I made a CAD software for designing electrical control panels

Hello everyone!

I've been working on a personal project for a while called Panel Master, an affordable CAD software for designing electrical control panels.

https://panelmaster.app/

It allows you to design component layouts using real-world dimensions, make changes very quickly, and generate technical documentation in PDF. You can also export designs as SVG to use in other programs, and generate DXF files with cutting lines for machining mounting holes.

It comes with a fairly extensive library of generic components, and I'd love to add more based on the needs of the people who use it.

I'd love to hear your thoughts and any feedback you might have!

Difference in total solar production between our system and the electric company?

Sorry for the long post- I’m just pissed and (I think) there are important pieces.

TLDR; How much electricity is lost between the solar panel micro inverter and the meter? The total production the electric company reports (before usage is considered) is significantly less than what our system reports. Why?

Ok. I’m hoping it’s ok to ask here, but I can’t post in r/askengineer because I don’t have enough posts in the community or something? Idk. Anyway- I have been tracking my solar production because, first of all I love analytics, but more importantly, I think our electric company is ripping us off (PECO). We run on their net metering program, so we get a report of our usage, production, and excess on every bill. By my count, they are only counting about 63% or so of our production for credit towards our bills each year, and have been shorting us for over 2 years. I will attach pictures of the July ‘24 bill, production for the matching dates as reported by our system, and the production counted for SRECs. Obviously, the SREC count won’t match exactly, but it gives a general estimate because June, July, and August ‘24 are similar.

Important note: I am using 2024 instead of 2025, or more recent months because we haven’t had a real bill since the July ‘25 bill, and ‘24 gives the best comparison to the SREC numbers. They are just now sending out OVER A YEAR worth of bills (after several calls and three requests for a manager) so I don’t trust a damn thing they say. The 63% calculation still stands for 2025 and 2024 (as far as I can see from what they’ve sent me) so the comparison is still accurate.

Anyway. How do I reconcile 1.2MWh of production as reported by my system, and 623kWh production as reported by PECO (51.9% of what we produced at the panel)? Am I stupid, or are they shorting us?

Nixie tubes and clocks

Hey guys,

I'm planning on building a nixie clock, but I'm afraid of the lifetime of the tubes. I'm thinking about buying IN-8 tubes, and I found that they usually last 5-10k hours. Which is pretty short imo.

Do you have any tips? Should I choose other types of tubes? Or am I wrong about the lifetime?

Thank you!

My career is not progressing as I thought it would. I need some advice.

I graduated with my Bachelors in EE in December of 2024. For about a year after graduation, I was studying for my NERC RC exam, which I failed with a 66% in September 2025. After taking the exam I applied for 100+ jobs before I was finally hired as a Distribution Technician in March 2026. The Technician job was a contract job that was supposed to last until December 2026, but I was blindsided this past Monday by being let go. Ive applied for 10+ jobs since Tuesday. I see all of these engineering jobs, even entry level ones that require 0 years of experience require experience in all of these CAD software's (AutoCAD 3D electrical, Revit, Microstation, PLSS-CAD, PLSS-Tower, etc). When I look on these CAD companies websites to see how much they cost for a subscription to try and self teach, they cost thousands of dollars to subscribe too. My university never offered any classes that I can think of that taught you how to use the CAD programs. How am I supposed to learn and gain experience with these programs if I can't get an entry level job that is willing to teach me how to use it, or pay a reasonable price for a subscription to try and teach myself? I want to work in the Power industry, but I'm also open to manufacturing engineering (especially for electric vehicles), and engineering jobs in the defense industry. I'm worried going back to school for a masters might be my only option, but I dred the thought of having to go through engineering school again as I was only an average student. Any advice is much appreciated. Thank you!

Chapter 2, a home theatre, 3D printed parts, motorized projector, home decoration, and DIY electronics -- I spent alot of time figuring out how to control different actuators and such via microcontroller to control the tilt, roll, pitch, and translation of a projector. If you know of anyone else that might be interested in this stuff, sharing to others would really help me out! Hope to see you around here or YouTube :)

Beginning the journey!

Hello y’all!

I’m a student looking for fun hobby-projects. I am currently in college and have been programming for about 4 years now. I begin to see lots of cool projects on instagram and want to make my own.

Specifically, i found this project which is mainly software but also a good start of understanding serialbusses and matrix-display handling: https://www.instagram.com/reel/DcR9UnTisa7/?stkn=MXR6OHRiMDh2dG8zNw==

I want to know, which components i need and what you’d buy if you were me. I would rather not spend too much money, but hit me with the expensive parts if it is a good value.

Furthermore, any tips is appreciated to avoid the most annoying beginning mistakes, but don’t ruin important learning steps if any!

Thanks!

What happens if you touch a 600v dc rail?

I've been working on subway lines recently, and the third rail is 600v live. I'm not sure of the amperage but I imagine it's around 1k amps (could be wrong lmk) and I saw a few posts on here with mixed opinions on what would actually happen if I touched it while working around it? Realistically, I would have gloves on and arc flash gear. What would happen if I just grazed it with my hand?.

Is grad school for EE worth it?

Hey everyone

I graduated with a B.S. in Electrical Engineering this past August and recently started a full-time engineering role through a rotational program. Since starting, I've realized that the areas I'm most interested in are the hardware side of RF, communications, and also DSP. I took an RF course in undergrad and was exposed to communications and DSP through my senior capstone project, but I don't have much formal coursework in those areas.

Looking back, if I had taken some of my senior-level EE electives before accepting my job offer, I probably would have pursued a different path. My current role is in a different area of EE, and I'm concerned that the longer I stay away from RF/communications, the harder it may be to transition into those fields later.

I've been considering pursuing a part-time research-based M.S. in EE while continuing to work full-time. My employer offers tuition assistance, and I've found several professors whose research aligns closely with my interests in RF, communications, radar, and related areas.

For those working in RF, communications, DSP, or defense:

  1. Is an M.S. necessary to break into these fields, or is a B.S. typically sufficient?
  2. Would self-study, projects, and work experience be enough to transition, or does a master's significantly improve career opportunities?
  3. For those who completed an M.S. in EE, was it worth it? How valuable was a research-based master's if your goal was industry rather than academia?

I'd appreciate any advice from people who have been in a similar situation.
