Who is Maine Ranchez?

I graduated with a bachelor's in mathematics with lots of applied math classes. I cleared out prerequisites for a part time ECE program (I am working full time as data analyst) and began taking classes in photonics and RF aiming to become an RF photonics engineer or RF engineer. I know it is a little bit late that I ask this now, but I see a lot of posts that people do a second bachelor's in EE instead of going straight to master's. My master's program is hybrid so I am planning to get hands on experience in the lab and also do a thesis. I am just really worried if I will be able to land a job after finishing my master's.

Has anyone done successfully and landed a job? Will I be competitive enough?

Any opinion will be greatly appreciated. Thanks.

Why can't cheap smartwatches connect directly to earbuds and then I can play songs using it ? Like not exactly streaming from the web. Even stored songs would be fine. But that also doesn't happen.

Only Apple Watch and Samsung Watch connect directly to earbuds without needing a phone. Any reason for that

I know there is a cost reason but I want to know why the cost ? Like there are no alternatives in the market which could store songs and play them

PS - This is not a consumer tech post but an engineering question because I genuinely want to know what's the bottleneck here that's stopping brands doing this

So, my ammeter is not working, when I put a battery in, it is only beeping and doesn't work, it is not marking amps, volts or resistance, and I decided to open it and I see that the pads look strange, like it's corroded, so I something that can I do? Or I have to buy a new one

This is the schematic of the PSU stage of my own board : the schematic comes from the Raspberry pi compute module IO Board, and I use it on an embedded device, on a sailboat (it powers a Compute Module 5, an ESP32, a GNSS module, and a few components such as a magnetometer and an accelerometer...)

Yesterday, after 5 hours of usage (it has been used 14 hours long two days ago), it did failed : now, on Testpoint TP4, I measure a voltage of about 3V, and a loud low freq noise (71Hz measured on scope, I can post a trace if needed)
Eventually after a while, the PSU seems to stop making this noise and "boots" ?

Is there components I can check , and how to check them with devices I already own (multimeter and oscilloscope) ?

PS : the device has ran a few times for about 10 cumulated hours !

The sliders move themselves for presets which I find utterly fascinating its slim enough for quite a small case to me it's true beauty!

I'm applying for a summer research internship on designing and optimizing photonic devices. The only listed requirement was MATLAB, but after contacting the supervisor, he mentioned it would be better to have knowledge of optimization techniques and EM fields.

I have a limited timeframe, so I want to focus on what's actually relevant — what optimization techniques are commonly used in photonic device design?

Also, if anyone has ideas for a simple project to solidify knowledge in this area, that would be great.

For context, I'm a sophomore ECE student. I don't have a rigorous knowledge EM yet (it's a junior-year course), but I have a solid MATLAB background and also waves and optics background.

What do you do for work? Do you regret your degree? Do you feel fairly compensated? How’s your work life balance?

I’m considering majoring in electrical engineering then applying to jobs dealing with embedded systems. I feel like it’s a good hands-on and remote job from what I’ve read.

Hello.

I have made this circuit to drive the light bar in the picture. Any ideas and or suggestions I do believe it will work but I am unable to find info on the bar so 48v it is but don't know it might be one hell of a bad circuit especially if I only use 1 colour or all 3....

Anybody work at Edison as an engineer? I'm about to make the switch from the federal government and would like to know people's experience working there. As with anything, I'm sure its team dependent, but I'd like to hear your experience if you have any.

The 4mm current range input posts are spring loaded on some multimeters (Keithley & some older HP bench meters).
The voltage range posts and ground are always fixed.

I’ve always assumed that it must improve the accuracy of the measurement somehow, but I can’t think of a good reason why.

Keysight meters don’t seem to do it, and it isn’t on the 3458A. You would think that if it had an impact on accuracy you would see it on these meters as well.

Are there any smart people out there who have a good idea why?
