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.

Enjoy ;-)

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.
