Hi to everyone:
I´m Sebastian and a few months ago I was really surprised about the power of this kit but a few hours ago it stopped working so my first impression was that the green led was not working but the IR led´s were ON all the time (this was observed with a camera) so when I removed the micro and connected the 4 and 7 pin the green led turned ON, weird isn´t it?
So my question is...Can the micro fail just like that after working perfectly for months or something else could have happened?
I´ve been checking the other pieces but transistor, crystal and LED´s seems to be in perfect conditions...
Thank you very much for all your knowledge
P.S: does anyone know if the blue crystal can be replaced with a 8 Mhz micro controler like this one http://www.olimex.cl/product_info.php?c ... cts_id=236
Thanks twice
Greetings

Re: Micro problem
it sounds like something was shorted or maybe the batteries are dead. chips dont suddenly 'die'
also check if anything got knocked loose

Re: Micro problem
Well, I´m gonna check every component, part by part, i know that the 2n2222 transistor from de IR LED´s can be replaced for any 2n2222 transistor but could I replace the blue crystal for an external micro controller crystal like the one I posted in the link of the last post?
Thanks...
Thanks...

Re: Micro problem
we'd check eveything else before replacing parts. its unlikely a part went bad
