      • may be change frequency back to 865.4 ...? gather some data ...
    • may be not related to lora switch only - as the packets become delay (and thus get repeated often) when notebook (wifi) is on battery power!
      • put all LUDP devices onto same ETH switch (router or switch but not both!)

Uno_Serial_LoRa_Sniffer

Sniffer for general LoRa transmissions - very helpful to diagnose OWPJON TL issues.

See also sniffer-txt.py (or sniffer-gui.py) for general network sniffer - very helpful to diagnose OWPJON LUDP issues.

(OWPJON SWBB sniffer is currently missing - device that reacts to any id - may be use PJON_NOT_ASSIGNED, PJON_BROADCAST, or else)

...

Uno_Dragino_LoRa_GPS_Shield_TTN

Send GPS and Sensor Data from Arduino via LoRa as valid LoRaWAN packet to TTN (TheThingsNetwork).

This allows to setup sensors wherever a TTN LoRa(WAN) Gateway is available: https://www.thethingsnetwork.org/community/.

The data (payload) sent can be stored for 7 days and during this time accessed by RESTful API, see the python script supplied.

https://github.com/sanni/cartreader/issues/16

For PS1 (and PS2?) see the Windows VirtualBox VM and look there for MemcardRex and MemCARDuino - look at the schematic also. They do work out of the box, for more info see:

• MemCARDuino: https://github.com/ShendoXT/memcarduino
• MemcardRex 1.8: http://shendosoft.blogspot.ch/2014/01/memcardrex-18-released.html In order to easily connect the memory card a card edge connector is perfect (e.g. EDAC 395-020-520-202). Use a 3.6V Zener with 220 Ohms to get the 3.6V needed - or just use the 3.3V from Arduino Uno.

Setup

(might make sense to split projects off into separate repos/submodules)

I would like to use features like CI (continous integration) keep a copy/mirror on e.g. github and more.

Maintaining a copy/mirror (more precise: with 2 remotes overloaded origin) on GitHub also allows to use GitLab and GitHub together and by that all the nice featurs on GitHub. See also; https://steveperkins.com/migrating-projects-from-github-to-gitlab/

"Option 2: Overload Origin with Both Remotes (needs one single pull/push only)"; in order to clone and set this repo up use:

$ git clone file://///data/mount/gvfs/smb-share:server=.../01git/sketchbook.git
$ cd sketchbook
$ git remote set-url --add origin https://github.com/drtrigon/sketchbook.git

you can check the settings with:

$ git remote -v
origin  /data/mount/gvfs/smb-share:server=.../01git/sketchbook.git/ (fetch)
origin  /data/mount/gvfs/smb-share:server=.../01git/sketchbook.git/ (push)
origin  https://github.com/drtrigon/sketchbook.git (push)

Enable Travis CI for a Repository (for Arduino)

https://learn.adafruit.com/continuous-integration-arduino-and-you/testing-your-project

Login to Travis-CI using the GitHub account and enable Travis-CI for the given repo.

Add a .travis.yml file to your project, commit, pull/push and enjoy.

A word of caution; the travis run will at the end - if successfull - try to push the results back to this repo.

May be split off some sub-directories like MultiWii (for simpler testing), see also: https://help.github.com/articles/splitting-a-subfolder-out-into-a-new-repository/.

Consider creating a docker for testing and may be upload of the skechtes, using: https://github.com/drtrigon/docker-arduino (see also: https://github.com/tombenke/darduino and https://github.com/suculent/arduino-docker-build)

Enable EDRC.ME for a Repository (for Eagle)

See https://github.com/drtrigon/eagle

Enable CAD View (for Catia)

• https://help.github.com/articles/3d-file-viewer/
• https://blog.github.com/2013-04-09-stl-file-viewing/

Create CAD (.stl) Designs online easily

See https://www.tinkercad.com/

Create PCB Designs online easily

See https://easyeda.com/

Do not use upverter or else as it does not allow to export. EasyEDA supports at least netlist export. Locally use KiCAD or eagle.
