1  Using Arduino / Audio / Re: Analog modeling synth, smallest in the world? on: June 14, 2014, 01:29:29 am
Do you know any introductions to 'analog modelling' that I could have a look at online ?

Thanks

Duane.
2  Using Arduino / Sensors / Re: how to read PWM signal from RC receiver on: June 13, 2014, 08:27:57 am
Why not just get a 5v Arduino ?

Then start here - http://rcarduino.blogspot.ae/2012/01/how-to-read-rc-receiver-with.html

There are lots of other projects that alter the RC Signals before passing them through like this one
http://rcarduino.blogspot.com/2012/01/traction-control-part-13-we-have.html

or this one

Given the Rolf angle, maybe the keyboard is the right way to go.

Ancient analogue stylus synth. Around christmas they normally have a promotion and sell them for 10 GBP which is reasonable as a donor enclosure, speaker, amp and keyboard/keypad/keystrip ? for an Arduino based synth.

They could sound much better with an Arduino inside.

5  Community / Bar Sport / UNO Still Most Popular ? on: June 11, 2014, 11:32:47 am
Hi,

Been away a while, is the UNO Still the most popular Arduino ?

How are they 32 bit models holding up, are they fragile, discouraging or are they working out well ?

Hi,

Long time since I did anything with an Arduino, but I have the urge to finish a synth I started last December.

I have an existing arduino 5 dollar keyboard synth and also a stylophone with the guts removed.

Question is which to base the new project on ?

This is a quick demo of the filter

and this is a quick demo of the five dollar keyboard, the new project will include the filter, arp etc etc from both projects its just a question of whether more people would build a donor keyboard version or a donor stylophone version ?

Basic version with Arp


Dual oscillator and delay added

Hi,

This post is a better starting point for reading a single channel -

http://rcarduino.blogspot.ae/2012/01/how-to-read-rc-receiver-with.html

For a very simple project thats just going to use one channel and if your not interested in learning how things work you could just use the Arduino pulseIn function.

Hi,

Is the effect from 0:50 in this video the grain decay, if so, its a pretty good filter alternative ?

There is an easy but time consuming work around which is to port the code.

No idea how technical you are but if your upto it you need to find one 8 bit and one 16 bit timer on the Leonardo and then port the existing timer code based on the UNO to use the equivalent Leonardo timers.

How technical are you ?

10  Using Arduino / Motors, Mechanics, and Power / Re: Are motors really water proof? on: February 12, 2014, 01:57:13 pm
A common tunning technique for stock brushed motors in RC Racing is to running them on low power for five minutes submerged in a glass of water. Look up 'water dipping motors' - essentially the water acts like an abrasive to bed the carbon brushes to the commutator and generate a little more power, it may also have a similar effect on the brass bushings that act as bearings in low cost stock motors.

Example here - http://www.rcuniverse.com/forum/rc-drifting-304/5583008-how-water-dip-new-motor-10-step-guide.html

Outside of breaking in a new racing motor which has a short life anyway, its still a bad idea.

11  Using Arduino / Project Guidance / Re: servo signal read on: February 12, 2014, 01:26:38 pm
As others have said, you probably would not want to send an RC Signal from one Arduino to be read by another, but in case you really really wanted to -

http://rcarduino.blogspot.ae/2012/01/how-to-read-rc-receiver-with.html

You could actually generate a servo signal and read it back on the same Arduino without even using a wire, just generate the signal using the standard servo library on the same pin that you want to use to read the signal - probably pin 2, I sometimes do this sort of thing for loop back tests.

Hi,

As I get asked for this and some of the other RCArduino projects on a daily basis, I have uploaded the zipped project folders to google drive.

See here http://rcarduino.blogspot.ae/2014/02/rcarduino-downloads.html

More to follow.

Thanks to all who tried the link, as it seems to be an easy way to share zipped projects I have started uploading some of the rcarduino projects.

http://rcarduino.blogspot.ae/2014/02/rcarduino-downloads.html

More to follow,

Thanks again

I get a page that shows the individual files, but if I select

File/Download,

the dialog box shows IllutronBDEmo0_2.zip which contains all of the files, do you guys see this or some other file in the dialog ?

Thanks

Duane.

The select file/download ?

Thanks
