DIY (Do It Yourself)


Starting up the Configuration Reference Manual for Ultimaker CURA 3D printing Open-Source software 🙂

Why only NEXUS devices are sensible choice for Advanced Android Users and Developers? Because NEXUS device vendors provide source code and device drivers.

This makes is possible to re-compile and re-create any customization of the Android by advanced users and developers. The most popular among them is CyanogenMod based on AOSP (Android Open Source Project).

Why is such customization really necessary? Because Vendors does not keep up with the Android development, their releases are flawed, contains unwanted modifications, quite often development is abandoned just after product release.

I know that Drivers Development is time and money consuming task for Vendors. Still, providing source code for device drivers would make it possible to run alternative and/or customized OS, also prolong device life for second-hand users in poor countries. Vendor sells the device anyway and Users can make fixes and customization. Why this Win-Win scheme is so hard to achieve in reality? Is really enforcing sales with mass garbage so important?

Sony Xperia phones are my favorite. Very good and durable electronics, amazing photo camera, nice utilities on top of standard Google Android OS. I have also always respected Xperia for allowing users to unlock their phones for Open-Source Firmware Customization on this amazing hardware..

Unfortunately, Sony seems to have this habit to make a bad decisions, so amazing hardware is not always followed with a good software. This is why Open-Source Customization is so important. I have already found several nice devices with a really bad firmware. What is more, this corruption seems to spread, and Sony blocks factory firmware restore for an unlocked devices with their official Xperia Companion utility. This means unlocking a device does not only Voids a Warranty, but also silently makes it Impossible to Go Back to a Stock Firmware! This is really bad idea.

Luckily smart people tends to predict and help each other out. Developer team of Sony Mobile released EMMA utility (nice name by the way) that allows you to re-flash mobile that is unlocked in case something goes wrong or you simply want to get back to a stock firmware.

Open-Source Firmware Customization will become a standard, even for large enterprises, with mutual benefit to their customers, because looking at the big picture we are part of the same eco(no)system..

As an exercise, I have just designed (using FreeCAD) and 3D-Printed (using semi-translucent PLA material) a casing for M24LR-DISCOVERY (CR95HF NFC Reader). Let me know if you need one 🙂

My port of OpenOCD has just been committed. Enjoy Open On-Chip-Debugger on FreeBSD! =)
