You should be able to build a transformer to get from 24VAC to 15000VAC.  If you need either of those to be DC you will need additional components.  Of course the output current will be less then 1/625th of the input current.  Do you know how much current you need to get out of the power supply?

So, just to help anyone else running Mountain Lion (10.8.5) and a  Nano V3.0 ATmega328  CH340G:
My system:
  Macbook Pro with 10.8.5
My Nano I got off EBay and it's full description is:
 Mini USB Nano V3.0 ATmega328 5V 16M Micro-controller CH340G board For Arduino

So, I was able to get things to work finally.   I first tried the recommended (above) link:

After install (but no reboot) I didn't see the desired files.  I didn't know you had to reboot. :-)  So, I am pretty sure it would've worked.   Regardless, since I didn't know about the reboot, I did a bunch of searching and finally got this driver:
 CH341SER_MAC.ZIP from
and finally had the sense to reboot.  It worked.

Anyway, just wanted to say thanks to you all for posting the ftdichip info and hope this helps others that may have had problems like I did.   I think when I begin to get more serious I will use those and also get the official Arduinos.  But for my budget, this approach has got me started.

Thank you.

That domain name is no longer valid. I did find this using Google.

Not much of a sample but the shortest pulse seems to be about 0.333 mS.   If that pulse represents one bit time it would be about 3000 bits per second.  That's not very close to the common async speeds 2400 and 4800.  Perhaps it uses one of the automotive standards like CAN.

As far as understand, you try to actuate an hydraulic cylinder which has a minimum 30 bars of pressure. So you can't use the valve you linked due to pressure rating. That valve is intended for water purposes. If you want to control a hydraulic cylinder, than you need to use a hydraulic proportional valve for example, parker, vickers, duplomatic, aron, hystar etc. These are hydraulic valve manufacturers and you can find a proper valve with proper flow and pressure ratings. But while choosing a proportional valve, you need to take a careful look for control types of valve. Some of them, as far as i know can be controlled by pwm that means you can adjust the spool position, by doing so, speed of the cylinder. But i am NOT EXACTLY SURE for this. I am trying to control a proportional hydraulic solenoid as well and i will be trying in some weeks. (this is because these valves are too expensive, and i want to go over carefully.).

If i end up with a reasonable solution, i will let you know.

I would be better to use >>8 and &255 instead. If you are using a smart compiler it will convert the /256 to >>8 and %256 to &255 but there is a small risk that the compiler will really generate code for /256 and %256.

Hi bobcousins,

your work is  great :-)

> I propose to create a github repository to contain the code.
I forked a github repo for LPC-arduino here:
But I don't know in detail how to work with github project teams.

has anyone tried to get this kind ofdisplay working.
I have just destroyed a dvd player for the plugs, leds etc and wonder if this unit (mine is similar but not quite the same) could be run from an arduino. To look at the number of pins I would say it needs some form of shift register but can't see one.
Any body got any ideas?

Have you looked at the built-in example File->Examples->SD->Datalogger?
