Geolocating and animating

Here is another work-in-progress video. We recommend watching it in HD to see the screen clearly.

You can now write Apps that can perform almost any opperatins using HTTP requests (even very complex ones, with custom headers) and geo data (including the real time geo data).

The question marks in street address are there because TCH1 currently does not support printing of UTF8 (non-ASCII) characters.

Get Your Own TCH1 Right Now! (But Wait!)

4dynawas.jpgIf you are one of those "super early adopter" types, there is now a possibility for you to own your own Dynawa TCH1 smart watch!

Before you are blinded with excitement, please read the following paragraphs very carefully!

The Dynawa TCH1 is now considered thoroughly tested and final. This means that all the following hardware is working:

  • Rechargeable battery
  • 8 MB of RAM
  • 160x128 pixels full color display
  • Five buttons
  • Micro speaker
  • Accelerometer
  • Vibrator
  • Light sensor
  • Bluetooth wireless interface
  • Buil-in Micro SD card for storage (not easily replaceable!)
  • Micro USB connector for charging / mass storage mode / debugging

The firmware and software is definitely not finalized and cannot even be considered "beta quality" at this stage. You can try writing applications using the almost-finished-but-undocumented WristOS system (in Lua) and very primitive debugger, or you can be bold, start from scratch and compile everything yourself. It's up to you.

There will be a "Dyno" application available for your smartphone, which communicates with TCH1 using BT protocol and allows the watch to (for example) receive SMS messages and e-mail, accept and reject calls, provide geolocation services and handle HTTP requests. Dyno is currently working almost flawlessly on Android phones. Other phones will follow.

Source code of everything (firmware, WristOS, applications, Dyno client) is available or will shortly be available at You can check it out from the Subversion storage anonymously and you can fork it for whatever means you want but the code currently lacks polish and documentation. Also, we make no specific claims about when the software will be finalized and what features it will provide.

If you understand all of the above and are willing to pay between 500 and 600 Euros for a watch that looks exactly like this (i.e. durable but probably won't get you laid), contact us at The price reflects the fact that the watches are custom-built, not yet mass-produced.

If you have more specific questions, please address them to the relevant discussion group so that everyone may benefit from the answers.

We Have Contact!

This is rather momentous occassion: Our mobile phone now communicated with our Dynawa TCH1 watch and is able to send the Pedobear icon to it...

The sexy one

More detail on this one:

TCH1 sexy

For the conspiracy theorists: Yes, the display is photoshopped on the watch body but it's taken from another real photo of the same TCH1 watch.

Some applications in action

Here are some applications running on Dynawa TCH1.

This should give you some idea about the fundamental TCH1 operating principles, although there is still a substantial work ahead until we have something worth releasing. Specifically, the basic Bluetooth subsystem is almost working, which is necessary for TCH1 to be anything more than a novelty.

Meet The Core Dynawa Team!


As you can see, we take our hobby seriously...

This is our joy after discovering that weird software bug which was plaguing us for three days was in fact hardware-based! (Not a design problem but malfunction in one of the units.)

Application switching and scripting v0.0.0.1

Here is a video of our first attempt at writing some sort of "higher level" bare-bone operating system. It's far from finished but it provides an interesting look at TCH1's speed because large bulk of the OS, including some graphics processing, is written in Lua, an interpreted language.

Sorry about the blurriness, the pronunciation and too many occurences of the word "basically".

You can watch the video in HD to see more details.

The code running on the watch (including the Lua scripts) is already available at You can check it out but in its current state it's definitely not "production quality" code and we definitely don't accept code contributions. Yet!

We have lift-off!

Here is a short clip of firmware booting. Note that the hardware can be easily "punched out" from the larger dev board.

Reset controller is now being finalized. This is an independent piece of hardware which guarantees that the main unit responds to outside events in some sensible way even if the software crashes, decides what should happen if battery is low, prevents "bricking" of the device in case of firmware update gone wrong etc...

Preliminary Reset Controller specs can be viewed and downloaded here (now updated to version 0.3).
