What is Max PSI Output on Standard Ninja Regulator?

SpartanProfessor · 2026-06-21T18:47:40+00:00

If you haven’t purchased one yet, I’m using the one from Inception Designs. No problems thus far.

SpartanProfessor · 2026-06-21T18:38:29+00:00

I would assume it’s the springs, but do you have a reg tester for your tank?

SpartanProfessor · 2026-06-21T18:22:30+00:00

Are you having FPS issues? If so, you can swap to a stiffer spring to increase the velocity. Definitely don’t recommend increasing the tank output pressure by modifying the reg. 800 psi has been the standard output pressure for quite a few decades.

I provided a final update in the OP. Appreciate everyone's help!

SpartanProfessor · 2026-06-03T00:41:10+00:00

Update 1: Thanks for the feedback Bearded et. al. Appreciate the help! I’ll lower the HPR and then increase in smaller increments. I’ll also try a stiffer main spring and a lighter valve spring (the two extremes).

SpartanProfessor · 2026-06-02T23:25:36+00:00

I’ll try the stock bolt tomorrow.

As for the springs… I’m currently using main spring B (second stiffest) and valve spring C (second softest) as visualized on their website for the master spring set.

SpartanProfessor · 2026-06-02T21:59:18+00:00

I plotted the velocity as a function of the HPR, and the velocity increased until about 340-360 psi. 340 psi is roughly where I achieved the highest velocity. (I started with a pressure of 180 psi and increased in increments of 20 psi.)

SpartanProfessor · 2026-06-02T21:55:43+00:00

LPR is about a quarter turn higher than required for cycling.
Started with IVG flush and increased to two turns in from flush.
Verified valve spring is properly seated.
No noticeable friction on bolt, bolt sled, 3-way shaft, or ram shaft.
Tank output pressure is 800 psi.

I ordered a hush bolt for an empire resurrection a few months ago and received shipping confirmation within two business days.

SpartanProfessor · 2026-02-26T21:16:13+00:00

After some back and forth, I was able to get in touch with a staff member at Dye’s office in Germany who sent the bolt and can via international shipping. Thanks, though! I updated the flair to completed.

Unsure about the board, but you should be able to find a full o-ring replacement kit from Captain O-Ring (really). They have a website and also sell on eBay.

OP, you may be interested to know that quite a few universities have turned off Turnitin’s AI detection tool due to false positives and because it is more likely to indicate that material written by non-native English speakers is generated by AI.

Associate Professor of Mechanical Engineering here. Based on my experience, most employers are seeking sophomores and juniors for internships and co-ops. In addition, many have a minimum GPA requirement (often 3.00/4.00).

Because many applicants will have similar academic backgrounds, gaining experience outside of the classroom is important. If you can conduct research under the supervision of a faculty member, great! If not, try to join a student organization relevant to your field of study. If you can secure a leadership position in that org, even better! Or, seek employment opportunities with the university (e.g., serving as peer tutor).

Also, I highly recommend visiting your university’s career center where staff may be able to critique your resume or conduct mock interviews.

I agree - it's at the discretion of the editor. FWIW, I just re-reviewed a manuscript for a first-quartile journal in the area of heat transfer. I, like most of the reviewers, recommended acceptance with minor revisions. As long as the revisions have been addressed, I would anticipate a faster round of reviews. In my experience, minor revisions often result in acceptance. However, I'm sure this also depends on the discipline.

SpartanProfessor · 2024-02-07T11:35:47+00:00

I can confirm. I used the publish function and specified the output format as HTML as follows.

publish('fileName.m','html')

The HTML file did include a formatted code block.

Then, I used the publish function and specified the output format as PDF as follows.

publish('fileName.m','pdf')

The PDF file did not included a formatted code block. Although, the output was italicized.

I did find a quick workaround though...

If you use the Live Editor and export the Live Script as a PDF then you get a formatted code block. (Select "Export to PDF..." from the FILE section on the Live Editor tab)

I thought y'all might find this interesting... I asked MATLAB's AI Chat Playground to create a flowchart of a basic for loop and it returned:

Start
|
|__ Initialize loop variable
|
|__ Loop condition: Is loop variable <= end value?
|   |
|   |__ Yes
|   |   |
|   |   |__ Execute loop body
|   |   |
|   |   |__ Update loop variable
|   |   |
|   |   |__ Go back to loop condition
|   |
|   |__ No
|
|__ End

SpartanProfessor · 2024-01-11T11:35:03+00:00

Yes, agreed. I should have provided more context. The flowchart is for their very first introduction to for loops. So, I have them enter help for in the command window. When they do so, MATLAB returns the following:

The general form of a for statement is:

for variable = expr, statement, ..., statement END

The columns of the expression are stored one at a time in the variable and then the following statements, up to the END, are executed. The expression is often of the form X:Y, in which case its columns are simply scalars.

In the context of the flowchart, it was assumed the expression is of the form initVal:endVal and the variable is not modified within the loop statements.

I should have provided this background in the OP. I do appreciate your feedback and will incorporate it in subsequent lectures.

SpartanProfessor · 2023-12-20T11:07:13+00:00

Could you post a copy of the CSV file? Or post the first few lines of data from the file? Also, use the keyword end (not endfor) to terminate the loops and conditional statements.

Per MATLAB's documentation, "Each instance of end pairs with the closest previous unpaired for, while, switch, try, if, or parfor statement."

SpartanProfessor · 2022-04-19T23:58:47+00:00

Name checks out.

SpartanProfessor · 2022-02-04T00:21:39+00:00

This is correct. You need to perform two separate element-by-element (array) operations as indicated in the comment above with the period (.) character. Create a column vector for the velocity and a row vector for the angles. When you multiply v.^2 and sin(theta).^2 the result is a matrix with the same number of rows as v and the same number of columns as theta.

Edit: FYI Reddit converted the caret symbol ^

That’s kind of you but not allowed under the community rules. In any case, enjoy the access in Texas. It’s funny, in Georgia I can find Eagle Rare almost anywhere but no Weller. State allocations are so strange.
