I think, that was a good catoed flight!

Dont worry, theres no danger is you use it in fountain formulas.

I went to wiki too and read it. What is ment is, that it will produce NO2 if it is heated alone, without fuels.

The fuels in your fountain will eat up the oxygen and nearly no NO2 will be produced.

If someone modifies an old washing machine, he could build a jar with a large diameter but very short. Lets say 40cm diameter and 10cm length.

The media volume would then be 4 litres - thats big but also effective!

@.:HAMMER:. :

I didnt know that NH4ClO4 is cheap!!

PLease PM me and tell me more - I really want some!

Where I come from its not available at all.

@cooperman435:

thats not really correct.

The jar size is very important! Remember that the media travels some way upwards along the inner jar wall and then fall down again. When the falling media smashes the particles you mill, the potential energy, transformed into kinetic energy, is used.

The higher the media is carried upwards, the more energy will be available. A big jar diameter is what you need therefor.


The media should have 1/3 to 1/2 of the jar volume. The milled substances volume ( called grist? ) should be big enough to fill all the room between the media and some more. You should not see your media any more.


The media size will greatly influence the particle size you can achieve. The bigger you media is, the bigger the final particle size will be. To get the finest possible particles, you can use some big media together with some much smaller media. The small ones will fit into the holes between the bigger ones and the milled substance will be brayed and smashed.



Very simple time circuits can easily be made using the NE555 or NE556 IC. Such circuits are available on the net.

Do you need a speed regulation too? What Type of motor is it?



My BP tended to stick to the walls too when I used damp mixtures. Now I use really dry chemicals only and have no problems. Due to the higher danger the mill does its work outside, far away...


@Asteroid:

Washing machine? Not as bad as it sounds...

One could use motor, electronics (modificated), belt and wheels.
