Hello forum members, Recently i readed a reply of P.erasmus: here

This triggers the idea to collect any hardware subject's at this list,
therefore this gives the members opportunity to easily find them back at the future.
Feelfree to post usefull hardware subject's here...

Great I dea and I would like to ask the experienced people like Artic ,dschabel please support this Forum
and not fogetting Stefan
we all l need to learn and understand hardware circuits to work effectively with the controllers in our projects
Thanks Neiwiertz for starting this Forum

Hallo Guys
I have gathered some useful things on the Mosfets
the only problem is that I can not upload a pdf file or is it possible
regards
Peter
 
ok I added the links to the documentation

Hi all ,
 
Nice collection and good idea , I would be happy if you accept my 5V-3V interface circuit that I use and it is ok  grin.

this is a simple DC/DC converter for, you maybe know, areas where no microcontroller and no DC/DC converter have been used before.
Duracell (9V batteries) and ST (7805 regulator) will maybe not too happy, but it is just a proof of concept.
 
it can power a 16F54 flashlight for about a week, i do not know, it is still running since i built it, one single AA battery (1.2 volts).
 
normally you should use those special ICs (LT1073), but take a look anyway.
 
by the way, if you use http://multiply.com for instance my PIC group http://picsystems.multiply.com you can organize knowledge with tags, for instance, the type of PIC!
