RC Pop Pop (Putt Putt) Boat
- hace 6 años
I have had several requests to do an Radio Controlled Pop Pop boat. This one just uses a coil of copper tube as the boiler that I have scavenged out of a previous boat.\r
Unless you get really clever with some sort of remote controlled burner to change the heat in the boiler you have no control over the speed of the boat. You can only control the steering. \r
\r
The build for the previous boat is here \r
\r
Components\r
-\r
Copper tube 4mm diameter \r
- I think mine was about 12 to 18 inches long, it was just\r
what I had left over from previous boats\r
Plastic milk bottle\r
Tea light - at least 3\r
2 pack epoxy adhesive\r
\r
I have been asked for a link for the copper pipe. It was 2 years ago that I made this project so the original link would be well out of date. I have had another look on eBay and here is a similar item although I urge you to do your own search as prices vary and I am NOT endorsing this product or link \r
The radio control transmitter and receiver listing \r
Last time I bought servos I got 10 on this listing \r
The battery pack is 4 AAA batteries in a holder that came from a small torch that I modified by adding a suitable plug to match the receiver.\r
\r
Tools\r
-\r
Utility knife\r
Scissors\r
Pliers\r
Gas ring\r
Wooden dowel about 5/8\r
\r
In response to comments about how to anneal the copper tube I am adding this link that explains the general annealing process without getting too technical and here is a YouTube video on the subject by George Goehl \r
\r
In response to some of the comments received since I uploaded this video I suggest that if you want some history on Pop Pop boats you look at this Wikipedia link on the subject they have been around since at least 1891 when a patent was filed by a Frenchman named Thomas Piot. \r
\r
HOW DOES IT WORK?\r
Water in the boiler is turned to steam. The steam has a greater volume than the water so it pushes out of the boiler and down the tube. In the tube it cools, condenses and contrs so it is drawn back into the boiler and the process repeats. The ion of the steam pushing into the tube pushes the existing water in the tube out the back and that drives the boat forwards. The steam condensing and contring draws water back into the tube ready for the next push.\r
If your next question is why doesnt the boat oscillate backwards and forwards due to this push-pull effect? try blowing a candle out and then try sucking a candle out and you will see the blow is fairly directional but the suck is not.\r
If you watch the video closely you can see the water moving in the straw.\r

Here is a good video on tweaking the speed of these boats \r
