The black one is a tantalum capacitor. There are various weird ways to mark these (because typing out 100u instead of 100- would be too easy...). If I'm correct in this case, I believe: 100 stan...
Problem description & speculation about causes I've having a problem with MAX485 transceivers breaking intermittently, passing our production tests but later failing. The error phenomenon is w...
I'm working on another project with extreme EMC requirements as per various notorious military EMC standards. Civilian product but for military use, and as such subject to the toughest levels of co...
I've done similar things on UART lines, but for significantly lower baudrates (9600 etc) than traditionally used on most CAN buses. It's also easier to do when you have 5V guaranteed to be well-ov...
It depends on how you define "battery". I guess the definition is different depending on if you are a chemist, an engineer or a consumer. When electrical engineers speak of batteries, they typicall...
The reason I left that comment is because determining the quality of a coaxial cable involves electrical engineering more so than an electrician, let alone some DIY. The rule of thumb "would you a...
The main problem with a question along the lines of "how do you design a product for medical applications" is that it's way too broad. You cannot reasonably write a somewhat complete answer because...
Draft for a tag creation/deletion criteria A tag must fulfill all of the below requirements or it may get renamed or deleted: A tag must be named appropriately, considering Tag naming guideline...
Additions: Do not use company names in tags. Questions should be about specific products, not about companies. Furthermore, silicon companies merge/split and purchase each other all the time, ...
Because of recent discussions regarding whether vague terms like voltage and ground should be valid tag names or not, it is clear that we have no consistent rules here. These terms are about on-top...
Breakpoints are beyond the scope of the C language, so this is up to the specific debugger and CPU core. What you will probably have to do to block accidental breakpoints is to not provide any debu...
A while back someone suggested that we added a section for reviews to the site - How about a new section for code reviews? From that meta thread we gathered that: There seems to be community con...
Apart from correcting capitalization, which is a valid change, I think you are at the same time doing a lot of subjective changes to certain tags and it can get very intrusive on the site. I don't ...
I agree with everything said. I didn't really consider until now that Codidact (unlike Someplace Else) supports case-sensitive tagging. So in addition, perhaps add a note regarding the following: ...
Using voltage as a way of saying "I'm dealing with voltage here" is pointless - most electronics questions do. I think the voltage vs current tags are however relevant in the case when you need to...
Coming from a background of safety-related applications and industrial control systems, with some maritime applications experience, I could offer a few insights. These kind of game controls are li...
Using a P FET for polarity protection like this means that in case you flip + and -, the gate will be inactive, meaning that GND which is now connected to drain will get disconnected - no current w...
The 45° routing makes it easier to route multiple parallel traces across the PCB - I would say that's the main reason why they are so popular. Whereas 90° turns of multiple parallel traces next to ...
Things happening/things we want to happen before main() is called: The code executed before main() is often referred to as "the C runtime (CRT)" or just "start-up code". This code is typically pro...
Whenever declaring a variable in C outside a function at file scope or when specifying it as static, it gets assigned a life time known as static storage duration. Meaning it will be accessible thr...
I support this idea and think that it might fit the Papers category, although it should be allowed to have multiple users maintain and moderate it. It should be a brief glossary for a quick look-up...
At Somewhere Else, we started an initiative to make a community-maintained list of abbreviations used in electrical engineering: What are abbreviations used in electrical engineering? I think it c...
#1 before anything else is to do your homework. The Nordic semi web site says: "nRF24 Series Not recommended for new designs". That means forget about using this part! They are phasing it out of pr...
Based on this nerdy but seemingly trustworthy site: https://www.prc68.com/I/TelephonePoles.shtml Then I would guess these are cable TV repeaters/signal amplifiers. Classic cable TV uses copper co...
