I just finished the design of my dual stepper motor coil winder PCB.
It occurred to me it could be the basis of a low cost auto pilot.
Ailerons and elevator. The Mikroe $40 Mini MO has 5 analog to
digital ports  for atmospheric pressure sensor and low cost solid
state gyros.

Even cell phones have solid state gyros sort of:)

It even has a black box option recording altitude and heading using
this free Windows terminal program and a PC or tablet for recording
the data.

All you need to do is learn to program in BASIC.

IMHO  I use the Teensy 3.1 at $17 from OSH Park Programmed in
Coridium BASIC  Free 72 MHz 256K Flash 64K RAM 21 Analog pins  16 Bit
34 Digital pins 12 Timers SPI  I2C CAN

Much of what we do will be compatible with that.

The Mini M4 available from Mouser is a bit more powerful than the
Mini MO with 4 more I/O pins. Same maker. I am switching to that.
Largely pin compatible with the MO.

I was under impression that the Coridium boot loader was not
finished.

How well is it working?

I like the 40 pin dip form factor as it works with any 40 pin
socket.

There has been an explosion in the availability of these controller
chips. All others are dead. No more 16 bit chips.

Hi folkz

Did you know about DIY drones? I use the ardupilot since years for
my FPV-planes as safetybackup.

When you will deploy your own code, take a look on this AHRS with a
9DoF-sensor. https://www.sparkfun.com/products/11055?

Enjoy ;-) Claude


The Mikroe ARM is a lot more powerful than the Arduino Mega and it
is easier to program. The ARM uses BASIC and the Arduino modified C
IMHO C is needlessly cryptic.

We are talking full size airplanes here. Although some of this model
airplane stuff could be adapted.

I am a paragliderpilot...and use the AHRS as input for the
(flight)taktical computer. Found the DIYdrone stuff usefull for doing
my airwork ;-)

But in near future I have to play with the ARM platform: Arduino DUE
with ARM-cortex M3 http://arduino.cc/en/Main/ArduinoBoardDue

Where in Germany do you live?

I was just over there last week going to Embedded World in
Nuremberg. Did you go?

Paul Lamar


I am in Leutenberg, Thuringa. It is about 2 hr in the north from Nurnberg.


Glider-taktics calculator CUMULUS works great on android phones, include
a moving map with airspace warnings.
Cellphones are very cheep but lack robustness, sunlight-readableness and
runtime.

Better take an outdoor-navi like the goPal S3747 under winCE and use the
great LK8000-software.
The S3747 offer a touchscreen, will be programmed in VBS or C# ;-) and
can be used as HID for the miniMO-ECU.

kind regards
Claude

You never see any light aircraft flying around in Germany.
What gives?

In my neck of the woods you always see several per day.
