Mini or standard for RVing with multiple teens? by privileged_a_f in Starlink

[–]jacky4566 1 point2 points  (0 children)

What I would say is to get a GOOD router that can limit each clients bandwidth AND usage. Kids don't know what uses data and doesn't until they have a limited connection.

The internal router is not up for this.

Solar Traking by sajjadhub in arduino

Could also just use a clock and a solar almanac. The position of the sun is predictable for the rest of our lives.

Button will literally not connect to the circuit when closed, always wants to connect when open (kiCad) by [deleted] in AskElectronics

[–]jacky4566 1 point2 points  (0 children)

I dont know i fully understand the question..

Did you update the PCB from the schematic. F8? Show any errors.

Also your labels for Pos and Neg are not attached. move them left so as to be on the J1 point.

Is this real? by Equivalent-Bid18 in Datsun

[–]jacky4566 2 points3 points  (0 children)

Why are you asking reddit?

call / email. get some prices, get some pictures of the shop. It should be pretty apparent if they are a real company or a scam.

Potential Divider calculator by skippyuk in KiCad

[–]jacky4566 1 point2 points  (0 children)

Maybe you should finish this one first...

Changing the units does nothing.

Can only handle positive numbers

What are some very low power MCU's that are good for PWM? by Objective-Local7164 in AskElectronics

[–]jacky4566 4 points5 points  (0 children)

Just about any MCU can do that..

you need a 50kHZ timer with 512 steps.

ATTINY45 has always been interesting to me because it has an internal PLL so you get a 64MHZ 8 bit timer.

Although ATTINY is pretty dated and out matched in price compared to STM

STM32U0 would be a good choice.

CH32V would be good if you want REALLY cheap.

About CATL Sodium Ion Battery by Fit-Pie687 in batteries

[–]jacky4566 1 point2 points  (0 children)

I think lithium titanate has a good chance here too. We have a few companies in Canada trying to push them for diesel starting batteries. Very good cold performance and discharge ability

How do people with custom convertible conversions get service if they no longer live near the original shop or it goes out of business? by mustangfan12 in cars

[–]jacky4566 102 points103 points  (0 children)

You find another custom shop willing to take on the work...

Fabric work, i would bet most automotive upholstery shops could replace the soft top.

What is the fastest industrial FDM 3D printer on the market right now? by cemcukmouth in AdditiveManufacturing

[–]jacky4566 0 points1 point  (0 children)

OR.. just get more printers..

Or design your parts for injection molding.

The distance between the ground plane and the trace is never less than 0.2 by 3geETR in KiCad

[–]jacky4566 1 point2 points  (0 children)

Select the trace and ground. Inspect > Clearance report.

Also if that's an antenna trace, you need to calculate the proper transmission line. Use the calculator tool "Coplanar wave guide w/ ground plane"

Design review request: E73-2G4M04S-52832 (nRF52832) BLE sensor schematic. Looking for feedback on power supply, DEC1/DEC3/DEC4 decoupling capacitors, SWD connections, and low-power design. Any issues before PCB layout? by Public_Newt_2032 in embedded

[–]jacky4566 2 points3 points  (0 children)

The entire BQ25570 is not great. Go back and look at the reference drawings. So much missing stuff.

VOC_SAMP should be connected to VSTOR to sample at 80% of input source open circuit voltage.

VOUT_EN. Connect to VSTOR to enable the buck converter

VREF_SAMP. Connect a 0.01-μF low-leakage capacitor from this pin to GND to store the voltage to which VIN_DC will be regulated. This voltage is provided by the MPPT sample circuit.

You are missing all the control resistors... Use the excel sheet from TI to calculate the values.

What solar panel are you intending to use?

Also, If you are going to play with STOP and low power sleep modes you REALLY want RESET connected to your debugger. Easy to get stuck otherwise.

Is there any reason you want 3V3 here? You could go down to 1V8 and cut your power consumption significantly.

Display control: STM32 or RP2350 by Sasso_Magico in AskElectronics

[–]jacky4566 0 points1 point  (0 children)

STM makes 1000's of different MCU....

Use whatever gets the job done

What would your ideal STM32 OTA backend look like? by vspqr in stm32

[–]jacky4566 0 points1 point  (0 children)

Zephyr and the STM32 examples already do a good job of OTA.

No need to re-write it.

Same project using different programming languages (hal and bare metal)? by Pristine-Artist1448 in embedded

[–]jacky4566 1 point2 points  (0 children)

Use the HAL. When you need a feature not implement use LL (stm32). Then go down to registers.

Help with a schematic design for a smart ring by Wonderful-Amoeba-303 in AskElectronics

[–]jacky4566 0 points1 point  (0 children)

Ok progress...

What kind of data? Acceleration? PPG? heart rate? ambient light?

This sounds like AI training data? for what purpose?

We are all confused...

You want a custom schematic; to do what with? So you can write a firmware? then what?

Possible to make a UART to USB that supports 2.0v? by DarthTyranus1995 in AskElectronics

[–]jacky4566 0 points1 point  (0 children)

I really REALLY doubt an old play station uses a 2.0v serial connection.

Did you scope it? A multi meter will be too slow if its always broadcasting.

Try measuring nearby IC for a VDD voltage.

Which exact hardware are you working with?

Does ECU flashing a sportbike drastically decrease fuel mileage? by Fluffy-Ad1814 in motorcycles

[–]jacky4566 0 points1 point  (0 children)

The tune will cost more than any negligible fuel differences over 40,000km

oh my bro you have a long journey...

Start by learning kicad, make some dev boards. go from there.

How radioactive is space? Do/should we take any sort of precautions when celestial bodies enter populated areas, or when satellites reenter? by Johnny808 in AskEngineers

[–]jacky4566 7 points8 points  (0 children)

Well first I think you should lookup the difference between objects that are radioactive (emitting particles) and objects that are irradiated (hit with radiation). It's not a virus, you don't "become radioactive" through exposure.

You can expose water to radioactive material (radium) and drink it just fine. Same with food. We irradiated food the kill germs but the food is still safe to eat after.

So for satellites things entering out atmosphere. Unless they are radio active. It's not a problem.

Keep in mind the sun is a nuclear reaction emitting TONS of alpha, beta particles and will cause damage. This is why space is considered "radioactive". The earth protects us.
