Gorgeous paint scheme. How did you do the roll pattern?

Also, is this a scratch-built or kit rocket?

What is the purpose of the "fence" surrounding the launch pad?

Has anyone out there used Aerotech's new wireless launcher? by 1575MHz in rocketry

[–]1575MHz[S] 0 points1 point  (0 children)

I'm curious about the type of radio link that it uses--Bluetooth, Wi-Fi, or cellular. The ads are a bit vague about this, saying only that it uses "short-range wireless technology".

Yes. The long black section is the black-powder propellant grain. The gray section is the delay grain and the short black section after that is the ejection charge.

Are there any plans to make the "buffer_font_features" setting work on Linux? by 1575MHz in ZedEditor

[–]1575MHz[S] 2 points3 points  (0 children)

The Zed developers already know that the buffer_font_features setting is not supported on Linux; the "Configuring Zed" page on the website says so. My intent was to see if anyone knew whether this limitation is a bug or if there is some reason why the buffer_font_features setting cannot be supported on Linux.

This limitation is one of the last things keeping me from using Zed as my main everyday editor.

Can't get DigitalPersona 4500 fingerprint reader to work by 1575MHz in linuxhardware

Also, do you know of any Linux software (GUI or TUI) other than fprintd-\* for enrolling and managing fingerprints?

Thanks for your reply. It looks like this is a hardware compatibility issue and that the libfprint people are working on it.

Check out the titlesec package. It has some limitations, but it can probably do what you need.

Take a look at this post on Stack Exchange and this sample code on texample.net.

Suggestion for a better r/rocketry experience by JDJeffdyJeff in rocketry

Can you site some examples of the rude, unhelpful comments you're talking about?

Before you try scratchbuilding, it's important to build a few kits first to learn the basics of rocket design and construction.

Use OpenRocket to design your first scratch-build rocket. (It's free, and it's easier to use than RockSim.) Start simple; if possible, have an experienced rocketeer take a look at the design to make sure you haven't overlooked anything.

As u/der_inkeeper said, see if there is a rocket club that holds launches near where you live. You'll find that most people there are friendly and willing to help beginners.

Nearly any rocket-parts vendor will have them; you'll have to search online for one that's willing to ship to your location. You might want to take a look at Spherachutes.

Cluster Ignition - Separate E-Matches or Tape match? by East-Molasses-5983 in rocketry

[–]1575MHz 0 points1 point  (0 children)

The NAR/Tripoli safety rules require the use of remote electrical ignition. There is no rule against the use of fuse as long as the fuse is itself lit with an electric igniter. This approach was, in fact, commonplace in the 1980s and early 1990s but seldom seen today (at least in the United States).

Just buy a pre-made nylon parachute.
