About The Project

Starting into home roasting I've quickly realised the importance of a roast meter to evaluate the color of the coffee, this helps you better target different end temperature/time but retain the same level of color and see how it influences taste.

Here's why:

• Commercial grade roast meters are very expensive
• Chips and sensors are are readily available/cheap and easy to get going
• At the end of the guide you will have an ~100$ roast meter, that is consistent and can help you get the most out of your roast.

Check out our wiki for detailed instructions for assembly usage and calibration!
