Today I took the time to finish up what most people call a CPH - a constant pressure homemade.
This isn't anything new, rather, it's something I should have done a long time ago. I built this water gun in 2004 just to be the first one to do it. It had a lot of problems actually, and still does a bit. Luckily, I've worked most of the bugs out of the CPS system.
For those unfamiliar with this water gun, it uses rubber tubing to duplicate the same CPS system used in the CPS 2000, CPS 2500, CPS 3000, among other water guns. The water gun is easily more powerful than a CPS 2000.
The chamber has been changed so that it is easier to assemble. There are several problems however, mainly involving the fact that an easier to assemble chamber also is easier for the inner layer of tubing to "pop out" of. More changes are definitely in store to remedy that problem. I also believe the clearance between the inner and outer layers of tubing reduces power after my testing. I also did not add the 8 or so layers of bike tube I did two years ago, so power definitely is less this time around.
The PC case has been finalized. A lot of people said this water gun looks more like a manufactured water gun, and now they'll probably say it even more.
We tested the water gun, mainly to see if it worked as well as it did before. Our video work obviously wasn't the best (the tilt is one thing), and we need to increase the resolution. It's the first time we've done this. Better videos will be taken in the future.
The nozzle also was replaced with a pipe nipple, for reasons obvious in this video: http://www.sscentral.org/video/mvi_0093.avi

For all of the people who would like to make one of these, yes, a guide is in the works. These water guns are really easy to build and you get back all the effort in how well it works.
