    LED/wiring thread

    Hey, do you guys have much experience with installing LEDs? I'm not talking about with Perfect Grades that come with the setup. I'm asking if anyone has installed an LED (or two) into a kit "from scratch", using parts they got from Radioshack, etc.
    I'd like to put one LED in my recently-build Hygogg. My friend suggested that I place a battery in the "backpack", and place the contacts for the wire in the slot where the backpack goes. That way, I can effectively turn the eye on and off, as well as replace the battery if need be.

    Thoughts?

    Shouldn't be too hard. You could easily hollow out the chest if needed for room for the wire. If you're only doing one led, you could just get a prewired led.

    Guess I should do a demo or guide to LEDs... been meaning to get around to it.

    I'd first draw a schematic for what you are doing. Even if it's a really simple circuit, sometimes building a schematic gives you more ideas and may make the installation process easier. I am assuming that you have some working knowledge of electrical engineering.

    Most of the time, I'd say 99% of the time if you want to put an LED in something like a gundam kit- you want a DC power supply. The amp drain on the LED is usually fairly high for what it is- and depending on the make and model of LED most operate anywhere from 1.5 volts to 3.0 volts.

    When considering your power source, consider where you are placing it. Me personally I build display bases- so sometimes I may put a box on the outside of the display base for the battery. AA, and even AAA batteries may be impractical in a small HG kit. One solution is to use watch batteries. Shop around and see what you can find. You will need to fabricate two metal leads that tape around the battery (never solder anything to a battery) which connect to wires, which are soldered to your LED.

    You will need to make room for the LED and room possibly for the power source. If you want you can also wire a switch into the circuit which simply opens and closes the circuit. They have button switches (small square black piece) as well as toggle switches. It's all up to you.

    Any power source too big for the voltage rating on the LED will require a resistor to turn the voltage down. You aren't just limited to LEDs either- if you had the technology, the time and the patience you could put servos inside the kit and make it move via radio control, but that is way out of the scope of the topic at hand.

    It all depends where you want to put the battery, what the battery is, the technical specifications for the LED, what type of switch you want, how you construct the battery contacts to the wires and if you want the switch internal or external of the mobile suit.

    Some cutting/drilling may be required. Me I would poke the switch out through the armor (by making a hole) so that I can turn it on and off with ease.

    Let us know

    Haven't built one yet Guess you could call it a theory. I'll test said theory on Sandrock EW then once I get back to that project.

    Kind of misleading.

    If you shop at HLJ you can get a good deal on this set right now:

    http://www.hlj.com/product/BAN908842/Gun

    Of course if you don't have any of those models it isn't so enticing. I bought a set and will use the heads but also see how they work (reverse engineer) when I assemble them. I should then be able to work out my own LED light set up. You could always use the kit and modify it to fit where you'd like. They are pretty cool because they switch on and off when a small magnet is placed on the head. The kit includes the plastic head parts as well as LEDs and switches which you have to assemble yourself.There are a few videos on YouTube that show how to put them together. It doesn't look too bad if you have a bit of tech knowledge.

    Was playing around for a bit today, and figured this picture could be helpful for people. Biggest to smallest, 5mm, 3mm and smd.

    Re: LEDs

    another cool option which i came across on the internet:
    usb cables / connector.
    it supplies 5 volt which i usually more then plenty depending on how many leds you are using.

    Also if you know how to solder:
    chip leds are really tiny and fit easy in tiny spaces.

    one tool which i cannot do without when adding leds:
    the 'electric handi drill' from Tamiya which is great for drilling those small holes to run your wires through.

    Wow, those strobe lighting effects are amazing.
