Many Eureka Mignon owners run into a frustrating timer bug:
- Lowering the time with
-works fine. - Increasing the time with
+is blocked by the display.
To fix this, I offer a flash/patch service for the display of the Eureka Mignon Specialità grinder. Read more about the issue in my blog post.

For €30,- per board I will flash your display for you, so you don’t have to deal with a programmer yourself. If you send multiple boards, we can set-up a discount, just contact me and we’ll figure out what’s possible.
How it works: you ship the board to me, I take care of the flashing/patching/testing, and you get your board back in approximately 1 week.
Please describe your specific issue to me so that I can check if it matches the symptoms of the bug.
Questions or ready to order? Contact me via e-mail at hello@itty.nl or reach out on LinkedIn.
The patch itself is open source, available here: eureka-pic16f1936-patch
