It's a bit small but looks fine.The two caps on the crystal should be 22pF rather than 10pF but that is not vital.
That's clearer, I can read the values now.Looks reasonable at first glance. What's your "sketch uploader"? I assume you've knocked up an adapter for an FTDI cable or some such.The uSD may clash with ISP programming but that's easy to remove.Any reason for using two 1k resistors for the LED2? I sometime do that to reduce the number of different components but I can;t see that being an issue here.LED3 only has a 150R resistor, that's different to the 500R LED2 has. Different Vf on the LEDs?______Rob
Keep in mind, when calculating crystal capacitors, load capacitance isn't the target capacitor size, it's part of the equation:C1 = C2 = 2 * (CL - CP)Where C1 and C2 are your two capacitors, CL is the load capacitance in the crystal datasheet, and CP is the parasitic capacitance of the circuit.CP is such a small value, and very difficult to know in advance, that I usually figure it being somewhere between 5 and 8pF. From what I've been able to see, this is pretty typical. As long as it isn't wildly off, you'll be well within tolerance specs of the capacitors anyway.
what do you mean by the possibility of clashing between the ISP and the uSD
