Thank you for making this beautiful kit available and thereby giving me and others the opportunity to play with almost forgotten memory. The assembly was completed in two evenings, the shield worked right away with the supplied sketch. Makes you wonder each time an unsigned long is declared in Arduino.
I enjoyed building this kit so much, I bought a second one so I could do it again (but neater)! It's still amazing to me that it works, and led to me reading about the original inventor of core memory (Jay Forrester) and the computer - the Whirlwind - it was created for. You can see this computer in the Computer History Museum in Mountain View, California.

Thanks for the review John. I am glad you enjoyed the kit.
This DIY core-kit is great. The circuit is well designed and all the components are well to arranged on the print. The whole shield looks very nice. After soldering and loading the Arduino sketch the program works fine. I can read and write to the core's. This shield is a very nice Retro-electronic's learning tool for me.

Thank you for the review. I am glad you appreciate the looks - symmetry is something I aim for when designing PCBs.
The kit and the documentation is excellent. Quality is very good, also good quality power connector and the PCB. The kit is quite easy to assembly and gives a lot of fun and ability to experiment with retro-technology. Also contact with the seller is very good.
This kit was enjoyable to build, and threading cores was easier than I thought it would be. Took three and a half hours to finish. Only trouble I had was enamel coating on wire was troublesome to solder. It is fun to wave a magnet over memory. I would suggest running "t" test to ensure all bits are writing/reading properly.

Thanks for the review Scott. The early kits (2016) used a type of magnet wire that needed to be removed with sandpaper. The newer kits ship with wire that is solderable. I have found out that heating the wire and then scraping it a bit works well.

A great product for the lovers of obsolete electronics
What should I say - a fully working ferrite core memory for Arduino... if you are bored of 64GByte USB-Sticks and multi TByte HDDs, this retro shield is the right thing for you. All parts you need for the smallest USB-Stick available are included in the package and it's a lot of fun to solder your own working core memory... I'm totally satisfied.
By the way, I tried to copy a MP3 to the core memory but failed at writing the file name... 32 bit (4 Byte) is a little bit tight... just kidding...

Thanks for the review and the laughs!
