Draw It OK. We've breadboarded the circuit courtesy of Mike Englehart and the fine people at Linear Tech so now we draw it using TinyCAD.  Again, you can download it by clicky da piccy. And now go to the menu and do Special->Create PCB Net List... Choose Protel format from the drop-down list box and make your filename 8.3 format. That is XXXXXXXX.net. Eight letters or numbers - dot - net. I've called mine SAstable.net and you can download it here if you really cannot be bothered to make your own. Here's an excerpt: [ C1 This part has no 'Package' attribute 10uF ] [ C2 This part has no 'Package' attribute 10uF ] [ J1 STB_2_L 2-Pin Header ] ( Positive D1-1 R5-2 R2-2 R1-2 J1-1 ) ( CollTR1 R1-1 TR1-3 C1-2 ) I've chopped a bit from it to show you. The bits in the square brackets refer to the components and are not very interesting. The bits in the round brackets are the individual nets. The first line past the ( is the name of the net. There follows the names of all the component pins connected to that net. It's painfully obvious really but the thing to take away is that you will use this on the PCB later so the names of the pins MUST match the pad names on the components. For example, if your transistor has 1, 2, 3 for the pin names on the schematic and E, B, C on the PCB then there will be errors. We don't want errors. |
