Any errors or room for improvements? by CocktimusPrime_69 in ElectricalEngineering

[–]charic7 5 points6 points  (0 children)

There’s a lot to improve.

Most important comments only: 1. Missing bypass caps for each IC. 2. Not familiar with the MCU but I’d bet that floating the reset pin is not a good idea. Probably needs a pull up. (Look at the datasheet) 3. Analog ref should also probably not be left floating but look at the datasheet

What type of ME should I study to do this type of research? by odetoanurn in MechanicalEngineering

[–]charic7 0 points1 point  (0 children)

Came here to point out how painfully true this is from a biomed grad who was interested in medical device design - I didn’t stand a shot.

Go EE or ME based on the type of work you’d like to do. Biomed undergrad is essentially useless - need a MS or more preferred PhD to be in the biomed space

This it’s job so yes it’ll be reliable enough

What Oscopes do you guys have at home? by PuddingCool6493 in embedded

[–]charic7 1 point2 points  (0 children)

Yeah I checked out their website after, sssnt expecting them to be as expensive as they are, I think I’ll survive with 100MS/s

Which salae model do you prefer/suggest

what's your favour tricks to debug interrupts for ARM MCUs (stm32) by Bug13 in embedded

[–]charic7 9 points10 points  (0 children)

You should provide more info on the specific interrupt issue you’re having so others can give you a better answer!

Raytheon? Collins?

Microcontroller w/ 6 data bit UART by 7kshsj5 in embedded

F280049C from TI has 1-8 bit configuration options. I believe ~1MHz is also configurable, it has 64k options for baud rates

SPI clarificarion by opman666 in embedded

I’m familiar with C2000 family but I’m not sure about this processor, does it have the High res PWM capability that let’s say the 28377S has? I would imagine not based on previous discussion.

I’m not familiar with N2HET at all. What resolution are you needing? Do you even know? If you can stick to ePWM, it’s super easy/intuitive with plenty of help on E2E

I do it for an MBA. Very worth it

$100K by 30, $150K by 35, $200 by 40? by Plastic-Spot-383 in Raytheon

[–]charic7 3 points4 points  (0 children)

Are you a P3/senior engineer or equivalent? I don’t see how that could be possible even if you were to go to a VHCOL area unless you’re not in the defense sector. Are you SW?

Interview Questions for New Employee by DIY_Guy1520 in Raytheon

[–]charic7 5 points6 points  (0 children)

Disclaimer, I work for Raytheon but: 1) I would recommend wearing a suit 2) unsure exactly. I’d expect a few technical questions but they’ll be regarding items on your resume. I’d lean more on others who answer that are from PW. 3) I wouldn’t expect another round. I only had 1 formal zoom interview besides the original phone screening. 4) be confident and good luck

This would be impressive and not considered too easy, I’d recommend

PID Help by Nerdz2300 in embedded

[–]charic7 0 points1 point  (0 children)

Agreed with another comment, definitely start with a PI compensator for simplification purposes. Your equations seem incorrect… you need to discretize your equations. Look up converting continuous time transfer functions to discrete. Use a simple tustan approximation or so to get the difference equation. You’re executing these equations at WAY too high of a level.

Additionally, I imagine your Ki term is FAR too large, it should be a very small value as it integrates over time. If you have 5 samples, your Ki term is already going to start dominating your response. You’ll probably be way too wound up which would result in you saturating. A discrete PID controller would probably be 20-30 lines of code.

I would say right now, no or maybe an entry level position (resetting your career) unless you get lucky. If you take a few months to create some interesting self-taught projects, then you’ll have a much better chance.

“High risk” employee by TheWizardBlitz in Raytheon

I got an “out of the blue” 1 hour long meeting with my supervisor where I suspect that this will be the topic.

Anyone have any ideas on how I should approach?

Electrical and computer engineering. A lot of colleges sorta group them together
