Well im open to ideas turbo, I have an entire schools microelectronics class supply to use lol, our high school teacher as agreed to let me use his supplies. So making several circuits isnt a problem.

Yeah I was going to wire up something similar to that, but the signal strength thing is whats got me stumped.

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?

Hello everyone its been a long time since I posted here, been 2 year member :P. Anyways me and another user on here won a spot to present at a Youth Entrepreneurship challenge and we need to make a demonstration of our product. Basically it needs to be radio controlled device that can control a came...

Yeah they wont jump on their own but set a ground such as a washer or something parallel to the two wires and then it will spark.

Yeah I agree, the same logic should apply if where you live classifies spudguns as firearms or something along those lines. 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.

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.

Only draw back to a bot would be the damn cord lol. The equipment needed to run it off a car battery and not drain it would get heavy...

its a larger one. Its one like on a table saw or furnace. Its 120 volts and its not infront of me at the moment so im unsure of its torque.

So I have a 1700 rpm Utility motor and got no clue what to use it for.... It was from a old science far project that was destroyed long ago. Anyone have any ideas? Ive been thinking about several uses over the last few days.

Ok thanks thats perfect. This is for a math project where I am using external ballistics and Kinetic energy along with the only pneumatic I ever made. I made a simulator on a spreadsheet and doing a live demo and etc.

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.
