Pi Docking Station/Cluster

Intro: Hi all, I'm starting a new project with some RPi's I have laying around. My end result goal is to create basically a "station" where I can dock all of my Pi's (varying models) in one place to give them internet access, power, and port accessibility (mostly HDMI for debugging) for future use....

Re: Cwiid wiimote range

The Pi is not going to know whether you are out of range, or just not pressing any buttons. You would need to continuously scan for the wiimote, and perform an action if the received signal strength is less than a given value. Not trivial. The Wii remote still reports the state of the controller wh...

Pi B+ micro SD to Pi 2?

Hello, I have a RPi B+ running Raspbian with some extra python modules and some other drivers on it, and I was wondering if I can put that mSD card into a RPi 2 so I can have all of my stuff still on it. I know you can with same model Pi's (B+ to B+), but since the Pi 2 has physically different hard...

Cwiid wiimote range

Hi all, I have been working on a python script that I use to control a robot, and I have noticed that the range of my bluetooth connection is not that great. Whenever I do get out of range, my robot continues to do what the python program ran last. If I blast the throttle and it goes out of range, t...

Hi guys, I am trying to make a robot controlled by tilting a wii remote! Kinda new to python and coding in general, so structure of the code might not be very efficient, but contstructive criticism is welcome. This is just a small chunk of my code, but basically I'm assigning a variable with a stati...

Re: Control PWM frequencies with RPi.GPIO

Ok, thank you. I am starting to get some responses from my motor controller now. Right and left correspond to the right and left wheels on my robot :-) However, I changed code and it is not responding. The reason I changed it in the first place is because I was getting responses from the Jaguar, but...

Have you enabled ssh in the raspi-config? I had similar issues and it wasn't until I completed all of the above s...

Re: RPi Cam Web Interface

Amazing! Just what i have been looking for. May i suggest, when you can switch between video and camera, that instead of recording when motion is detected, for camera, have it be able to take a picture when motion is detected.

Thank you so much!

So if i were out in the middle of a field with my pi and my laptop, I can still connect to it w/ssh. I have tried this tutorial, (http://blog.pistuffing.co.uk/...

Re: Measuring Velocity w/Ultrasonic sensor

I would suggest you print/display a few more of your variables and look for the cause. For example, when you get one of the high values, it would be interesting to check start_1 and start_2 to make sure they are really around a second apart (to eliminate random delay problems in linux), and distanc...

Re: Raspi with DFRobot Dual Motor Controller

I think it's probably safe enough. With PWM you will be able to give variable power to your motor. There might be a minimal pulse width/duty cycle to keep the motor running. I would experiment the library PiGraham suggested. Ok thanks, ill see if i can get that working. Ya right now im currently me...
