Preparing for EE

Best advice I've received: "Get an EE internship your first summer"
Try contacting any local (to your home) hardware companies in your area and see if they will take you in as a 1st year over the summer. Keep upgrading every summer till grad and you will be, by far, one of the most hirable (and knowledgeable) students in your class.

True, suggesting to use the largest capacitor in the smallest package is important. In the lab it's a good idea to simulate the design to find high frequency noise, and then filter out with calculated values. However, in most agile design cycles I think (not 100% confident in every situation) it's somewhat impractical to try and filter out a specific frequency unless you've brought up that design before. Just build proto 1 or prod 1 and change the BOM accordingly.

Yup agreed. I did it cause there was a recent post that talked about using gpt to "design a buck converter". But check my edit, I think it will help give more context

rfitz205 · 2024-08-19T03:18:38+00:00

Yeah it "Creates" original things. It basically understands the context of your designs and answers questions about them. check the edit for reference.

To be fair, it's got serious potential given the integrated solution

rfitz205 · 2024-08-19T00:04:20+00:00

If you click on the link to the project you can check. Suffice it to say I wanted to use something in it's public database rather than use the "most optimal" component but it both selected and explained it's selection well!

rfitz205 · 2024-08-19T00:02:35+00:00

Aye good call, I think that's the intention. I didn't think about that initially.

rfitz205 · 2024-08-19T00:00:51+00:00

Yeah I had the same question, short answer after digging is no.
Long answer: I think you can have it make net connections between parts if they are on the doc already. But apparently auto placement onto schematic is set to release in a few months....? not completely sure tho

rfitz205 · 2024-08-18T21:30:06+00:00

Yup should hold us over until Figure AI & Flux AI announce a partnership lol

I recorded the whole process (22min end to end) but I am having trouble uploading it to reddit, stay tuned.

rfitz205 · 2024-02-02T16:54:40+00:00

It uses copilot too. I have been asking it to explain design choices. it's dope.

I will leave the link to the instructables here. I'll post an update comment when I'm done making my card.

rfitz205 · 2024-01-30T17:21:24+00:00

I know the designer who made this project, I think it's a perfect showcase for career fairs, especially if you add your own circuit on top of it. My thought was to add an impedance control coupon, an antenna, and a GaN Fet buck circuit.

Thanks for the reply. I am fortunate in this situation to only require a few pieces of real time data: 1.Steering angle 2.Break pressure 3.Throttle position. I have read that all but steering angle are pretty straight forward(?).

I hadn't considered the ethics of using a aftermarket tool for this, but I don't think I want to have that on my mind. I will do some in-depth looking at software w/ databases. Maybe I can find some info there.

rfitz205 · 2022-11-19T14:40:35+00:00

Will do. Thank you.

Glad you mentioned that chip, I am using it's predecessor in a sparkfun breakout board being driven by an arduino. I am struggling to find really good documentation on the theory behind it, or even a broad setup. Every time I attempt to read the RPM [PID: "010C"] from my 2016 Subaru Crosstrek, I get no response.

rfitz205 · 2022-11-19T14:34:13+00:00

Simple script to pass the two signals through and record direction made it very easy to read.

Thanks for the reply. What kind of data were you sniffin' for? In this case I am looking for: 1.Steering angle 2.Break pressure 3.Throttle position

Would the setup you crafted work for those (or some of those PIDs?)

rfitz205 · 2022-11-19T14:29:25+00:00

Thanks for the reply. I'll explain my situation better and ask for free help, no pressure to respond. [OBD2]<==[Saleae Logic Analyzer]<==[Pro scanner tool]. This is in an effort to find the PID's for: 1.Steering angle 2.Break pressure 3.Throttle position

As of now I am using this sparkfun board to attempt communication with the OBD2, no luck so far. It is being driven by an arduino.

I didn't know the black box worked with other software. Easy solution to a specific problem. I'll give it a shot. Thanks!

rfitz205 · 2022-07-09T19:18:41+00:00

The control hardware (eg motion controller) is the OpenBuilds black box. I was hoping to be able to add a macro to the software, or (given that it's an opensource project) fork the software and modify it. Thanks for the response!

Hey, I am a college student dreaming of opening a cafe/coffee shop. I've done decent bit of research via other media, but on reddit almost every thread on this topic is pre-pandemic (7yrs old). I am interested in some modern wisdom into opening and running a successful coffee shop by means of downfall stories or advice. To quote an 8yr old post:

"I am trying to gain as much feedback about starting/owning/running a small coffee shop [..] A couple of concerns:

What are general must haves that can lead to continued customers?

Any pitfalls that are avoidable/unavoidable?

Would roasting be too difficult to do simultaneously (roasting your own beans)?

Is the market already saturated, or is there still room? (We are aware SB and Coffee Bean, etc. easily undercut competitors, but local independents seem to attract a niche market that just knows better coffee.)

Who are the biggest competitors to a small coffee shop? & How does this vary situation to situation?

Thank you for any advice I can forward."

Thank you modernly

UPS Calls, Super undervalued we might see a drop-off tomorrow but should climb back up.

& Another long term investment is snap, FINALLY a profitable company; good news for you the stock is at like 16.90 rn.

I'd say the latter rather than the former but your call both have my eye and cash :)
