HHAMS Field Calendar for Smartphones

Field Calendar as app icon on iPhone home screenIn my time between two jobs, I wrote a calendar app for HHAMS (Hempstead Harbor Aero Modelers Society). Or, at least, members see it as an “app”, since  the calendar runs on smartphones, and can be set up as an icon on the home screen. It is really just a webpage served up by a Flask server.

The calendar allows safety officers and members alike to organize field activities as they unfold today, or to plan activities ahead of time. It works on all smart phones as well as desktop PCs. Information on the calendar is only visible to HHAMS members registered in the system. And only members can create entries on the calendar.

The calendar complements two existing communication systems in use: the Yahoo Groups mailing list for monthly newsletter and official communications, plus the field texting service used by safety officers to broadcast field open/close notifications.

If the field texting service were free, and members were extremely tolerant of daily text spams to the whole club inquiring and making plans to meet at the field and to keep it open, we would have no need for an online Field Calendar. But field texting is expensive, and people in general hate spams… except when they are the ones sending these spams.

Thus the Field Calendar.

The main calendar page shows, at the top, official field open/close notifications posted by the Safety Officer In Charge (SOC) at the field. The rest of the page show flying hours and tentative entries created by members.

Update 2016-10-06. The calendar learned a new trick. It now shows current weather conditions including wind speed and direction. It also show hourly forecast of wind condition and chance of precipitation for the next ten days on the calendar.

Fly responsibly. And try not to make garbage.

About Xinhai Dude 辛亥生

The name Xinhai Dude 辛亥生 is a pun in Chinese, as it means both “he who was born in Xinhai” as well as “he who studies Xinhai”. I had an ambitious plan to write something about the great Xinhai Revolution of 1911, thus my blog https://xinhaidude.com. But after an initial flurry of activities the initiative petered out. One day I will still carry it through. But for now, this website has turned into a conglomerate of my work on various topics of interest to me, including travel pictures, RC model airplane flying, inline skating, ice skating, classical music composition, science fiction short stories, evolution and atheism.
