Step 2: Step2
now I was afraid at first to post this because of terrorist useing dirty weapons but because of its scale and the velocity of the fuel exiting the aerosol cans I dont think it is possible for it to actualy carry a dangerous payload.
here you will see all the devices I have planned for my orbital rocket
1st I describe the micro controler, a parallax BS2 homework board available in an education kit at Radio Shack for under -$100.
2nd I describe the calculator A TI86 z80 based programable graphing engineering calculator.avalible -wallmart$120 or a pawn shop under -$50.
3rd I describe the cellphone,maybe not everyone has one -under$100.
4th I describe the ignition system basicly a old flash cammera I modified into a "shocker" found here on i'ables and a automotive sparkplug
5th I describe the altimeter, accelorometer and FM Transmitter these are daughter boards available through parallax.com for accessories to the microcontroller sometimes used in hobby r/c planes roughly $50each.
6th the parachute trigger will have to be homemade or found for sale.
7th the engine and gas valvebody ,maybe a commercialy avaliable gasvalve from marine R/V propane heat under$200 if not it will need be machined 2-$600 estimated.
8th fuelbase manifolds homemade or machined under $200 estimated.
9th fuel & air must be calculated around $6 per can.
engine actualy came from a memory drawing of an engine I seen in an 1950's encyclopedia
the rest is prety much parts from a bobot kit from parallax,cell phone and a calculator I hobby with writeing programs for.
the can manifold bases and decision on fuels was all my idea.
