• Better Raspberry Pi Pico MIDI controller

    thumbnail for Better Raspberry Pi Pico MIDI controller

    To expand the number of notes/chords my RP2040 based MIDI controller can play we’ll turn two keys into modifiers. This way the other 7 buttons can actually each be assigned 4 different notes/chords (a default, pressed with modifier one, pressed with modifier two and pressed with both modifiers active). So...

    In a previous post about clustering the palmer penguins using PyMC3, the mixture model was implemented in the model itself. Though this is great for understanding what is going on, it isn’t very efficient when sampling the model. Furthermore, observations (here penguins) were assigned to groups (here the species of...

Fantasy Flight Games never released data on how many decks were printed per run. Though with Dark Tiding having Evil Twin decks (exact...

    Imagine you wish to know how many fish are in a rather large pond… The water is murky so forget about counting them easily… In ecology this is a common problem! The population size of a species often needs to be known, but it is either impractical or simply impossible...

    All our lives were impacted by COVID-19, but what was the impact on KeyForge sales? There was a very technical post last month, this one is intended for everyone that cares about KeyForge, but not the details of how to create models. 500 000 fewer decks registered during COVID This...
