Single Basket Espresso Made Easy: A 3D Printed Solution

As a coffee lover, you often found yourself craving the rich, bold flavour of espresso. However, brewing a single shot of espresso could be a real challenge – the small size of the basket makes it difficult to get the right amount of coffee in without making a mess, and using a regular tamper is nearly impossible. I saw some single dosing funnels online, but …

ChatGPT is a artificial intelligence chatbot created by OpenAI. This clever bot was launched in November 2022. People are amazed at how detailed and articulate ChatGPT’s responses are, even though some people say it’s not always 100% accurate.

3D printed Compak hopper adapter for Mahlkonig K30 grinder

I recently bought a second hand Mahlkonig K30 Vario grinder. This grinder did not work at all but I got it for only 150 euro.

This made me happy but the grinder was …

TC4 board by Viliam

More than 12% of this coffee should not land in your cup of joe. But after proper sorting, this bean can really shine. The problem however is that this sorting is a tedious proces. …
