Spoke too soon - the Append isn't quite what I needed since Eagle will still run a ghost wire between the two pads and expect them to be connected with a trace, whereas they are electrically connected on the physical device, so the trace is unnecessary.

I looked at the @ option too but that seems to require a symbol pin for each connected pad. The example I have is a battery holder, so obviously I want a standard 2 pin battery symbol for the circuit...

Ah yes - append what I needed - screamingly obvious when you know!
Thanks

Thanks!

Another Eagle component library question - if you have a package that has several pins all connected internally together (multiple grounds for example) is it possible to connect these all to the same pin in the device / symbol?

The pins to pads connection process seems to be a one to one relationship. I tried renaming the pads to the same name but it won't allow that... is there any other trick?

Cheers

Just to clarify - this is not about making an irregular shaped board overall, it's about including slot / milling info in a specific component in the library, so every time you place the component you get the extra milling.

It 'seems' to work if you just draw wires on layer 20 in the package design (from looking at the Gerbers), I just wasn't sure if this was a 'legal' thing to do...

Is it possible to define a board cutout in a library part that is not just a round drill hole? More specifically a square hole or slot?

Would just drawing a shape on the Dimension layer be sufficient, or is this going to be down to the fab house in the end?

Is there any reason the LEDs on pins 15-17 have 4.7k resistors? This will only give you about half a mA through each, they will be very dim when on.

Also I'm not sure if the circuit was just drawn freehand or with a design package like Eagle, but you appear to have signal lines going through the 2 crystal caps (aside from issue already noted) - may be cosmetic, or may be a bad connection...

Traces look a bit fine to me - may be within the minimum, but I always err on 'comfortable' if you really don't need minium. Also some sparation distances are smaller than they need to be  - you've got traces coming off the pinheaders at cangles that take them close to other header pins when they don't need to pass that close...

Is the idea really to have the LEDs on the RIM of the wheel ( NOT down the spokes)? To gain the illusion of a ring of light around the rim as the wheel is going round? In which case a) you don't need any micro control and b) you probably don't need anything like 50 per rim to get a nice ring illusion at any half decent speed - probably 6 would work great and save you a ton of power....

Check out the SoftPWM library - not only will it allow you to PWM all the pins, but has built in support for fade up and fade down of values over time, which is exactly what you need for such an application

Sorry for not getting back -  I need to pick this all up again soon as I'm now trying to modify it for the Tiny85.

Glad you got it working but keep an eye out if you are trying to control a lot of outputs as the 2313 runs out of RAM before you run out of pins!

Just what I was looking for! Thanks!
