What are TCH1's hardware specs?

TCH1 hardware specs are:
  • RISC processor from Atmel with on-board Flash memory and 8 MiB of RAM.
  • Full-color OLED display (160 x 128 pixels)
  • Bluetooth stack
  • MicroSD memory card slot for firmware and data storage
  • Five buttons
  • 3-axis accelerometer
  • Built-in realtime clock
  • Vibration
  • Sound output
  • Rechargeable internal battery
  • Micro USB port used for communication and battery charging

Can you be more specific?

Although there are now actual working prototypes of TCH1, the specs are kept intentionally vague for now because there is still a possibility of last-minute design changes. When the first version of TCH1 becomes available, you will have access to detailed hardware documentation.

About software

Is TCH1's software really open?

All TCH1 software (both bootloader and firmware) will be fully open and downloadable free of charge, including the source code.

What default software will be provided with TCH1 by Dynawa?

We are currently working on WristOS v1 operating system which will enable the users to write applications using scripting language and provide sensible API to TCH1's hardware. The default set of applications will provide the expected TCH1 functionality: Clock, alarms, blutooth communication, notifications, microSD filesystem access etc. Customization of these apps, as well as writing new ones, will be extremely simple.

But it's entirely plausible that someone else will create his own OS for TCH1, although this is much more complex task. All required documentation will be availale free of charge.

How exactly does TCH1 boot process work?

TCH1's internal flash memory contains the bootloader which, after the device is switched on, loads the actual firmware from microSD card and runs it. Alternatively (when pressing the special button combination), the bootloader can switch TCH1 to slave mode in which it can be connected to PC and act as an external storage device. When you mount this device from your PC, you get transparent access to TCH1's microSD directory structure.

Where is the source code?

If you are curious, you can study the source code at http://dynawa.googlecode.com. Not everything is currently there but that's just a matter of time.

About Dynawa

Who are you?

We are a bunch of guys from the Czech Republic who messed with computers since early 1980s (we grew up with Commodore and Sinclair computers) and still mess with them. We came up with TCH1 because we ourselves wanted play with nice piece hardware like this.

What is your business model?

Our business model is "Don't lose too much money on this thing". We don't do this in order to get rich off it and we really don't expect Microsoft or Google to buy us. The Dynawa project is not our source of income.

What does "Dynawa" mean?

Whatever you want it to mean. We are not even sure how to pronounce it.

How can I contact you?

You can send an e-mail to admin@dynawa.org.
