D-Projects: Logan's Run-Deep Sleep Gun Builds - Electronic Version

This thread is to document my build of the fine Logan's Run : Deep Sleep Gun kit from Nicksdad.

For this project, I will be adding a Blaster Core v3 from Plecter Labs to provide the lights and sound effects desired. The BCv3 will be powered by dual 14450 Li-Ion batteries. I have not decided which LED I will use for the barrel flash effects at this time. I am leaning toward a Luxeon or Cree 3-watt Blue running at 700mA. I may also add small LEDs to simulate the TV version power settings. Not sure about that yet.

Here is the kit from Nicksdad...


When I received the kit, I was worried. The box looked like Ace Ventura had gotten ahold of it. It was beat up pretty bad, thanks USPS! But it was well packaged and all parts were bubble wrapped.

So I lay everything out and start thinking about where to place everything.


I wanted to possibly put the batteries in the rear gas chamber but after further observations, the required number of cells will not fit. Short of having a battery custom made, they have to go someplace else. Looking at the hand grips, with some minor modification, both the batteries and BC will fit in this area. With some minor drilling, a recharge port could also be added.

After modifying the hand grips, the only things left to do is solder the connections and program the BC.

Huh Huh! I took a break from studying for my finals this week to do some soldering and whatnot. I finished installing and connecting the speaker and trigger to the Blaster Core. I haven't installed the primary LED yet. The only spare that I have is a yellow luxeon 1-watt. The test video is below.

As for the recharge port, I was thinking the same thing. Put it in the gas chamber, unscrew the cap to recharge. I have a couple of them from previous builds but I need to put a new one inside. I'll order one along with the LED.

OK, back to studying....

Update: Sound files are done and loaded. Video is going up on Vimeo now. Took me a while to get the sound fonts set. I assumed the config file was default and it was throwing me a curve ball by not playing my sound files. Anyhoo, Erv suggested I check it and sure enough, setting were wrong.. Oooppsss. Check that config file!

Next action - Install the LED and paint that puppy.

Del,

Quick question. I am running a 4.5 v pack( 3 AAAs) direct drive to a rebel Green. Would I need a resistor with this? Would it help at all( no sound card yet....) Thanks

I'm not sure which one you have but using the ratings from this one: LXML-PM01-0100

Green (530 nm) Rebel LED
700 mA Recommended Max Current (3)
1000 mA Maximum Rated Drive Current
3.05 Vf Typical Forward Voltage (1)

LED calculator for single LEDs

1000 mA = The wizard recommends a 1.5 Watt capable or greater 1.5 ohm resistor. The color code for 1.5 ohms is brown green gold.

700 mA = The wizard recommends a 2W or greater 2.2 ohm resistor. The color code for 2.2 ohms is red red gold.

A single AAA can output around 1000 mA. In series, the amps remain the same but the voltage is increased. So your probably running at the amp limit of the LED. In this case, the duration that amperage is applied to the LED is short. Adding a resistor will reduce the amperage and give longer life to the LED. If you run it at max amperage for an extended amount of time, it could overheat and fry.

Then again, I could be off my rocker. It's been a while since I did component level repair work so my calculations are ancient. That's why I use the online wizard.
