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.

Thanks, guys, I am not looking to do an automatic horizon, autopilot or anything so complex, just simple, individual instruments.  The existing compass sensor should work fine as is, the accelerometer for turn coordinator and G meter, and I'd need a single pressure sensor for alt/vertical speed and a dual one for airspeed.

After looking more closely at the Tinyshield options, I have a few more thoughts....


  • The edge LED arc shield is interesting, but I'd need some sort of reflector ring to direct the light forward, and for some applications like a compass you really need 360 degrees.  Also, the connector is on the wrong side (female on front vs. male on back) if the LED are to be at the front of the stack.
  • The circle edge LED is also nice and gives 360 degrees but it would also need a reflector ring and odd choice of 21 total LEDs makes it pretty much impossible to have symmetrical indication in all directions.
  • The matrix LED shield is promising, but again the odd choice of a 6x9 matrix makes it more difficult to have symmetrical indications, though I think there are probably enough to get by.

Has anyone messed around with reflector rings to get direct the light from the edge LEDs towards the front?  Also, if anyone has any video of the Tinyshield LED matrix in action I'd love to see it.

Cheers,

Matthew

We did buy some weird circular LED screens for making a programmable automotive gauge, but never had time to move forward with it.  Now that we have more sensor boards I think we need to revisit it.

do they make a Tiny air speed sensor? Last time I saw one, it was pretty big.
