ATtiny servo control

 

After a brief discussion with fellow LMR member Maxhirez, about his Hedwig robot,
it seems as though there isn't much support for servos in the ATtiny family of
microcontrollers. After fighting with the 8-bit servo library I found HERE that was
supposed to make it as easy as a standard Arduino to add servos to an ATTiny project,
Navigate around via IR, avoid stuff.

It is my first homemade robot with microcontroller. I found some schematics in the internet and made some changes. It is controlled with Attiny 2313, robot has two … Read more

Timers and ... stuff

Hi all!

Been pretty busy lately digging in the big black timer.pngmystery box called Timer  on those nifty AVR controllers.

I think I finally have a clue how they work, and more then that, how they can be put to good uses. 

One application I'm going to do now that I have a clue, is to (try to) do microstepping. Yeah I blabbered about that other times too.

The Valkyrie

Hi all!

So the Beast is dead, buried, gone .... I actually intended to keep it as it was but hey I needed the parts :)

The new machine (Valkyrie) is basically completed and since the keyword for this one is ADJUSTABLE I still have to adjust things :D

Will start soon a new robot page for it ... stay tuned.. 

DIY CNC Part II

2 more draw slides to use for the Y axis purchased from here. High quality slides with ball bearing inserts. Still have to work out how I want to mount them. They were only $15 each.. money well spent now that I can see them close up.
