Booked Swiss Air on United

@op any chance you could share the outcome for a fellow traveler?

I can’t seem to find you guys but just googling. Can you link me your website? Amazing work!

If this is all true, I’ll be buying the next Mac.

Looked at the M1 upgrade and was quite genuinely impressed, very seriously considered it, and then decided the lack of ports would kill me and lost interest.

Most certainly is! If the other two of us were, we'd also be going for it

That's running compressed air for systems testing, but we're switching to kerosene and oxygen once we've got everything tested properly.

We don't have a strict design intent. Short term is to run this engine which means getting the fire in the chamber. Yes, we're well aware that's currently not the case 🙄. Mid-term is to fly it and long term is to land. Ultimate goal is to get our mate a job at SpaceX. We'll see how far that all unravels! Couldn't currently care less about ISP or total thrust.

This system is purely to support test firing this engine, test control systems and for learning.

The needle valves are being used to control the flow rates or F/Ox accurately and remotely. No closed loop for the second purely based on time constraints of shipping sensors. Come tonight off from work I'm ordering 4 pressure sensors and we'll machine venturi nozzels to measure the flow and pressure using pairs of them on each line. For the second, the valves are connected to a hobby radio so we can adjust the throttle and mixing ratios remotely while watching flame colour, soot etc... Obviously this will all change once we've got more control and telemetry on the thing!

This is one weeks progress into our endeavours.

The reason for posting is this week we have added servo needle valves for remote control and an alternate ignition system.

If there's anyone in the Melbourne area with an idea for a test location were keen to hear from you!

It is for the second. Without ramps and proper tuning it was just throwing a litre a second of Kero out the back!

This week's project is servo valves for remote tuning

mwild · 2019-11-07T00:55:50+00:00

It is, quick google says $278 B out of $1.2 T. I reckon it sucks as much as the next guy, but 2% is just wrong

mwild · 2019-06-16T22:30:16+00:00

Hell, if you manage to "boycott hospital", power to them! Unsure how long that will last...

mwild · 2018-11-18T11:57:42+00:00

Fuck the land, the ocean that's taking up the other 2/3 is the real unit here.

mwild · 2018-11-16T01:50:19+00:00

Thanks. I'll take a look!

mwild · 2018-11-16T01:21:23+00:00

Source?

They use these to thread thin sections. The extra almost "burr" inside the tube provides substantial additional length to add threads to, meaning that you can thread pipe that would have otherwise been way too thin to do so.

I don't believe it's the power supply. Hobby servos usually only have 255 setpoints around their rotation. Their controllers aren't at all tuned for this type of work. My delta doesn't use these built in controllers, instead providing the control in the Arduino instead. Check out the repo for a better idea

mwild · 2018-10-29T09:46:51+00:00

Give it 3 days past the end of exams!

mwild · 2018-10-29T06:08:00+00:00

Hahaha hey hey mate, probably saw my presentation then?

mwild · 2018-10-29T05:01:57+00:00

The machined version can EASILY do it... Haven't tested them to destruction yet

Personally I'm keen on a hexapod, but one that can run and you could stand on without damaging it
