I am trying google drive, can anyone test this link for me -

It should download the illutronB code in a zip file.

 As the old timers will know I write, its quite popular with around 1,000 visits per day.

 Whereever possible I have put the tutorial code directly in the blog posts, this is a bit ugly but better than nothing.

 In other cases the projects involve more files or a directory structure that is not practical to put directly into a blog post.

 Is there any way to add the projects to Arduino forum or as downloadable zip files, or would any of the established users (mods ?) be willing to host the code for me so that I can add links in the posts and not have to ask people to contact me through Arduino forum and wait for me to get around to sending them the code ?

Let me know if you can help,

Better still, get one decade counter for less than a dollar and a cheap kids keyboard and build one of these -

Thanks CB,

Nothing to do with this then -

What is this link for ?

Who moderates submissions ?

Whats the outcome of a successful submission ?

It would be very simple to put the auduino code inside the illutron and switch between the two using a push button.

The Auduino does not know or care which pin its output goes to so just use whichever one the illutron uses.

The easiest way to do this would be to have

 If auduino pin is high

And do the same in the isr

 If auduino pin is high
   Auduinoisr // change the output pin to match illutron

This way you have very little code to change, you can even keep the setup function exactly as it is on the illutron, this will work provided you remember to change the auduino isr to use the same pin as illutron

Rushed explanation, getting family ready to go camping, hopefully makes some sense to you ?

Interesting thread with a great quote hidden in the middle -

As for safety, personally I'm more worried about the gaffer tape holding the wings on than the control mechanism!

will keep an eye on this one.

25  Using Arduino / Audio / Re: Arduino UNO Low Pass Filter With Resonance - Update Correct Link on: November 15, 2013, 02:29:41 am

The board in the video is something I use for prototyping, its just an Arduino  UNO, five pots, a linear pot and an LM386 Amplifier circuit, partly held together with hot glue.

LM386 Amp -

The pots control - pitch, LFO Speed, filter cutoff and resonance. I have run the Illutron B and the Auduino on this board.

The filter is very demanding in terms of processing power, but its still fast enough to run the four channel Illutron B so should easily drop into anything else thats out there.

With any luck Moshang will drop it into his groovesizer

Tidying up the code for release this weekend.

Quick demo here -

Will publish the code in a day or two and update this post with the link.

Let me know what you think

Some explanation here -

PM Me your email address and I will send the code, but basically you multiply the output by the ADSR and thats it.

Why not build one of these -

It does everything you want -

Onscreen display of lap number, current lap time and best lap time. store and recall multiple sessions with best lap time shown for each and individual lap time review etc etc.

It also works in car or track side.

The instructions to build it are all on my blog and I can send you the code if you message me with your email address.

There was a bug in mircos which has now been resolved, are you using an older version of the Arduino software ?

30  Using Arduino / Project Guidance / Re: Rc light kit How do I make it so I have a programming mode to cal. help plz read on: July 22, 2013, 12:01:02 am
The code in the link i posted allows you to calibate the channels simply by moving the transmitter through its full range - ie you wiggle the controls and it remembers the min, max and center. If you wantbto change setups you press the programnbutton, wiggle again and it will remember the new set up.

To use vthis all you would need to do is replace the code inside the if mode == RUN partbwith your codevfor the lights.
