    Simple shooting gallery toy.

    Hi guys,

    I want to build a little shooting game for my nephew. The idea being that he shoots a light gun at a target and when he hits it, it triggers a little water pump which will shoot up a stream of water.

    I've built a simple resistor ladder with a photoresistor and a trim pot (for fine tuning), which feeds the base of a transistor. If you shine light from a torch on the photoresistor, the base of the transistor hits 0.6v and the transistor turns on. So that bit is perfect.

    BUT, my problem is I didnt fully think through the light gun part of it. I thought that I could get one of those Nintendo light guns and shine light from it on to the photoresistor. After further investigation, I realised that the light guns are actually just photodiode receivers, that receive light from the screen.

    I want a gun with a clicking trigger, that shines light from the barrel on to a small surface area. Does such a thing exist?

    thanks,
    j

    acuracy of that will be a joke,

    i would strip a laser-pointer keyring and build it into the gun body,
    then use photo-diodes with red filters to detect the laser.

    using a laser sorts acuracy, using red with a filter reduces problems with sunlight etc.

      I was thinking of getting one of those laser pointers and trying to find a way of triggering it whenever the trigger of the gun is pulled. There surely must be a toy gun with a laser that comes out when you click a trigger, instead of me having to rig one together myself?

        lasers + kids = legal problems.
        (if your a toy company)

          Lithonia Lighting versus Light of America Compact Fluorescent product quality
          by sam_sam_sam
          I have a Lithonia Lighting 65-Watt Gray Hardwired Compact Fluorescent

          I also have back when Light of America had these light bulbs available for yard lights

          The issue with Light of America was the blast boards had all most certain board failure while bulbs hardly ever fail

          While the Lithonia lighting fixture has all most certain bulb failure

          So I have modified the Lithonia lighting fixture to accept the Light of America light bulb and see how long this will last

          I have only had this light fixture for not more than a year if it...

          Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
          by serious_electron
          Hello Everyone!

          I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.
