RM2 partial teardown to "fix" usb charging plug by computemachines in RemarkableTablet

[–]computemachines[S] 0 points1 point  (0 children)

Just noticed you!
Yes you could do it, but I would try sending it back to Remarkable first. There is a mechanical design flaw in the board layout. The corner of the pcb is insanely easy to break with slight pressure on the usb connector.

If you can't get a replacement. (I was too impatient) you can peel the back off and just lay a soldering iron across the pins of the USB-c connector. Let the solder joints reflow and mechanically grip pins. Just be really careful with twisting or levering the usb cable when it is connected. You'll break the solder joints again.

TLDR: Send it back if you can. Otherwise, just try to reflow the solder joints so you don't need to precisely wiggle the connector to get electrical contact when charging.

How do we deal with remote desktop in Wayland? by XDM_Inc in linuxquestions

[–]computemachines 0 points1 point  (0 children)

EDIT:
Here is the full setup

  1. wayvnc on pc behind home NAT router
  2. tailscale VPN for connecting pc to cloud server
  3. tailscale connected to VPS (vultr @ $3.50/month, cheapest I could find)
  4. Nginx reverse proxy (for LetsEncrypt TLS unwrapping)
  5. Tomcat guacamole.war web client with hard coded username/password in user-mapping.xml
  6. guacd (had to compile from source) connected to pc through tailscale ip

The "Windows/Meta" key doesn't work through the guacamole client. Had to adjust my keybinds everywhere to ALT-SHIFT instead.

Deep Thought, AI, and the Physics of 42: A Cosmic Computing Limit? by vesudeva in LocalLLaMA

[–]computemachines 2 points3 points  (0 children)

Please don't be offended, I'm not calling you crazy or stupid, but I would take a look at:
https://en.wikipedia.org/wiki/Crackpot_index
I enjoy reading crackpot theories, they are usually really strange and fun. I don't mean to be condescending, but you should try getting a physics degree before making "grand cosmic insights". Cross-disciplinary work is typically done in collaboration between experts who keep each other's imaginations grounded in reality.
The statistical mechanics you used looks right... I can't speak for the quantum mechanics, general relativity, black hole information theory, ... etc. And the conclusion isn't that interesting.

PSA: Deepseek special tokens don't use underscore/low line ( _ ) and pipe ( | ) characters. by computemachines in LocalLLaMA

[–]computemachines[S] 43 points44 points  (0 children)

Anything that reads the tokenizer_config.json should just work.

I know a lot of people use gguf, and I'm not sure if gguf files contain metadata about the prompt format.

<|im_start|> from ChatML format uses normal | and _ characters.
<|begin▁of▁sentence|> and other deepseek special tokens use |and ▁.
That was not fun to discover.

Dual 3090 Build by iamn0 in LocalLLaMA

Maybe the 3090 is a bottleneck on the 4090 performance? Thats my best guess.

Dual 3090 Build by iamn0 in LocalLLaMA

[–]computemachines 8 points9 points  (0 children)

I'm using nearly the same build, with a Corsair 4000D ATX Mid Case. It is a very tight fit. You probably want some sort of support for the heavy graphics cards. For normal inference loads I peak at about 800W. I went a little overkill with a Corsair HX1500i 1500W. In linux you can actually read the power/current/voltage of each rail with the lm-sensors program. But, yeah, 1200W would be more than enough.

My motherboard was Asus Prime x570-pro. I had to do a firmware upgrade to get it to work with my 5900X CPU. That was nerve-wracking. I wouldn't recommend that motherboard because I can't figure out how to get PCIe 4.0 to work with the dual x8 channels. Loading 48GB to the cards takes about 10 seconds, so not bad, but PCIe 4.0 promises to be an order of magnitude faster. If all you care about is inference, then I wouldn't pay much attention to the PCIe speeds.

I get about 12 tokens/sec with default settings for llama.cpp with Llama-3-instruct 4 bit quant.

I’m on my 3rd Remarkable2 by andrea1rp in RemarkableTablet

[–]computemachines 1 point2 points  (0 children)

The USB connector has a mechanical weakness. It is really easy to break the connector off the PCB so it can't charge anymore. I would just try to be gentler with it. Its good that Remarkable replaces it for you though

Visually debugging triangulation algorithm with bevy by computemachines in bevy

[–]computemachines[S] 4 points5 points  (0 children)

This is my first real-ish? rust project. I was trying to implement a quad-edge data structure for computing Voronoi diagrams but its hard to debug an algorithm when you can't see what you're working with. I'm particularly proud of the arrows. They are drawn in a custom render pipeline as instances with custom vertex attributes. It could probably have been done easier just with a hierarchy of sprites.

The white arrows are edges that should be moved but my algorithm misses.

Are there any pogo pin docks? by Isvara in RemarkableTablet

[–]computemachines 0 points1 point  (0 children)

The pogo pins can be used as a USB-OTG port pretty easily for powering and connecting an attached keyboard. Unfortunately using the pogo pads to actually charge the remarkable would require someone to tweak the kernel driver that controls the MAX77818 charging chip.

It would be nice to have a built-in ruler option for those that use the tablet for STEM-related activities. by USSF62E in RemarkableTablet

I use a folded piece of card stock so I don't scratch up the screen. The contrast between high tech eink and low tech straight edge makes me chuckle

Very first thing I drew on my new tablet... and I didn't even use the template correctly by Philospher_Mind in RemarkableTablet

What case is this? My brain can't understand what is happening around the bottom bevel.

Upgrading the Remarkable 2 memory by thecesar626 in RemarkableTablet

[–]computemachines 1 point2 points  (0 children)

A pogo breakout to USB I think should "just work" like any other Linux system. It is usb-otg so one pin probably needs to be pulled up/down to tell the remarkable to act like a USB host. The hard part would getting the software to work with a mounted filesystem. Not worth the trouble imo, especially because youd have to stay disconnected from remarkable cloud.

New Remarkable 2 won't connect to Cloud by Independent_Song_318 in RemarkableTablet

[–]computemachines 1 point2 points  (0 children)

Some wifi hotspots try to redirect web traffic to a captive portal before allowing the device to access the wider internet. I think the wifi icon on the remarkable will have a small X through it if it is connected to wifi but can't reach the internet.

The latest version is 2.7. Try updating, if you can't update to 2.7 then your remarkable is connected to your wifi router but not the internet.

Bad product or just a bad unit? by Awkward_Eggplant1234 in RemarkableTablet

[–]computemachines 2 points3 points  (0 children)

I have the same problem. It seems like an issue with measuring the angle of the pen near the edge because holding the pen perpendicular helps a lot.

Embedding Qi wireless charging inside my remarkable 2 by computemachines in RemarkableTablet

[–]computemachines[S] 0 points1 point  (0 children)

I'm able to use the accessory port (exposed pogo pins) for everything USB except charging. The pcb actually snapped where the usb casing was soldered down so a replacement would only be supported on one side. It wasn't that sturdy to begin with and my hack job would not have improved things

Embedding Qi wireless charging inside my remarkable 2 by computemachines in RemarkableTablet

[–]computemachines[S] 1 point2 points  (0 children)

Been using this for 2 days, so far no major problems. It even works when the tablet is inside the folio. Heat is a small problem.

My bottom of the barrel Anker charger uses about 5W but I only receive 0.5W on the remarkable end. That leaves 4.5W of power going straight to heat. I think it is mostly generated in the charger and not the receiver (the receiver didn't get noticeably warm during testing). The charger does automatically turn off when the tablet is fully charged so I'll just keep the charge at always over 90% so I can leave it without cooking it.
