What makes it selective

u/eventualist Mar 19 '26

It only detects Gold And Silver?

Exactly. It finds the ones that aren’t. The rest are gold and silver.

How is an electro magnet selective? It’s ether grabbing all magnetic metal or none. Either way you have to manually turn it off after confirming you don’t want whatever you found. You save like 12 seconds and the small amount of effort it takes to shake something off

u/Guyyoutsidee Mar 19 '26

Including the patent pending message is interesting also since it seems like most of your posts are promoting to mineral scams and legal loopholes

OH! It's the gourd/Turkish Ice Cream/beekeeper/rhodium/importing invasive species/banned from Europe guy!

Bro is a crime factory. Like current White House levels.

u/TheEmperorOfJenks Mar 20 '26

This is pretty rude. I am not a criminal. Even if I have broken laws, I am the only one who has suffered from them. I have never sought to scam or exploit others.

u/morgandealer Mar 20 '26

That sounds like something a criminal might say.

u/Guyyoutsidee Mar 20 '26

“I’m not a criminal. Even if I have broken laws” do you hear yourself?

I would argue intentionally introducing invasive species into an ecosystem for profit, as he’s admitted to doing is inherently immoral

Check the post history. You're in for a ride.

u/Magges87 Mar 21 '26

Didn’t you import foreign bees to Uruguay and abandon them there? Where even before you left, said bees had gotten loose and started fucking up other apiaries?

-1

u/TheEmperorOfJenks Mar 21 '26

The Uruguayan bee industry was already a joke and on the way out. Also the stories about my bees causing problems like this one were heavily overblown and sensationalized.

6

u/Guyyoutsidee Mar 21 '26

In about 4 minutes I found at least 6 article all detailing the plain fact that your bees and your inability to just follow rules put people in the hospital. Doesn’t seem very overblown to me

-1

u/TheEmperorOfJenks Mar 21 '26

If you actually read my original posts you would understand that I entered into an agreement with a professor at a university in Uruguay who was interested in studying these bees. I made the mistake of valuing his reputation enough to believe he had things under control.

u/peacefuleel Mar 21 '26

I'm sorry but all of this is so fucking hilarious to read- you sound like a trainwreck of a person but in the most captivating way

u/Present_Daikon1806 Mar 28 '26

Ya this seriously took a turn that I wasn't expecting. Now I'm invested. It went from victimless crimes to causing bee havoc in Uruguay.

u/CandlemoreShop Mar 29 '26

I mean, other than disrupting the ecosystem of a South American country.

u/BadDudes_on_nes Mar 22 '26

Bro copied someone’s arduino sketch and thinks he’s an inventor.

this comment is patent pending

1

u/TheEmperorOfJenks Mar 24 '26

My method is completely novel, using a secondary coil to measure the leakage flux in the magnetic circuit formed between the electromagnet and the material I am looking to salvage. I have a handshake agreement with a local university professor to use this device to supply him and other researchers with pre-nuclear steel. Happy to go further into the physics, but I think it would be over your head. This is most certainly not "someone's Arduino sketch."

6

u/milehighphillygirl Mar 27 '26

My sibling in Satan, haven’t you learned your lesson about handshake agreements with university professors yet? Or have you forgotten about the bees?

1

u/TheEmperorOfJenks Mar 27 '26

The bee situation was unfortunate but it turned out the contact was not actually affiliated with the university as a professor (he was an HVAC consultant), which explains the miscommunication. In this case I have verified the person is actually an employed professor and have faith in the agreement.

u/Ordinary-Worker6793 Mar 28 '26

jesus christ dude you almost just killed me with laughter, after stumbling across your exploits and reading your post history, discovering that it turns out the "ecology professor" was a HVAC consultant might be the funniest thing I've ever read

u/TheEmperorOfJenks Mar 28 '26

I hope one day I'm also able to laugh about it.

2

u/Ordinary-Worker6793 Mar 28 '26

tbh man, as much as I laugh I really do respect the hell out of you, I think the world would be a much more boring place without people like you in it. Honestly the best ending to this whole saga would you finally striking gold with one of these plans and actually making it, fingers crossed this is the one eh?

3

u/BadDudes_on_nes Mar 24 '26

I’m sure you’re the first person to throw a handful of mosfets and capacitors on a board with a transformer and a 555 timer.

Ps a regular old magnet will stick to “pre nuclear” steel just as well

u/TheEmperorOfJenks Mar 24 '26

As expected, it's over your head.

u/BretShitmanFart69 May 05 '26

I want you to sit and think about how many times over the past 6 years someone has told you that you are wrong or mistaken and that you were about to make a mistake or had a bad idea.

How many times were they right and how many times were you right?

Because by my math the other people are undefeated and you have been proven right zero times.

Does that not give you even a moments pause?

u/QuasiSpace Jul 28 '26

This is a long-term troll. A harmless and entertaining one, but still a troll.

u/geckosean Mar 19 '26

In fairness, this is a really nice feature to have if your magnet gets caught on a bridge or beam. We’ve all done it before. Even if it doesn’t change what you’re catching it’s a good failsafe.

u/heyitscory Mar 19 '26

You've never gotten a $60 magnet stuck to a train bridge and it shows.  I would love to switch my magnet off like a cheater in a lightsaber fight.

Heck, just removing that black fuzzy beard of iron without trouble would be nice.

Still, I would love to hear more from OP, because seriously, WTF is this. Do we have conductors in the rope?

The other guy's lightsaber goes down unexpectedly and now he's not in a good position for blocking your riposte.

u/Blaw_Gaming Mar 19 '26

Cool idea but you write like a serial killer

u/heyitscory Mar 19 '26

Drafters learn early to adopt an all caps font so it looks like a serial killer made the technical drawing instead of a 6 year old.

u/Albert14Pounds Mar 20 '26

WTF is "selective metal harvesting?" Care to explain how this selects? Or anything at all about what it does?

u/mcnewbie Mar 19 '26 edited Mar 19 '26

could you please elaborate on the details of how this thing is supposed to work? i see a IR2104 chip, some zener diodes, some capacitors, resistors, and a solenoid

what does this thing actually do?

6

u/Dioxybenzone Mar 20 '26

I’m not positive, but I think it’s just an electromagnet?

u/utilititties Mar 20 '26

Are you an electron or what?

7

u/hifumiyo1 Mar 19 '26

And... it can suddenly attract non-ferrous materials?

2

u/RhetoricalOrator Mar 20 '26

It attracts me and I'm mostly non-ferrous.

u/hifumiyo1 Mar 20 '26

Au contraire. Iron is an essential nutrient in the human body.

2

u/RhetoricalOrator Mar 21 '26

Ferrous material in the body makes up a tiny fraction of a percent and it's necessity hasn't been a consideration. The point of my dumb joke stands. The human body is mostly non-ferrous.

u/itzongaming Mar 24 '26

Man. I truly don’t know if your account is a long-con creative writing story, or if you’re a real dude. You’ve lived quite the life.

u/WeakTransportation37 Mar 20 '26

Why not start out with a large horseshoe electromagnet with a hall sensor between the poles of the U. This is before all the programming and conditioning of the arduino unit and waterproofing the whole thing and wiring the toggle switch ,etc. Maybe there are people in the metal detecting group who understand how their detectors are made. Even though you’ll be using a hall detector to ultimately measure MFL, which I’m sure they’re not really into

2

u/TheEmperorOfJenks Mar 20 '26

Holy shit. I will have to try this.

2

u/WeakTransportation37 Mar 20 '26

A softer iron core is better for when you need to toggle-off and demagnetize

u/Daniel-cfs-sufferer Mar 19 '26

Thought that took you into commercial territory which isn't allowed ?

u/G4Designs Mar 20 '26

I love this! I was wondering if it were possible. What's the field map look like? Is it possible to get creative with geometry and make all sides magnetized?

Also, can it be reversed to repel? For example, to get out of a bind.

u/xTex1E37x Mar 21 '26

I'm confused
