TrainBLD - NEW web timer that reconstructs your 3BLD solves

[Pfannkuchener]

Hi @rotobld

I currently solve 3bld with M2/OP with Buffers DF and RDF and want to swtich to 3-Style with buffers UB and URF.
For learning the 3-Style-Algs I am looking for a tool/timer, where I can specify a subset of algs I currently want to learn and have scrambles only for a certain subset of targets.
E.g. I want to practice all edge-algorithms, where one (/the first) target is UB. Afterwards I would maybe want to practice all edge-algorithms, where one (/the first) target is UR. Afterwards I want to pracitce all algorithms where one (/the first) target is UB or UR together. ...and so on.
In csTimer you can practice subsets (OLL / PLL / ...), but I haven't found something similar for the case I explained above.
Do you consider implementing something like that?
Or do you know a timer/tool, which can already do that?
I have several bluetooth-cubes, so I really look forward to use your TrainBLD in the future. I hope you can fix it soon, so I can try it out

I also want to say thank you, that you share the Code in github: Thank you! I will have a look into it when I have time.

Hi!
I will see what is the problem and fix it, probably in the upcoming week

Thanks Roto, that would be awesome. Sorry late reply, only just saw your post.

Awesome!
Just started doing 3BLDs solves and I want to test your site to see how can it help me to improve

Maybe you could use some alternative to heroku, maybe glitch.com platform or something like that. At least it works fine with pyhton projects with flask framework.... I am not sure if it'll fit for these project

Yeah It's been like this since a while :/

although couple of years gone by, but better later than never,
managed to get trainbld.com up and running again

Thanks for getting this tool active !

Anyone has any luck connecting the GAN i3 smart cube to the trainbld tool?

For me it is stuck on "Connecting...."
When I see the console, I see this error print,
Uncaught (in promise) NotFoundError: No Services matching UUID
0000180a-0000-1000-8000-00805f9b34fb found in Device.

Hello @rotobld ,
Are you still maintaining this tool? Have you tried to implement detection of canceled moves?

Hi!
Unfortunately currently I don't have the time to add new features to the website. I only make sure that it is up and running

Hi! I'm happy to announce that I have made major upgrades to Custombld.net (with a lot of help from Claude Code! ).

These changes bring me one step closer to my vision of creating a single website that contains all the tools needed to help people train and improve more efficiently and deliberately in blind events.

I merged Trainbld.com into it, so now you can use your smart cubes on the website to get your solves analyzed!

You can see further information about the changes here:

Thread 'CustomBLD.net - New tool for custom scrambles in BLD events!'

Hi!
I made a new BLD training tool I am very happy to share
CustomBLD.net is a website that helps you with generating custom 3/4/5BLD scrambles.

you can change the parameters of the:

• Number of algorithms in the solutions
• Presence of parity
• Number of edge flips
• Number of corner twists
• Number of solved pieces
• Number of cycle breaks
• etc....

You can see a short demo video here,

I hope this tool can help practice BLD events more efficiently and deliberately,
I think that our community have a lot to develop with how to practice better and I...
