Its been awhile, but its finally time for a TYOS update. Whats inside? Bug fixes.

Changes to the Camera App

• Fixed error that causes camera to overwrite, delete, and modify incorrect photos, after software is updated. This moves the index.dat file from inside TYOS to /home/pi. Otherwise, whenever you updated TYOS it would think that all your photos were deleted.
• Added missing C library, that caused the camera app to not work at all. Most of you figured out this library was required and found out how to install it, now it is included by default.

Other Fixes

• TYOS now allows calls to be made from countries outside the United States.
• TYOS now allows SMS messages to be sent from countries outside the United States. For some reason TYOS would only accept US based phone numbers. That is now fixed.

How to Update

1. Remove old build of TYOS: sudo rm -rf tyos
2. Download new version: wget https://github.com/spadgenske/TYOS/archive/0.5.6.zip
3. unzip: unzip 0.5.6.zip
4. Rename: mv TYOS-0.5.6 tyos
5. Run: sudo python tyos/src/main.py

Developer Release!

Although I am no longer developing new features @Helmar has been working on his own fork of TYOS. He added a Radio app, that allows the user to listen to FM radio, and a volume settings app that allows the user to change the volume, ring tone, and more all within TYOS. He also made some changes to the time and battery settings to suit his own needs. Its still a little buggy, but if you are looking for some new features please try it out. Note that if you are having trouble I may not be able to help you as I did not write the code.

How To Install

1. Remove standard version of TYOS:

sudo rm -rf /home/pi/tyos

2. Clone new version:

git clone https://github.com/helmarw/tyos

3. Run!

sudo python tyos/src/main.py

System Design

The tytelli is a open source low cost, 3D printable, DIY smartphone used to teach the user about electronics, cellular communication, and computer programming in Python. If the idea is well received tytelli may become a kit.

Licenses

TYOS, the tytelli's core software is under the MIT license.

The CAD design files are under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.

The Adafruit FONA, 3.5in TFT, and Powerboost are under the Creative Commons Attribution, Share-Alike license.

In previous releases of TYOS, the software depended on adafruit-pi-cam, a point and shoot camera project from Adafruit. As you can see in the original demonstration video, the software is slow, pictures are low resolution, and only half of the display is used. All that has changed in the new release.

The new camera app takes full advantage of the entire screen, loads pictures almost instantly, and instead of an endless "Loading..." prompt, a subprocess is created to handle the uploading to Dropbox to reduce waiting times by over half.

A couple days ago I released TYOS 0.4.9, below is a list and some pictures of the new features. Note that some of the features were actually released in TYOS 0.3.2.

New Features

• Error logs. When an error occurs it is stored in tyos/logs/tyos.log
• Audio config file. Switch your audio mode from built in (1) to external (0) in the config filetyos/configure/audio.conf
• Added debug mode to framebuffer.
• More than four apps can be installed. New app list

• Settings app. Delete SMS messages and toggle on and off the headset for phones without built in speaker and microphone.

Along with that, over 15 bugs were squashed with some help from Todd Riesz. Thanks Todd!

How to Update

1. Remove old TYOS build with sudo rm -rf tyos
2. Download new edition with wget https://github.com/spadgenske/tyos/archive/0.4.9.zip
3. Unzip package with unzip 0.4.9
4. Rename with mv TYOS-0.4.9 tyos

I have been working on TYOS over the past week and have fixed many bugs and added a couple of new features.

• Long distance calling now accepted by call app
• Apps automatically exit when phone detects incoming call
• Messages are no longer accidentally considered calls
• Battery percentage properly extracted
• Overall cleanup of code

• New Power app! Instead of instant shutdown when power app is opened, a small menu with options to shutdown, logout, or cancel appears. Logout is great for developers.
• Reception of sms messages! Before you could only send sms messages, but now receiving them is possible thanks to the redesigned messaging app.
• Contacts! Incoming messages will now associate names with numbers. Contacts are handled in the /home/pi/tyos/configure/contacts.conf Create the directory and file and then add a line with this format: Name=number
• Low battery warning! When your phone's battery drops below 30% a warning appears on the main screen.
• --version tag. Use this when running http://main.py to get your version of TYOS. Automatic update checking coming soon

TYOS is still under heavy development so check back soon for updates!
