Rapid Fire/ Sport Pistol Lights Question

Post by Greg Knutzen »

Is there a size requirement/ aswell as a brightness/lumen for the red/green lights?

What is the size and brightness of the lights used at fort benning?

Not as far as I know.

I have been playing around wtih this a bit myself. Automotive tail lights work well using an 1157 type lamp. 12 volts makes wiring easy and they are bright enough. Anything smaller is marginal. just make the lamp, housing and wiring easy to replace, some of us have bad habits of hitting them!

Here's a sample set-up...

I posed this question some time ago, and I was told that when the electronic targets were in use at the range in Atlanta (it's still amazing that place is gone), they were using 2.25 inch floodlights behind a fesnel lens.

low votls lights

Hey all;

If there is no formal requirement, you might try LED's. You get lots of bright in a small package. 12volt DC is common for them.

On related note- anyone have schematics/part numbers for the timing circuitry? All I need is something that will alternate between 7 seconds and 3 seconds and power a 9 volt LED . . .

LEDs

The Sius Ascor system uses an array of LEDs wired in parallel - shoot a light and you will only take out one or two.

For 'club' use the Sydney range has added a layer of lexan over each light to provide an additional level of protection.

That's not hard to design. Here's a simple circuit using 5 chips that should do what you want. Click on the image to get a larger one. Vcc should be 5v. V+ can be anything up to about 70v. The DS3658 can sink enough current to drive even regular light bulbs.

(But bear in mind that this is just a quick sketch using parts I was able to find quickly. I have not tried to build it.)

Thanks! I'll let you know how it turns out . . . I know fancier range timer systems are available for $$$ but I'm wondering if there would be a niche for low cost, battery operated, portable (and simple) system for individual training . . .

This should be pretty cheap, perhaps $10 or $15 for the chips. I could have gone even cheaper (maybe $5) with a 555 timer and an RC circuit but if you're only going to build one unit and you're already that low, it seemed like the precise timing of a real crystal oscillator was worth having.
