I will make a new thread for it with scematics and photo's when all is documented.

I was just thinking about that...

My idea is using multiple LEDs and a 555 timer to make a explosian effect when you shoot. the power to the LEDs can be routed from the IR LED in the turret to recieve power.

And I was planing making a hole in the barrel to let light out.

Please explain your idea.

Only thing needed is a BC547 smd transistor and a 2ma LOW CURRENT led.
The power of the Ir led alone won't do i tried.
The transistor will be triggered by the Ir led.
The transistor and led will be powered by the power cells (2.4v) inside the tank.
I already made it work great but i have to get me a smd transistor because
there's no room for the normal size transistor i used to experiment.
Full explanation will follow.
It's great to pull the trigger... the gun goes off with sound and flare while the tank recoils.
I'm loving this stuff!

meltdown are you planning and kits to sell so us (non-eletric) types can have a great mod?

Meltdown · #19 02-25-2003, 08:59 PM

I'm afraid that these mods are a little to involved to non electric people

Sorry.
You will have to have more than average solder skills to pull these off, especially with smd stuff. The nature of these tanks makes them hard to mod because there's so little room. I'm a tech guy who has a smd solder station, lathe, build my own computer controlled mill and computer controlled telescope. These skills come in very handy for these mods. I feel for the non tech guys over here and wish i could help them. I would if i could. You could all come to holland and visit me for a mod and battle all day

Any further info on the gun flare mod? How did it turn out?

@Meltdown:Where do you live in NL? You Know the Problem I have. Do you think you can help me?

Meltdown · #22 03-27-2003, 04:51 AM

Yo Kadettcab

I live in purmerend. It's 20km above amsterdam. Your problem seems to be of a more serious kind. I will help you ofcoarse if i can. Don't you have any warranty left? If you do it's best to send it in and get it replaced. If not than you can contact me off list using my profile to send me private email.

Alard
I will post the gunflare mod when time permits.
I've been so buisy lately...well you know.

Thanks for the reply, Meltdown. Also am a tech guy. Have many ideas for modifications. Was thinking of using a light pipe for the cannon, with an LED in the turret for the gun flare. The pipes are available here .125" x 1.2". Then the LED could be surface mount or thru hole type.

When I get the chance, I will decode the tank and controller IR signals. This would allow to build a stand-alone decoder, which could make cannon sounds, etc. Structures could then be devised, that would respond to cannon attack.

Napalm Guru,
What sound pod?

Thanks,
Alard

Helix describes it best here.

wow, alard, that woul be awsome to have houses, and bunkers that responded with the tanks! it would also be cool if you could make a buker that randomly fired. It would take combat to a new level!

Still interested in how you did your gun flare mod, Meltdown. In particular, where did you put the LED and how did you wire the transistor?

I'm thinking of fabricating a new barrel from 3/32" or 1/8" styrene tube. Then using 1/16" or 3/32" acrylic rod as a core. The acrylic rod is available in clear, flourescent red, orange and green. The LED would be mounted inside the turret, the acrylic rod would conduct the light flashes through the barrel.

Haven't tried any of this yet. Need to do some experimenting.

After the gun flare mod is completed, will try to decode the infrared signals from the transmitter and the tank cannon. Hope to use that for external sound generation.

Sorry for the late reply Alard!
I'm on tour with my band right now so i'm not at home.
But i've got my powerbook mac with me :-)
I will be back this weekend. Then i shall post the info next week. Also looking forward to the Ir decoding. Should be awesome. Later.

How about...small bore hole in barrel...fibre optic passed through...small led connected in some way to signal from fire/recoil connector on tank pcb...does this sound like sense?

Meltdown · #29 07-14-2003, 07:53 PM

Yeah, that's the way i did it. I used a (very cheap) nylon E string for acoustic guitar as a fiber. This gives the best result. Much better than fishing wire due to the purety of the guitar string. Problem is that the electronics on the pcb won't allow you to drive another led. It will fry your pcb!!. I had to use a little cell and smd transistor to power the super strong white led i used.

curious to see the details of this mod, what became of this thread....
