Comment	Post #286678	Not sure about your JIS transistor letter designations. I remember them differently and this forum posts matches my memory. It was the last comment of 4 in the thread. https://www.badcaps.net/forum/showthread.php?t=11318 (more)	—	about 2 years ago
Comment	Post #286938	Mobile phones have used 2.5mm and 3.5mm headphone sockets and also headset sockets. The headsets usually make provision for barrel, tip and TWO ring contact. The connection arrangement differs between the old Apple phones and the typical Nokia/Android types and many laptops also support a headset s... (more)	—	about 2 years ago
Comment	Post #287027	Unless your electrodes are inert you may be adding some fixed potential due to electrochemical effects. (more)	—	about 2 years ago
Comment	Post #286470	I reply to your comment here to let you know that I would simply have given it an upvote as your comment could have been avoided by the same mechanism to show that you thought it was an interesting idea. The upvote only is like Youtube these days and smacks of censorship (which is why YouTube implem... (more)	—	over 2 years ago
Comment	Post #286470	.... Random internet stranger came here for information as a result of text search, not for protocol or to make nice with the regulars. The more he finds ANY information, the more likely he may stay. The easier he can share even a tiny bit of information that he can the more likely he is going to ... (more)	—	over 2 years ago
Comment	Post #286470	I read all the answers and comments before I engage. I see no point in repeating something that may already be in an answer or previous comment that would be wasting everyone's time so I cannot leave comments unexpanded. So all top level comments may as well be expanded unless there are really lots ... (more)	—	over 2 years ago

Answer	—	A: PCB ground planes with isolated voltage This isn't a direct answer to your questions, but you should be aware of that to maintaining isolation means careful design off the PCB as well. You would do well to remember that if you are planning to have two isolated grounds you have to arrange everything so that the isolated grounds (or their... (more)	—	over 2 years ago
Comment	Post #286470	"Resisted adding votes to comments". Perhaps something less digital would work that is generated by thumbs up or down but only results in a logarithmic indication by way of a single arrow head that is as high as the number of bits used to store the vote count. 16 votes would be a 4 pixel high arrow...

Comment	Post #286477	I am triggered whenever there is talk about deleting stuff. Disk space is cheap, making stuff that is 'evil/unwelcome' hard to find is a tolerable compromise but only illegal stuff should be deleted. I appreciate the 1000 character limit of a comment but having it considered a nuisance is rather hars... (more)	—	over 2 years ago
Comment	Post #286470	I accept the motivation but it makes this site more sterile. A Q&A becomes the domain of the OP and any who answer and nobody else who has something else to contribute does not bother to weigh in. I expect I would learn to ignore the issues I bump into here if I spent regular time here. SE soured ... (more)	—	over 2 years ago

Question	—	Easy way to convert over long comment into an answer Easy way to convert over long comment into an answer. It would be great if while typing a quick comment to a question you realise that you are about to exceed the character count and it is a valid answer to the question then simply clicking the Convert to Answer button would make for a lot of answ...

Answer	—	A: How do PLCs normally measure 4-20mA current loops? You can predictably generate a voltage with a R-2R ladder or a Rn^2 selector and then use a commodity V-I industrial converter interface to generate the current loop the customer desires. You cannot make assumptions of the shunt resistance that the receiver will present, it may not even be purely... (more)	—	over 2 years ago

Question	—	Wish to have comment votes Every time I visit Codicact I miss the comment voting feature. There is no way to know if some comment is rubbish or a gem because the opinions of others are hidden from future visitors. I wish there was a way to rate/vote on comments. (more)	—	over 2 years ago

Comment	Post #280586	Your only real remedy is to test or research your next microwave purchase. They have various rotation speeds depending on the gear ratio chosen for the synchronous motor. It can vary quite a bit so you may find a suitable speed for your local line frequency when you replace or swap the unit one day... (more)	—	almost 4 years ago

Answer	—	A: BLDC motor - initial rotor position In the case of a permanent magnet motor, as found in many smaller drone motors, I have seen controllers merely activate the drive at some phase angle that has maximum theoretical torque (two high, one low or one high, one low and one floating, dunno) and pause for a brief moment for the motor to sett...

Comment	Post #279099	A simple down vote could implement the hide filter. That way the question could remain hidden from those that choose not to follow negative questions until it has improved enough to reach a positive vote value. I fail to understand why OP and I have to be inconvenienced by a close when a down vote w... (more)	—	about 4 years ago
Comment	Post #278860	@Nick I know it has been discussed before, however the solution is not fair. If you think this site is made for the glory of us answering folk then I think I may be in the wrong place. I am here because I like to share information, not because I want to bully new users to ramp up to high standard q... (more)	—	about 4 years ago

Question	—	Please find other ways to hide inloved questions that prompt close I have not been present in the hard and very productive work performed by what must now be a pretty spectacular team for the last 10 months. Having returned and found my cherished Electrical Engineering remade with nicer rules I feel blessed. I have boycotted the SE and neither asked or answered ... (more)	—	about 4 years ago
Comment	Post #277550	I concur with this. In some designs it might also be there to turn the LED off faster (high speed signalling or sensing) for instance if this was a row of LEDs on a optical safety curtain it might be designed to make sure all but one LED was off as the curtain was scanned.

Comment	Post #278860	No they will not. They will leave if they are materially inconvenienced. Seeing a question is not an inconvenience and if we make a feature for those who are afraid of peripheral questions and bad questions they can choose to hide a question. Just like that with a single click they are spared from... (more)	—	about 4 years ago
