Linobyte - Soldering wire to neodymium magnets and embedding them into a 3D print

Linobyte is a core rope ROM device.

This video depicts the fabrication of a magnetic switch / connector. When it is plugged, it serves as a connection of the wire to ground. It also pulls another signal on the board to 0V, enabling other parts of the circuitry.

I'm not sure how long the connector will be good for, as the pulling force is relatively weak. The magnet and PCBs are gold plated, so I hope it should last for a while.

It doesn't heat the whole magnet but the heat transfer just kills the area where it touched, by that time tin bonds

[rojirrim]

Doesn't the magnet heat up enough to reach curie temperature and lose magnetism? AFAIK neodymium magnets have a pretty low curie temperature.

[indian.techsupport]

Try a wirebonding, welding technique, the magnet wont heat up as much

Edit: Or ultrasonic soldering

[GhVost]

i would suggest thick short pogo pins for contating and magnets for interlocking

[a.c.]

You can use spot welding to bond the wire without damaging the magnet

[HappySlappyFace]

The idea to use higher iron temp to let the solder instantly melt to the magnet is amazing

[its_grpes]

Id love to know what type of prep the magnet underwent before soldering, I'm currently trying to use technology in an engineering project and I have a feeling that soldering magnets will be our bottleneck.

You are press fitting and glueing.
You could have had a "spring contact"

[sufyaankhan]

Could glue be used to glue it to the magnet?

[badhonebrahim]

Pls make a USB connection with magnets

[leornere]

What is the metal part you put the magnet in called?

[eniggma]

inspiring. not just for conducing electricity .

[badhonebrahim]

hey bro i love your work, can you make convert a regual android charger to magnetically connectable charger?

0:34 I reaaly need to stop being perfectionnist (it's really not a good trait, quite the oposit), I would never be able to film and post this was I thinking to myself, but is the point of the video met ? Yes and that's all what counts, no need for the print or the fit to be perfect. Thank you for showing this really awesome idea Man.

[RobertSmith-uemn]

Great job no thumbs down so far. THE LORD GOD ALMIGHTY YESHUA THE CHRIST bless you

Hello wesley lee, I am intrested in a rassberry pi project I'd like to collab on with you. Utilizing this exzact idea.

[AnimilesYT]

After soldering the wire to the magnets they turned into scrap metal. The magnetism is completely gone.. wtf?

[mybluebelly]

A little too advanced for me. DISLIKED.
