I am guessing that compressor came out of a "Frigidaire air conditioner".

Here is a typical diagram for them.

At the other end of that cable:
The start capacitor is hooked between RED and WHT.
The BLK lead to a 15 Amp 120 V switch. Other side of switch to AC Hot of power cord.
The WHT lead is ...

is there a starting capacitor anywhere??

yep, i have the capacitor that was in the ac. what do you need pics of?

so i was given an old ac window unit :D which had a broken radiator and fan, but when turned on i am able to hear the compressor hum. anyway, long story short i stripped the compressor (and kept the capacitor) and if anyone could tell me how to wire this up it would be nice, from what i have been ...

well i just got this in the mail:

(i think its a 3 way) the ebay description was extremely vague. but when air is blown into the threaded port on the left without the lever pushed it exhausts the air. when it is ...

i am quite sure you guys have said to NEVER use solid explosives for cannons... and airbags use a solid explosive. is this dangerous or did they take the ...

anyone on here live in New York city? I'm going to be there all this week for spring break with some friends from school. any recommended sights (other than the empire state building, stature of liberty, ect.)

Yeah I know of Dunedin (embarrassingly, one of our 'biggest' cities), never been there... I hope your friend likes the cold, university students and drinking :D

Tell him to come up to Auckland where all the fun is :wink:

Where is your friend from anyway?

here,(in the united states) Tennessee ...

MrCrowley, are you familiar with Dunedin, its in new Zealand and a friend of mine is going to be there a while. just curious about it

Very nice :) but without a shut off valve the piston is fighting the air on the upward stroke, it only works with low flow and a heavy flywheel.

It would be extremely easy to make, just a pin on top of the cylinder and a check valve:

Yeah there is like 15 videos of ones like that floating around. I'll be sure to post an update for what I change on it. I see no point in having an electric solenoid valve, so I'm going to use a lever actuated valve and a cam on the output shaft. No electricity, no wires. Also reed swithches ...

lol, you would need one big tank, at least with this design, it is so incredibly inefficient. it went thru an entire 5 gallon tank (the tank was at 120pis i regulated it to 20) in the little time i ran it

i built an air engine out of parts i simply had laying around :D this thing was so easy to make and is quite fun to play with, I've finalized the design since i made the video, and its much more efficient and has a lot higher rpm than it does in this video. i am more than happy to answer any ...

I will send you a link.

could i get the link also? now I'm curious as to what it was

kamikaze drones on the other hand offer something new... amateurs can build FPV RC setups for less than 1000$. I wonder if something developed for the military could cost less than 20 000$ per unit.



$1000 is a ton of money to build a FPV system with, I've built a mini FPV plane for under $200 ...
