Linobyte - Winding toroids and fixing them to a 3D printed support.
The coils are one of the most important aspects of Linobyte. In this video I wind some enamelled copper wire around a ferrite toroid. The toroid is then glued onto a 3D printed part, which then has some M2 threads cut on it. Each Linobyte uses 64 coils (8 * 8 bytes).

Linobyte - Paste, populate, reflow. Assembling the "Char" boards.
Переглядів 1,3 тис.5 років тому
Linobyte is a core rope ROM device. This video shows the assembly of the "Char" (character) boards. The first step is the application of solder paste with the framed stencil onto the PCBs. The second step is placing the SMD components on the board using the vacuum tweezer (a manual pick and place process). The third step is reflowing the PCBA on the prototype oven to get the parts soldered. Che...
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 ...
Brilliant!
You can use spot welding to bond the wire without damaging the magnet
The idea to use higher iron temp to let the solder instantly melt to the magnet is amazing
i would suggest thick short pogo pins for contating and magnets for interlocking
agreed! Pogos are the best choice, I just wanted to try something new :)
You are press fitting and glueing. You could have had a "spring contact"
It doesn't heat the whole magnet but the heat transfer just kills the area where it touched, by that time tin bonds
Please make a dildo with magnets.
The use of a knife tip is ridiculous.
gotta keep things interesting
(the knife tip is the one I leave on both my stations as standard)
inspiring. not just for conducing electricity .
But why tho?
please continue
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.
"Perfectionist"... "oposit". Yeah, that seems legit.
Try a wirebonding, welding technique, the magnet wont heat up as much Edit: Or ultrasonic soldering
ultrasonic will require a substrate that can alloy with the wire. There's typically a very thin coat of nickel that I don't think would be mechanically strong enough. It wouldn't be outrageous to consider conductive adhesive here... or to re-magnetize the magnets after soldering.
@@stickyfox ive seen a video about soldering to glass with normal solder, that cant form an alloy with glass
Why not spot weld?
I don't have a spot welder :)
@@WesleyLeeYang no worries. Cool project, it looks like you’re making core memory? From your other vids i mean
@@weirdsciencetv4999 yes it was a core ROM which you could "rewrite" by unplugging the magnetic connector and rewinding it. Here some pics of it: instagram.com/p/Bp-DHSkncB6
It's a tissue-thin layer of nickel over ceramic and probably won't take a weld.
@@stickyfox spot welds are a bit different than typical weld, especially with the kinds used for making battery packs
What type of vice is that ?
Its a toolmaker/machinists vice.
Hello wesley lee, I am intrested in a rassberry pi project I'd like to collab on with you. Utilizing this exzact idea.
Hey Erik! Send me an email (wesley6@gmail.com) or dm me at instagram: @wes_ee, lets see what we can do
This is beautiful :')
A little too advanced for me. DISLIKED.
mybluebelly this wasn’t a how to but.. ok
@@WesleyLeeYang You failed to show us the bigger picture. Leaves me wondering what the hell this is. Unless the viewer has intimate knowledge about these things, we need to be enlightened.
@@mybluebelly If you want more info it is published here: wes.am/linobyte/ and I think all the files and code is on Github. UA-cam wasn't the primary place where I published this hence the information is incomplete in this platform. There were longer format videos as well that where shown in exhibitions along with the device so in other contexts it would be clearer what this is. Added to that, considering that this was a personal project, there aren't many people besides me or the collectors of the device that have intimate knowledge on it. Either way, I chose to publish the videos because I thought it was worth sharing but unfortunately, yes, they do lack on info.
@@mybluebelly p.s.: I try my best to answer questions related to the project or techniques depicted but.. if I don't know what you want to know unfortunately I can't try to help.
There are plenty of LOLcat videos elsewhere that you can watch.
After soldering the wire to the magnets they turned into scrap metal. The magnetism is completely gone.. wtf?
Magnets lose their properties with heat (Curie temp). So you have to be fast (not allow the whole magnet to reach that temperature). In my case, I was also soldering the magnets on a steel vise, so it acted a bit as a heatsink as well.
They are like that brand new too. They don't become magnets until they're magnetized.
Pls make a USB connection with magnets
Great job no thumbs down so far. THE LORD GOD ALMIGHTY YESHUA THE CHRIST bless you
bro what camera and lense are you using?
this was shot on a Nikon D600, using Rokinon 85mm 1.4 and Nikon 24-70mm 2.8, both with macro adapters where necessary
hey bro i love your work, can you make convert a regual android charger to magnetically connectable charger?
I think you can buy "magsafe" micro-usb adapters
why is this so satisfying?
Very cool!
Glad you enjoy it! :)
Doesn't the magnet heat up enough to reach curie temperature and lose magnetism? AFAIK neodymium magnets have a pretty low curie temperature.
screw probably acts as a good heatsink. And he solders pretty dang fast :)
As Rik said, the screw (and the vise) act as a heatsink, and speed helps a lot. The magnet does lose a bit of the magnetivity though. That said, the initial plan was to have the magnet on the wire non-magnetic, and the one on the back of the PCB would attract it. However that turned out to be a bit weak.
@@WesleyLeeYang Thanks for the answer! This looks like a beautiful concept, I love magnets locking :) it's so satisfying. I'll have to buy some little disks :P
+Gabriel Rodríguez Gutiérrez The magnets clicking are indeed very satisfactory! More satisfactory than reliable I'd bet! lol
If the gold wears down, you could consider carbon coating the connections, but I'm not sure it will be necessary
Phenomenal
Thanks! Glad you enjoyed it!
