Idk what I did to deserve this look from my cat!!

A big jump in my electronics work came when I lost fear of SMD components and started soldering on breakboard to use them on a breadboard!
Now I have way too many… 😅

So… lately I’ve been getting into understanding the world of finances. So, for whoever is curious but never bothered to look (like me) a basis point = 0.01%
So, if my 7.40% profit margin (I wish!) increases by 30 bps…
7.40 + 0.30 = 7.7%
The more you know! 😁🤷♂️

Order new PCBs…
I gotta say, that not an error I make anymore😅

Uff!
I once designed a pcb with 0402 resistors… later decided that soldering those by hand would be a pain and changed them to 0805.
Turns out updating your BOM doesn’t automagically updates your PCB! Received the PCB with a bunch of unsoldered 0805 on top of 0402 footprints… 🤦♂️😅

When I’m making a struct that contains itself I’m not able to use the typedef, need to use struct foo one;

If you write C and haven’t tried Meson… you are in for a treat!
It is (for me) a lot more approachable than CMake, stellar documentation, and the files are pretty (for some reason my brain likes pretty files 🤩)
Also, no $@%^ from Makefiles!

I’d be terrified of bending the blade of the $100 one tho! 😅
How would I know if they don’t bend unless I test it? And what if I damage them in the testing? Uff… it scares me

A bit ago… but some time ago I had tons of fun making a CHIP8 emulator in C! If you are looking for a fun project I 100% recommend it!

I’ve been avoiding it for quite a while too… using opencm3 makes it A LOT better for me than with CubeMX…

Hey,
you know that propane torch you use for heat shrink tube and stuff? Put some butter and sugar on a biscuit and blast it with fire! You are welcome!
PS. Make sure is propane or some non-toxic gas!! Although if you have a torch hanging around you probably know your way around not dying!

Anybody else here writing (and loving!) C?
Yes, I’m aware of the rough edges and security issues, but for software for my own usage I haven’t found anything better and more enjoyable to use!
