TERES-I Do It Yourself Open Source Laptop update

We are glad to tell you that we finally have TERES-I released!

It was long way but finally we have laptop which works satisfactory to be released.

What we changed since revision B?

Main board now is with 2GB DDR3 ram and 16GB eMMC Flash memory. We add two new connectors CON3 and CON4 to interface the further FPGA module which will turn TERES-I in oscilloscope and Logic Analyzer.

The debug UART multiplexes now with Headphones, so you can plug serial cable to headphone jack and re-direct Debug console UART to Headphone jack. After you finish debugging you can restore Headphones functionality to this jack. We work on USB-Serial cable with headphone jack for the laptop.

We got new 9500mAh battery which now is in TERES kit.

Another improvement is 5V 3A adapter which allow battery to be charged to full in 3 hours. The adapter has charge indicator and comes with convenient 3 meter cable, so you can lay on your bed while your laptop is connected to power supply.

Please give us some days to update all latest Hardware files on Github.

Work-in-progress User manual and Assembly instructions are here.

The software is let’s say about 90% ready state, but works satisfactory even now.

The laptop comes with pre-installed Ubuntu 16.04 LTS with Mate, Firefox browser, Video player, Open Office, Arduino IDE and IceStorm for FPGA development. We will try to include KiCAD later.

Python libraries to access I2C, SPI, UART, GPIOs will be add when ready.

FPGA module with ADC/DACs/IOs will be ready in the next months, it will be easy to insert inside with the other existing boards.

TERES-I is now for sale.

This project took lot of time and we have long list of registered interest for ordering, bigger than the number of laptops we could build in the first run. We guess many of these registered users are duplicated for black and white version and will take just one, but be prepared that after you order your laptop will not be shipped immediately but in 2-3 weeks (or less) depend on workload and number of orders to be processed. Once/if the first run is sold we will make the laptop out of stock and will work on second run which may take few months to complete, but we will produce this laptop until there is interest for it, so if you do not succeed to order during the first run, do not give up 🙂”
