# What makes this laptop different?
|
|
|
|
The TERES-I laptop is a completely open source hardware and software product.
|
|
You don't even need a purchase to access the design files.
|
|
The CAD files and full source code are available at [GitHub](https://github.com/OLIMEX/DIY-LAPTOP) and anyone can download, modify and use them for their own needs.
|
|
KiCad (the CAD design tool that we used to design the TERES-I hardware) is also completely free and open source.
|
|
|
|
The openness of the product puts incredible power and flexibility in the hands of the user.
|
|
If you want to implement new features, you are free to do so.
|
|
If you need another processor, more power, more memory, a better LCD, you have everything required to tailor this laptop according to your needs.
|
|
If you do not like the Linux distribution, you have access to the sources and can generate any Linux distribution for your taste.
|
|
For systems with the Allwinner A64 processor, the Android SDK can be used as an operating system alternative.
|
|
|
|
The laptop is fully modular, meaning that there are numerous possible ways to expand it.
|
|
For example, the capabilities of the laptop may be enhanced by implementing a Field-Programmable Gate Array (FPGA) so it can function as a digital storage oscilloscope and logic analyzer, thus turning it into a powerful portable laboratory instrument.
|
|
Development of these FPGA expansion modules are currently in progress; you can follow their development on the [OLIMEX web site](https://www.olimex.com).
|
|
|
|
TERES-I is environmentally friendly.
|
|
All components of the TERES-I are available for individual purchase, so you can replace just the broken part if one were to fail.
|
|
This lowers maintenance costs and helps reduce electronic waste.
|
|
The main board may also be upgraded without requiring major changes to the rest of the computing system, vastly reducing cost, waste and time when improved processors become available.
|
|
|
|
There are educational benefits in constructing and using the TERES-I.
|
|
You can assemble it with your children and teach them about electronics or how computers work.
|
|
Children may learn about fundamental computing components, how parts and circuit boards are assembled together, and are able to learn to conduct repairs in case something eventually goes wrong.
|
|
This may also spark their interest in electronics and programming!
