re: Home built ignition generator unit

you don't need the resistor, and the lead from the condensor is positive, the can's shell should be grounded (usually grounded on car's body through the mounting bracket)

re: Home built ignition generator unit

another easy way to determine if your 555 is oscillating, instead of the light bulb , is to use a small speaker, just attatch one end to your ground, and touch the other to pin 3 on your 555, if the speaker squeals, you are good, then you check your mofset the same way.. this is a super simple and e...

re: Home built ignition generator unit

Don't get frustrated man, you are going through a normal learning experience, everyone who fools with electronics has had similar experiences. hang in there and you will not regret it. If I were you I would just start over from scratch. use poly capacitors rated well above the required voltage, 1 wa...

re: Home built ignition generator unit

Your coil should have a cap, some come with one, I guess some don't, go look at the ignition coil on your car, you'll see a little metal can about 1" long, 1/2" dia. You need to get one of these, I wouldn't suggest using any other kind of cap, but others may work, it should be .5uf.. this will help ...

re: Home built ignition generator unit

Oh yeah, also be sure you attach the .5 uf metal can capacitor (that came with your coil) between the coils primary leads!!!

re: Home built ignition generator unit

I'm guessing it's the capacitor on your 555.......... try replacing it, using a ceramic, or poly cap.. about .01uf.. also I can't see the resistor on pin #3, but make sure it's around 200 ohm, not 100 like some shematics suggest... you might try adding 10k pots to your resistors between pins 8 & 7 &...

What's strapped on atop this engine? The square part looks kind of like a reed bank only too big and rods sticking out on both sides? Control panel of some sort?

HEHEH, POPPIES!! been a long time since I've seen any of those fellows, I remember one year when I was a teenager my grandmother, not knowing any better, grew a rather large plot of several different varieties of poppies.. She was quite pleased with how I helped keep her garden up that year... And s...

re: Curved combustors

Thats great! For right now I'm gonna set my sights on building a few proven runners, but eventually I'll have to try a big chinese corkscrew, or something along those lines. I noticed that the twisty lockwood was the same diameter along the tailpipe length except for the last section. How does this ...

Curved combustors

In regard to a picture posted in another thread of this big lockwood: http://www.pulse-jets.com/phpbb2/download.php?id=3677 Anyone here ever bent up an engine like this? looks awesome, and he has saved several feet of length, the kart actually looks proportioned right instead of the normal 6 feet of...

re: Finally a successful ignition device...

Hey, If anyone needs it, I'll draw up a schematic for a very simple, reliable ignition device about the size of a pack of cigarettes, made from components you can get at the radio shack for under $15 (you can build it for about $5 if you have some scrap electronic crap) you can use a 6, 9, or 12 vol...

re: Today's tidbits

Yeah, MK nice pic.. That's in Germany??? interesting (having never left the southeast USA) it looks remarkably similar to a typical dirt road here in N. Georgia (minus the #@%$& beer cans and crap, I hate rednecks).

re: Metal choice and welding.

I totally agree with you, if shot from a smoothbore gun there would be a pretty random pattern of shots, but it wouldn't be TOO difficult to give the barrel a primitive rifling. I've also seen 'airsoft' guns that apply a backspin to the plastic BB's to help with accuracy. I'm not sure how they work,...

re: good source for beginners sheet steel

Thanks Mike, I'll go find some different steel then! I assumed it would be ok, as the set of plans I was looking at specified .013 stainless.. I definately don't want to build one then watch it destroy itself! I know a few folks in muffler shops, heat & air, and my ex-brother-in-law works at a sheet...

re: a different valve design??

Thanks DynaJetJerry, that shed a little more light on the subject for me, I may still give it a shot one day, at least now I know it can work, possibly work better with some design improvement, maybe an assembly of several smaller, lightweight disks..... My train of thought was that if one could jus...
