Re: Reconnecting bluetooh keyboard and mouse at startup

i was able to get the keyboard to reconnect across reboots, however the mouse would not - in fact, I lost the ability to use the mouse, period - no joy trying to reconnect NOR re-pair-then-connect. The keyboard, too, goes to sleep after a period of inactivity and doesn't come back - and, of course, ...

Re: SOLVED: Bluetooth Keyboard Help Needed

Unfortunately, the link in the 2nd post to the "guide" isn't entirely working for me - I was able to get a bluetooth keyboard enabled and to stay enabled across shutdowns and reboots, however a bluetooth mouse (Microsoft) is simply not coming up correctly though I have been able to get its presence ...

Re: Reconnecting bluetooh keyboard and mouse at startup

My ultimate goal is to de-attach wired-keyboard and wired-mouse and simply use bluetooth same as my primary input devices. It's not clear at all how one goes about doing this - I was able to manually get all four devices working at the same time but, so far, am not getting any sort of persistence ac...

Re: Hangup during boot sequence

First, the output is off-center so the first couple of letters of each line are not visible (we have a new 'Vizio' hdmi screen).

Re: Copying 4GB card to 16GB card

It shouldn't do it automatically because that might not be what you want (that is to say, it WON'T do it automatically).

Re: OK, Careful what you wish for

I would think a programmatic fix would be the easiest - all the IR filter does is remove information, thus enhancing other information. That probably could be done with software as well.

Re: How to run a solenoid?

One of the GPIO (General Purpose I/O) pins of the Pi can be used to "send an extend signal" to the solenoid circuitry. That signal probably can't be used by itself because of current requirements of the solenoid and other interesting things that happen when the signal is turned off and the solenoid ...

Re: Advice on humanoid

The Raspberry Pi is a 700Mhz ARM processor with a GPU and quite a bit of memory with the ability to have electronic outputs and/or inputs from external "devices" - for most output purposes you for sure would need some buffering. Given that, what you need to do is (1) decide what your Asimo-clone is ...

The ground affects this: https://en.wikipedia.org/wiki/Fresnel_zone
While that's interesting I wonder how much attenuation actually occurs due to ground effect and whether it's actually important for this case.

I would expect standard Wifi to work at normal kite altitudes with the default antenna. There's nothing in the way to attenuate the signal to the ground. I'd bet wifi dongles are minimal range in the wifi scheme of things. In any case, a simple test would be to place the router at a location and wa...

Use one of the many antenna designs for Wifi enhancement that are available on the 'Net - some can significantly increase range with minimal weight - the router, too, can have an enhanced antenna - you might have to actively manage the aiming of the router antenna as you're flying your kite.

How the Pi could directly help your main computer, I don't know.

The taking, preprocessing and sending can, of course, be done in pseud...
