What ive been working on…
See that orange thing attached to the balloon, thats a vent.
The idea is to use it to vent out helium from the balloon in order to reduce the ascent rate and eventually float! How does it work? See thread below 👇

Turning it around to test the gyro and the accelerometer

Great job addressing this ily
Youre right that we shouldn’t resort to violence and death threats
I do disagree with the ignoring part
I think we should reach out and try to have a conversation and address the questions he has. I’ve tried doing that but haven’t succeeded yet. It just may be that he hasnt had a fruitful conversation discussing islam and what concerns he has off the religion.

Doing venting in “cycles”
I implemented triggers for this cycle to start and stop.
The open command starts it and the close stops it
The idea is to start the cycle at the altitude we want it to start and then let it vent. Open and close delays (time when the vent stays in that state) are now customizable (5s and 10s respectively in the vid below). Close command stops the cycle and we can start another cycle with the open command again
Were launching on 11/24 and the idea is to do controlled slow venting to gather data to calculate constants for a potential PID control we’re developing for complete autonomy.
The goal for the upcoming launch is to slowly reduce speed in two stages to ~0 m/s at 97000 feet and float!
Questions are welcomed
Wish us luck 🫡

i built something
wrote this in C, compiled to WebAssembly, and hosted on vercel.

made a game in zig, will make it so u can play it soon. i will recreate it and add more functionality in C. want to compare both languages

Currently we send email commands, four commands in total
Open
Close
Idle
Cutdown!
Open cause the flap to open and helium starts to exit
Close closes the flap sealing the balloon
Idle is like a refresh command in case used for safety (funny story at the end of the thread)
Cutdown cause 4 nichrome loops to heat up and cut a string that cuts of the balloon from the vent. Thats how we come back to the ground.
How do we send commands? 👇

Presenting the MSP-EXP430
Our microprocessor
This guy only handles the open and close command. Iridium when received open/close it send a signal to this guy (possible because they both have an xbee on them that allows them to communicate) this is just 0/1
The rest happens here
180 lines of C
Open causes the vent to open using a servo
Close, closes it
We observe the balloons speed, the altitude and make decisions on when we want to open and when we want to close in order to slow it down eventually getting a float
Theres a lot of latency and huge room for error
We want to make it autonomous
We want the controller to use pressure and speed readings to decide when to and how long to open and close.
We’re iterating towards it and heres the first iteration 👇

Ive been trying to autoclose it after a given period of time
And it does it!
First time working with interrupts in C
One step closer to complete autonomy

Thanks for the idea @ZachWarunek
Respective emails are now just one click away
Another thing ill build on this is a table to show us timestamps for when each command is sent, really helpful for when we make a timeline for our launch
This was fun
Will build more on it
X is amazing

Btw i do all this aside from having a 60 hour work week
You can just do things especially when you care
WEEKLY UPDATE 🧵
Sunday was launch day so a lot happened over the week, this is my progress till the launch
Will make a separate post for launch day
Assembled a new vent, the old vent has gone extreme tests 😂. Had a problem with getting the seal tight (see the difference between the 2nd and 3rd photo). Tried to get the servo to move beyond a point but it wouldnt (can someone explain why servos dont have 360 degree movement maybe some do and its just the one im using that doesnt). Got the seal tight and even better than before because now I have the servo pulling more on the flap to resist any pressure or winds that may cause the seal to open, its not pulling a lot because then we would run out of battery faster

13 hours since the announcement. Been waiting for them to release this for a while now. Just got done with the documentation & testing different configs. This is just amazing! Excited to share what I am building with this.... @AlanCowen @hume_ai

I do have premium not premium +
I built this cos i wanted to work with software that controls systems and learn hardware along the way

We have four files with names ending with 3 digit binary combinations
Each correspond to their respective commands
We send an email to a satellite service we us with the file for the command we want to execute attached, it gets sent to this guys
The iridum
Our middleman
Receives the file, has an XBEE on it which decodes the binary combination and calls the respective command
Again this is the middleman
So who does the execution? 👇

Picked the CLUE for a datalogger im making and wanted to explore it
What better way than to implement an arcade game

What are u eating?
Cut carbs and sugars as much as u can. Stay hungry for most of the day.
Sunlight in the morning as soon as u wake up.
Will have a huge effect

You should write out your thoughts its an amazing experience.
Writing is a much effective way to explore your thought process at a deeper level. If you think you are a great thinker you would be an even better one if you write those thoughts out
Write my friends
if you extrapolate logic to decisions you make (particularly those where logic <<< emotion). How does the result turn out better or worse?
Hmmm
It could be argued that taking an emotional take is logical too because it fits the scenario you’re looking at. So dealing with a situation on an emotional foundation cannot be labelled as irrational which a lot of people tend to think it is, provided it is what best addresses the problem.
Resolving conflict is a good metric to judge rationality, is your decision resolving conflict or is it, well, “coping”?

U should get one because the length of time youve had a drivers license contributes to stuff like insurance
Get one and push driving a car?

rewriting this in C tomorrow, need to put it on the resume but recruiters wont know what zig is
It will be available to play on web so you can play too, maybe ill do a tpot ranking
made a game in zig, will make it so u can play it soon. i will recreate it and add more functionality in C. want to compare both languages

not as amazing as yours but was an amazing learning experience
~800 line of C
try it out!
