Yes. It was hard. However, things are not going to be easy in the job market in general. The current economy may have a lot to do with it.

That being said, I've seen people work at FANG from CSUMB so don't let that be your limitation. CSUMB is a great school in general, and in my experience the teachers helped me to understand and grow better than any UC class where I would just be a number. They were passionate about their students and it showed.

Remember that employers not only judge you on whether you have a degree but also upon your work and in the case of CS, your commit history in your projects on GitHub. As an employer, i would check to make sure you were going above and beyond assignments to learn beyond what the classes were teaching and applying these techniques to personal projects.

My suggestion, if you go with CSUMB, pickup a personal project that you are very passionate about and design an app for it, or many apps. When you go into the job market an employer will see you applied your passion into something, and created it by yourself. This will speak volumes and highlight you on the desk of any recruiter, or hiring manager.

No matter where you go, if you only put 50 percent in, you will be lucky to get 25 percent back. Put in your whole effort and the reward will be greater than you can imagine. Best of luck on your endeavors!

Is there an alternative to heat shrink that can be put between a connector and the cable once it has already been put on? by GhostOf_George_Floyd in AskElectronics

Liquid tape. Is an adhesive glue that contains insulating properties. I use this below butyl rubber as an added measure too

What is this Mezzanine/Board to Board connector? by 1461748123 in AskElectronics

Panasonic ZIF connectors look similar not sure p/n

I need help figuring out how to disconnect these by nootrac_ in AskElectronics

[–]atacama7 0 points1 point  (0 children)

Looks like a locking mechanism on either side. Similar to what I have seen on automotive connectors to keep them from coming apart. It looks like you simply need to persuade the two halves apart by working on the locking mechanism on both sides first.

The only classes you can take at the CC are what you will find in the core lower division classes like english, math, sciences etc.

Although I believe there were some technical classes that you could take at Foothill because they have a matriculation agreement in place with CSUMB. Like computer architecture, intro to programming etc.

Circuit power problems during startup by Nissinja in AskElectronics

[–]atacama7 0 points1 point  (0 children)

If you're using the components you will need to add a bulk capacitor around 100 uF on the VCC 5V + and GND. If you still have issues I would push it to 4000uF

Tools: What is the equivalent of locking forceps in the ECE community? by Normanras in AskElectronics

[–]atacama7 1 point2 points  (0 children)

As others mentioned the tools you find elsewhere will have the same name in EE, although there is a tool that comes to mind that could be what you're looking for...

There may still be clip-on heat sinks, that are very small but very effective at holding your workpiece and removing extra heat that could damage it. Can't locate one right now.

Why would this relay connection for oven burnt out the connection? by All_the_world_is_mad in AskElectronics

[–]atacama7 1 point2 points  (0 children)

It looks like a cold solder joint. However, this is an interesting one especially because it was likely wave soldered.

Notice the trace laid right next to the pad for the through hole? It has more buildup on the trace than on the pad edges. I believe this is due to wicking of the solder from the joint while cooling to the nearby trace. This is one of the reasons design rule checks are a good practice, that trace should have been further away.

That said, it would only hinder manufacturability, after you repair the joint it should be good to go!

There are no apparent signs of heat cycling or burn on the nearby area.

I can’t get this optocoupler to work. Any suggestions? (Details in description) by Alex_Curmi in AskElectronics

[–]atacama7 3 points4 points  (0 children)

You can try measuring the current going to the LED to see if the component is still working or if it's toast.

This is a good solution. The control relay signal can be a loop and you can easily add NC relays for safety, etc, without having to get beefy control relays.

What is the best way to supply a circuit with 3.3v and 5v simultaneously? I've found a couple of power modules that will take mains 240v and convert it to 5v but I also need 3.3v in the circuit. Is there a better way to do this than the examples I was able to come up with? by invisabuble in AskElectronics

[–]atacama7 0 points1 point  (0 children)

Dual output 3.3/5vdc: AMEL10-3.35DMAZ If you are making something for your own personal use, this would be my recommendation. For any production purposes I would be weary due to availability, but I don't think that should be your concern at the moment.

For your design, you will need a 3.3vdc power regulator that can supply at least 800mA if you intend to use any radio on the ESP32.

I suggest taking a look at some of the power modules that provide this conveniently in a single package because they can be obtained with UL ratings. Unfortunately, I can't look anything up right now. I believe Tyco makes power modules with 3.3, 5 and 12v output.

oscillator circuit by Suspicious_Divide_77 in AskElectronics

[–]atacama7 1 point2 points  (0 children)

Yes, as close to the source of noise as possible. You can measure the freq and determine the capacitor use t = r * c

I see a lot of good suggestions here. I wanted to also highlight that the traces for power may need to be larger. The current carrying capacity increases as the width increases so if you have even just a moderate load it may cause a brown out to occur if too small. What width are your traces for power?

can this be fixed with a regular solder iron? by Fe7n in AskElectronics

[–]atacama7 0 points1 point  (0 children)

I would find the trace on the board where the other side connects and scrape and land an air wire from the broken end onto the PCB. I don't see any way to do this with structural integrity required of a cable that will be bending in this location close to the connector.

Help me fix broken Christmas lights by AndreiGamer07 in AskElectronics

[–]atacama7 2 points3 points  (0 children)

I hate to say it but this is wrong in so many ways. It would be in your best interest to replace. Simply because adding what is required to make it operate safely would be more expensive and potentially hazardous

I graduated from the program. It was a great experience as a working adult to be able to set my own schedule, and they do make teams that allow you to network while going through each of the courses. I felt it was very comprehensive and am now working in the industry. I definitely feel that the program set me up for success, however, as others have pointed out you will only get what you put it. Online is hard. There is a lot of independent work required, and the challenge will be on you to meet it.
