Hi!
Quick reminder, I have been working on making 3BLD training more efficient.
So after this, this and this I realized that the software isn't accessible enough,
So I decided to develop a web timer that will implement my software (and learn a lot of JS on the way )

Very happy to introduce: TrainBLD.com

TL;DR

Main features:
  • Reconstruct 3bld solves : commutator seperation, move count, letter pair, execution time, memo time, fluidness (execution time without pauses between algs), solve description (12'/8''), timer per alg. (If you have more ideas for analysis features, I'll be glad for suggestions)
  • Fully coustomizable : buffers, letter scheme
  • Support 3Style, M2, Old-pochmann, Orozco
  • Link to CubeDB or TXT format
  • Works best with Rubiks-connected/Go-cube --> Gan356i (I think specific my cube has problems) --> Giiker (didn't managed to implement it good enough)
  • Export stats : all solves are saved, mo3, ao5, ao12, mean all
  • Execution mistake recognition
  • only on Chrome (because of the support for bluetooth API)
Example solve
CubeDB
14/9 35.97(0.44,35.53) 51.51%

I know that this not the most elegant timer, but I thought that after people will use and see the potential, more timers will implement this feature.
My goal is to make more people enjoy practicing 3BLD and I know it can be very frustrating to try to learn from your DNF's.

The website itself doesn't analyze the solves, but a HTTP server I developed,
I put a lot of effort so that every web-timer could analyze 3bld solves as easy as possible.
If you are a web-timer developer (that supports smart cubes), checkout this to see how to implement this feature into your website, it is very easy!!
If you need help feel free to contact.



Last thing, Tanks a lot to CSTIMER (bluetooth API to smart cubes), cubing.js and Gil (CubeDB), great software that helped a lot.

Wow nice effort. I am quite happy to follow your BLD coding projects and your updates.

Please excuse my horrible attempt of a solve; following along to memo generator

https://www.cubedb.net/solve/347

I use wide u moves for edges. But the parser shows D instead of u' and when doing either L or R in the alg it shows a B move
For example for the edge N (RB) I use the alg u R u' M2 u R' u' but it's parsed as D B D' M2 D B' D'

Is there any way around this?

This is a good question that I have thought a lot about.
The main problem is that if i would change it to support wide moves then someone would say the opposite
that he did D B D' M2 D B' D' but the parser showed u R u' M2 u R' u'.
It is a hard to write a software that "guesses" if you did D or u, practically it makes the same changes on the cube (ignoring the rotations)

So there are 2 solutions:
1. 100% right - relying on cube gyro. from my experience it is more difficult both because of gyro reliability and software implementation.
2. probably 85% right - I think that it is more common that you would do u R than D B in 3BLD, so creating a set of rules should do most of the job.

This is one of the features I'll work on adding

3. Give user an option "I did this with wide moves actually" and remember user preferences

Rotobld could this work? Maybe in settings after letter scheme a place where you could choose your preferred algs? I only know M2 so I don't know how much of a headache this would cause for you with other styles like 3style. With M2 I know of B, wide and x moves ie for (LF) I know 3 algs but use the wide..
F (LF)
- x' U L2' U' (M2) U L2' U' x
- L2 u' L' u M2 u' L u L2
- B L2 B' M2 B L2 B'


edit: TBH the wide algs are only small and easy to copy/paste from my alg spreadsheet to the parsed cubedb page. lol I am probably just being lazy as I am sure there are more important features to get going first. Still great app mate. I am all aboard the trainbld bandwagon Choo! Choo!

I think this could work, it may cause the data size sent to the server increase dramatically.
but if it will be for specific algs it should be fine.
Hope to make an update in the next couple of weeks

I had been busy in the last couple of months with other projects
(mostly documenting old projects like this LEGO Rubik's cube scrambler)
I decided to add some important features to trainbld.com before moving (almost) completely to other projects.

features added:
mobile support - mainly changed the layout so it will look nicer. currently only works on android phones with the Chrome app (ios doesn't support web BLE)
Moyu AI support - this cube is amazing, the best smart cube I tried. this is the kind of cube I imagined when started developing the timer three years ago. I think this cube solves the smart cubes hardware issue and would make more people start using smart cubes to train 3bld. The last drawback is the price, hope it will get cheaper in a year or two.
wide moves instead of D B moves - as you suggested, I converted D B D moves to wide moves. I have done it by applying these rules (if you have more rules that should be added, send me).
D B D' => u R u'
D B2 D' => u R2 u'
D B' D' => u R' u'
D' B' D => u' L' u
D' B D => u' L u
D' B2 D => u' L2 u
customizable cube orientations - a very important feature I didn't support.
If you used the website before, you need to click "Save Settings" so the cube orientation will be updated.


with these features implemented, I feel that the main idea of the timer is accomplished.
I would probably not develop more features for the next 4~5 months, but send me ideas for features for the next development session.
If there are bugs, send me and I would try to fix them in a week or two.

Hey Roto. Any way of moving the the text done for scrambling down a bit from the main scramble? The scramble (highlighted in yellow) gets over lapped by the movement text when scrambling. Maybe be a problem my end, as TrainBLD never wants to fill the whole screen when I use it. Using Chrome btw
