That's a nice idea. I wish stuff like this was builtin. Small suggestion: API level 29 (Android 10) introduced WifiNetworkSuggestion[1], which allows an app to prompt the user to add WiFi credentials to the system. The suggestion has to be sent as an extra in an ACTION_WIFI_ADD_NETWORKS intent[2] (which was added in API 30 for some reason, not sure right now what happens in between).
Thanks for the suggestion! I initially went with that approach [1], but eventually opted for on-screen QR code scanning. Suggested networks have lower connection priority and don’t always auto-connect. Also, passwords for suggested networks can’t be viewed or shared later, unlike regular WiFi connections. This is inconvenient because I often need to connect my Mac to the same network later.
You usually mount mirrors vertically so dust does not settle on them that much (also it is safer to keep laser light propagating horizontally at only one height). Additionally, overhead ventilation is often installed which provides a vertical Laminar flow of dust-free air. If you have to clean the mirrors eventually, you'd use compressed (clean) air or special mirror cleaning wipes. Thorlabs (lab supply company) has a detailed guide on optics cleaning[1]
