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.
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.
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...
