Animated snake eyes

Kyle pointed me to Adafruits Animated Snake Eyes. The software can be used withot any extra hardware. I had a spare Raspberry Pi 2, so I installed it. Pretty cool. Depending on your choises during installation, you can get either a single eye, or two.

Some weeks ago we discussed about an interesting project that is called HARK. 

It's an open source project created by Honda Research Institute in Japan.

A few videos that describes what can be done: 

Don't worry if you don't speak Japanese, I think you still will be impressed: Watch it and be impressed.

Movidius compute stick

I'm using the Raspberry PI3 as the "brain" in my InMoov. The main reason is that it's small and cheap.

I have successfully used the PI camera to stream video, and that works pretty well.

Depending on how you configure the camera, you can capture up to 90fps. So the camera is good.

Last weekend I, Markus and Robyn visited the Indian Institute of Technology, Rorkee in India.

It was a very interesting and inspiring visit. The people we met were very nice and asked a lot of good questions. Markus had his Robyn InMoov robot and I was bringing the head of my robot. We were showing the robots from Friday to Sunday and met a lot of interesting people. 

  


Aduino strange errors

Hi 

I sometimes ( not always ) get some strange errors in the Arduino service.

I think it is some type of timing issue.

Using this little script sometimes reproduce the error. 


DIY Gamecontroller / Joystick

Today I tested if it ws possible to use the small esp8266-01 together with two i2c boards to make a gamepad. It worked pretty well, except that I need to figure out why the response is slow. Probably due to the rest API, but it could also be some waiting for the A/D conversion.

Hi GroG

This is the error I get. The Arduino IDE shows the spash screen and then stops with this message:

 


This post is just for fun LOL

I started to test the Servo service to be able to make it work again.

I made some testing on version 1723 and the repeated the same tests on the latest version.
