It seems that my 16-year-old Satellite AS-878 sound is not working so well anymore... the guys who used to repair it, they do not repair it anymore... a new sound system for my computer would be extremely expensive, so I am simply using my JBL Go 4 for now. I think about Edifier X100B RMS 15W
like this. Also, my headphone piece collapsed, and I stopped using it because it is now hurting my head. Apparently, no warranty.
I tried to scan a book with Google Drive. It seems to be interesting; however, it requires a lot of attention and physical effort from my fingers. Is there anything better than that? That's even though I'm still using my phone with a tripod, saving my arms some of the strain.

It seems that Ágatha did not like the model I tried to draw. Indeed, the real model is far more beautiful than this simple drawing.
For my brine shrimp culture, it seems that the only solution to remove detritus from the water without losing brine shrimp with a siphon is to rake on the substrate, so all of the settled organic matter is suspended, and then my sponge filter catches all of that (I increase abruptly the air pump flow rate to the maximum), while the shrimp may eat some of these suspended particles. Later, I wash this sponge filter with water, and then I place it on the culture again.
