• Pioreactor development log #4

    🌊 This week we investigated some sampling tricks to improve our ADCs, and managed to get a 50% reduction in signal variance, and gain many more bit...
  • Pioreactor development log #3

    🔑 This week we explored key-value databases for storing data, and implemented a solution that is designed to get wiped often. At the end of the day...
  • Pioreactor development log #2

    ⭐️ This week, we added some updates to the user-interface, a new data-viz, and did our first tests comparing heated and non-heated effects on grow...
  • Pioreactor development log #1

    💡 Going forward, we'll try to write weekly blog posts with details about interesting additions, challenges, and ideas we have while building the P...
  • How we built a bioreactor on top of the Raspberry Pi

    The Raspberry Pi is a low-cost, single-board computer that has exploded in both at-home use and in industry. What makes the Raspberry Pi so usef...
  • Adding a bubbler to your Pioreactor

    An important growth requirement for aerobic microorganisms, which include all yeast, algae, and some bacteria, is an abundance of oxygen (or CO₂ in...
  • Replication, variance, (and growth rates) in Pioreactors

    One important property we wanted Pioreactors to have was low variance between units. That is, one Pioreactor should be interchangeable with another...
  • Don't be fooled: Yeast have two growth spurts!

    Did you know that the traditional S-shaped growth curve in microbiology is terribly inaccurate? It's inaccurate for many reasons, but the reason I ...
  • Measuring the effects of a nutrient mix on yeast growth

    My goal was to compare two yeast cultures in Pioreactors: one with generous amounts of Yeast Lightning (labelled the YL culture), and one with no added Yeast Lightning (No-YL culture). The media was 2% dextrose, with moderate amounts of DAP and hydrolyzed soy as nitrogen sources.
