Title: GPS Clock Design Survey, Please help a student out.
Post by: varno on August 31, 2014, 05:49:36 am
My designing partner and I are designing a GPS clock for our EE design course and would be very grateful if you would take our survey in order to better focus our design efforts. It can be found  (http://Here) . A preliminary design concept picture can be found below:

I can't fill the survey since it has not choice for under $50 and I don't get good GPS reception in my bedroom.

1. Do you own a digital alarm clock?
Yes, but I only use it to glance at the time. I use my phone for alarms because

2. About how much would you be willing to pay for an ultra accurate clock?
$0. I don't need one. My phone is accurate enough for my purposes—it gets the time from the cell network.

It's a joke?  :-DD

I've made last time sun alarm and since this time I do not set any alarm time-simply when sun rises light detector directed outside window (small garden PV solar panel) turns on NPN transistor gate which trigers triack driving a huge electromagnet which can even hit gongs or other big staff  to wake me up when needed >:D

No time setup needed, but the only thing I want to add is +/- hours potentiometer which will allow me to setup how much time before sun rise or after it should switch on-this requires only cheap RTC clock, while it can learn itself when was sun rise a day ago  8)

If you figure out how to automatically adjust for time zones, let me know. As it turns out, the boundaries between them are not at all regular, and so it is nontrivial task to handle it correctly. There are some online services that handle it, but they cost money and require a connection to the internet.

Hi guys,

I was wondering if anyone who ticked the box saying they would be interested in the oscillator reference would be willing to have a brief chat on IRC about it. I would be most great full

Also thanks guys for being so helpful with my mistake above. I have been bogged down as of late.
