I finally gave in and ordered 200 small but strong magnets to up my 3D printing game to cool gadgets that can open and close with the power of invisible attraction :)
Concentration of measures:
Talagrand's "work illustrates the idea that the interplay of many random events can, counter-intuitively, lead to outcomes that are more predictable, and gives estimates for the extent to which the uncertainty is reigned in."
Trolls live in the weird space of lies, stupidity and cruelty. The inverse of what I call #LiberalValues, the personal qualities a culture needs to cultivate to make democracy work well: integrity, curiosity and empathy.
Like all trolls, you never know if #Trump wants you to think he's serious when he is not, or he just has no idea what he's talking about. He's always trying to get attention and raise up his supporters by making others feel bad or confused. It breaks public discourse. #magnets
I want to make a magnetic switch where if a piece of iron is touching two magnetized surfaces, it completes the circuit, and a micro controller notices. I think I can make the surfaces from nail heads and magnets in a 3D printed housing. Is there a good way to attach hookup wire to a nail? Solder? Crimp? Other?
@Siff The electronics are assembled now. Not the cleanest, but acceptable.
The metal plate is a cover for a ceiling junction box. It's a heatsink for the LEDs. I ground out a hole using a Dremel cutoff wheel -- that was the best tool I had on hand. And I dropped it while the thermal adhesive was wet. That's why it's smeared all around.
Still, I'm my own worst critic. It's just fine, and I'm sure the recipient will love it.
Tool Magnetizer / Demagnetizer! After all the info yesterday I printed two parts to stick some of those hard drive magnets into and yes, it does work. Both magnetizing & demagnetizing.
I wrapped gaff tape around half of the thing so you have to use the other side because of the polarity of the hard drive magnets.
I should have made the slots a little larger so I could fit two magnets in each cavity.
And now I am tempted to buy one so I can compare performance. 😜
Researchers have discovered that trapping light in specific magnetic materials can greatly amplify their properties, offering potential innovations like magnetic lasers and a fresh perspective on optically controlled magnetic memory. A groundbreaking study conducted by Vinod M. Menon and his team
I made this design so that I can take all of the gadgets and prototyping electronics that I work on and attach it to my laptop making my setup much more portable. I was too late on submitting for the magnet contest, but made an instructables guide on how to set it up. I also have a printables post for the 3D parts. I have mounts...
Q1 Hello Makers! Say hi, and tell us what you’ve been up to this week. #MakersHour
A1: #MakersHour Hello, I’m Alfred and I have been finishing the trusses at @CleavleyWorks, and clearing up a fallen tree branch after Monday’s sudden storm. Also been doing maintenance in Manchester.
