Project updates for Core64 Interactive Core Memory.
SAO Core4 Prototype Demo (V0.1.1)
I've had this project in mind for a while and another Hackaday Contest inspired me to bring a prototype to life. I think a nibble of core memory is going to be surprisingly fun. I look forward to seeing what people will do with this SAO for on the Supercon 2024 badge!

The Core64 Interactive Core Memory kit now has a menu system and improved user interface! I've also added the game of snake which was present in the earliest proof-of-concept that I built. The dGAUSS menu was a convenient result of trying to figure out how to cram a complete menu of options into an 8x8 pixel array. I wanted to encompass all of the functionality that is coming alive in the firmw...

Awesome!
Might just be a winner in both tiny games AND the SAO competition! :D
That'd be a double honor for sure!
Illuminating!
VERY creative.
Brilliant!
You know what would be funny? If this invention caused the downfall of humanity.😂
Really cool -- love this.
Thank you !
I love this! Nice work!
Thank you very much!
Congratulations! That's amazing. I like that you have both the schematic and the actual inside that shows the structure.
Thanks! The schematic and motor structure were two of the most important aspects of the design - great to know that caught your attention!
Truly a clever idea! 🏆That would indeed be a unique "electro-knetic" business card if it had a self contained battery. Thanks for sharing.
Thanks! Making the design more efficient to use a small battery is definitely on my to do list.
Thank you!
Very well done in all aspects and a great learning tool. Now to interface it with CORE-64. :-) The little winder tool is cool. I look forward to seeing it in person.
Thank you for your compliments. Good work noticing the winder!
love it!
Thank you very much!
Super cool, Andy! Great way to learn 🎉
I appreciate your compliments!
Woaw, that's awesome ! It's a very nice piece of work !
Wow thats cool
Thank you! It's another unexpected use of core memory that I wouldn't have figured out if I didn't just start experimenting.
@@andygeppert that's right, curiosity is, of all the human traits, the most important trait in my opinion. If it wasn't for the curiosity we would still wonder if it's the earth that orbits the sun or vice versa
Very interesting work. Thank you for sharing. Looking forward to seeing more... or did this project send you to the funny farm? 😂🖖
Thanks for your compliment. I've paused the weaving fixture by virtue of jamming in other projects... but I intend to get back to this and finish the weaving fixture. Maybe this winter...
I always imagined them being threaded with a sewing needle. Isn't that possible ?
Certainly possible, although connecting/disconnecting the wire from the end of the needle needs to be extremely low profile. I understand that when the companies manufacturing core memories became highly automated, they ran a hollow needle through the matrix, and then a wire inside that. Then they secured the exposed end of the wire and retracted the hollow needle.
mesmerizing
Is it possible to have some sort of magnetic viewer for these cores? Or is the field too weak? It would be cool to have some sort of visualizer besides LEDs being on or off. Maybe an internal oscilloscope of sorts to look at the magnetization curve? This could probably be done with one of the controller's ADCs and sampling the sense amplifier? Then output to a cheap LCD or OLED display. Absolutely brilliant project!
Interesting idea! I've tried to use magnetic paper to visualize the action in the core, but I think the field is extremely weak, and it's fully captured in the loop of the core, so there is nothing left externally to see. Maybe there are other ways? I like the idea of indicating the pulses either on the LED array (would be more suitable for the Core64) or on an optional OLED SAO screen. It would also be helpful for diagnosing failures in the core matrix. I've added it to the TODO list!
….why?
It's a very long lasting, highly resistant, low power form of memory storage
Because he can and is fun? Also this type of RAM may be old design, to big and not able to save much info, but was totally battle tested, literally, was used by the military for ages and was used in space by NASA with high success. Don't take me wrong thou, I'm not saying we should return to it, modern RAM and ROM memory, is way more useful but is good to know other alternatives exist, even if older and their pros and cons.
Watching this makes want to start working with my cores again 🙂
It is better that you are doing this than I because my eyes hurt just watching you weave.
Very clever 🥇
VERY impressive. 👍👍
Man that is a pricey toy.
Really cool idea! 🇬🇧
Thank you!
The leds are something that was suggested to me after doing mine. The person making the suggestion had a knack for making suggestions that would require doing everything again. He’s a narcissist, but it’s nice to see it. The interaction didn’t even enter my head. In my own videos I have destroyed stored data with a magnet to prove things, but I wouldn’t have known the magnet could be reliably and repeatedly flipping core polarity just by being near.
I have since learned that the magnet isn’t really flipping the core. It’s more accurate to say that it is overpowering the matrix wires ability to write to the core, which prevents a sense pulse from occurring. In drawing mode I use that bug as a feature to determine where the magnet is, and then change the LED state. Either way, the net effect was unexpected for me too and turned out to be a lot of fun!
@@andygeppert ok I see. You wouldn’t be able to write a new state to a care with a strong magnet present.
Nice! This came up in my feed.

Fantastic to see these upgrades to an already great kit! I'll do my best to remember to bring you some copies of the issue of IEEE Spectrum in which we reviewed the first kit when I go to VCF East this weekend!
Hey Andy, I think I am going to have to save up my funds for this. The full sized layout has my attention :-D
Great! I'm definitely going to keep offering both the full size and compact version since there is equal demand for both. It will be easier for me to support now that both are using the Pico.
Hello Andy, You did say it would be a long one. Just starting this video and will catch it off and on today 😀
Well that was calming.
We have to push the command's!
Looks nice 👍, go on.
Pretty good solution, I am sure with some minor tweaks this will make it much easier. Nice job!
Awesome! Subscribed,looking forward to more of your works.😊
GREAT technique.👍👍
How many Terabytes does it hold?
As a pair of 32 bit floats, one geo location!
Hi, we met at VCFMW where I punched you 1k of paper tape :). I love the user interface and acronym! I am debating attempting to enlist my wife to help with weaving the core memory I have to admit. Does the LED on/off state and the core memory bit always align, or are they driven seperately?
Thanks for that fun 1K run! Appreciate the feedback on menu. The only mode where state/LED always align is “scrolling text.” I need to revise the drawing mode [firmware] to always reflect it too, as it is constantly scanning the cores looking for a change. The other modes work the same way: write followed by read, expecting to find the opposite state, but if a magnet is present, it blocks the read back as “same state” instead of opposite. It’s subtle, but stems from the fact core reads are destructive. Does that make sense? This is word salad…
Очень интересно
Well done and enjoyed the background music. Just FYI. A radio tech friend suggested to me that when trimming leads, capture the waste piece before cutting to control its movement. A stray waste piece of conductor can sometimes find a way to conduct again.
Love the background music.
Very cool. Can this unit be used as a low res scope?
Certainly. Maybe even a spectrum analyzer too!
That’s really cool.
The game of snake has been expanded to 8x8 bits and is much more playable now: ua-cam.com/video/442IAOkhoIE/v-deo.html
Very well done as it gives consumers a good idea of what they get and what will be required of them in the assembly process. It appears your kit has been very well planned. BTW, TOT would be proud of your presentation.
Thank you! And yes, it is definitely a nod to This Old Tony,
👍
This is quite an achievement. I know the difficulty in reading core memories, obviously you have sorted it out. I have no idea what to use this for. Core memory is still after all these years a bit expensive. I assume all cores had to be woven in by hand. My compliments.
I'm standing on the shoulders of the experts who figured this stuff out long before me. It's been a great learning experience! Yes, these are hand-woven - designed as a kit to be accessible to anyone who wants the experience of bringing them to live. Thanks for the compliments.
hey, i was just wandering. wat will happen you reverse this system. can you make magnetic images with it ? if you use a magnetic flux indicator strip.
I think that would be possible, but it would take larger cores, or electromagnets with a primary magnetic flux axis exposed. These cores are relatively easy to saturate, and the magnetic field is essentially fully contained in the core itself.
oh i got it. its like a touchscreen for magnets. incredible work ! hope to see more updates on it in the future !
