Lotus search Lotus search is a tool to search for compounds and taxa in the Lotus database. What is LOTUS? The LOTUS database is a database of natural products, their associated producing organisms and the bibliographical references in which the discovery or identification was made. It is hosted on Wikidata as the main source of truth. It is the result of a pretty large collaboration within the LOTUS initiative. How was the search made?

DINOctopus What is it DINOctopus is a small device made to merge/split/mix MIDI signals and act as a USB card as well. Current status I use it every day as my midi merger, and it has been working great so far. It requires some love on the software and hardware side, so that’s not production ready yet. Interface The settings can be seen and modified on the integrated display using the integrated rotary encoder:

On using 3d printer screens and controllers for your own projects.

I bought some of those cheap 3d printer controllers on the big evil site for $12: BigTreeTech Mini 12864. There are other similar ones in the same price range from other brands, but I can’t guarantee they have the same pinouts and controllers. Also these came with a tiny yellow rubber duck, always useful when you try to make sense of schematics.

The thing is, these are made for 3d printers so they expect you to plug them directly and not worry about implementation details.

Fun thing is, for some printer models, you need to make an adapter cable as nobody seemed to have settled on a standard for those and pinouts are all over the place.

To save you from the hassle of figuring out how to use those with an Arduino or an ESP, and likely for me later when I will need that again, I decided to write down all I discovered about them.
