My standard test on how hackable a device is involves getting Guile running. Anyway, it was pretty easy to accomplish this despite not using openWrt before.


root@BenNanoNote:~#
root@BenNanoNote:~# guile
guile> (map (lambda (x) (+ x 1)) '(1 2 3 4 5))
(2 3 4 5 6)
guile>


To install get the 3 xburst packages from here.

Happy Scheming!

Tarball: http://zedstar.org/tarballs/square-0.1.tar.gz

ipk: http://zedstar.org/ipk/square_0.1-r0_armv4t.ipk

After installing Guile do:

root@om-gta02 ~/ipks $ opkg install square_0.1-r0_armv4t.ipk
Installing square (0.1-r0) to root...
Configuring square
root@om-gta02 ~/ipks $ square
result of square is 49
result of square2 is 81


I am very impressed how things have progressed especially in terms of being a phone!

Anyway, this gave me a chance to try out some Guile packages I built. If you have a recent version of SHR unstable the following should work:

From the README:

A simple GLib based program which periodically reads coordinates from gpsd.

The logs directory contains a sample gps log which can be fed to gpsfake:

gpsfake 1334-N-20071129-GTA01-A3.log

Make sure gpsd is not running before attempting to run gpsfake.

The data was taken from a Neo 1973 in central London. It will take a moment
to start showing coordinates.

Fire up eclipse:

1. Help->Install New Software
2. Click Add
3. In location add: http://download.eclipse.org/tools/cdt/releases/galileo

You should be able to select this now from the drop down box titled “Work with:”

Follow it through and it will install what you need. My previous C/C++ view was ghosted so I added it again.

Binary: http://zedstar.org/deb/btlogger_0.3.3-1_i386.deb

Tarball: http://zedstar.org/tarballs/btlogger-0.3.3.tar.gz

Repo: git clone git://gitorious.org/btlogger/btlogger.git

Take a look at the README for further information.

http://zedstar.org/tarballs/sneektweet-0.1.tar.gz

The readme:

sneektweet 0.1:

Wraps some C/GLib code which posts to Twitter.

setup:

Edit configure.ac to set twitter account details.

from REPL:

john@thinkpad:~/workspace/sneektweet$ guile
guile> (use-modules (twitter sneektweet))
guile> (tweet "foobar")
guile> ** Message: posted update to Twitter

todo:

Add reading updates and posting back to IRC channel. 

bobot example code:

(use-modules (twitter sneektweet))

(define (sneektweet channel message)
  (if (> (string-length message) 140)
    (bot:say channel "Your message needs to be under 140 characters in length!")
    (tweet message)))

(bot:addcommand "tweet" sneektweet #t 2 0)

This programs calculates the covariance of data sampled from a Thinkpad’s accelerometers. If the covariance is over a certain threshold it posts the result to Twitter. Or more simply put, shake your laptop and make it tweet!

It is a command line program which requires a Twitter username and password to be supplied e.g.

shakeyshakey -u foo -p bar

Built and tested on Ubuntu (Jaunty Jackalope).

http://zedstar.org/tarballs/shakeyshakey_0.1.orig.tar.gz

http://zedstar.org/deb/shakeyshakey_0.1-1_i386.deb

It is a command line program. An example of usage is:

geotwitta -u foo -p bar --lat=55.55 --long=-0.25

This would authenticate against the Twitter account ‘foo’ with password ‘bar’ and ping in those coordinates. These account details are only exchanged securely with Twitter and not sent over the network protocol. The protocol also does not provide coordinates back of other users. It simply shows a relative distance. The full source of the client is available. If there is an interest I will also tidy up the server code and release it.

To get started you need two packages: The program itself and the Guile module which does the network protocol work. The following tarballs are availble for those who want to build from source.

http://zedstar.org/tarballs/packedobjects-0.1.tar.gz

http://zedstar.org/tarballs/geotwitta-0.1.tar.gz

http://zedstar.org/tarballs/geotwitta-0.2.tar.gz

Untar and do the usual ./configure… routine. The configure script will let you know which dependencies are required to compile. If you don’t feel like building from source I have also built some Debian packages. I have tested these on Ubuntu (Intrepid Ibex).

http://zedstar.org/deb/packedobjects_0.1-1_i386.deb

http://zedstar.org/deb/geotwitta_0.1-1_i386.deb

http://zedstar.org/deb/geotwitta_0.2-1_i386.deb

If you manage to get the software running I will see you on Twitter!

All the usual disclaimers about the software apply.

**update**

Version 0.2 of geotwitta added: ignores UDP packet loss on pings

http://zedstar.org/deb/btlogger_0.3.2-1_i386.deb

After installing run btlogger –help
