Thank you Adilson here's the board that I've made:
not yet finished though, I still haven't received my atmega168 and crystals
please comment, correct, if what I've done is okay, not good (newbie here)
While waiting for the 168 and crystal, I decided to do some tests.
1. I plugged in a 9 volt battery, and measure the voltages in 5V and 9V, pins 7,8, 20, 22 of the 28 pin IC socket, and pins 2, 5, 6 of the ICSP header. All are okay and registered ~+5V.
2. Next I decided to test the RS232 TTL circuit, by setting the serial enable jumper. Measured pins 2 and 3 (on the IC socket) and the voltage is +5V, then I jumpered them, this is where I kinda (scratch head) ask the forum for comment. Well, the RX and TX LED should both light up right? but on mine it did not right away, it takes a couple of seconds. Sometimes not at all.
3. I also plugged to my computer open hyperterminal. With pin 2 and 3 jumpered when I press a key on the keyboard the RX/TX LED lights up as it should. Un jumpered it, and only the RX led lights when I press a key on the keyboard.
Is there something wrong with my board? Especially with the #2. I've checked all connections and all are okay.
Thanks very much! Can't wait to start uploading sketches to my Severino.
