My New Toy
Not automotive related but w/e
 Thing's a beast.  i just test fired it an hour or two ago with a paper wad loosely crumpled at a 10ish degree angle...shot it 30 feet. and it was dark so it had a pretty blue and orange flame out of the barle. its set up to perfect ratio's of combustion chamber volume to barle volume. it has 2 sparks for a more efficent burn, i was smart and wired them in series.  me friend and i are going potato launching tomarrow night...ill see if i can get a pic of it in action with the pretty blue flames...

Re: My New Toy
We built one of those as well, and they're lots of fun. Ours had only one spark though.

Re: My New Toy
Wired in series with 2 sparks wont have the same effect as it wired in parallel. If you wanted it more efficent, wire it in parallel.
In series, then 2nd spark isnt going to have the same power as the 1st, maybe half if your lucky. In parallel, they both get the same amount of current. Which means they both spark to the full amount.

Re: My New Toy
wong...in series you get equal spark on both ends, in parallel you get a spark on which ever path has the least resistance
 as this is an extremely high resisance circut.

Re: My New Toy
How about some specs on it???
My friend built one a couple years ago that was about 70 inches tall. We used one of the twist lantern sparkers, it worked a lot better than the grill starters did when we tried them. We could get the 'taters to go about 600 feet or so without much trouble.

Re: My New Toy
35" Barle made of 2" Sch 40 PVC
2" to 4" sch40 PVC reducer 10" of 4" sch40 PVC combustion chamber 4" screw on end cap Epoxy w/ notches cut in the PVC was used as glue and 1" screws at each connection 2" screws where used as the electrods for the sparker $10 sparker from lowes after the end cap and reducer its a little over 4" long so far i havent launched a potato (need to stop by the vegtable stand and pick up some). been playing around with it and so far Hairspray gives the best combustion though i havent tried reight guard deoderant which uses propane as an accelerant instead of butane (butane is the downfall of most other deoderants such as old spice of Axe) and i havent tried straight propane, depending on the velocity it shoots potato's im going to fire it at this wooden box i have with a nail in the potato to see if this is the new line of nail guns...lol i shot a gold ball with paper wadding at the box and put a little dent in it and i used Old Spice body spray which uses butane as an accelerant. im thinking of shortening the barle or even putting a screw on cap and making a "versa barle" system. ill get some distance figures this weekend if possible.

Re: My New Toy
If both sparks have the same resistance, youll be getting an even amount. And even if it was uneven, the resistance in the circuit will be lower then the lowest resistor if I can remember correctly.

Re: My New Toy
You do know there is an off topic section for all non automotive related stuff, right?
