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? ...

An interesting site on electronics and some files to print

I’ve been playing with electronics since I was a teenager. From those days, during the fabulous 80’s, there are many things that have changed scientifically in this field. But still some circuit designs can endure the test of time. Such circuits are fine for experimentation for the everyday hobbyist.

Although I had acquired some formal knowledge on electronics and electricity in general as college student, the information I find in some selected sites on the internet is really invaluable. One such site I distinguish is this: Talking Electronics. If you are interested in electronics before the days of Arduino read on...

Alkaline battery regeneration (Simple circuit 1)

Introduction

Children's toys devour nowadays tons of battery power. It's heavy for the purse - especially with alkaline batteries. Although these last much longer than the conventional zinc-carbon batteries, they come at a price.
