More planning? I would like to know how to build and programm an avr microcontroller. I would like it to recive and send some data when working. This is some basic stuff for narmal pragrammer, for me it is new thing. I have been thinking about that some time and after reading some sites and books I figured out what elements should bo connected on a pcb fulfiling those requirements.

• ATMEGA32
• power supply section
• RTC hardware timer
• FT232 chip
• LM35/DS18B20 termometer(s)
• DHT22 sensor
• battery

Now I should check all diagrams, before preparing the PCB design. I propably will make the pcb on perforred part of thin steel. Then I will solder sockets and necessary passive elements.
