Devlog 2: Rocket designing

Today, I’ve been searching for more fitting parts.
I also used OpenRocket in order to plan the construction of the rocket and to do flight calculations.

I’ve also learned that parachutes are god damn expensive, which is why I’ll probably make my own from nylon fabric.

How did I find this out?

While plotting the calculations for the rocket, there was a spike in acceleration, since the parachute’s diameter was too small. Therefore I needing a bigger parachute.

Yeah!

Other things I might need to do:

• Shorten the body
• Change the Rocket Motor
• learn how to actually fit the motor in with the rings securely
• learn how to secure the nose cone with the shock cord and the deployment of the parachute

Devlog 1: Rocket

Today, I’ve spent most of my time searching for the right parts for the rocket.
I felt that I needed a lot more research, which I’ll be doing without recording. :/

I plan to install a camera in order to record the flights as well as an IMU to measure how far the rocket went.
Maybe even a Piezo, so that the rocket is easier to locate after it landed.

Do you have any other ideas on what to add?
Maybe any tips? :D

Here is an extract image of the partslist that I am working on rn

Devlog 1, building a Tamagotchi!

Planning a prototype:
Today, I started my project by searching for components for the project.
I needed a screen, a power source, a microcontroller and some buttons.
Yeah, like a basic Tamagotchi, y’know?

So I took some time and searched through Ali and also did a drawing of what I plan the Tamagotchi to look like.

Also, I plan on designing my own PCB for it, if everything works out as soon as my parts arrive :>

Thats it for today :D

DEVLOG #5
READY TO SHIP!!
(Hopefully)

Today I have taken the last steps towards the finish line, I’ve created a GitHub Repo here and also worked on a readme file.
I am really happy about how it turned out.
Aaanndd I also fixed some tiny things regarding my code.
I am so happy, that I could get this done, I cant wait to hold this in my own two hands :DD

DEVLOG #4
HELLO AGAIN! :3
I am coming real close to the finish line!
Today, I assembled the 3D printed Case with some left-over parts I had laying around, just to see how it would fit. And it does look nice, I am really happy with it. :happy
Also, I fixed some things on the 3D Model…..
AND I ALSO WROTE THE CODE FOR THE XIAO SEED!!

So, now I only need to assemble the project and upload it to github. But I think about doing a 3D-Render of it, which would mean a bit more work, thats something for tomorrow tho :P

**DEVLOG #3: **
My work from yesterday actually, but I forgot to post a devlog lol.
I’ve just worked on finishing the casing.
I also 3D printed it in order to see if everything is fitting correctly, but sadly I forgot to add supports, which is why a part of the print failed.
Everything else is okay and functional.

ToDo:

• Coding the MiDi-Controller
• Reprint to see if the screen would fit
• Making a nice looking 3D render (maybe)
• Prep and upload on GitHub
• Ship

If I lock in I can finish it today.
But as all electronics projects are, this means it will take at least another day 😭

DEVLOG #2:
HEYO!
Today I have reworked my Casing for a bit. I finally got the dimensions kinda right.
But now… IT NEEDS MORE PERSONALITY!!
Any ideas on what to add in order to make it look better, except rounding the harsh edges?
Also, the Top-Part with the XIAO SEEED needs some special attention too, as the USB C cutout removed parts of the Top Plate, so now its 0.5mm thin at that part. This means I need something there which could make it a bit thicker.

Any Ideas are highly appreciated!!

So, I created my first ever PCB (Old Screenshot btw, I added the 3D Files for the other parts but I am a too tired to take a new screenshot).
I’ve even worked a bit on the case, but I cant seem to get the Top Part of the case right, as the holes are always a bit off. Any tips?
