RTL-SDR

GroG's picture


A pretty fun diversion (squirrel !), Listening to country music ... that seems to be most common in the lower frequency bands with a RTL-SDR 

Gareth turned me on to it. Linux install was pretty straight forward.  Digital packet over low band ... hmmmm.... slow but nice range

Hello gents! I was wondering if anyone has had any results on getting the Leap motion service up and working on the latest version of manticore? I am running via a PC incase that helps solve anything. I read that mac requires a little bit more set up to get leap motion working but not really sure. :9

For years I have eye'd this library with the idea that it would be a great service for mrl.  Ray I believe is interested in creating an new mouth service for InMoov.  I think we are both thinking of the possiblity of monitoring the output line and generating events to move the mouth appropriately.

PID Loops

Proportional, Integral and Derivative or PID control systems have been around for a very long time, but they are still not very well understood.

Recently I convinced Fred to give a bit of a talk on the subject.
Good thing with robots, is convincingthem is just a case of programming them :-)

Here is the video of Fred's presentation.

"Peri-Scope up" - FNIRSI-1013D Portable Oscilloscope 100Mhz(!!)

Gareth's picture

I just bought one of these, thought I would bring to your attention :-

Best part ..... its circa 120$ delivered including two x1/x10 probes ..

(-: bonus for me was that the customs elves were on coffee break :-)

In a nut shell its a Dual channel 100Mhz with 7" colour touch screen.

The performance drops off the more you lean over 80Mhz. (100Mhz is bit tongue in cheek, however how often do we need to measure so high)

Using Mimicspeech on the Raspberry Pi

Ray.Edgley's picture
Before we can use Mimic speech with MyRobotLab on the Raspberry Pi, we first need to install it.
The compiled executable is installed with MRL for windows, but not for the ARM based linux install used on the Raspberry Pi.
