A new Arduino clone * chipKIT Max32™ Arduino-Compatible *

Posted by Jonas on May 13, 2011 at 1:00am
Hi I found a new Arduino clone from : Digilent inc.
Looks verry nice :


Microchip® PIC32MX795F512 processor
80 Mhz 32-bit MIPS
512K Flash, 128K RAM
USB 2.0 OTG controller
10/100 Ethernet MAC
Dual CAN controllers
Provides additional memory and advanced communications peripherals
Compatible with Arduino IDE and libraries
Can also be programmed using Microchip's MPLAB (along with a PICkit 3 or 6-pin header)
Arduino Mega form factor
Compatible with Arduino shields
83 available I/O
User LED

The chipKIT™ Max32™ combines compatibility with the popular Arduino open source hardware prototyping platform with the performance of the Microchip PIC32 microcontroller. The Max32 is the same form factor as the Arduino Mega board and is compatible with standard Arduino shields as well as larger shields for use with the Mega boards. It features a USB serial port interface for connection to the Arduino IDE and can be powered via USB or an external power supply.

The Max32 board takes advantage of the powerful PIC32MX795F512 microcontroller. This microcontroller features a 32-bit MIPS processor core running at 80Mhz, 512K of flash program memory and 128K of SRAM data memory. In addition, the processor provides a USB 2 OTG controller, 10/100 Ethernet MAC and dual CAN controllers that can be accessed via add-on I/O shields.

In addition to operation within the Arduino development environment, the Max32 is fully compatible with the advanced Microchip MPLAB development environment and the PICKit3 in-system programmer/debugger.

Very affordable Advanced Head-Movement-Tracker

Posted by Jonas on April 21, 2010 at 7:32am


Found this very affordable headtracker.


Specifications:

Power: 8V to 12V DC power supply. Some
transmitters, especially those FUTABA ones, can supply power directly by trainer
connector. (ex. T9Z, FF9C). Some transmitters cannot supply power to X-GYRO, for
example 14MZ and 12FG. The simplest solution is to use an extra battery for those RC transmitters. The connector is already included in package.
Size: 25mmX35mm
Weight:20g
Range for measuring: +-90 degree/second rotational speed movement.

Default Setting:
Channels: X axis- channel 7 Y axis-channel 8
Detective range G45 degree

Choice for transmitters;
FUTABA: (FF-7, FF-8, FF-9, T9Z, T12MZ, T14MZ)
Graupner: (MC20, MC24, MX22)
Multiplex transmitter: (Royal Evo, Cockpit SX, mc4000)
JR and other transmitters without programmable channel: (9303, 9X)

Paparazzi autopilot

Posted by Jonas on May 21, 2009 at 12:00pm
Last week I received my Paparazzi Tiny V2.11 autopilot.I have read a lot of this autopilot and what made me really excited is the GCS. I have noticed that you need some knowhow about Linux (for me a blessing I am not a windows enthusiast). I really did not have real problems setting up the system so far. The only thing I am waiting for is the ppm converter for my 2.4 GHz TX/RX system. I still have some doubts about the airframe I like to use my little Cessna plane or change to the easy glider pro.

Yesterday I made my first flight with the new airframe Yes it is the EasyGlider pro.It flies perfectly. I tested the telemetry this also worked fine had good readings of alt and speed etc. Only the sun was reflecting in my screen. (yes I now don't buy a laptop with a glossy screen). I did not fly on auto yesterday that is why i love the GCS I noticed that the IR was wayoff and did not work propperly. Turned out I had the XY sensor in the wrong direction.

All the stuff build in.

Canopy closed placed a nice looking antenna. ( just cosmetic the wire is inside)

First flight on auto pilot!

Posted by Jonas on April 26, 2009 at 7:30am
Oke today was a big day I had my first flight on autopilot. (I did not fly exualy)Here are the setup and results:ardupilot 2.1 with z sensor. plane little cessna (see my pics).First I did a field setup to set up the home position. Pilot Marijn Penninx (he builds really great planes, check out www.scale-jets.com) took off and went to a safe alt. So he switched on the auto mode (RTL) and in one sec or less my plane was upside down. Something I did expect because I have noticed that the ir xy is doing the opposite so he got the plane back on the ground and we turned the fma xy 180 degrees (cable facing foreward). Plane back in the air. Safe Alt an auto (RTL) on, now it's responding as it should be. But it wobbles, the elevator is correcting too much. I have seen a little video on this site and they had the same problem (over correcting).I need to alter the code so the elevation is less extreem. When I hold the plane in my hand and point the nose of the plane a bit down, I get full elevation. Where can I adjust this? And are there more settings I need to adjust to get more stability. I have tried to adjust some trim settings but then the plane started to spin down.Pilot Marijn said to me that he uses not more then 10 % of stick to controll the plane.Today's conclusion:- Need to understand why do I need to place the IR XY backwards (cable facing to the front);- Need to fine tune elevation output on auto.Suggestions and solutions are welcome...ThankxJonas

Two funerals in one weekend :-(

Posted by Jonas on April 13, 2009 at 4:30am
How two Ardupilots died in one weekend.Yes I was so proud. I had a perfect working ardupilot. I was going to attach my just arrived Z sensor.Then Murphy law kicked in. When a friend was over I showed him my ardupilot. and the working.The positive power line of the lipo accu was not perfectly isolated and made contact with the back plane of the ardupilot.Yes it fried it. :-( . No swet I have a spare one). Solderd the headers tested the upload all fine. Now I needed to load the new firmware for the failsave. I dit this before and had some trouble but I managed. Now I really made a mistake. I forgot to power the arduino externally with the esc when I burned the hex and fuses and is not responding any more. So my attiny45 is gone now. So I just logged in the sparkfun site to backorder two new Ardupilots. And some xbee's end some other stuff.

Well today I am verry close finishing my first plane with a autopilot.So it is time for some contribution to this fantastic site.First I like to thank Chris Anderson and Jordi for all the effort they made!!I really like what you have done so far!!!
