I'm making an air cannon and I'm trying to make it automatic. How do I make the timing circuit?

I don't have all the details worked out but it should look like: http://i123.photobucket.com/albums/o290/Strid3r34/EggCannon.pngI just need to know how to make a timing circuit so that the bolt reloads (the servo should retract then detract), and then the solenoid valve is switched on for a split second (so as not to waste the air) and then reloaded again. I need it do this as long as the trigger is held down. I have no idea how to make this circuit, and I'm totally new to this so please explain in detail. pictures would help a lot.?

Underwater Jetpack Project. [HELP NEEDED]

Im planning on making an underwater jetpack something like this. However I'm a bit to dumb to figure out all the ESC and electronic components of brush-less motor systems.   Im also limited because this is a school project and in order to be reimbursed the materials need to come from amazon.  I will be using it in a chlorinated pool for demonstration but salt water resistance would be nice.  My requirements are as follows:  1.  Propeller must be covered as I may do another project after this one that requires fingers (im thinking 6in diameter pvc pipe with chicken wire or a metal grill over the ends) 2. Modifiable for different circumstances.  (I already cut up an old backpack and screwed a plywood board to it for mounting the propellers and  batteries, however I may decide to go with hand or foot mounting instead.   3. A trigger operable switch. (Cordless drill style although I don't care that much about speed control.   I'm planning this project to be for a senior year high school project (next year) so I have plenty of time. Do you guys think something like this would work for the propellers?  Their for air so I would expect significantly reduced performance in water.  However if they are to high rpm/low torque to spin properly in water perhaps I could keep the enclosure and switch out the motors for higher torque ones.

Could an O2 sensor from an automobile be used inside the combustion chamber of a potato gun?

So I was shooting my potato gun after talking about car repair today, when I got the idea. Could an O2 sensor from an automobile be used inside the combustion chamber of a potato gun to achieve optimal fuel/air ratio? Finding the chemistry of the aerosol fuel would be difficult, and I wouldn't know where to start with the computer stuff, but could it be done? If so, has anyone done it? I searched instructables and no one has even mentioned it. I found on a mazda forum that a wideband O2 sensor may detect the air/fuel ration when using propane, but what about aerosol? Propane in a plastic gun is just begging for injury. I use Right Guard sport deodorant (Without antiperspirant) as the fuel, I think it works the best. The primary ingredient is Denatured Alcohol.

It's just a thought...

Calling all Potato Gun Aficionados and wanna be Combustion Scientists

This is message to anyone who enjoys hearing the sound of forced combustion, or better yet, the loud crack of a potato gun being fired. My co-conspirator and I are in need of some mathematic assistance. Ideally we are looking for a “magic” formula concerning barrel length to blast chamber ratio for optimal performance. The ideal fuel would be propane or butane. We have been using a 4” by 33” blast chamber coupled with a 3” by 44” barrel. So far, we have had significant success with this combination, but are curious if there is a better ratio to use. With our current specs, we are able to shoot a 3 – 4 lb. ball of plaster over 250 yards (this is the carry distance, not the total distance traveled) at a 47 degree angle. If anyone out there knows a formula or has advice on Blast Chamber to Barrel ratios we are greatly interested to hear what you have to say.

Airsoft Tension/Compression Mortar

I've been looking for a way to make an airsoft mortar which uses either tension (by way of wrist rocket or similar bands) or compression (by way of a spring). I'm thinking it'd be similar to the trip mine here:https://www.instructables.com/id/Build-an-Airsoft-Trip-Mine/If anybody could give me ideas or post an instructable, that would be great. I don't want to use air compressors or light anything on fire, because it's just not practical mid game (that would also be just a manipulation of a potato gun). I also think compression or tension could be a lot safer if done properly. Any ideas on making shells to hold airsoft bb's and properly disperse them when fired would be great too.P.S. I'm totally willing to offer my input on the situation if somebody else wants to collaborate on such an 'ible.

Then bury that part with the potato into the ground. After I guess eventually you get a new rose bush. I was wondering can this actually work? Or is this just bait to get you to read more of their articles?
