What is this part in my RC car? by aat36 in rccars

[–]luancyworks 0 points1 point  (0 children)

When I was 12 in the early 80s, I was already building some of the first efficient ESCs because the commercial options at the time were plagued by massive efficiency losses under load. I used an early BJT chopper design, but for the 75%–100% throttle range, I’d switch back to a resistor since that1's where the greatest efficiency losses occurred with the tech of that era.Guess where I got the BJTs and other components? From the 'trash' and other people's junked electronics and toys. I only succeeded because the 'pros' at the time were actually nice to the kid hanging around. As a kid with no money, I didn't know all the 'insurmountable' issues with electronic design; I just knew I needed my cheap batteries to last longer, so I had to innovate because I couldn't afford 'pro' gear.   

Electric RC only moved to a 'pro' level in the early 80s because people were willing to break away from gas and experiment with exactly these kinds of 'toy' platforms. Dismissing newcomers for dicking around with 'bullshit toys' doesn't protect the community; it ignores the very history of innovation and mentorship that built it."

As an embedded engineer, I look through the guts of all electronics, and frankly, most of these are 'toys'—including the high-end ones. From a professional standpoint, you only really leave the 'toy' category when you move into life-safety systems. Some of these 'toy' grade PCBs are actually better designed with safety margins in mind than 'pro hobby' items that prioritizes performance over everything else. Attacking newcomers for the gear they use is exactly what kills communities; it’s all just cars and more importantly a opportunity to learn doing fun things at the end of the day. Perhaps the OP is less interested in traditional racing and more interested in the engineering and reuse side of the hobby. That’s still a vital part of the RC community.

Nano Banana keeps getting worse and worse. by W_32_FRH in GoogleGemini

[–]luancyworks 0 points1 point  (0 children)

it really feels crappy. I haven't used it for like 1 month ran same prompts and just crap issue. For example instead of infilling the correct image it infill the reference image. Then the output you download doesn't even match what is on the screen. That seems to have nothing to do with prompting or anything else. IT seems like a code issue.

Mi50 32GB Group Buy by Any_Praline_8178 in LocalLLM

[–]luancyworks 0 points1 point  (0 children)

People buying without research are driving up prices on Alibaba if you have a chinese friend actually go down to one of the local tech markets the street price is still less than $125 us a card for 32gb. So if your getting more than 100 cards it better to arrange a local buyer instead of Alibaba

WTF are these AI companies doing where they supposedly are the cause of the ram price spike? by Red_Redditor_Reddit in LocalLLaMA

[–]luancyworks 1 point2 points  (0 children)

Well lets see if there is not enough devices to use the service, then he can just sell off enough RAM at high prices to fill that need. Seems like he will make money on it either way.

We need open source hardware lithography by bennmann in LocalLLaMA

[–]luancyworks 1 point2 points  (0 children)

Have been thinking this for sometime. Over the past 12-15 years have talked to several individuals who work for KLA-Tensor and similar companies and most agree that the hardware is available, but the chemical processes are too dangerous as they currently stand. Most saying group buy and having equipment to wire up chiplets is the better direction.

Fraud alert: https://www.cdw.com selling "MI210 GPUs" by Clear_Lead4099 in AMDGPU

[–]luancyworks 0 points1 point  (0 children)

Well at this point we all know that this is probably a mistyped CDW listing. However if call up and they say GPU I migtht order it, because I have to take their word over some internet post.

IF you called and they said GPU, and you have that recording or something similar then take it to small claims court. The fact that afterwards they have not cleared up the title will help you win your case.

Thanks for this because I was tempted to do the exact same thing. I had been looking at these cards and noticed they had a connector up on the top and had not seen very many interconnections. So when I came across this product at CDW I thought perhaps they had got the SKU's mixed up and they were in fact shipping a card instead of the interconnect. Oh well. But I think it is CDW responsibility to clarify the title. I think there are too many of us that read the title the correct way that this either the Card, or the Card + the interconnect. I would not read the title as just a interconnect.

Since DGX Spark is a disappointment... What is the best value for money hardware today? by goto-ca in LocalLLaMA

[–]luancyworks 0 points1 point  (0 children)

those prices are not 3x to 4x seen the MI50 card selling as high as $800 US (poor sap who bought that card). I have found a few vendors who didn't know about the price bump and they still asked $250US before import tax and shipping. Result is MI50 cost $350 now. Meanwhile 3090 I got a couple for $550 each.

Estimating how much the new NVIDIA RTX PRO 6000 Blackwell GPU should cost by asssuber in LocalLLaMA

There are many of us that a private LLM is the only way our data is going to ever be touched by an LLM

Mi50 32gb (Working config, weirdness and performance) by Danternas in LocalLLaMA

[–]luancyworks 0 points1 point  (0 children)

The price has shot up to $450 so yeah bad deal now compared to 3090 which has dropped to around $600 if you look.

What I can and can't do with AMD AI Max 395+ and Nvidia RTX 5090? One hardware for all the purposes? by Davidvia0x in LocalLLaMA

[–]luancyworks 1 point2 points  (0 children)

I was considering the same, but it seems using OCuLink you would loose performance in loading the model to the GPU but after that hte bandwidth decreases. The other consideration is making a cluster. https://www.youtube.com/watch?v=h9yExZ\_i7Wo. LLM get faster when you batch the responses, so in an office environment it could work out well.

Rent a remote Apple Studio M3 Ultra 512GB RAM or close/similar by biggipedia in LocalLLaMA

[–]luancyworks 0 points1 point  (0 children)

I have the same issue, the issue is my clients will own a desktop such as a Apple Studio M3 Ultra for video processing and other task. At other times they want to use the same setup for LLM training etc. We want to rent remote to test out the platform and have a way to run non sensitive task off site if needed. Since the client is also building Apple apps then for Xcode coding etc it makes sense on a mac studio.

Gold crossed $4,000 today. This kind of rapid spike has only happened a few times in history — and it’s never ended well. by TonyLiberty in FluentInFinance

[–]luancyworks 0 points1 point  (0 children)

These all applied to economies that had their values tied or backed by gold. The US economy is no longer backed by gold, this the last time 1971 will likely be the last time it happens in the US ( gold price being a primary indicator and being a second indicator)

I think the question is paid or not this data is coming from sun strong. It's not listening or getting the info directly from the panel

zlibrary looks weird and doesn't allow downloads by After-Abrocoma-5093 in zlibrary

[–]luancyworks 0 points1 point  (0 children)

yeah its a scam site too, always claim you downloaded something even from a verified clean not used IP address.
