Motorjet to startTurbojet

G’day All,
it’s been a while but I’m back!
(too many Projects, too little money)

Iv’e been working on a Starter Motor for the Turbo Jet project,
I don’t know weather you can make it out from the pix but it’s a Cox .049 ci
with a puta fan blade attached!
(yes Brad it IS the same motor I used on the model boats we made as teenagers!)

Appearntly people tried using puta fans as ducted fans in the early days but,
found them to be useless cos the crappy plastics they were made of used to
fly apart when exposed to 22,000 + rpm
(I wonder why?)


But thankfully puta fans now are made out of tough ABS plastic,
which should be up to the task!
Some of the better quality fans are actually balanced!
(you can see the dremel marks on some the back of the blades!)

Cox went out of buisness in Feb 2009 but Iv’e found a shop
in Canada that has a warehouse full of motors and parts!
(and he does bulk lots too! I bought 6 piston/conrod/cylnder assys for
less than 30 bucks au, including postage!)

You can still get the parts to make a replica “Black Widdow Venom”
(the originals were only a run of a 1000 and are very rare!)
BTW, FYI, the “Black Widdow Venom’s” were the motors that could pull
22,000 revs!


I have yet to fabricate a bracket to mount the
motor in the “Duct” but as you can see it basicaly
fell together, just drill a few holes in some Stainless Steel tube and Vioal!
A home brew Ducted Fan,
the stainless came from the inside of a “Thermal Cup”
and is quite lightweight and a perfect fit to the Turbo Inlet.
(just dumb luck!)

The motor in the pix is also rare for other reasons,
it is a single transfer port bore which were discontinued early on cos
they only pulled a measly 10,000 to 12,000 to revs!
The more common one comes
with 2 transfer ports and “Slit Exhausts” they pulled from 15,000 to
17,000 revs!
And the Venom’s piston was lightened, polished crankshaft, they had
extra ports and had higher compression
they were capable of 22,000 revs

The Idea is use a drill to start the Cox motor then plug the Cox into
the turbo’s inlet to start the Turbo Jet!
Cool huh?

BTW,
Ducted Fans actually qualify as a Jet by themself and are also known as Cold Jet’s ,
Motor Jets or (my personal favorite) Piston Jets!

cheers, Mick. ‘-))


Lord,
if you can’t make me a better Boy,
don’t worry about it,
I’m having a great time as it is!

Creating A Linux Arduino Development Enviroment

I started playing with my haceduino 2009 and couldn’t get it to upload sketches to my board, I played for a while trying to hit the reset switch at different times but with no luck.

I hooked the board up to a windows machine and had it uploading almost right away so this led me to my Linux machine being at fault. What to do, what to do….

So last night I played with a few different Linux distros to find one that works “right out of the box” so to speak. It had to be a mainstream distro, had to be a clean install and only need packages available from the repos so as not to have to revert to compiling from source.

This guide is to set up a machine from scratch with the latest Ubuntu release 9.10, it should work with kubuntu and xubuntu as well but I offer no warranty as to the sutablity of this guide to your own hardware and setup

INSTALLING ARDUINO IDE FOR THE HACEDUINO 2009 ATmega328 UNDER UBUNTU KARMIC KOALA

Do a fresh install of Ubuntu Karmic Koala 9.10

At the command line perform the following commands to prepare your system for the arduino IDE.
  • sudo apt-get update (Update Package list)
  • sudo apt-get upgrade (Upgrade all installed packages)
  • sudo apt-get remove brltty (Remove as it conflicts when uploading sketches)
  • sudo apt-get install sun-java6-jre avrdude gcc-avr avr-libc ftdi-eeprom (Install dependencies for the Arduino IDE)

Now that the system is ready we will install the Arduino IDE, follow the next set of commands to install the latest IDE from arduino.cc via google code

  • cd ~/ (change to your home directory)
  • wget http://arduino.googlecode.com/files/arduino-0017.tgz (Download IDE from googlecode)
  • tar xzvf arduino-0017.tgz (extract files from the archive)
  • sudo reboot (reboots the machine)

Okay with that all done and your machine rebooted you should be ready to hook up your Haceduino and upload a sketch

  • Plug your Haceduino in to a USB port and wait 10 seconds for it to connect
  • To run the IDE you need to exucute the file ~/arduino-0017/arduino this will launch the IDE
  • Go to tools/board/arduino and select Duemilanove or Nano w/ ATmega328
  • Go to tools/serial port/devttyUSBx (Select the port your board is plugged in to)
  • Load a sketch from the examples choices, the file/digital/blink is a good start to make sure it is working as it doesnt require any additional hardware apart from the haceduino and a USB cable
  • Click on the upload button second icon from the right at the top of the IDE and the sketch should compile and be uploaded to the Haceduino 2009, the red and green serial traffic LEDs should flash for a few seconds
  • You should now have an orange LED blinking on the haceduino that is different to the dit dit dah flash that was all ready on the haceduino.
  • By playing with the values in the sketch you should be able to make it blink faster or slower, why don’t you have a try now.

Well all going well that should be it and you will have a Linux environment that you can program your Haceduino in, congratulations and happy hacking
