#43705 Advice on measuring the time delta among pulses on as many as 6 inputs

Posted by emg on 18 January 2013 - 11:22 PM in General Discussion

If you are trying to locate by using TDOA (time difference of arrival), would the sensors not need to be a few feet apart to get a measurable time difference? How far are the sensors apart?

What about sensing peak intensity or how 'loud' the chirp is to derive a general directional bearing? So you would poll their last reading and adjust heading so the front sensor has the highest reading? You could then use an ultrasonic rangefinder to provide a distance measurement and collision avoidance.

#42342 Visual Basic support for Netduino and .NET MF now in beta

Posted by emg on 28 December 2012 - 11:36 AM in Visual Basic Support

I must have missed this too, does VB now implement System.Convert.ToUInt64, Decimal, etc? (try decoding a NTP time byte string in VB only!)

I am plucking up the courage to do the firmware re-install.

On mine there is a button for 'Factory data reset' under Settings|Personal. I've done this already after messing about and it works well. Right back to square one.

HI Steve,

I used to use Chrome and it worked fairly well, until about a month or so ago when there was an update. Now I get "Unfortunately, Chrome has stopped" when ever I try and start it. Even after a factory reset and re-install!

I just tried Dolphin (recomended by a friend), that does the same as the default browser - half the page disapears when I try and add text to the reply box.

Given the others on this forum who have responded that their browser's are working, I think it must be this tablet that is at fault. I'll have to add "SUMVISION" to the home electronics black list.

Thanks everyone - keep unwrapping those presents.

Have you tried resetting the tablet back to defaults? What about the latest firmware updates like these:

I purchased this for �65 last week:

http://www.ergoelect...tablet-gbt740rs

and it seems OK. I have noticed that it struggles with big websites and can sometimes pause for a few seconds before updating. I plan on using it to control some home automation tasks so it should be sufficient.

Good luck!

Sorry, don't know the specifics of the issue(s) but your description seems to match others trouble-shooting attempts and results. I have a brand new N+2 still sitting in the box waiting for the firmware update that was due out last weekend. This is supposed to resolve this and SPI issues. Here's hoping... I would wait for the next firmware before changing any of your code and/or other devices.

I think there are still unresolved issues with 4.2 ethernet on N+2, see other threads about MAC address and fixed IP/DHCP problems...

Have you thought about using the nylon PCB stand off type mounts?

I've used these: Mini Locking Circuit Board Support
They have a self adhesive base and work well for me...
