Laser Projector (Red, Green, Purple) "Laser 3D Party Light" from Spencer's

[james]

A couple notes on that from my experience getting this set up... I'd recommend wxDev-C++ (Dev-C++ is really old, hasn't been updated in a long time, and IIRC bundles too old of a gcc to compile one of the libraries). Also, when getting the Boost library, I believe it needs to be 1.45 or older. IIRC tried 1.52 at first, and LaserBoy failed to compile, due to a change (in the file system stuff I think) they made in 1.46.

Thanks for pointing that out. I will look into using wxDev-C++!

SD Card update: I ordered one each 1GB and a 4GB Elite Pro card; glad I ordered the 4GB, because it works fine, but the 1GB does NOT. The 1GB even has the same numbers on the label. It does, however, have less space than the stock card:

Stock card:
The type of the file system is FAT32.
Volume Serial Number is 2C8F-7D07
Windows is verifying files and folders...
File and folder verification is complete.
Windows has checked the file system and found no problems.

1,006,616,576 bytes total disk space.
4,096 bytes in 1 folders.
28,438,528 bytes in 62 files.
978,169,856 bytes available on disk.

4,096 bytes in each allocation unit.
245,756 total allocation units on disk.
238,811 allocation units available on disk.

New card:
The type of the file system is FAT32.
Volume Serial Number is 560A-8222
Windows is verifying files and folders...
File and folder verification is complete.
Windows has checked the file system and found no problems.

994,488,320 bytes total disk space.
4,096 bytes in 1 folders.
16,826,368 bytes in 18 files.
977,653,760 bytes available on disk.

4,096 bytes in each allocation unit.
242,795 total allocation units on disk.
238,685 allocation units available on disk.

SO. Not sure what is up with that. If I have time after the holiday I may poke at it some more with some linux-based utilities; this is all under win7 command prompt.

BTW... we had AWESOME FOG here in N VA tonight... took the opportunity to take the little Spencer Gifts Projector out back for some lightweight "beam shows." It was super fun! Blue is nearly invisible, but shows up on camera OK. When I pull the pix off my camera I will come back and post a few. I think they turned out OK.

My favorite shot of the night from this projector... I need one of those Osram PL450s...

Aww man... driving home from work in that fog, I thought that exact same thing (after seeing how cool the police and ambulance lights looked from all the accidents :P )... but by the time I got home from dinner, it was mostly drizzle, and I was afraid to take the projector out in it. Definitely post the pics!

Edit: Nice pic! I wanted to make a vortex, though I don't think I would have had time to make anything cool before losing the fog. I've never really messed with beam shows on it since I use it in my basement (no fog machine or anything).

That's weird about the card... though unless you copy/pasted wrong, they look identical in size (1,006,616,576 Bytes vs. 1,006,616,576 Bytes). BTW, is the 4GB card SDHC, or just SD?

I'm working on getting wxDev-C++ set up on my Win7 laptop. I don't want to mess up my main workstation. I want to figure out how to get it to work on another computer first.

My first attempt has not gotten me to where I can compile with libSDL. I fallowed the instructions and it seems simple enough, but for some reason the compiler can't find SDL.h!

I think I'll try it on yet another computer that is running XP.

I believe I installed SDL through the package manager inside wxDev-C++ (Tools->Package Manager, IIRC).

I did that too!

I think it might be something as stupid as a Windows environment variable for INCLUDE and LIB, even though I defined the paths in the build environment in wxDev-C++.

I'll have another go of it. I just got tired of it yesterday.

Besides that, I want to make sure that both libSDL and Boost are up-to-date. That's the whole point!

UPDATE: Juat tried it again. No luck. I don't get it. I used the built in updater and it even shows the version numbers of both Boost and libSDL that it says it has installed.

But it still cannot find <SDL/SDL.h> !!!

You could always try inside a VM... VirtualBox is free and does a reasonable job of hosting VMs.

Have you verified that the file it says it can't find is actually present on the disk? I've had that happen before. Package gets half installed, or winzip messes up a tarball, or optional packages aren't uncompressed from the install folder... not with that environment specifically, just in general...

I think i will take the text file approach initially. But, the wife says no more laser play until after Christmas. :-( Too much to do to get ready.

[james]

I can go right to the include directory and see the SDL folder with SDL.h sitting right there!

I don't get any errors about Boost, but maybe it just doesn't get that far....

[DogP]

You could check to make sure the directory is in: Tools->Compiler Options->Directories->C++ includes . And since you're doing #include <SDL/SDL.h>, make sure it's including the directory that has the SDL directory, not the SDL directory that has SDL.h .

It could be something goofy w/ Windows 7 too, of course... I've only done it on XP. If you've got Windows 7 Pro (or better) you can download Virtual PC with a fully licensed XP direct from M$ (XP mode I believe it's called).
