A new video on #PostMarketOS #Linux with #Gnome Mobile #performance #benchmark for the #TierList youtube.com/watch?v=o7oovDNoyx. The best performing Gnome distribution tested so far. However, it appears that there are better options for an #OpenSource #DesktopEnvironment. Curious what options people go with. Note there will be a video soon about #ControlSystems. <3

So, on my last DC-DC converter, I left off messing around with the control loop. I got it working decently, but there were still some oscillations. Thinking about it, this was probably due to ADC resolution, which is 10 bits on that microcontroller, while the PWM register I was using is 8 bits.

If you think about it (which I didn't initially), that means that you get quantization error, since the ADC can read voltages and currents the PWM (via the MOSFETs and the rest of the converter) won't produce. In other words, the controller is demanding more than what the converter can do.

I think I can maybe add some extra filtering to fix that. In the future, I'll try using the 16 bit register for PWM as well.

#Insights into #gene & #protein #ControlSystems that regulate the use of #nitrogen by #plant #roots could help develop crops that require less nitrogenous fertilizers to produce acceptable yields. Plant #biochemist Soichi Kojima and colleagues at #TohokuUniversity discuss their findings and future plans in an article in the journal #Frontiers in #PlantScience.

ScienceDailyRooting out how plants control nitrogen useNitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off into lakes and rivers causes serious ecological imbalances. A recent study has uncovered the regulatory mechanisms at work when plants utilize nitrogenous fertilizers in their roots, a positive step in the quest to generate crops that require less fertilizer while still producing the yields needed to feed the world.
