Super Easy AVR Assembly Programming

From this May on, I somehow got interested again in assembly language. It's been more than 25 years since my last assembly programming, during and a bit after my university years. I've been playing around with the Atmel’s microcontrollers for some time now, so I thought I would better try something with them. A simple Attiny13 blinker for instance ... My previous experience on assembly language, apart from being ages old, also concerned (as might expected) an ancient chip ... the 6502 microprocessor. Who really knows about it know? ...

Simple SMPS schematics and projects from Internet.

Recently I've been reading about the various types of SMPSs. These are designs which I haven't been taught about during my college years. I got interested in them and I did some research on the Internet. Some simple designs for DIY projects caught my attentions, so I copied them on Ms-Word files to print and read carefully.
So here you can find this files if you are interested.

All the material comes from the Web. You can easily locate the initial source if search for them with Google... You can just download them from here to save time...  Please note that no design has been tested.

Be reminded that these designs are for circuits directly connected to the mains and therefore constructing them is Dangerous!!!
