Re: Port 123 blocked, how to set time?

Contact the network admin and request that the block on that port be removed. The worst that will happen is that the admin says, "No."

Re: finding older model RPi on the used market

I find it odd that someone would balk at paying $35 for a Pi2B, Pi3B, or Pi3B+, or even $20 for an A+ when the original kickstarter for Raspberry Shake was over $100, and the Raspberry Boom is more like $200. If you can afford the Raspberry Shake, the Pi to go with it shouldn't be an issue.

Re: project

Welcome to the forums.

From your question, I must presume the Google is down today. (Or to put it a bit more obviously..if you search the web for "Pi camera motion detector" you will get 291,000 hits and the first two are specifically on using a Pi camera to build a motion detector.)

Re: Completely new

The best way to start is to get the current top of the line board. At the time of writing, that is the Pi3B+. To go with it, you need the following things (some of which you may already have): microSD card, at least 8GB. Having more than one is handy. PSU. Use the official RPF one, 5.1v, 2.5A (Pi3B+...

That still doesn't explain why you think you need to capture at 40 fps.

Re: Help me to benchmark Raspberry Pi 3 Model B+

Since this appears to be a commercial effort, you really should buy your own board to test. If you don't want to keep it afterwards, you can donate to some person or organization. What you're asking for is people's *time*, and that is worth considerably more than the cost of the Pi3B+.

That's a Rev. 2.0 Model B, *not* a Pi2B. The 512MB also gives it away as all versions of the Pi2B have 1GB. ...

Now if I can USBboot the Pi3A+ too like I do with Zero's I can develop code and save SD card wear.
5GHz WiFi and 2.4Ghz BT is good spectrum separation, if they can be used at the same time?
