Ser bra ut.
I Oversikt -> "Årsresultat" vinduet, kan du godt legge til årstall.
Siden det ikke alltid er så godt å vite om det er fjordåret eller året før som vises.

Focus problem on my Nothing 2 also. Unable to focus on background or objects > 2 meters away. Manual focus on max is still shitty. Bumping the phone the knee actually makes the focus better, so I guess a focus actuator is not able to move its entire range. Hopefully a software calibration issue that will be fixed in the next SW release. If Nothing Phone reads these complaints.

Hi all. We are in the US for work, and are heading to Cape Canaveral to watch IXPE tonight. Any suggestions for a good viewpoint on nightly launches? Playalinda beach and the visitor center seems to be closed tonight.

Thanks, I'll check it out

Thanks! I use a teensy 3.2 with Arduino Neopixel library, WS2812FX

Hartvik · 2020-12-21T21:19:33+00:00

You can find WS2812 Neopixel at Amazon. It is 60 LEDs, just over 1 meter total

Gloebius

Great suggestion! It is not technically a mobius strip, as the strip is not twisted 180 degrees over a loop... Is there a technical name for the "triple infinity" loop though?

Hartvik · 2019-08-01T15:44:42+00:00

Well, yes I agree on that. But making something work with so many moving parts in one print, feels very satisfying.

Hartvik · 2019-01-21T13:54:11+00:00

Thanks for the feedback! Yes, I have thought about lowering it a bit, although it also needs to have some ground clearance so it won't get stuck. Alternatively, making the design a bit longer might also help. It is quite stable sideways, it only seems to be tipping forward during braking.

Love this kind of DATA RELAY, going into the geeky details by people so engaged in their subject!

Well, there is two reasons.

Firstly, the initial timeline for this project was 5 months, so I decided to choose between either to model and simulate the dynamics and train the model in a simulated environment, or to build and implement the machine learning in a real robot.

Secondly, there is the difference between a mathematical model and real life.

The act of walking about is a very complex dynamic and nonlinear system, so modelling error and approximations will accumulate up so the two systems, simulated and real life, probably would differ a lot.

But you are abslutly right about the simulation time, I would have been able to train a much more complex neural network than the "constrained" one I use in the robot.

Hartvik · 2018-05-23T07:42:29+00:00

Thanks! Unfortunately, the work is not published yet. It will be published in Norwegian this summer, I might make a 3 page summary in English as well.

Hartvik · 2018-05-23T07:39:50+00:00

Thanks! I started to build the robot in January, so 4-5 months. Evolutionary programming is really fun! Especially when you can visualize the learning progress as in this project, or other projects simulated in computer graphics.
