This can be understand with difficulty by nowadays computer guys, however imagine that it was an era when there wasn't any computer and homebrew PCB was manufactured by hand using a nib and ink (carmine ink). In that days manufacturing a PCB with 10 integrated circuits onboard tooks for me about 8 hours. Another trick you can use (and I see nobody did here, or at least didn't show) is to create a "heart" design, which match with various applications. Is much better than using jaluino/arduino/picolino because can be transfered from one project to another using copy and paste. In this fancy way you don't have stacked boards or other silly solutions which can blench your hear. Any time when have to design a project using for example PIC64F2011, you copy the "heart" and put it on your new design. The same with pheripherals (SD card, I2C memory, USB, USB/RS232, stepper driver etc). Designing a board is less painful than writing the code (at least for me), anyway you all know that a good code has at least ten-twenty revisions since works as it shout, while a good PCB has only one. The key is: "don't rush!". work with joy, Vasile > -- You received this message because you are subscribed to the Google Groups "jallib" group. To post to this group, send email to [email protected].
