 ===== WindClock-III ===== ===== WindClock-III =====
  
-==== sinterklaas 20161206 and time to boot up that rpi: ====+A full description of how to make and install your own WindClock-III will be provided here in time. 
  
-  * format problems SD from OSX solved with +// Current prototype development state: // 
-  * http://michaelcrump.net/the-magical-command-to-get-sdcard-formatted-for-fat32/ +  * installed a raspberry pi 3 with a sensehat again, after messing up with python 3.5 
-  * downloaded and copied 2016-11-25-raspbian-jessie on the sd (64G)+  * python coded all data for realtime request available in a file 
 +  * managed to install a couple of working online transfers with the new websockets/html5 protocols (finalizing is and now testing websocketd which is promising easier connectivity) 
 +  * also working on an enviro phat hat with a zero pi w
  
-==== the day after 20161207 ==== +// Future work: // 
-  * boot up the rpi +  * adding a waterproof temperature and ambient light sensor by extending the sensehat header pins 
-  * upgrade and update +  * power: 5V-2A for the pi seems too much, so would use a Teensy with 3.3V 500mA (windclock-iv) 
-  * install sensehat+  * designing a shape/case for hanging it up and responsive to wind (physical calibration) 
 +  * simple visualisation/sonification on the object (python will do, maybe puredata too) 
 +  * work with more than one windclock (but keep it under 10 haha) 
 +  * client-side for data capture (katastrof interpretation and sonification) in various programs
  
-==== testing 20161208 ====+// Make and install the real objects // 
 +  * rodchenko examples (see below, as a starter) 
 +  * gtr-lahaag'z ultimate design: in [[http://atkn.org/wiki/index.php/Mxhz | the atkn wiki]] 
 +  * I would just cut out a spiral out of a thin wooden plate and stretch from the middle up 
 +  * we'll ask more people and try them all out? that is greater fun! 
  
  
-ssh and vnc (see below, troubleshooting) +More details and progress the coming weeks...
-went through all the features +
-calibration! https://www.raspberrypi.org/documentation/hardware/sense-hat/ +
-   it is in the folder /sensehat/RTEllipsoidFit +
-   startup by typing in console: RTIMULibCal +
-   going through all sensors / python: till Detecting movement +
-   https://www.raspberrypi.org/learning/getting-started-with-the-sense-hat/worksheet/ +
- +
- - made a correction in calibration temperature  +
-   problem the cpu temperature is preventing a correct reading +
-   changed it to ((temp - cpu temp) * 0.75), but should be better calibrated +
-   I guess doing (temp - cpu temp) would be enough and never accurate anyway +
-   (adding a waterproof temp. sensor would be better...) +
- +
-testing 20161209 +
-* - want to do ssh and vnc! (working now) pi + pw: timeinventor000 +
-    +
-   put an ethernet cable between my mac and my pi and .. ah.. no problem +
-   scan live hosts on network: nmap -sn 192.168.1.0/24 +
-   started up X11, ssh-keygen -R 192.168.1.14 (or any other pi address ip) +
-   ssh -X pi@192.168.1.14  +
-   sudo apt-get install xrdp +
-   sudo raspi-config (enable boot to desktop -- console, text console, requiring login) +
-   (if you want GUI then type on rpi 'startx') +
-   --> also this all works now from the terminal on the mac, no problem +
-   Filezilla works as well with the sftp protocol!  +
-    +
- - also fixed the temperature readout calibration and added the  +
-   get_temperature_from_pressure (default it is using the humidity sensor) +
- - try to boot with power from usb cable? does not work of course..  +
-   +
-testing 20161211 +
- (just need a wifi connection) +
-* (scan for the pi on the network: nmap -sn 192.168.1.0/24) +
- (start up with ssh -X pi@192.168.1.14 from the terminal on mac) +
- (start up realvnc client on mac, if needed sudo raspi-config and enable vnc) +
- (to turn off matrix led terminal: python3 shutoffmatrix.py # script in sensehat folder) +
- (sudo shutdown -h now) +
- +
- - continued with Detecting movement (pitch-roll-yaw) +
-   https://www.raspberrypi.org/learning/getting-started-with-the-sense-hat/worksheet/ +
-   additionally +
-   https://www.raspberrypi.org/learning/astro-pi-guide/sensors/movement.md +
-   again checked all sensors (see above, can be done in python, full code:) +
-*   https://pythonhosted.org/sense-hat/api/ +
- +
-testing on xmas +
- +
-done: sudo apt-get install ipython +
-done: sudo apt-get install ipython3 +
-done: bring together 9DOF and the tph files into 1.. +
-done: wrote data in a file 'test-9DOF.txt' with this easy example, it works!  +
-   how I like simple things hihi +
- name = "John Smith" +
- pin = 1234 +
- file = open("test.txt", "w") # write +
- file.write(name+"\n") +
- file.write(str(pin)+"\n") +
- file.close() +
- # keep this for reading out.... +
- file = open("test.txt", "r") # read +
- name = file.readline() +
- pin = int(file.readline()) +
- file.close() +
- # print name, pin +
-  +
-here are more complex examples-- from the https://www.raspberrypi.org/resources/ +
- https://www.raspberrypi.org/learning/sense-hat-data-logger/ # write to files, on bootup, ... +
- https://www.raspberrypi.org/learning/temperature-log # write to file, visualize pyplot, cron +
- +
-Testing on 2nd XMAS: SENDING DATA TO PC +
-   + sounds like the simplest solution:  +
-   http://raspberrypi.stackexchange.com/questions/12955/how-do-i-send-data-from-the-raspberry-pi-to-the-pc +
-    +
-   done: installed webpy in a new folder on the pi, the executable is delivering messages +
-         running the server from the folder with command: ./server.py +
-         from pc connecting over browser http://192.168.1.13:8080 +
-   had to change the script of server.py +
-   but now can read files in the 'static' directory +
-#  (which can be dynamically updated with data, but isn't that a bad solution? at least accessible) +
-#  later can read it on the pc with the following python code +
- import urllib +
- link = "http://192.168.1.65:8080" # Change this address to your settings +
- f = urllib.urlopen(link) +
- myfile = f.read() +
- date = myfile.split(" ") +
- +
- Also done this:  +
- http://thisdavej.com/make-your-raspberry-pi-web-server-available-on-the-internet-with-node-js/ +
- start up the server with terminal command (Public folder is serving files) 'http-server' +
- http://192.168.1.13:8080/  +
- did not bind it to port 80 (sudo http-server -p 80) +
-  +
- then installed localtunnel +
- so, you have to get http-server running and then launch localtunnel as following e.g. +
-* sudo lt -p 8080 -s windcl0ck -o +
- then you can access worldwide https://windcl0ck.localtunnel.me +
- +
-WOW!  +
-found out when starting the http-server from another folder then it is taking this folder as a starting directory!!! great - just start it up where the files are hihi in my case the sensehat directory +
- terminal: http-server +
- terminal: sudo lt -p 8080 -s windcl0ck -o  +
-           #change the number in the name for any windclock-III-pi  +
- haha make sure the python code is running hihi +
-YIPPEE!  +
- +
-but also tried to fix the fact that localtunnel was interrupted by some sleep state +
-http://raspberrypi.stackexchange.com/questions/4773/raspberry-pi-sleep-mode-how-to-avoid +
- +
-- sudo iw dev wlan0 set power_save off +
-  (did not help much) +
-- edit in /etc/kbd/config: POWERDOWN_TIME=0 +
-  (did not help much) +
-- changed startup of xserver in /etc/lightdm/lightdm.conf +
-  [SeatDefaults] section, xserver-command=X -s 0 -dpms +
- +
-Finally wrote a client page to send around for people to test the data...  +
-Windclock-III-Hranice.html +
- refresh and <object> for inclusion data .txt +
- +
-somehow it worked and then not anymore ai ai ai  +
-tomorrow more??? +
-yeah I think this tunneling is very unstable, unreliable -- so switch to nginx? +
-first trying to get a stable internet connection and work headless +
-but localtunnel does not want to boot up without X environment!!!! +
-and there is a bug with localtunnel dropping out +
- +
- +
- +
-- ai so better go trying  +
- http://raspberrywebserver.com/cgiscripting/setting-up-nginx-and-uwsgi-for-cgi-scripting.html +
- +
-- and maybe move to websockets if that is stable? +
