How do I add color in GIMP?

I have a sketch that I scanned onto my computer, and I want to color it in GIMP. the only problem is, when I try to select an area to fill with color (using the foreground select tool) whenever I then click on the icon for the paint brush or bucket fill tool, the selected area becomes de-selected (if that makes any sense). I've only recently switch from photoshop to GIMP, so any input and advice is greatly appreciated.

7 Color LED Help

I have recently bought two 7 color blinking LED's from RadioShack and learned how to make them change colors and such. I have figured out that if you put a momentary push button switch (with 4 pins) onto the "switch" pin to ground you can get it to change to a solid color then to the cycling of all colors forever. I have two of them set up in parallel, they both start at the same time but slowly become out of sync. Can anyone recommend anything I can do to keep them in sync? I plan on putting these in my car someday as floor lights and it would be nice to have all the lights change color at the same time and not have to keep pressing the darn button over and over again to reset the LED. Any other tips regarding LED's would be appreciated. I am kind of a noob at this so please try and "dumb it down" so I can understand. I am only just grasping the basics of hobby electronics but am very eager to learn more. Actually, any tips in general that any hobby electronics enthusiast should know would be nice.

what could I use for.....

Hello! For a project that i will transform into an instructable I would need a color with following properties: - Stick to metal - Possible to remove using solvents - Water resistant - possibly sprayable - Protect sprayed material from direct contact with water. (not long term.. half an hour is enough.. ) - NOT heat resistant. if heated the color should be damaged and come off the metal without the use of any solvents. - must be as dark as possible any Idea of what could be used? Thanks!

How to dye ants

I ran across this today and thought it was worth sharing. I hope I can find ants with transparent stomachs to try this with this summer. It would take a lot of ant wrangling, but getting them lined up as a color wheel would be the coolest thing ever (I'm fighting the urge to just photoshop it.) Short story is that a scientist fed ants different color syrup and you can see it through their abdomens, pretty sweet...

How to make a "Timed" LED Color Sequencer ?

I would like a "timed" LED Color Sequencer. So instead of a board that flips between leds or strobes I want it to stay in a color for a couple of minutes. Ex: green for 3mins, then fade to red for 3mins, then fade to blue for 3mins then fade back to green.. Time as 3mins is just a example but must be for a longer period then just a fade and longer then just a couple of sec. It must be driven with small batteries, must be driven on its own so no interference of people as a touchpad to switch/fade.How would one do such a idea, do I need to have a microproc or can I skip that ?

Revolutionary Pen Idea

This morning I had an idea. Last night I was dissassembling a huge bagful of insulin pumps (my cousin is a diabetic and he uses them, cleans them, and gives them to me to take the guts out of them) and in them I keep the springs, casing, and insulin resevoirs... (I ALWAYS throw those horrid needles away; I don't want to get stuck with one) I had an idea looking at the resevoirs... I wanted an ink pen that could write/draw in ANY color ink with the turn of a dial, adjustment of a slide, etc.. anyway, I have about fifty of these resevoir things (they have little pistons in them) and I was curious if there was a way to reach my goal. Should I use red, blue, yellow ink, or should I use magenta, cyan, and yallow? Do I have to make the inks myself, or could I drain them from printer cartriges? Should I use only primary colors, or secondary colors as well?

Led color control w rotary switch?

I am working on a project to rewire an old industry hair dryer into a funky floor lamp. It has a cool panel on the back that would fit some kind of a rotary switch.  I would like to use an existing product or products to emit blue light and yellow light from the bell of the dryer. The rotary switch would allow me to ramp it from the blue leds to the yellow leds with some cross over in the middle. my challenge is that, while I understand basic electrical circuits, I know very little when it gets into the more technical circuits and arduino stuff. I want to learn but this isn't the project for it. does anyone know of an easy way to set this up?  My  thought was a set of blue strips, a set of yellow strips and a rotary controller. But, I don't know what to search for online. thanks!

All it says on the page is that there perfect for working with 12v or something. I tried looking at those colour code calulators but I still couldnt figure it out. I knew someone here must know.

RGB LED Sun and Moon

So, I'm working on this thing, its just an idea right now so I won't delve into it too deep, but I want to use a single RGB LED behind a frosted plexi screen as a Sun and another as a Moon, that will move on a clock motor. Could I get a white with a yellow tinge and a white with a blue tinge with a RGB and a few fixed resistors? I'm just wondering if that would be possible. Would I just set the red and green components to 70% and the blue to 100% for the moon and the red and green at 100% and blue at 70% for the sun? Thanks for the help. I don't have any RGBs so I'm just trying to theorize right now.

Can I put Color-changing multi-color RGB LEDs in series??

I need to run a bunch of slow-changing multicolor off of 12vdc.  The LEDs are each rated 2.5-3.4V 20ma.  I'd like to keep efficiency up by reducing the number of series current-limiting resistors and the voltage across them.  So...  Can you put 3 multi-colored LEDs in series with a current limiting resistor (typ 150 ohms) to run off 12vdc... like you do with standard LEDs?  The datasheet specs a operating voltage range and 20ma current. Or...  Does the current draw (effective resistance) of the LED change as the colors change??... Example: When displaying purple, red & blue are both lit. But for red, only the 1 internal LED is lit. If the current changes and the different LEDs are out of time, it would change the voltage across the different LEDs and the series resistor. (I know you can't run an on-off flashing LED off a higher-than-spec'ed voltage because the current goes between almost 0ma and 20ma, putting nearly the full supply voltage across the LED when it is OFF.) So, can I put them in series successfully?? Also, how accurate is the color-changing timebase?   Will they quickly go out of sync.. assuming the same brand and lot.
