Re: Pi 3 Model B Wifi Range

Not entirely sure what you are asking tbh, are you wanting to use it as a range extender? Or just as a standalone Wi-Fi AP? You are not going to get very good range with the onboard Wi-Fi, you will need an external Wi-Fi card and antenna to get 300 yards. For example this: http://www.ebay.co.uk/itm/...

Re: Raspberry Pi as a motor controller and counter

This is a good video showing how someone else has done something similar.

Re: Slaving motors to spindle speed

You would be better using an arduino for this kind of task, outputting accurate pulses to drive the stepper motors would be a nightmare on the pi. If you are looking for a nice board that can do this then the pokeys ones are good and include a pulse engine for driving stepper motors. https://www.pos...

Re: Unmanned Ground Vehicle - Tiberius

Over the last 8 months I have been working on Tiberius III, the third incarnation of Heriot-Watt's autonomous ground vehicle. The whole robot has been redesigned from the ground up with new frame, motors, fully independent suspension and active steering, lots of new sensors and a new 3d printed arm ...

Re: Sonos replacement

I didn't have any 4GB sd cards, only a 1GB so it wouldn't fit. Also PiCorePlayer is read only so it doesn't trash the sd card. Also the squeezeplug pi image is out of date and doesn't work on the latest model b. I didn't have much time and couldn't be bother to install raspbian then run the conversi...

Re: Sonos replacement

I bought bare speaker drivers from maplin (yes I know they are probably crap) and power them using a Muse M20 EX2 Class T amplifier. The Pi, amp and speakers are all in a custom built wooden case. I also found that squeezebox lets you pick which audio channels to output on the player settings page. ...

Re: Sonos replacement

Just connect the 3.5mm jack on your amp to the pi, you could add a switch to pick which audio channels come out of the speakers if you wanted to have one on each side of room in order to get stereo. You always need an amplifier with it and you want to set the volume on the pi very low and use the am...
