1. How hard would it be to make this more user-friendly?
2. Is it possible to make an offline version of this and have a 10 year Jewish Calendar installed on the device?
3. Would you consider selling preconfigured devices at Judaica Stores?
4. If yes, can I partner?
1. I'm using open source software, so no real changes there
2. Definitely, the calculations on there should be able to last forever. There is no commercial smart plug with a RTC on it so that will have to be custom made. (RTC is a real time clock that keeps track of the time)
3/4 I don't think that many people would be interested in a single purpose plug. But I thought about it too.
In short the greatest part of it is the open source software and the customization it allows.
