Re: EtherTen running hot

Yes, 12V is at the upper end of what you'd want to run. The EtherTen has a linear voltage regulator that sheds excess power as heat, and it runs at 5V so it needs to shed 7V from a 12V supply. I don't have an EtherTen in front of me to measure, but if it consumes (say) 200mA for the board itself plu...

Re: Arduino Due with Ethernet

It's been a while, but you'll be happy to hear we're doing hardware prototypes now for the EtherDue - which is exactly what it sounds like! The final production version should be available in about 6 weeks.

Re: Lighting control 12v switching vs 240v switching

nitrolx, have you made any progress with your construction? I'd love to see the results!

Re: Usb Boost

This is done now. The USB Boost product page now has links to the Quickstart Guide, the design files, and to this forum:

Re: Usb Boost

Oops, sorry about that! It looks like Jaycar were super-efficient getting them out to their stores, and caught us not quite ready.

I'm working on a user guide now, so it should be up in a couple of hours. I'll let you know when it's done.

Re: How are the nice fonts on the Eleven Eagle layout done?

Yes, the ratio setting does make quite a difference to the appearance of the text. I tend to use 15% almost exclusively because it comes out looking less spidery than the default 8%.

I'll be interested to see your shield when it's done!

Re: How are the nice fonts on the Eleven Eagle layout done?

I don't know that there's a secret recipe I can give, because as far as I know we're just using default fonts in Eagle! I've just opened the Eleven in Eagle myself to check the settings, checked the properties on one of the text labels near the top header, and these are the settings: Mirror: off Spi...

Re: EtherTen running hot

USB power definitely bypasses the onboard regulator, but the voltage can still be marginal sometimes because of voltage drop across the USB cable. One of the major sources of heat on both the EtherTen and the EtherMega isn't the voltage regulator: it's the Wiznet Ethernet chip! The W5100 is well kno...

Re: Multiple probes for iButtons...

Could you please give a bit more detail about what you've done so far? Info such as what model iButtons you're using, what code you're using to read them, how you've connected the probes, etc.
