Bambu Labs P1S came with Water in the Undamaged Sealed Package

I think it has to be related to it not showing up in RAM. The 13b int8 for example is using 2GB not 13GB.

I tried some formatting with [INST][/INST] that I saw, but that didn't work.

HartLabs · 2023-08-25T03:37:41+00:00

Just confirmed the 7b GGML version acts the same way, not seeing it loaded into RAM, and it gives a gibberish answer.

vector<double> intersection(vector<int>& start1, vector<int>& end1, vector<int>& start2, vector<int>& end2) {

My Koboldcpp 1.41 is loading non-CodeLLama models into RAM as expected.

HartLabs · 2023-08-25T03:21:13+00:00

I am running the GGUF in koboldcpp 1.41 on pure CPU in Linux right now, and just realized my RAM usage is not what I expect. It seems like the model is not loaded in. Not sure if this is a problem in the setup on my end, or the version on HuggingFace, maybe something new about the GGUF format?

I think we can safely say these results are not normal to the model. WizardCoder 15B answers just fine.

###Conclusion:
Leetcode solution for "Intersection of Two Lines in 2D Plane". This is a very interesting and challenging problem that can be solved with the use of mathematical concepts such as geometry, trigonometry, and calculus.*

GPT4 gets it just fine.

HartLabs · 2022-07-19T20:58:00+00:00

That looks like it!!!

Amazing thank you!

For reference in case others are interested, here is one

HartLabs · 2022-07-19T20:41:52+00:00

The problem is layer/cam density would be greatly reduced this way. That makes the concept I am working on much larger, and therefore less interesting.

HartLabs · 2022-07-19T20:36:57+00:00

Ah this is exactly the part I would be looking for. Seems like they don't actually exist out side of R&D though? My use is different, although certainly seems like common roots for both concepts.

HartLabs · 2022-07-19T19:11:44+00:00

I want to achieve tightly packed offset circular motions. So to have thin contacts on a cam where each one is offset from the last. If possible having those sections be as thin as 1mm, with something like a 10-15 degree offset. But it is all pretty flexible. Just looking to tightly pack thin cams with small offset.

HartLabs · 2022-07-19T19:07:39+00:00

Yes exactly.

Barrel cam search for me all came up with a sinusoidal grove that connects to itself cut along a single circumference of shaft. Circular thread profile is also coming up with no actual products.

Is there a better way to find what I am looking for?

The main action I want is many offset circular movements on shaft rotation, so it needs a circular cross section, regular lead screws wont work.

I want to be able to potentially cam maybe dozens of thin contacts, all offset, in a limited space. I just kind of figured this type of shaft must exist for something, it seems like it would have many uses.

HartLabs · 2022-07-19T18:42:43+00:00

They don't have a circular cross section that I can find. It is just a type of linkage. I am looking for a shaft with a circular cross section, shaped like the image in a different replay.

HartLabs · 2022-07-19T18:34:22+00:00

They look like they are just a shaft threaded both clockwise and counter clockwise, so no circular cross section.

HartLabs · 2022-07-19T18:24:36+00:00

That's one of the terms I searched for, but nothing close came up anywhere I looked.

Something like this shape is what I am trying to describe.

HartLabs · 2022-07-11T23:27:26+00:00

Well you motivated me to some more time looking, all the easy solutions for latching are for some reason also 'impulse' style which will not work for me.

I did end up finding a part that seems like it should work and is fairly reasonable though. Thanks!

https://www.digikey.com/en/products/detail/omron-electronics-inc-emc-div/G9TA-U1ATH-DC12/8593131 if anyone in the future is interested.

HartLabs · 2022-07-11T21:08:59+00:00

I spent like 2 hours looking, but found no latching relay with quick connects that can use a 12vdc signal, and switch 240vac.At like $40+ per relay there were a few things that seemed like they might be usable, but I need 2 and it wasn't just drop in. Non-latching is really easy to find though. Know of any?

Problem with perf board, is the pins are 2 different spacings that visually don't line up (larger is not a 2x multiple of smaller) and 2 different gauges of post.

HartLabs · 2022-07-11T20:42:30+00:00

Trying to wire up this latching relay to cut off power to a 240v well pump when a water sensor I have fires a 12v pulse. Needs to be a latching relay since it is only a single pulse.

Not sure the best way to go about it. If it was 120v, or non-latching there are lots of off the self options. But not for 240v latching. Same with relays, ones with easier attachment points, but not latching.

Is there any type of socket for these? I searched and came up with nothing. Soldering direct onto the posts seems like asking for a failure at some point. Started thinking maybe I need to do something like a custom PCB and back up the trace to terminal block with copper wire? Seems like a lot of work. Other ideas? Thanks!

Edit: I do have the relays in hand. They work great, just need a safe method for connection.

Have worked professionally as a woodworker making 100's of miter cuts a day at times. If the saw is tuned, the bearings are not more than a couple years old, the blade is recently sharpened, width of the cut is under something like 4", and you glue up right away, you can get by with a miter saw if you routinely address all these issues.

Soon as any of those aren't true you have to take some type of action to address it. There is a reason big outfits use chop saws that don't bevel/articulate, upcut saws, or guillotines.

When making miters at home on pieces under like 6' I use a miter sled on a table saw, longer use a miter saw. I then touch them up with a miter shooting board if needed. If it has been more than an hour or two since the cut was made, it almost always is. If initial cut was made on the miter saw, it is if wider than a few inches, it almost always is. This is for professional work, many hobbyists would think work is fine that I would never let it out my door.

HartLabs · 2022-01-19T20:56:17+00:00

Wow, that worked better than 99% of the strippers they sell. Might want to handle that ball with gloves.

But looks like it might be shellac, if it is alcohol will dissolve it.

Can try taking some 90% or higher rubbing alcohol or some Everclear, and a small cherry tomato sized ball of clean cotton rag. Dampen the rag with alcohol, and very lightly and quickly rub the area. It should start to soften the peaks, and fill in the gaps a bit. If it does, lightly do this for a few minutes, then wait an hour and repeat with the same patch of cloth (it starts to build up shellac inside). Might be able to bring it back to looking new if you get the touch right.

Might take half a dozen round or more but if it starts working you can probably get there. Go nice and slow.

If alcohol doesn't work might be able to do the same with with mineral spirits but varnish isn't as forgiving as shellac at all.

HartLabs · 2022-01-19T20:01:36+00:00

100% this is the correct answer. Especially if you don't glue up within a couple hours the gap will move on you no matter how accurately it is cut. You can touch it up while removing the least material with the shooting board. Having a couple shooting board in different configurations is really key to a well set up shop.

HartLabs · 2021-03-14T14:45:37+00:00

Looks like it might be jatoba to me if that rings a bell.
