I like using a Soroban for calculations and wanted to have one with me when I go shopping. So I needed a small model that would allow me to maintain the configuration while walking.

Simply press the button to release the moving parts and perform your calculations; once the button is released, the beads stay in position.

It uses simple pen springs (in the outer holes of the board). Spacers are provided to adjust the spring tension if needed.

This Soroban is inspired by the Pocket abacus with cover by Maker Maxwell .
