Yeah I have never made a FM transmitter, although I built an amplifier for one which works great. As for the reciever do you think a simple $1 radio from like a dollar store would suffice on triggering the relay?

Personally I live out in the sticks so I can virtually shoot mine where I please but people in Urban areas don't have the same freedom. But if you take a drive out to the outsk...

I like Rhino 3D, only down side is the limit on the number of times you can save but take a screen shot then crop out everything else. :wink:

These can work, as rna said just scrap the mesh stuff and you should be able to find to leads coming out of it. My friend attempted to use one to shock people, I can say the spark is weak but it would work.

Potato weight

Ok I know that the weight varies on every potato. I dont want to take potatos to school and weigh them in the chem lab at school so does any one know the average weight of a potato about 2 inches around either cut or uncut. If not I will take them to the school.

You could buy a servo made for RC throtle cables to simply pull the blowgun handle downwards. But this option might be pricey if you dont have a radio controller that can handle servos.

Conduit is usually used in electrical applications and is not pressure rated unless otherwise stated on the pipe. If it is not pressure rated I would not recommened using it for a pneumatic, however you should be fine if you use it for a combustion.
