Update the old DSO_nano version 1 to a new firmware gives the device a new life. The trigger now is much more stable and useful, also the menu structure is more user friendly. I have to admit I should update the firmware before, but in the last years I didn’t use the Nano much. Anyway following the dfu-util howto I have updated the firmware to the DSO BenF Firmware v3.64. It is not the original one, but It work very well.

I have discovered a powerful and easy command drawtiming to generate simple timing diagram for electronic device. Available in debian/ubuntu, can be installed with apt-get install drawtiming then create a simple text file as drawtiming source code (see drawtiming man’s page for details on the syntax), # Copyright (C) 2013 Enrico Rossi # # This program is free software: you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation, either version 3 of the License, or # (at your option) any later version.

I have completed my first video editing project. The video has been recorded with a gopro camera installed on my elmet this spring in Switzerland. A paragliding fly filmed during a sunny day in Ticino from the Cardada Mnt. (see xcontest for the GPS track.) Video editing done using openshot software under debian GNU/Linux. It has required about 30 hours of work form scratch, meaning I never had used openshot before and keep in mind that editing a 4GB mp4 with a notebook is not easy.

This is just a little tips to demonstrate how to use the python bottle micro framework to render a page template which send a js async request (ajax), get the result in a json form and display it. First create this bottle main file, for example main.py, this will respond onto localhost:8080 as described in the bottle manual. The first route ’localhost:8080/’ will render the template json.tpl file which will see later, the second route ’localhost:8080/getallitems' will send to the browser the json converted dictionary.

In the latest days I’m pushing my efforts to put as many documentation as possible to the sintwind project’s pages. Added a lot mix Italian/English docs. Schematics and details. Usage howto. A lot more need to be done like: schematics and PCB in a more useful format (kicad maybe?) Translate everything in English. Assemble a device and test versions later than 3.3 Stay tuned for more to come…
