below the minimal setup with a lcd display and serial connection

just checking on sd/mmc card information, looks quite promising, having a lot of cheap storage space for different types of measurements :)

currently another rather not bot related topic

state of the longterm-ecg- prototype : http://johannes.lampel.net/pics/IMG_0825.jpg

Re: bots in real life
 

Well Well Well
so you want to build a real mechanical bot!:nuke:
Actually that's every freaky bot programmer's dream including me! just Wow imagine , what you could do ..... like getting an army:gunsmilie: of those little machine-heads and conquer the World ...MUhahahahahaha:devil2:
but seriously : I think that anybody who plans such an ambitious scheme should first of all worry about HOW you gonna physically construct the mechanical body of this robot ....
however the programming of the robot would be the most easiest part , at least from my angle of view.

anyways , they say that imagination rules the world:)

Did you remember to put 0.1uF capacitors near the digital ICs from their power to their ground?

Re: bots in real life
 

yep, sometimes more ... and sometimes even an inductivity for the really stable parts :) ... the black little boxes on the left there do not need any caps, since it's only 2 optocouplers :)

Re: bots in real life
 

Oh, I thought they were some kind of logic device. Well, I guess digital IC still applies then, and some analog ones, also.

If you use two power supplies, you can reduce the need for those.

Re: bots in real life
 

AHHHH excuse me if I'm standing stupid 0_o in this thread , but what is it exactly that you're constructing that takes all this Hi-tech ?
a water pump? , a Robot? or a water pumping Robot?............Or is it a Water pump that playes counter strike while pumping Water??

Re: bots in real life
 

yeah, that might be an application ;)

currently i'm just getting to know that stuff better, currently i'm building an ECG, which already produces nice results, though just one channel until now

once again a picture ... just soldering the 3channel ecg :)

Did you know you can make PC boards with photo paper and a laser printer? Well, I mean you will still need etchant and the copper clad. You can make the etchant work better with a fish tank heater. You don't want to use something that gets really hot, though. You can also you an air pump from a fishtank to accelerate it.
