I'm working on making a non-strip board PCB of a quiz circuit that i saw and need to make sure that i transfered the Schematic to PCB correctly.

I have the PCB file below to modify anything that is wrong and send it back. along with the SCH file and the link to the SCH on the web

web schematic (http://www.kpsec.freeuk.com/images/quizcd.gif)

Use the updated version of Express PCB and Express SCH

{UPDATE}
I moved some traces around in the PCB file. Also i renamed some of the resistors so they would fit inside the resistor shape.

I forgot to mention that Red is jumpers not a bottom trace.

I did see an error with my pcb. I added another jumper (12) and connected it to the resistors and the Neg of JP1

Pin 4 of U1 and U2 are only connected together, not to anything else. According to the schematic on the web, it is supposed to be a reset, only tied to a reset switch and a 1k ohm resistor. In your layout, it is also tied to a cap and an inductor?? (H2??)

Ok thanks. The resistor (h2) is labeled that cause there are 3 sizes of resistors(low, (r) medium, high).


I fixed that one reset problem.
