"Blinking Eyes" LED circuit. ?

A timer circuit that'll turn LEDs on and off in an approximation of eyes blinking. Ooooon-off-on-off-oooooon-off-oooooon. So, this coming Halloween, I've got a dozen or twenty of these timers, running pairs of red LEDs, about eye-width apart, that are poked through a piece of cardboard spray painted flat black and set in shadowed areas around the porch. Maybe a couple of sets of them covered with ping-pong ball halves to make the "eyes" bigger.

Can someone here point me to some bacteria that glow when stimulated with IR light, or any kind of radiation? Answered

The reason I need to know is I think it would be a real cheap alternative to conventional night-vision goggles. I have seen projects to that end that employ digital cameras with the IR filters left off the lens, but I am concerned that those projects have a latency that would make it difficult to function in real time. I would also be grateful if someone could inform me of a material that would allow IR radiation to pass through, but block visible light. 100 internets to the provider of thebest answer.

Any tips or tricks to obtain free or buy cheap land in the pacific northwest ?

I'd like to give up the silicon valley and move on my own land somewhere that is suitable for an off the grid cabin/year round home. Ideal land would be suitable for small family sized garden, be near fresh water and not be a total snow pile like in klamath falls in the winter. 2000 feet above sea level or lower would also be ideal for what I'm looking for. But I'm sure others might like to know how other people have gone off the grid without having to save money for 20 years just to get there.

Refinishing hood of early 90's BMW?

My buddy has an early 90's BMW...the model number slips my mind. It's jet black, but for reasons unknown, the front hood's clear coat has faded considerably. I was planning to simply mask everything and use some DuPont Clear Acrylic lacquer that I picked up at an Advanced Auto Parts store nearby; then buff it out later with polishing compound. Am I missing anything? It's completely rust-free, no dents etc. Thanks.

How do I record and play a series of videos in some software-controlled order?

I'd like to create an interactive artwork where people can come up to a camera and record a short video of themselves speaking. At the same time, there will be a series of such videos playing on a nearby display. I should be able to insert the new video at any point in the list of playing videos. The list should also be continuously changeable via software; any programming language will do. Bonus points if I can have basic transitions between the videos.

How to Make an Invisible Trail?

I am trying to make a hidden trail that can only be followed with a black light. This will essentially be done by following a series of "bread crumbs" that are only visible in the UV spectrum. I've had some success with a highlighter; the bark soaks up the ink, making it invisible to the naked eye. It's lasted a few rainy days, but I am not certain it will last for (at least) several months. I was wondering if there is another way to do this, one that is a little more weatherproof.
