Re: Green Laser pen
In the west, the red lasers are restricted, because they are on guns, and if you see a red dot on yourself, you are going to get shot. The green ones are for aiming telescopes at the stars.<p>In the east, we have red and green lasers. If you believe anyone was arrested for playing with them, throw y...

Re: NiMH cells go dead on shelf too quickly
Take advantage of the "no memory" characteristic and leave them trickle charging on the shelf until you need them. I mean like 20ma up to 1.4 Volts.

Re: LM 3909 near equivalent circuit...
Lead acid cells are 2 volts and it is sufficient to light an LED by wrapping two strips of clean Lead (Pb) in insoluble cloth soaked with citrus, charging it up, and then for safety, maybe, potting it in epoxy. Beware:Chemistry is practically always toxic. Commercial lead+acid cells may be expensive...

Re: Converting VGA to RCA
VGA is totally incompatible with television video.<p>A Simple and obvious converter method from VGA to RCA is a television video camera pointed at an LCD monitor. (LCD doesn't flicker).

Re: LM 3909 near equivalent circuit...
This link has a replacement schematic for the LM3909.<p> http://home.cogeco.ca/~rpaisley4/LM3909.html <p>I put the LED flashers in trees as a child for weird reasons and many of them are still flashing today!<p>The chip had a lot of incredibly obscure uses also, which had nothing to do with LED's an...

Re: Robot Vision (image recognition)
Tennis balls are yellow aren't they? And the background of a tennis court is clay that's either brown, gray, or green. Yellow is a peculiar color of high intensity second only to white.<p>I see a lot of high-tech sequential mousetraps where simpler ones or no sequential mousetrap is needed at all. T...

Re: Ideas For A Sensor
Assuming I was building this and with the "camera" that has only one pixel for one chip, scanned simply like a keyboard... (I think that is good because the game board is not full of wires.)<p>I would probably also program the robotic arm using programming which is used once on the first r...

Re: Forget Hydrogen
In the past we laughed at the idea of a car that could run on water or air. Lets have a look at a car that runs on air:<p>The compressed-air electric hybrid.<p>On the road, windmills power air-compressors, so when your car runs out of potential energy, the weather gives you more for free. And if the...

Re: Caller ID Privacy Manager
At the bottom of a heap somewhere I have a device and SOURCE from 2000, using PIC16C84 and 8220P CID-modem chip, if someone is REALLY interested. <p>My device displayed the CID stream and either prevented ringing or made a buzz if the call was "unidentified", as were all telemarketers that...
