I decided not to be lazy with this EEPROM library. Other libraries I've tossed in delays of 1 uS to ensure communication timing wasn't too fast

This time I wrote a startup function to calculate one cpu tick in nS, then built a delayNano function

Before this, it would've taken about 64 uS to read one byte...

Now it'll take 6.4 uS

In the blink of an eye that's nothing, but for finer measurements it's everything

"Bifacial perovskite solar cells, which capture sunlight from both sides, have shown great potential for enhancing solar energy efficiency. Researchers at the Indian Institute of Technology (IIT) have recently advanced their development by introducing a novel NiO/Ag/NiO (NAN) transparent electrode. This innovation improves efficiency, durability, and infrared transparency, offering promising applications in solar energy technology.

"As detailed in the Journal of Photonics for Energy, a research team from IIT Dharwad designed and fabricated bifacial solar cells with high infrared transparency. They achieved this by integrating a hybrid top transparent electrode (TE) composed of a three-layer NiO/Ag/NiO structure. Using a low-energy physical vapor deposition technique, they developed an electrode with exceptionally low electrical resistance and high visible light transmittance, significantly enhancing the performance of these solar cells."

I'm not a laundry expert so I'm just going to throw this question out there: how is tying all my clothes into a daisy chain of tight knots highly efficient?

Based on the CO2 decay in our ~380sqft (~35m^2) utility building, I've calculated it has a natural ACH (not ACH50) of ~0.07.

Considering the building is still under construction, and the insulation + interior air barrier (walls and ceiling) isn't yet installed, I'm very happy with this.

Our goal is to make it as airtight as possible and then ventilation will be actively managed with a Lunos e2 HRV.

First insulation boards being installed. This is the first of two, 2” thick layers we’ll have.
