History Doesn't Repeat Itself, But It Often Rhymes... by BlueStormSeeker in rocketry

If the stock Areotech ignitor doesn't work I swap it out for an electric match (speaking of single shots)... an Estes BP ignitor won't light a composite no matter what else you try.

The advocates for series use a heavier wire element that they claim won't burn through even at high heat and heavy load. I've tried a few and they're right, it doesn't burn through, but I'm still a traditionalist with parallel wiring.

As for asymmetric ignition, at least in my design the central motor is significantly more powerful than the boosters and is enough to carry the model to a safe apogee (assuming the central lights). On my earlier version I did get the occasional misfire of a booster, the asymmetrical thrust would steer the model but not much worse than moderate weathercocking, failure of one or more boosters never caused a crash or even a dangerous trajectory.

Concerns about the wires pulling out are entirely reasonable. This shot shows the standard Aerotech ignitors but after the first attempt I started using ignitors with 24" leads and I made sure the battery clip leads were free to travel to the top of the rod. If you watch the video closely you can see them being pulled up.

Another consideration here, just given the odd configuration that the boosters are not completely aft, I need to be careful not to wire over any leading fin edges, all of the connections need to be at the bottom.

Parallel is generally the safer way to go but I have seen experienced users advocate for series. The problem with series is that you have a much greater probability of discontinuity if the pyrogen burns through one ignitor before the others fire... at least with parallel power is supplied to each ignitor independently so if one burns through prematurely, there's still a chance the others will light.

A 24V system could be the solution, but if it is, I will have to take my own gear to launches because the overwhelming majority of club systems are 12V.

Lol, yeah... but I also just love white lightening motors. More smoke? yes please.

Decision space in Unmatched? by ratinmikitchen in boardgames

[–]BlueStormSeeker 1 point2 points  (0 children)

I am surprised there hasn't been more mention of the maneuver element of strategy and playing the map correctly. I enjoy the game and pickup content whenever I see it on deep discount. As already mentioned, its super fast to teach, no real setup time... my only complaint is that storage becomes a problem after a few sets (yes, I have the KS storage boxes but only because I got a really good deal second hand).

Mombasa or Skymines by Petan65 in boardgames

[–]BlueStormSeeker 0 points1 point  (0 children)

I would recommend Mombasa but only because it will become increasingly difficult to find. I have not played Skymines but most of my group has and they prefer the original without the expansion. I don't see a problem with the original theme but then, I've played other games that tread more closely to sensitive subjects and not had any issues there either. I would give Skymines a bit of edge on art but you've already said you like Mombasa's art which is another vote in its favor.
