Hackers in our world, what is afk doing

rad1o

(find german version below)

After r0ket launching into the world of electronic name badges four years ago, this year we bring you rad1o.

We enjoyed seeing r0ket being used for all sorts of purposes, even years after camp, still in use with old and new ideas. With rad1o we want to go one step further and give you a Toy and Tool that will stay a huge, useful playground after camp.

Inspired by the HackRF, rad1o wants to give you access to the world of Software Defined Radio - the generation and reception of electro magnetic waves, controlled by software rather than analogue technology. Where previously large chunks of money had to be invested in analogue hardware, SDR can save quite some money and every camp vistor can become an SDR hacker. And if that's not what you're planning or looking forward to, please hand on the opportunity to someone else, e.g. in your local hackerspace.

With the rad1o transceiver you can send and receive between approximately 50/100 and 4000 MHz. Have a look what is going on in that spectrum (for example here)
If you got your hands on the HackRF, it's a quick switch to rad1o. The software is compatible. Exact specs will be available soon on the rad1o website:

Last camp we already were impressed by the large variety of projects using the name badge - but since we chose to surprise you with the first badge some projects were lacking the needed hardware (especially the micro-USB cables ...).

This time we want an even larger variety at camp! We tested our first prototype and we are optimistic that they can do everything we want to offer. While we now spend the remaining time until camp moving thousands of components accross the globe * and placing them onto PCBs, the challenge for you is to find things to do with rad1o! (* please, please wait a few more weeks if you fancy a few hundred of the components on our part list in your electronics lab)

If you have rad1o questions that are not answered in the wiki, feel free to contact us, ask questions and then fill the answers in the rad1o wiki.

You want to make your village something special? Maybe some of the objects you brought can be controlled via rad1o. Or you have some SDR riddles to solve with rad1o. Or you’ll use rad1o for transmitting… radio? or ...

For more fun and games with rad1o, we recommend to definitely bring a micro USB cable, and an external power bank will also come in handy. Additionally an external antenna might come in handy, see the wiki for details. For more blinking lights we added space for LEDs (WS2812B LEDs). We probably don't need to mention the opportunity for more crazy cases for the badge, right? :) (find CAD data in the Wiki, too).

BTW: If you like listening to the rad1o, you’ll need headphones (3.5mm standard mono headphones / microphone) or a 4-pin headset with microphone (like the Iphone standard).

After the r0ket start into the world of electronic name badges four years ago, there is a rad1o for all camp participants this year.

It was great to see how, years after the last camp in 2011, the r0ket badges were (and are) used for all kinds of purposes. With the rad1o we want to pursue this claim and offer you a gadget that will have a lot of hackvalue for sustainable further use long after the camp.

Inspired by the HackRF, rad1o wants to introduce you to the world of software-defined radios, especially for those who have not yet had much to do with SDR - i.e. the generation and reception of electromagnetic waves with the possibilities of modern software.
Where previously investments had to be made in complex analog technology, SDR devices have many more options, and very complex communication processes can also be implemented with little effort. During and after the camp, anyone can become an SDR hacker. And if you don't intend to do this, you can simply use other people's software projects for the rad1o, use it as an ARM microcontroller experiment board, or pass this option on to others - e.g. in the local hackerspace.

The rad1o transceiver can transmit and receive between approx. 50/100 to 4000 MHz. For example, here you can take a look at a typical SDR spectrum and see what can be going on there. If you have already experimented with the HackRF, you can simply use the rad1o with an adapted HackRF firmware. Exact specifications are still missing, these will be published by the rad1o team before the camp.

At the last camp, the variety of projects for the r0ket that were created at the camp was already impressive - but because we surprised you with the first badge, there was a lack of the necessary hardware for some projects (especially micro-USB cables ... ).

This time we want even more variety at the camp! We have tested our first prototypes and are confident that they can do everything we want to offer you. While we are moving thousands of parts through the world with all our might over the next few weeks * and placing them on circuit boards for you, you are now challenged to come up with something for the rad1o badge! (* please please hold back a few weeks if you just want to order a few thousand parts from our assembly list to your electronics workshop o.o)

If you have any questions that are not answered in the wiki, contact us, ask the questions and add the answers in the rad1o wiki.

Do you want to make your village something special? Perhaps a few objects that you have brought with you can be controlled with the rad1o. Or you can think of a few SDR puzzles that can be solved with the rad1o. Or you do ... radio :) or ...

For more fun with the rad1o, we strongly recommend bringing a micro USB cable, a power bank for more mobile rad1o fun is also highly recommended. In addition, an external antenna and an SMA socket (Spec, see Wiki) could be useful. For more flash fun, we have provided assembly options for WS2812bLEDs. We probably don't need to mention the possibility of making crazy cases for the badge, do we? :) (CAD data in the wiki)

If you like to listen to rad1o, you also need headphones (3.5mm standard stereo plug) or a 4-pin headset with microphone (corresponds to Iphone standard).

If you would like to hear schomal rad1o, you can download the recording of yesterday's broadcast from c-radar.ccc.de, where after about an hour a member of the team talks a little about rad1o.
