I was able to program a cute and simple clock with python and the oled exapnsion module, everything is perfectly fine but I need to flip the screen basycally upside down by 180°. I was not able to find information about this control of the display, did someone knows how I can do that in python ?

Thanks a lot for the support

A Totally Fictitious Take on the Convention Badge of the Future

Recent attendees at the Internet of Things Achievements (IoTA) convention were given a bag of parts that were to be assembled into a functional digital attendee identification (ID) badge. If properly assembled, this badge could be used for displaying a simple greeting along with an alternating display of a QR code. This code contained the “Web” address link for accessing the badge wearers’ unique Web access point that was hidden inside the badge.

Imagine this; every attendee was walking around IoTA sponsoring their own unique Web site that could deliver special information targeted towards other convention goers. Forget the old school “Hello, My Name is...” badge, welcome to the future where every attendee is a walking Web site. Yes, there has been a recent rash of do-it-yourself (DIY) construction/hack badges (https://www.parallax.com/downloads/hackable-electronic-badge) at various conferences, conventions, and events around the world, but the IoTA badge marks the first time that no soldering, PCBs, or code was required for the fabrication of a fully functional convention badge.

Just plug-n-stroll through the aisles, booths, and displays of IoTA.

OK, full disclosure here: the IoTA event is totally bogus and the badge presented in this project is completely fictitious. Nonetheless, the Onion Omega ecosystem of plug-n-design components makes it a trivial exercise to build a lavish “badge” in just a matter of minutes. Furthermore, this badge can house an astonishing array of interactive elements that would stress the soldering skills of any conference attendee for building an equivalent DIY badge. And an incredible fringe benefit: adding an operating system, Web site, and/or sensor suite are all feasible with an Omega2 badge.

If you’d like to try your hand at designing a state-of-the-art convention badge, here’s a quick list of the steps I used for making this fake IoTA badge:

1. Pick your fave Onion Omega2 components: I used the Power Dock 2, Omega2+, OLED Expansion, and 400mAh Lithium Polymer (LiPo) battery.

2. Design and print a 3D frame for holding the components.

3. Setup, update, and configure the Omega2+ with the Onion firmware, OnionOS, and specific Omega2+ OLED repositories (https://github.com/OnionIoT/oledQrCodeGenerator).

4. Using guidance from the code in the Onion repositories, write your own Python program for presenting information on the OLED. Don’t forget to install Python and it’s dependencies on your Omega2+.

5. Create a Web site on the Omega2+ and insert the link to this site inside the QR code.

6. Now strut your stuff knowing full well that no eco-unfriendly soldering techniques were used and no PCBs were harmed in your project.

Enjoy the future.

I have Omega 2+ with Power dock and OLED Expansion.
I am trying to use OLED Display. It works perfect with console. But i am not able use it with Python coding.
I followed this Documentation - https://docs.onion.io/omega2-docs/oled-expansion-python-module.html#oled-py-set-memory-mode
And also tried to run this example - https://github.com/OnionIoT/i2c-exp-driver/blob/master/examples/oled-exp.py
The code did not work.
I am have full Python Installed I2C Module for Python installed and OLED Module for Python also installed.
Can someone help me in what I am missing out here ?

Here is the Python code. I happen to have Python3 installed.

#!/usr/bin/env python

from OmegaExpansion import oledExp
import random
import json

getnum = "answer"+str(random.randint(1,20))
with file('/smb/scripts/magic8ball.json', 'r') as answerfile:
	answer = json.load(answerfile)

oledExp.driverInit()
oledExp.setCursor(0, 0)
oledExp.write("+-------------------+")
oledExp.setCursor(1, 0)
oledExp.write("|Magic 8 Ball Speaks|")
oledExp.setCursor(2, 0)
oledExp.write("+-------------------+")
oledExp.setCursor(4, 0)
oledExp.write(answer[getnum])
oledExp.setCursor(7, 0)
oledExp.write("+-------------------+")

exit()

Here is the .json with the answers.

I bought the Omega2+ on Kickstarter on a whim of "well, that's pretty cool. I wonder if I can make my own wifi garage door opener that will use IFTTT to open the door when I get to my driveway?" And then, $125+ and months later, I get my 2 Omega2+'s, power dock, expansion dock, oled expansion, gps expansion and relay expansion. It was a bit of a struggle getting the first one working - I had to reset it twice back to factory - but now I have on device sitting as a webcam looking out my back window and the other is a carry around to just mess with.

I have been able to get a couple projects going, from showing the GPS info on the OLED to getting the Weather for the current GPS location onto the OLED and one that grabs sun/moon info - also showing it on the OLED. My tinker device has been reset more times than I can count now - usually to me doing some dumb install or changing the wrong file or doing something in the wrong order and being unable to back out the changes.

However, I now have my tinker device set up how I want; Samba Server, FTP Access, Python, 16GB SD Card as the ROOTFS and 1GB Swap file (available at boot!) and the GPS and OLED pretty much stay with it all the time. I picked up an innexpensive 8" Windows 10 tablet I use to interface with it via PuTTY, WinSCP and Samba. Hell, I even changed up the banner and customized that.

I have some more ideas of stuff I want to do with this, and one of them requires another chip and minidock, but alas that will have to wait.

All in all, with the help from this forum, I have been able to get everything I have wanted working, so far. Look forward to more projects and seeing the community grow and more projects from others open up so we can learn more. I hope those who've had issues get them cleared up quickly.

And yes, I will be starting on some different tracks now, working my way up to my wifi garage door opener.
