About Heys Scientific

Heys Scientific is a family project rooted in engineering precision and a love for coffee. Co-founder Lloyd Pennington grew up with a father who treated design as both science and art. That obsession with detail now meets the passion of his son, Oliver, a specialty coffee enthusiast.

Together they created the Mikros One, a hand grinder built for people who love to experiment. With single-micron adjustments, swappable burrs, and a Vernier scale, it offers control and repeatability that home grinders usually lack.

Durability matters as much as performance. The Mikros One is designed to last, with a focus on serviceable parts and a commitment to the Right to Repair — because the best tools should stay with you for years, not seasons

About Us

A brief history of [our] time…

Becoming

Lloyd begins to learn about engineering from his precision obsessed father Ronnie, in the home workshop at 39 The Heys, Coppull, and a lifelong passion ignites.

An idea brews

Lloyd’s son Oliver has his inherited the family obsession with precision, but this time it’s with specialty coffee. Oliver dreams up the idea of a super precise grinder.

The prototypes

Lloyd gets working on the idea in Computer Aided Design. Prototypes are built and are shown to the public at the Manchester Coffee Festival and valuable feedback is sought.

Iteration

Another year of hard work begins. Lloyd quits his job, designing scientific instruments to go all in on the Mikros One precision hand grinder. A new prototype is made, an evolution from lessons learned and eight new improvements.

A set back

Manufacturing begins, but the U.K. suppler fails to deliver parts to the required standard after more than a year of patiently waiting. Heys Scientific almost runs out of money as a result.

The launch

No time is wasted during the year long wait. Lloyd and Oliver add to the range of grinders, seeking to make their discoveries and innovation available to a broader audience.
After regrouping, Lloyds old friend and chartered financial analyst Rob joins the team to provide a much needed guiding hand.
