
