Transistors

I use Microsoft Paint program to draw schematics. Straight lines are made with the Shift key down and most devices are copied and pasted from other schematics in datasheets.

The reason for all this is that to learn about radio, digital timers, amplifiers and tone detectors I decided to make a weatheradio that detects the alarm tone and begns to speak and turns off after 3 minuites wether you turnit on o if it was automatic.

I did this for a long time, i wasn't really satisfied because it took me a while, and i couldn't simulate the circuit so i bought livewire, things are easier and faster now.
