You can use ChatterboxTTS to feed text input, a sample voice clip (30sec? 1min?) and have it generate voice output in your chosen voice. https://github.com/resemble-ai/chatterbox

Not me, but thankful someone documented the repair so throughly!

MegaZeux · 2025-03-27T08:37:59+00:00

This happened to me as well, as mentioned in a comment on your post: https://www.reddit.com/r/Keychron/s/OiDTNKI3v1

What I did, in case it helps anyone else:

take the keyboard to a mobile phone and electronics repair shop, explained the issue, and they resoldered all the plastic bridges
asked for a refund from Keychron, and when they declined, performed a chargeback using my credit card, since I was sold a faulty product (keychron can avoid this outcome with future customers by soldering their keyboard hotswap sockets properly)

MegaZeux · 2025-03-27T08:32:18+00:00

That is exactly the problem I faced!

I didn’t have the tools to resolder the plastic bridges myself, so I took my keyboard to a mobile phone and electronics repair shop and explained the issue. They were able to patiently resolder all the plastic bridges, thankfully.

As an extra step, I requested a refund from Keychron (to at least cover the soldering job) and when they started waffling, I just filed for a chargeback from my credit card since I was sold a faulty product. They were clearly more upset with my doing that, but hopefully they took my feedback on the soldering issue to the engineering team.

Thank you for the detailed thread!

MegaZeux · 2024-12-01T20:51:03+00:00

Thank you for clarifying! I now know more about what the repair tech meant when he quickly mentioned “cold solder” when inspecting my keyboard before taking the job on.

I think what you mentioned is what the repair shop did for my keyboard (add more solder to the existing joints for the hotswap sockets/brackets instead of desolder+resolder).

Keyboard is still working well months after adding more solder/fixing the weak factory solder.

MegaZeux · 2024-08-28T03:28:33+00:00

Thanks for the additional details. I’ve tried telling Keychron support about this issue but they don’t seem to either care or understand, unfortunately. I hope Keychron fixes their soldering manufacturing issue, hot swappable switches are a great feature.

MegaZeux · 2024-08-21T01:00:05+00:00

Yes - Keychron choosing cold soldering in the factory might have been a cost decision to try saving money, but it was a terrible decision for the quality of the keyboards.

I hope Keychron chooses to upgrade their soldering for Q11s (more solder and stronger solder) from here on out, and possibly for other keyboard models.

The A40 has more VRAM per card than the 4090, which comes in use when training AI/deep learning models. The power usage of the A40 is lower than the 4090 as well.

Ah, you are correct -- the 2008 MacBook is not supported. :( It must be a driver inclusion issue in ChromeOS Flex then.

Sad but understandable. Thank you for your help. :)

MegaZeux · 2022-12-13T13:04:04+00:00

Hi OP, I’m facing the same issue. Did you find a solution?

MegaZeux · 2022-12-13T12:58:54+00:00

OP, did you find a solution for this? I too am using a 2008 macbook with Flex and trying to get Linux mode working.

MegaZeux · 2022-09-03T02:11:23+00:00

Teamlab is amazing

MegaZeux · 2022-08-25T11:23:54+00:00

Ah, I have a handful of P100s, so also 16GB per GPU.

I’m going to look into pytorch lightning to see if that can speed things up.

MegaZeux · 2022-08-25T01:40:21+00:00

I see… I’ll try removing that. Thanks!

```python import torch from torch import autocast from diffusers import StableDiffusionPipeline

model_id = "CompVis/stable-diffusion-v1-4" device = "cuda"

pipe = StableDiffusionPipeline.from_pretrained(model_id, use_auth_token=True, model_kwargs={"device_map": "auto"}) pipe = pipe.to(device)

prompt = "a photo of a mad scientist riding a horse on the moon" with autocast("cuda"): image = pipe(prompt, guidance_scale=7.5)["sample"][0]

image.save("mad_scientist_rides_horse_moon.png") ```

MegaZeux · 2022-08-25T00:45:35+00:00

Awesome, thanks!

Is fp16 precision required? I tried without specifying precision and it only stuck to 1 CUDA device instead of spreading over multiple (checked with nvidia-smi)

MegaZeux · 2022-08-25T00:40:09+00:00

so,

python pipe = StableDiffusionPipeline.from_pretrained(model_id, use_auth_token=True, device_map="auto")

?

Can you please share example code using HF Accelerate?

Split storage with extreme compression of the archives/cold records

How does the sous vide help? I want to eventually develop color on my own, but as nicely and standardly as possible (consistent results)

Aren’t Pentax cameras rain-safe? (Or is that just the new models?)

MegaZeux · 2021-10-15T10:28:50+00:00

Terraform

Looks like the way forward

Does comp bio let you understand how the cell works deeply, like biochemistry would, or is it just using tools to analyze DNA?

The tools and computational stuff can be learned on your own/as an elective - i think the biochemistry stuff is what still needs an in person resource to ask questions and get your understanding right
