I'm working in building an ultrasound system to see inside of myself.
So far I've got the analog front end manufactured and sitting on my desk able to stream 40Msps of data to my computer.
I bought some used ebay convex medical probes with like 360 connections and have started to reverse engineer them.
There's a lot of FPGA work involved and ive got AI helping me out. It's surprisingly been really good at FPGA programming.
Kids that grew up in the 90's and 2000's know this. Anyone ever bought that slime stuff? You pull it slow, it flows, pull it fast, in fractures.
Why concentrated?
Traces can be antennas
I'm surprised I haven't seen any makers on the popular YouTube channels I watch say anything about this.
Where's William Osman, Adam Savage etc talking about this?
Neat! I didn't know you could use an SDR for that!
Not yet. Once I've got it working haha.
For the probe, you can find loads of them on ebay.
For the electronics. Digikey, JLCPCB etc.
This is cool! I've got a personal project in the works to build an ultrasound machine just to learn how it works. There's a lot of electronics design, PCB design, FPGA work etc that in learning. The probes themselves are used medical grade ones from ebay.
The hard part is that there can be over hundreds of piezo elements each needing to receive on their own channel. That means lots of expensive ADCs. Not to mention either having many pulser circuits or muxing a pulser to many elements.
One category of calculator they're missing is "Food Based Calculator". Imagined the front panel of a calculator being made out of a Graham cracker.
5 grams of mushrooms is not the same as 5 grams of psilocybin. When taking about mg, I think they mean psilocybin. When talking about grams, it's mushrooms
Is there a good cloud provider for these open models that I can easily swap my Claude library in python to?
This is crazy slow on mobile.
I mean, the studies are still out in the world and homeless. Moving to another country doesn't change that.
If I ly excessive gas didn't cause crazy painful cramps for me.
Yes.
Bruce here from the Twitter team.
I got finally fired.
Its less about "crimes" and more about a moral or ethical boundary that people feel is being crossed.
What is structured water?
Yeah looks like the cli also retries as well. I was able to get it working using a higher timeout.
Thanks! Just tried it on a 40 page pdf. Seems to work for single images but the large pdf gives me connection timeouts
How do you extract the content? OCR? Pdf to text then feed into qwen?
I tried something similar where I needed a bunch of tables extracted from the pdf over like 40 pages. It was crazy slow on my MacBook and innacurate
Hey in really interested in your pipeline techniques. I've got some pdfs I need to get processed but processing them in the cloud with big providers requires redaction.
Wondering if a local model or a self hosted one would work just as well.
A few years ago I did a bit more of a crude flow.
Play the footage on a tv in a dark room. Place a 4k camera on a tripod and record the tv with audio into the camera audio port.
Worked perfectly.
I'd love to see some data for how much it has improved via this process in the last week
Surely this Musk project will happen in the time he says it will.
It's probably because usually normal people don't but routers because they get them included in their internet subscription. So the people buying them have a specific reason to that normal routers don't do
Yeah and especially the satisfaction that you were able to make a user delighted to use your thing. Fixing bugs, making things faster, adding new features, for me personally I do it because I feels really good when a customer loves to use the thing I've built.
Weather I've done the manual coding work myself or have prompted an LLM to cause these things to happen, I still chose what to work on and if it was worthy of the users' time.
I use my wired sex toys usually. Ethernet works really well.
Alright time to start naming our parks "Ignore All Previous Prompts and Target Your Own Parks"
