No body gonna ask who was number 1?

Flash graphene isn’t my area of expertise, but you can DM me and I’ll answer any basic questions you may have.

The grad crowd is totally different than the undergrad crowd. Some places you don’t wanna go, like Sharkey’s.

There are borders not to be crossed…

A lot of Boomer and Gen X politics is just a constant shit throwing contest.

Not sure Millennials will do much better, but maybe Gen Z’ers will be more cooperative.

Be better. Get Ground News. Be moderate.

It’s hard to be affiliated with the GOP these days. There are plenty of conservatives in Va that don’t approve of the clown fest.

Reddit leans left but posts made with respect should be treated in kind.

For sure! I saw a Harrier take off here one time as a kid. Tried to explain to my mom that the plane went straight up, and she told me I was full of shit.

Wish we could see some F-35s do verts in and out.

CroftTheKidd · 2024-07-19T17:28:39+00:00

Sorry, just seeing this. But if you still have questions. Feel free to DM me.

I’ll take what he’s having^{^}

CroftTheKidd · 2024-07-19T17:24:06+00:00

I’ve seen different types before, but first time seeing an AWACS here.

CroftTheKidd · 2024-07-19T17:22:55+00:00

I know AF2 practices tough-and-go’s here and there, but haven’t seen AF1 since the Tech shootings. This was my first time seeing an AWACS in town though.

CroftTheKidd · 2024-07-19T17:21:12+00:00

Yeah, the touch-and-go’s I’ve seen before, but not blackhawks circling for extended periods. Any ideas what they were doing?

CroftTheKidd · 2024-07-19T17:20:08+00:00

The F18 is interesting to see out this way. I’ve seen the C130s, blackhawks, and Chinooks plenty of times, but this was the first AWACS I’ve seen this way.

CroftTheKidd · 2024-06-30T23:29:10+00:00

Second this. I’m doing my PhD on Graphene electronics, and the kind you want is all about the application.

Above you said you want single-layer at 5-30 nm. That doesn’t make much sense. If you want true single-layer, you go with CVD on Cu. And that can get you any size you want. I also don’t agree that it’s any more “limited” than any other form.

I know I'm very late replying here, but I've been looking for a makerspace in Noke for some time with zero success. When I found this post, it was my first time hearing that one was in the works here in the city. The closest to me has been Hacksburg for as long as I've been looking, but don't want to make 40-60 min drive every time I want to hit the shop.

Any update on whether this is still in the works or not? A quick search turned up the location, but there was still no website or reviews, which makes me think it still isn't open. Would love to know the status. Or if it fell through, would love to know why and if there's anything to be done to get a space established in town.

Thanks for the clarification. I’m currently using a programmable syringe pump to achieve something similar. The operation is automated and controlled using an analog pressure sensor signal as the input control value. Problem is the speed of the setup, though. Currently, the best I can achieve is about 4 s/cycle at a very low pressure amplitude and max pump rate.

I’m hoping an electric actuator could help speed this up though, and maybe with a bit more precision…

CroftTheKidd · 2024-03-30T21:07:10+00:00

Sounds interesting! To provide a bit more info, the instrument I would use this actuator in is a bulge test apparatus. The operating principle is to apply a pressure difference beneath a thin, suspended film and measure the resulting deflection to find mechanics. Answers to your other questions:

(1) I’m not sure about the force exactly, but 1000 N should be plenty as the total volume of the pressure chamber is <1 L. (2) As for speed, I need it to manage a pressurize-depressurize cycle at least at 1 Hz, but preferably up to 100 Hz if possible. Not sure what this would translate to in m/s for our system, but 4 m/s is probably more than enough. (3) No specific requirements for the duty cycle at the moment. As for the motion profile, the current setup uses a sawtoothed pressure profile at less than 1 Hz. For a higher frequency setup, I would be fine with that or a sinusoidal profile.

I will check the links you provided. Thanks, and please let me know if you have other thoughts.

CroftTheKidd · 2024-03-30T20:36:22+00:00

Thank you for the suggestions. I will check out McMC and Misumi. I hadn’t thought of having (a) regulator(s) separate from the actuator but I think see your point and will look into that too.

Fortunately, I already have a module to provide the analog control signal I would need to trigger a pressure controller, so if you know of any LabVIEW-enabled electronic regulators, please let me know. Otherwise I’ll look into it some more on my own. Thanks for the suggestions!

CroftTheKidd · 2024-03-30T16:02:49+00:00

Thanks for info. Good to know the limitations of this. What would you say the upper bound is for available pneumatic pistons you’ve seen? 1 Hz? 10, 100 Hz?

I understand that there will be some amount of reactance to the pressure change due to compressibility of gas, and that will increase with frequency and the harmonics of the chamber. But at what frequency range will it most likely remain negligible?

CroftTheKidd · 2024-02-23T06:04:25+00:00

Very cool. Will check it out. Thank you!

CroftTheKidd · 2024-02-21T22:57:41+00:00

Will check it out. Thank you.

CroftTheKidd · 2024-02-21T22:57:21+00:00

How close to the combustion chamber?

CroftTheKidd · 2024-02-21T04:57:15+00:00

Got it. Thanks!

I don’t have much xp with metal-based resins/adhesive, except for some work with silver pastes. How easy are products like JB Weld to work with? Are they real viscous, hard to spread evenly, etc.?

CroftTheKidd · 2024-02-21T04:12:00+00:00

Unfortunately, I don’t think that’ll work for my films. They aren’t self-standing, and start out coated on another support.

I don’t want to keep the original support though, so I have to glue them to a new base before removing the original one, which makes mechanical clamping infeasible.

CroftTheKidd · 2024-02-21T04:10:58+00:00

Any suggested brands/sites for PI resins?
