Baratza improvements

Introduction

The Baratza Encore is probably the best no-frills coffee grinder out there.

It lacks a few things though:

• It doesn’t have a timer, so you need to time the grind yourself if you want to grind only the amount for one coffee.
• It has a container for the ground coffee, but I’d rather have a porta-filter fitting so I don’t need to use the container.

Let’s solve those issues:

Porta-filter adapter

I’ve found a design online which was exactly what I was looking for, so I just made small adjustments and printed it. Easy.

Built with:

• Autodesk Fusion
• HAKKO FX-888D Soldering Iron
• X1C/P2S 3D Printer

Timer

To create the timer, I’ve embedded an Arduino Leonardo which I had laying around (I know it’s overkill and I’ll replace it with an ATMega custom board soon) which I’ve powered through a USB power adapter stripped down.

The Arduino was programmed to keep a timer stored in the ROM. The timer is set by holding the push button on the Baratza (the one for the pulse grind which I disconnected).

When the button is short-pressed, the grinder is turned on for the period previously set. Perfect amount of coffee every time.
