Yus!.. you are right. But sometimes i feel worry about the future.

Mmelta101 i am also in search of oscilloscope

techielewOP•10/27/24, 11:42 PM

@melta101 I think you were looking for a headless scope: https://www.picotech.com/oscilloscope/2000/picoscope-2000-overview

USB oscilloscopes & mixed signal oscilloscopes

A powerful pc-oscilloscope, spectrum analyzer, protocol analyzer and arbitrary waveform generator that fits in your pocket.

Hey Brandon
This is quite nice. Has a lot of functionality which I normally would like to have
But it's a bit on the expensive side
569$(excluding the import tax).
I am keeping my budget to around 200$

Maybe it's time to save coming forth

I think it is a trap to reduce AI to just LLMs - I agree LLMs wont solve everything. I think LLMs will provide the "Human interface" for AI tools which can reason.

And I agree with this quite a bit especially where its a trap to reduce AIs to just LLMs @Ming @32bitSaviour @Undefined @kristof-at-embeetle Has any of you met non LLM and perhaps non vision AI in the world. It would be interesting to see what people think or have encoutered

ZacckOsiemo•10/28/24, 4:31 AM

wait that means you can say something. How did you use AI with RADAR system?

melta101•10/28/24, 4:31 AM

using data from freq spectrum

Mmelta101 using data from freq spectrum

ZacckOsiemo•10/28/24, 4:32 AM

How were you using that data? Can you be as explicit as you can manage please?

melta101•10/28/24, 4:35 AM

so every countries RADAR's has its signature
but it is Obfuscated.
it is easy to detect RADAR. the problem comes with finding which RADAR is friend or foe.

melta101•10/28/24, 4:35 AM

ZacckOsiemo•10/28/24, 4:38 AM

at some point this is just a memoization problem. A tasty one at that

melta101•10/28/24, 4:38 AM

it would mostly come into ML

where do you think the edge between AI and ML lies?

btw a side note you do a lot of defence work, which I find really cool

ZZacckOsiemo but the signatures?

as the signal deteriote. the signature will as well
so there is a need to upsample/reconstruct it.

I may choose the same, just because I know someone I can ask questions.

segfaultdev.elf•10/28/24, 9:51 AM

when you build a custom dev board what things you guys consider share some knowledge with me please.
For example I want to make a custom stm32 board with on board mpu6050 and can transceiver now as for powering up the mcu which is really staright forward due to st's
application note but when it comes to providing power for the ADC where I struggle always I don't know what is the exact value of noise that my board can produce and what is the exact
filtering components i should use for example: LRC, RC, RL, Ferrite bead filters

Hi all - I've been looking at adding controlable LED lights to a project I have. I have 8x 1m lengths of these

Which I daisy chain together using these;

https://thepihut.com/products/3-pin-led-strip-connectors-strip-to-strip-10mm

However I need to inject power about 1/2 way due to the voltage drop? Can anyone recommend a strip connector that would acccept the additional 2x wires? As I think if I start soldering in the addtional waires to the ones above they wont close or will break?

Any suggestions please?

Hemal•10/28/24, 11:08 AM

For dev board design, here are some of the points that come to mind

make sure you breakout all the pins of MCU on the header and label them clearly.
- I'd also have multiple 5V and 3V3 pins for connecting various modules.
Must have a Reset button
One or more LED connected to a GPIO, add RGB if there are lot of GPIO on the MCU.
accessible programming interface, preffereable on edge of board rather then in middle
4x Mounting holes. I'm not sure of your board shape, 3 might do but 4 is better.
User button
Solder jumpers or normal ones for boot configuration.

Now when you ask for powering ADC, I assume you mean reference power supply for the STM's ADC.
AFAIK there is an internal Vref. You could possible use that.

segfaultdev.elf•10/28/24, 11:11 AM

Not the VREF+ it is VDDA which I am suffering for

segfaultdev.elf•10/28/24, 11:12 AM

if my VDDA is stable enough i can just connect it with VREF
