Thanks again to Ray's suggestion, I purchased a $9.00 DC-DC buck converter from Amazon - which will be powering all the 12v devices on Work-E such as the wifi router and the kinect ... Progress !


MotorControl and MotorController - Range Mapping, Min Max, Input Output

GroG's picture

One of challenges with the old mapper was what to do when setting new values of min & max.
In the above diagram we see a range established by a min & max. 

e.g.  mapper = new Mapper(-1, 1, -1, 1)  

min & max input will be -1 & 1  .. min & max output will be -1 & 1

Hello!
I'm going to use a remote control and wire the buttons, to detect when someone opens the refrigerator or the cabinets.

New Tracking Algorithms, TLD, MedianFlow, and More!

So, in OpenCV 3.x there is a new opencv_tracking module that is exposed via JavaCV. 

This module contains 7 different implementation of object trackers.  There is a new "Tracker" filter that allows you to switch between any of these 7 tracking algorithms.  It should work pretty similar to how the lk tracking works in that it should publish the point that's being tracked.  Right now the filter only supports tracking a single point.

MarySpeech on Raspberry Pi

XRobots's picture

I'm finding that MarySpeech takes a while to start up on a Raspberry Pi - at least a minute before it starts working. Also sometimes the speech is broken up if other things are going on like setting digital pins using an Arduino and the MRL service.

I also tried to install destival and use localSpeech but that is just silent, not sure what I've missed. Does anyone have any tips or anything else that's working?

 

thanks

In a Nutshell :-


Virtual Joysticks are Un-Breakable ! .. (mostly)

GroG's picture

It took "too" long, but I got virtual Joysticks working ! ...  
To be precise, any device (joysticks, gamepads, keyboards, touchpads, .. etc) which the Joystick service can see can now be "virtualized".

Ok, so what the hell does that mean ? :)
