Mother of the Sea

Happy birthday Kathleen Mary Drew-Baker

I named one of my modular keyboards "nori". I did some googling and found a fascinating story. The modern Japanese nori industry venerates a British scientist for her discovery about the life cycle of a specific algae. The Japanese applied this knowledge to greatly improve the farming of algae that becomes nori.

Having eaten nori in some form or another most of my life, this story surprised me.

If you are in the UK, the BBC broadcast a program about the relationship the Japanese have with her.

Ars Technica published an article about "How an unpaid UK researcher saved the Japanese seaweed industry".

Cheap Green Arduino Micro and Pro Micro clones

Back in stock on Aliexpress

I bought these before but they stopped showing up on Aliexpress. Both are now back in stock.

The Pro Micro clone is not an exact copy of the Sparkfun Pro Micro. It will not work properly in many split keyboards.

The green Arduino Micro clone is also different than the genuine Arduino Micro. In many ways it is better since it is thinner and has components only on the top side. It also has a Micro USB connector instead of Mini USB.

You can find the green Pro Micro by searching for BTE17-05.

The green Arduino Micro clone is listed under CNT-013.

They do not come with any headers. Just the board by itself.

I bought several.
