Firmware source
I can't find the source code for the firmware the adept ships with, only compiled binaries.
Where should I be looking?

Thicker a6?
For about a year and a half, I've been using the leuchturm pocket bullet journal, which is designed to be used in "Portrait" orientation, with a single page number per spread.
It's a great form, only the leuchturm version has only 46 pages, and comes in packs of three.
Since bullet journaling relies pretty heavily on carrying everything with you at once (collections and the index falls apart otherwise), I'm now carrying 4, which means a lot of overhead for binding and covers (I've started tearing the covers off, but I'd prefer not to).
Does anyone know of an a6 notebook with this layout, that comes with more pages?

Actual index size
Would people who have received their index share the size and actual measurement?
We're now being advised to go too large rather than too small, but since the sizing kits aren't accurate either, that's not very helpful. If we know the actual measured size of the ring, and the actual measured size of the sizing kit, we can make educated decisions.

Beans! (Penas blancas)
The Copenhagen OG coffee collective has a lot of boring coffees*, but they almost always have one or two bangers on the shelves. Right now, thats penas blancas. I don't normally go for gesha unless it's washed, but this is just so fun. It's got strong raspberry notes. Just so far out of the ordinary, I love it.
*I get that if they always have coffee in and outside of my taste, they actually just have a great selection

Got a Magikarp from Giovanni, still spent a super radar
Support says they won't do anything, because i "successfully completed" the battle...
Also funny how it was a "thorough investigation", leading tobak automatic reply...

Advice on self-balancing robot project
I'm making a self-balancing bot for fun and learning.
I'm a software developer, with a degree in computer science, so I'm "technical", but I dont know much about electronics or physics. Since the project is turning out to be time consuming, and has a lot of different sub problems to look into, I figured I'd ask for feedback here.
I'm starting out with a simple inverted pendulum on a "cart" riding a fixed track (see picture). The idea is to later extend the problem to controlling an omnidirectional wheel, keeping balance while moving in a plane, not just a line. I was hoping starting with a simplification would help me build intuition.
To measure tilt, I've gotten an MPU 6050, and read blog posts and tutorials on reading gyro scope and accelerometer/IMU data, the plan is to calculate tilt based on angular velocity over time, and feed tilt into a PID controller that controls the motor.
From what I've read, people use kalman filters to handle drift and noise from the gyroscope, but I'd like to understand what I'm doing, not just copy-paste someone elses code, and I've found the explanations lacking. I've started reading the original Kalman paper about kalman filters instead, but decided to post this before I continue.
I see that the mpu6050 is actually supposed to be able to do a lot of this on it's own, using a feature called DMP, but it seems to be undocumented.
Possible paths I see here:
- Continue down the kalman path
- use a different IMU, maybe with more onboard processing?
- Use a simpler method to handle gyro drift, noise, and offset
- skip tilt and feed accelerometer data to the PID directly
Feel free to comment on the overall plan or pendulum-cart test bed or anything else though.
Thanks!
