31  Using Arduino / Project Guidance / Re: Sensing absolute height on: September 15, 2012, 12:50:12 pm
one is to heep a moving platform level with some other reference point

Already being addressed using a 5DOF from spark fun. This will be the short term solution for now still using the rotating laser assembly.

the other requirement to keep something like a mowing deck at a specific height above another surface

This is the one i am really questioning because it would be what is needed to replace the expensive survey unit.

Do you guys think something like this or this would work?

I see some threads on using this to get a height off of a weather balloon or a kite....

What kind of resolution could i expect (assuming i use an external chip to get full resolution form the sensor) using these sensors?

Put them individually as i have. Mine compiles fine and your should too once the IDE can find nunchuck.h

What shield do you have? You just said motor.. some shield allow multiple things depending on how you set them up.

A motor shield is for motors. a servo shield is for servos. They are not the same.

If the servos are a fairly small size you can control one or two of them for testing directly from the arduino pins.

Check out the servo examples in the playground or in the IDE and most of them tell you where to connect everything to get a servo to sweep or whatever function the example is for.

I just went and installed the libraries. Examples compiles fine for me.

In your libraries folder did you leave the libraries in a "VideoGame"ShielLibraries" folder or did you just move the libraries into the folder individually?

what i have is ...\arduino-1.0.1\libraries\Nunchuck
37  Using Arduino / Displays / Re: LCD Backlight Inverter on: September 15, 2012, 09:51:54 am
In looking for a replacement for this i have found a few potential CCFL inverters that output between 275 and 350VAC.

Do you think any of these would work or would it not be worth the attempt to potentially burn out the existing backlight?

go here and go down to contributed libraries and see if you are doing is like this.

Start by posting the error you are actually getting.

HA! Very cool.

I had no idea what to expect when i clicked on this topic.

42  Using Arduino / Displays / LCD Backlight Inverter on: September 14, 2012, 10:57:53 pm
I have scavenged a densitron LCD from another piece of hardware. I also grabbed the LCD ballast from that assembly.

I got it all working good using individual power supplies. Tested good on the display and the backlight.

I attempted to tie them all to my TPM 30105 whicich for some reason was outputting 8Vdc instead of 5vdc. My backlight inverter (DAS5V13) did not like this at all. It worked for a few minutes then went dark.

Before failure i had 5VDC on the input side and 300VAC on the output to the LCD. Now i have 120VAC on the output and no light.

I have been searching for a replacement for the inverter with no luck. My experience with these is limited to the research i did to make this rig work.... My question is, how would i cross reference this to a compatible replacement?

That's not an error. It's an example sketch.

Change the name. It's telling you that you can't have dashes in the folder name.

It may not be in under coma nd lpt right away. Do you see anything saying "unknown device" with a yellow exclamation point that goes away when you unplug your uno?
