LOL, Yes, I figure you would be. Have there been many experimentations at those higher voltages? Personally I would much prefer to put the time in improving the drive system rather than using the hammer approach and just over supplying a $0.50 motor. But thin I guess it really depends on how extreme and how much money you want to throw at a project. The way I see it is that I'm in it for the experience of doing the mod, not necessarily the outcome.
Jeo also wrote:I'd imagine that the hard part would be to figure out the correct timing.
Actually by using the smarts of a Microprocessor we can do things like monitor the motor current so that the micro knows when it's no longer driving the plunger spring. So timing would be purely relative. Instead of having the mechanical linkage to ensure the full firing sequence by holding the trigger on whilst the motor runs through a cycle the micro will detect the trigger and turn the motor on then wait for the current to drop back to a non-loaded value to shut off the motor.

There are heaps of other things that can be done just with a bit of software and minimal electronics. Such as the ability to add a PIR sensor to the front and have the gun auto fire when someone step in front of it (Great for one man ambushes, set the gun up behind a barricade and switch it to auto, then sneak around the side with a Recon and have some fun), or even remote firing with a small keyring remote, adding LED sequences for muzzle flash, Bluetooth data monitoring to a smartphone to monitor the blaster performance, with some sensors in the barrel you could monitor muzzel velocity, and track how consistent it is. I could go on, but I think at the moment I'm just thinking up extravagances that only someone like myself would actually find useful.

Now here's where I show my ignorance, I'm confused I thought the breach was actually quite a good seal? Are you talking about sealing the breach to the rest of the barrel? If you are then I would be interested in finding out how much of a performance increase you get out of that considering that with the tapered insides of the plunger casing you only seem to get a seal in the last third or so of the plunger movement. Even with fixing the plunger seal you may only get half of the air compressed in the plunger tube (though I have been considering finding out of you can get some brass tubing that fits neatly within the plunger tube without reducing it's capacity too much. given the current amount of air volume that I can detect I wouldn't have thought that sealing the breach to the barrel would have increased it's performance by much. Not to mention that the faux barrel is oversized and you certainly wouldn't get a seal around the dart unless you replaced the barrel as well. Not that I'm trying to poke holes!!! I'm just trying to understand this more clearly as it seems like an interesting problem. Is there a thread on this topic that I haven't been able to find?
OzNerfNerd, you have mentioned in other posts about the Stampede that "Set up properly, the Stampede is an awesome blaster."... Is there a ONN Stampede set-up guide around somewhere that I could use to set mine up?
