AVRFreaks Meetup

I forgot to write about this the other day, but better late than never. Last Monday we Melbournians had our first (of many?) real-world meetups where several AVRFreaks members got together for a drink and a chat. I had a blast of a time, and it was great to finally put some names to faces in the AVRFreaks community. Turnout was good, with eight or nine people braving the 43 degree (Celsius, not Fahrenheit!) heat outside in the city.

I must say, it was both fascinating and odd to be talking to people who you’ve only met over the internet; it was a sort of surreal bleeding from one world to another. That said, all the members were very engaging and I hope there will be many similar meet-ups in the future with more people attending. One thing that shocked me the most was that one or two people actually mentioned things I’ve written here on my blog – I wasn’t aware that anyone actually read the junk I put down here; I’ve been using it mainly as a brain dump to ease the mental pressure. I’ll have to be more careful what I write in the future.

I hope Neil will forgive me for appropriating his group shots so I can post them here. I’ve labeled everyone with their first name and AVRFreaks username, so you can put a name to the, well, name. Click the photos to enlarge.

Awesome. One of the highlights of the night (for me) was the personal demo Mike gave me of his pet project – a LUFA USB host connecting to and downloading a webpage via a Three Mobile Broadband USB modem. There’s a heck of a lot of work he’s put in there to get it all up an running, including mashing LUFA, a set of PPP code examples, a TCP/IP stack and a lot of glue logic together to make a small unit of pure awesomeness. With a bit of cleanup it could become very useful for mobile units in the field, downloading updates straight from the internet wherever there is mobile coverage. Let’s see people do THAT with a Zigbee :).

That usb-ppp app sounds amazing.. Does Mike plan to release under any kind of free license, or is he planning to keep it closed? 🙁

 

It was amazing to watch, trust me :). Yes, he plans on open sourcing it, once it has gone through a lot of cleanup to get it fit for general consumption. He’s already sent me the code, which I’ll have to clean up, remove the hacks, document and present as a standard LUFA demo.

I would like to make my own mkII clone using your software. I see in the make file I can use my own board. Will I only need one of the atusb micro’s with a usb connector or is more circuitry required?

 

In it’s simplest form, that is all you need. For additional features (level shifting, short circuit protection, etc.) you could add in external buffer ICs and the like, but for straight 5V programming the bare AVR and USB circuitry is all you need.

Excellent. I will have to get a usb chip when I make my next order of electronics fun.
