Pins A4 and A5 are used by this shield. There are direct wiring points for INT1 & INT2 as well.

Very cool. Sounds similar in some regards to the wifi sensors I have been tinkering with. Linking them to a Pi. I have not attempted the radio transmitters yet. Good luck and let us know how it goes.

Have you tried Codebender ( They have sample code for quad copters. However, I have not seen any directly for Tinyduino. Thus, you will have to make some lib adjustments. I imagine you will also need the 9dof shield for stabilization.

There are examples for it on Codebender. Since it is part of the Tiny Circuits system, it should run off their current processor board with LiPo.

If you are looking to create a motion data logger, it sounds like you have the right idea. You will need a SD card shield. The storage on a TinyDuino is too limited for two weeks worth of data. You would need to set the time/date at the sketch upload point to use for a timestamp. Otherwise, you will need a real time clock shield as well which will draw more current. The TinyDuino would then pull the accelerometer data at the time interval you desire, calculate the current time based on the start time plus number of intervals, and write it to the SD card.

I would use the TinyDuino with LiPo support for the LiPo battery tends to last alot longer than the coin cells.

It sounds like a great little project. If you want to take it a step farther, you could use the 9dof shield and get compass direction and gyro orientation as well which would be cool if you expect the item to be rotated a great deal during application.

Have fun.

The new Tiny Circuit LiPo's for the latest TinyDuino are very small and last a long time. Sounds like a fun, doable project.

This looks like a feasible Tinyduino project. You will need the processor board, the SD card board (for storing images), and a 3rd party camera board. You will also need one of the proto boards to wire the camera to in order to add it to the stack. Time lapse durations could be set in the code or you could expand the project to include the Tinyscreen which has 4 buttons on it. Those you could make to change time settings and start/stop the camera as well as show last image taken.

Have fun!

Sounds like you could cover most of the desired readings with the Tinyduino 9-axis IMU and the Tinyscreen. The Tinyscreen even has four buttons in which you could use to rotate through the display readings. The screen is quite legible in direct and low-lighting. The Tinyduino does have enough processing power for it. I use Tinyduinos for flight and sensor data on my quadcopters. I have it write data to an SD card instead of viewing it real time. However, they have the long range 433 MHz radio shields now. So you could collect the data from one Tinyduino on the aircraft and send it to a separate Tinyduino with display so you can clip the display where ever you desire.

Hi Phil,

That is very strange. I have been using Tiny Duino for around a year now and have used multiple USB boards. I have never had a problem with them. I have had a few issues with uploading sketches. However after a short debug, I found it was a faulty USB cable. What is your stack and set-up?

That is amusing because one of the first things I did upon receiving my Tiny Screen is hold it close to my eye to see how a pair of glasses would look. The answer was completely out of focus and I simply worried I was becoming farsighted.

You can get a variety of optical prisms from Edmund. However to my knowledge, Google Glass does not use a traditional prism. It uses a series of proprietary vacuum deposited coatings between laminates to create its HUD.

The link for Edmund prisms though is:

Let me know how the experimenting goes.

TinyDuino Processors & TinyShields / Re: TinyScreen Joystick Board

This might help. I combined the joystick code from that sketch with TC's Flappy Bird code. This way you can at least use the left stick to fly.

It is fully operational right now. However, I am working on this code with my son to add in a few additional features such as title screen, high score list, and lives (which were not in the original script).

Any updates on shipping orders? Will people receive notification when their's is shipped out?

I had this problem once before. It was in my USB connection. I unplugged the USB shield, replugged it in and made sure it was seated correctly to the microprocessor board, and then I also swapped out my USB cable. Since then, I keep a designated USB cable at my work station and have not had the issue since.

Thanks for the update Ken. I cannot wait!
