Just a wild stab at it but this might work: <a href="http://www.amazon.com/WIMM-One-Wearable-Android-Device/dp/B0056BIYQA/ref=pd_sbs_watch_2">http://www.amazon.com/WIMM-One-Wearable-Android-Device/dp/B0056BIYQA/ref=pd_sbs_watch_2</a> <div class="gmail_quote">On Tue, Jun 19, 2012 at 7:02 AM, David Cabot <<a href="mailto:dave.cabot@ossengineering.com" target="_blank">dave.cabot@ossengineering.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> My apologies that this isn't a ubuntu Q. I need some ideas though. I've got a child with Downs and he thinks it's funny to escape the house. I've had strangers find him on the road. I've taken preventative measures, but he's too smart. A real Houdini. Yes, there are products out there, but they're expensive and subscription based. What I'm thinking is this. I need a device, about the size of a watch, that's wifi enabled. I can embed an app on it that will send a ping to a device on my local network. That device, most likely will look like a linksys router with a speaker and a button. If the receiver looses the signal for any amount of time, then an alarm will go off. The button is for indicating that we're leaving the house and not to monitor until the child gets back into range. It's the "watch" that I need help with. I know that there are SD cards that are wifi enabled. Has anyone since something like a watch that's wifi enabled?
