I like rockets and things that fly.

Here's the pinout if you're curious. X+/-, Y+/- are for the TVC servos and the I2C lines are for the LiDAR

[Abhigna Y @abhignayrk]

My flight computer can now connect to an Apple multiple scan display from 1994!

[Abhigna Y @abhignayrk]

Made some DB15 cables to connect the servos and LiDAR to the flight computer. That way, I don't have a mess of wires running along the CF rods

[Abhigna Y @abhignayrk]

It’s coming together

More updates soon……..

@EyalPorat2 tshhhhh

[Abhigna Y @abhignayrk]

Spent a couple of hours trying to debug the GNSS radio on a TFAC board only to realize that a ferrite bead wasn't soldered on one side lol

[Abhigna Y @abhignayrk]

The lander is mostly built. Now comes the hard part - stabilizing the vehicle

[Abhigna Y @abhignayrk]

Motor for the new lander, 1300kV with a 7x3.5" blade. Going to put together a little test stand to measure the thrust

[Abhigna Y @abhignayrk]

Making progress on the new lander. The upper section will be almost unchanged. The lower section has the two brushless motors with 7" props, landing legs, LiDAR and TVC servos

[Abhigna Y @abhignayrk]

I really should've tested the EDF before building the lander. Instead of using a larger EDF, I think I'm going to use a contra-rotating bldc motor setup to avoid the weird gyroscopic effects of the EDF. Working on the CAD for the new motor setup

[Abhigna Y @abhignayrk]

Tested the EDF on the (mostly built) test stand. It turns out the EDF I've chosen is way underspecced for this project, with a peak thrust of 800g

Edited some of the Aeroindia pictures, here they are.

1 - F35
2 - Suryakirans
3 - Su57
4 - F16

[Abhigna Y @abhignayrk]

Saw some cool aircraft at AeroIndia Bangalore today. This was my first time doing aviation photography and it was really fun!

1 - Su30
2 - Suryakirans
3 - Su57
4 - F35

New thrust tube for the EDF. This one acts as a mating point for the cf rods, landing legs and tvc servos.

[Abhigna Y @abhignayrk]

Changing up the CAD for the EDF lander. I'll be using carbon fiber rods + 3D printed parts for structure rather than a big old cardboard tube to save weight.

Pretty early on in the CAD, but I have most of the major components in the design

[Abhigna Y @abhignayrk]

New Project! I'm going to build a thrust-vectored EDF-powered hopper vehicle. The end goal is to land it on chopsticks like Superheavy.

So far I have a basic CAD model of the hopper and I'm working on the air intake and thrust tube for the EDF.

Very hyped about this project!

[Abhigna Y @abhignayrk]

@AwSomBasu Looks sick! Love the layout, this is also a rocket ground control ui right?

[Abhigna Y @abhignayrk]

Working on a new Ground Control UI for the EDF lander.

I'm done with the basic layout, now I have to work on displaying the raw telemetry and the backend stuff

[Abhigna Y @abhignayrk]

@AwSomBasu Yep! I made in python with PyQt5. Here's the code for a previous version if you are interested - https://t.co/pm55FZC9gS

[Abhigna Y @abhignayrk]

Working on a test stand for the EDF Lander project. It's going to be made out of a 2020 aluminum extrusion with a load cell on the bottom to measure EDF thrust and a load cell on one of the "arms" for the jet vane characterization.

[Abhigna Y @abhignayrk]

Chunky 80A ESC for the EDF. Waiting for the LiPo and some other components to arrive before I can finally test the EDF
