|In a hackerspace a computer is needed everywhere, included behind the bar. So this project was born.|
- In a bar we need music. So we'll set up an MPD server connected to an amplifier to allow everyone to play there favorite music.
- Where we sell beer and Mate Point of sales and Stock management software seems obvious.
- The person running the bar might also want to follow talks going on in the other room. So the system should be able to display webcasts.
What we have available
- Speaker cable
- CD-player (optional)
- Old laptop (2,53GHz Pentium IV)
- Serial barcode scanner
- a Elo-touchscreen, serial port , 17"
Thanks to all who have contributed hardware!
- Hang the speakers (done)
- Find a permanent location for the Amplifier & CD player behind the bar (done)
Point of sales & Stock management
Using the Jostokassa application made by Koert
I'm writing a new one (with a gui because console + touchscreen is just silly) more suited to our specific needs -- Koert
It might be convenient to use a touch screen at this location. Rob has provided a old LCD touchscreen we might use. To get it running on ubuntu (testet on 10.10) you need the following driver to be installed:
sudo apt-get install xserver-xorg-input-elographics
After that you need to add the touchscreen to you're /etc/X11/xorg.conf file. This was done according to the configuration found here: http://0x20.be/Table_Computer. Restart X-server and you should have the touchscreen working. The values in the xorg.conf must be calibrated to you're specific configuration. At this time I haven't found any other option to do this then trail and error.
Take a look at touchcal. I haven't tried it, but this should help you calibrate elo touch screens (Koert)
- A computer has been fixed to the ceiling above the bar
- The touchscreen is operational and calibrated to a usable degree.
- We are currently using the cash register thingie I (=Koert) wrote for Josto. This is text-based so atm the touchscreen isn't of much value yet. I am however writing another program, with a GUI, more suited to our specific needs.
- So as from now: if you buy a drink, scan it! If for some reason you can't figure out how it works, ask Koert.
- Still to do: mounting of the touchscreen on a somewhat, "ergonomical" height. I plan to do this next wednesday. I'll be looking for materials this week(end). Some plywood and iron stuff will do the trick. (Tom).
