Having 16gb of ram means I have no motivation to ever close anything. I would have 9 more Excel windows open if I didn’t get an error because they had the same names as the ones I was trying to open. This is one project, it gets way worse when I am switching between doing multiple things.

You should be able to open more than one Excel sheet with the same name, as long they aren’t actually the same file.
You need to open a new Excel process first though. Middle click the Excel icon on the taskbar and you should be good to go

What kind of circuit are you building? Looks like some sort of filtering or soft clipping thing?

I had already gotten what I needed out of the first set of files so I just closed them when it gave me the error.

As much as I’m not a fan of Mac (but I’m forced to work on them at work) they have this figured out pretty cool.
I can make endless desktops to jump between with a shortcut...per screen. As an example I just made 6 for my main screen, this doesn’t count the “7th desktop” on my external monitor.

This is a lab report on diode switching as well as clipping and clamping circuits. Boring grunt work when you are designing circuits like this in your spare time:

So funny. In the 90s, this was the complaint of so many Mac folks about having to work with Windows.

Time for more monitors.
I have 3 42" side-by-side TVs for mine, and I’m contemplating adding another row on top depending on Black Friday prices.

nice, what is it all doing? looks like maybe a charge controller? I see CAN chips so looks like its in a car. How are the atmega chips to work with CAN? I’ve used those MCP2551 chips with a PIC18 for CAN, and it took a bit of playing to get it working right. Ever work with DC/DC converters?

Ha, in my industry it’s always been VERY Mac based. I’m in advertising and was the ONE guy who would show up through out college with a PC running the full Adobe Suite. They all looked at me like I was insane. I looked at them as if THEY were insane because my $1,000 laptop was faster than their $2,500 laptop in the same exact programs.
2 years after graduating I took the flash project I was developing for Ford home and did it on my home windows laptop (which was 6 years old at this point) because my agency Mac crashed every time I opened the file!

Meanwhile in my neck of the woods:
46 GB of 128 GB used on my compute machine. On my main W10 workstation I have 64 GB on my workstation. Right now I’m using 15.3. There’s been times that I’ve maxed it out and had to close some things (like 100+ Chrome tabs), but I haven’t felt the need for 128 just yet. Less than 32 and I’d have a panic attack, though.

It’s monitoring a 12V lead acid battery usning a TI BQ34z100PWR gas gauging chip communicated to over I2C, controlling charge into the battery from a DC/DC converter in a 108V nominal battery pack constructed with 34 LiFePO4 cells, controlling the distribution of all the 12V power through the entire car with 4 PWM controllable supplies, 4 digital supplies, and 8 fixed supplies, and receiving information on pedal status and dash switch status over CAN while transmitting the Voltage, Current, state of charge, and basically everything else you could possibly want to know about the GLV battery back onto CAN. What started out as a design to data log off the low voltage battery quickly evolved into making one board to control all the low voltage systems on the car.
CAN from the Atmel is actually really easy to do. The 2515 allows me to easily communicate through the 2551 using SPI from the Atmel. The Atmel controllers are nice because you can use the Arduino IDE to program them which gives you access to all the libraries available to the platform. From there it’s just simple library functions.
The BQ34Z100 on the other hand is a total PITA to work with because it is intended for mass production uses so no hobbyist uses them so there is no library. It uses a ton of funky timing in talking to it with a 8 bit + 16 bit (+ message of various lengths if needed) communication requirement. It was a pita to get the 8-bit atmel to fake 16 bit I2C well enough to convince the BQ34Z100 that it was actual 16 bit. And of course none of the funky timing requirements were noted in the datasheet so I was flying blind trying to figure out how to get it to work in my prototyping over the summer.

Originally, Adobe was Mac only or Mac first, but that changed in the 90s, and they really became more interested in Windows. I think platform parity hasn’t been an issue for decades, but OS preference always is.

My problem was never memory. My problem was 1) using a laptop and 2) that Excel uses the first core primarily (i5 3rd gen), which slows down the calcs on a 40GB spreadsheet. I had to turn off all non-essential functions and buy a cooling pad for my laptop to keep my sheets from crashing.
I’ve since broken down my sheets to 10GB files and upgraded laptops.

I don’t really use excel for much. If I have to do heavy number crunching I am usually writing a MATLAB script. This was mostly done for convenience as our oscilloscope software allows us to export the raw data as an excel file.

I look forward to eventually upgrading to 8K monitors/TVs (gotta get that refresh rate amd response time down...). 4K is OK but a little much for PC gaming when it’s so close, and I had notably faster response time (it seemed?) from my 1080p monitors, though those were also only 32".

Sounds like fun. Hopefully you have a good scope. I know that feeling of troubleshooting communication buses, it can feel like banging your head against a wall. Looks like a cool project though. You should post a write up here when you are done!

We have a basic 2-channel Rigol in our shop space which we are working on hacking to unlock all the fancy analysis features we didn’t order when it was new. If I really need fancy equipment I can head upstairs to the EE labs and use one of the fancy pants 4 channel Keysight scopes my school just got. We also have a 8 channel Saleae Logic analyzer which occasionally proves to be useful. It was fun trying to do a bit of prototyping at home over the summer when my only way to have any idea what was happening was to echo the data back to my PC using an Arduino’s serial functionality.

Yep, for me it’s a cost issue. To buy a computer for home to handle this kind of work I want the most bang for my buck. The Mac will NEVER be that.
The Mac people in the advertising industry just refuse to even believe a Windows computer can even RUN Adobe software.

Well, we Mac people can be a pretty rabid bunch of loyalists. Honestly though, when I’ve spec’d out comparable Mac and PC systems from vendors that sell the whole machine, I get comparable prices. There is really no “Mac tax”. The savings on the PC side comes if you customize your own system, which most consumers don’t do. That you can’t do with a Mac, and the price differentials in that case can be big.
One thing you could always count on with Apple was better overall quality than the average PC OEM. However, I have witnessed that lapse in recent years. I had an iMac with two successive hard drive failures, and Apple out of warranty repairs are $$. The second drive I just replaced myself, but the new iMacs are glued together and don’t make that easy. I still think Apple hardware is better than the Dell crap I see around me at work, but it’s not as good as it once was.

When I cost compare I find the Macs at a huge “Mac Tax” price. The problem is that I typically max out the specs on the Mac.
Last time I was shopping for a laptop, I got a bigger screen, better resolution on the screen, and a lot more processing/ram power than the closest Mac in comparison and it was more than $1,500 less.
Sure that laptop was a steal and it HAS been a while. But it’s still kicking.
GLUED TOGETHER?! Come on now that’s just an obvious “how do I fuck over my customer” type of move.

The previous gen iMacs had the glass held on my magnets, and you only needed a plunger to remove it. Screwed over, indeed.
I won’t contradict you on the laptop front. That’s a different beast from desktops, and Apple certainly makes choices that some customers don’t like and would do differently. I switched to iPads for my mobile needs. There is no doubt that you have a wider variety of choices and prices in laptops on the PC side.
