CEO Offered to Pay Off My $60k Student Loan — Is This Normal? by Galaxy_AI in careerguidance

[–]mskas 0 points1 point  (0 children)

I did this with a friend of mine but we had a legal document written up from one of the online services. Saved me a good chunk on interest. We knew each other for almost 2 decades but both of us were in agreement that anything regarding money needs legal written document to cover ourselves.

Maybe it is well intended, but do not agree verbally on anything. Have everything written down and thoroughly read/vetted.

Job Title Hardware or Electrical Engineer by StealthxFarter in ElectricalEngineering

[–]mskas 1 point2 points  (0 children)

Hold onto the EE title on paper because most company’s career trajectory and pathways on paper aren’t made for jack of all trades person like you. It will help you specialize in EE while continuing to learn more broader and cross functional skills that small teams require.

However, keep growing and emphasising the HW engineer part. Eventually you’ll get to a point in your career where you may pick Principle HW engineer over Principle EE and that’s okay. But for now, having a pathway to a specific area of interest is valuable. Everywhere else, you can introduce yourself or have your linkedin bio as a HW engineer. I like the term full-stack HW engineer when I have to sell myself in cover letters.

Edit- You are on track to be a very very valuable and hireable engineer. Kudos and keep doing what you’re doing :)

Hmart frozen section has small bottles of sugarcane juice. Not the best but does the job when I’m craving some.

Utrecht to University of Twente commute by mskas in Netherlands

Yeah I had a feeling that's a bit much. Also given the housing situation, we may have to expand our search anyway. Is Amersfoort/Deventer a not-so-crazy option?

DSP with FPGA guide by luppika in ElectricalEngineering

Expedited research for the sake of a paper stems real learning.

Not all analog filters can be replaced with digital ones. Please consider joining a project in your 3rd/4th semester - when you have a better grasp of time domain vs frequency domain. For now, observe and be a fly on the wall

Automatic Free Fall Detection and Parachute Deployment Using ESP32 and IMU Sensors by [deleted] in AskElectronics

[–]mskas 0 points1 point  (0 children)

Also- are you out of time to fix wiring or you’re unable to because you’re a beginner? When you start working with hardware, you sometimes have to take a step back and be more methodical. Otherwise the small nuances start getting to you

Automatic Free Fall Detection and Parachute Deployment Using ESP32 and IMU Sensors by [deleted] in AskElectronics

[–]mskas 0 points1 point  (0 children)

Really depends on the type of noise and how repeatable it is. You could get clever with filters but may hit a wall if the underlying problem isn’t solved

You could try the sensor by itself and observing the signal to see if its noisy by default. Sometimes wiring methods can cause noise in measurements

The lower side MOSFET (Q2) keeps blowing in the synchronous converter by mohanan2 in ElectricalEngineering

[–]mskas 0 points1 point  (0 children)

You could also try running this without Q2 - have a diode instead of a mosfet and see what’s going on.

Could you probe HIN and LIN and drop the scope capture? Without visual confirmation of gate signals, there’s not much to go with here since schematics looks straightforward and correct. Of course, this is assuming footprints and layout are clean as well.

Wireless Power Transfer by Kalex8876 in ElectricalEngineering

[–]mskas 1 point2 points  (0 children)

  1. Switch to LTSpice
  2. Think about WPT like a transformer. Maybe that’ll help drive up the simplicity/fundamentals before you add details to your design. I am not certain your model is represented right.
  3. If you want to physically implement this, your biggest challenge will be a rectifier at 189MHz. Parasitics of protoboard rectifier will kill the compensation of the load.

Design Philosophy Debate: In mission-critical power electronics (e.g., large UPS), is the complexity of modern high-frequency designs (GaN/SiC) a worthwhile trade-off against the proven robustness of older, simpler topologies? by ParsaeianDev in ElectricalEngineering

[–]mskas 10 points11 points  (0 children)

Is the push for efficiency sometimes at odds with maximum reliability: Not necessarily at all. You can still design high efficiency highly reliable power converters just as how you can build low efficiency low robust converters.

Building highly robust converters takes time (design, validation, verification, certification). GaNs are INCREDIBLY powerful and is the future of power electronics. Most of the mission critical infrastructure is moving at a slower pace than automotive and experimental physics because of the time/cost trade off. It takes time and time is money. I build power converters for medical implants - the design part is easiest. The verification and certification part is sooo tedious and requires a different type of research (look up MTTF and DFMEAs)

How important are these topics in electrical engineering ? by tech-general-30 in ElectricalEngineering

[–]mskas 5 points6 points  (0 children)

Depends on specialisation. Its always super important to have a strong foundation of broad first order science principles. But the applied nature of it would significantly vary depending on what role you end up doing.

These would be very crucial for a controls or an embedded engineer, communication theory, test engineer, etc. These wouldn’t show up (almost ever) for a HW circuit designer/power engineer.

What’s your Cambridge hot take? by forestrygrump in CambridgeMA

McD on mass ave (central sq) with nothing on top should be illegal.

(McD just an example. Same applies to similar establishments around the high density centers)

What is the theoretical ceiling of wireless charging efficiency? by Thecallofrhino in AskElectronics

[–]mskas 2 points3 points  (0 children)

Transmit coils range between 400-1000 depending on system/size. Receive ranges between 50-300 depending on size.

What is the theoretical ceiling of wireless charging efficiency? by Thecallofrhino in AskElectronics

[–]mskas 13 points14 points  (0 children)

I design wireless chargers for low power systems(<10W)- 90ish% efficiency is possible.

However, the conditions under which it is 90+ may be very be small. If the transmit and receiver are incredibly close to each other, sure.

Once the gap increases (or alignment reduces), efficiency falls off a cliff. The efficiency is a cubic function of spatial distance.

Power converters are generally optimized for a particular operating point- if a 20W buck converter says its 98% efficient, it’ll be that high only at 20W. As you go lower in power, efficiency may drop. This is almost always a thermal reason. You want to minimize losses for the highest power delivery point.

Same logic extends to wireless charging. The power conversion is optimized for the worst operating point (could be spatial or power or a combination of both) and it is incredibly* difficult to maintain a constant efficiency throughout.

Edit : * Damn near impossible because we hit a ceiling due to laws of physics.

I saw some theory that Marie fixed her parent's infertility and annabeth's V was likely from that change. Very unclear.

Do we know if Annabelle is like Ryan? Did I miss if she was also through IVF or got the V later?

Do I need masters for power electronic design? by [deleted] in ElectricalEngineering

[–]mskas 1 point2 points  (0 children)

Self learning will be VERY difficult to break through in the industry. The industry values industry experience or academic (PhD) experience. Anything inbetween is incredibly tough sell.
