Maybe you are interested in some types of videos that are different than mine, right?This video is about a simple tutorial for a building block circuit, no more and no less. If you are interested in it, you will watch it. Simple as that.Elevator pitch? you mean something to make my videos different than other videos? that is a very subjective criteria but I appreciate a suggestion.Thanks for your post.

content: Hello Everyone!!!I hope I'm at the right place here.I'm following the Videos from EEVblog on Youtube for years now. I must say I'm a big fan!(Maybe my girlfriend not so much she complains a lot about the high pitch of Davids Voice)But sometimes I'm missing Videos where David build something. He is also not so into Software Development.So I head the Idea to make a Youtube Chanel a long time ago to fill this hole.Then 3 Month ago I made the Idea reality.https://www.youtube.com/channel/UC0Tx9NaDqI0UxKtv8LRIG8AIts is f*** much work I can say ....Now I have some Videos done and I'm looking for feedback.I can tell for myself there is a lot of room for improvements.But if i would consider everything there would just be no Video .... it would take more time I haveSo I try to make a as good as possible compromise.What do you think?Looking forward to get better.greetingsPatrick

content: Yes, this is the place.And your fast, stop-motion overhead view combined with voice-over and monitor-overlay is quite unique for electronics channels too! Maybe it's just my preference, but if a channel only contains high-speed motion, it may scare some novice hobbyists away.. It's like an information overload, unless you provide links and downloads are provided below the video, so viewers can read something (like schematics) later. Good luck!

I'd be open to modifying the forum to the preferences of those that join. I'd prefer to see discussions related to experimental treatments and correlations of experimental data with predictions, share SPICE models of complete amplifiers and discuss ways to manipulate data using, say Excel.Also, having more than one location on the web where a relatively small group of like minded individuals can discuss topics of extreme, common interest isn't necessarily a "bad' thing. I have capability to provide the forum and decided to do so.

Audio is quite OK to start with. Your accent is not too distracting - and after someone has been watching you for a few minutes, they aren't going to notice it. Your English is pretty good and so far is easily understandable.As for your aspirations, you seem well aware of how good/bad things may start out ... and that time will be a factor.All in all, it seems you have a realistic outlook on the process, so we are interested to see what material you bring to the world.(and Youtube link in the signature is quite OK)

As they are the wrong value I would certainly change those large capacitors but I might also be tempted to try flattening out those two tagboards. Steam them for a while then apply lots of pressure and they should end up nice and flat.It's obvious that you know your stuff though. Anyone who can identify the age of an amp by the position of the knob lock screws is probably worth listening to

So those capacitors have to go.The steam trick you mentioned will most likely help repair the board to a flat state. Thanks for sharing that. A problem is it is already cracked and may become separated. Going to have to look it over real good.QuoteWhat a very nice comment to say.Thank you.But it is probably just from being around the stuff for 40 years.The owner gave the green light to go with the repair this morning.

content: Optical sensor is a liner photodiode array. 4 large area photodiodes in a line, so that you can get a linear image, and then sense direction by looking at the edges moving along the array. The mirrors in the top are there to get an optical path for focus, and the IR LED will be running at a very low duty cycle ( likely 0.5% on, but 1A of current when on) to get a reflection and good signal to noise ratio out of the photodiode, plus there is likely a connection to the processor that allows it to use synchronous rectification to recover the data with lower noise.VLSI mask processor is likely a custom chip, with some analogue processing on board to handle the 8 analogue inputs, and then a simple low resolution ADC to get digital data. which is then sent out as raw data with the sync byte.Hitachi looking logo is a fiducial marker, used by the pick and placer to get the relative locations on the board to insert the components in off the tape reel. Trace stubs were likely an accident in manual trace layout, and are not anything to worry about. Likely the original artwork should have had the trace removed, but those were most likely originally placed first run through, and removal would have disturbed later added layers of tape and film, so they just were cut short.Almost sure that mouse would run with an older Linux kernel, providing you have a PC with a real serial port on it.

The intention was to pick a free theme with a dark background, but the current one is not too good. I will search for other themes and try them too. Unfortunately, the blog is hosted with a free plan on wordpress.com, so it does not allow too much configuration. Even if it does, I don't have enough wordpress skills yet.The rest of the observations are very helpful too, and I think most of them can be implemented.Thank you very much for your time and advice.

content: Seriously, the graphics are rather meh...Blender can render much better than that, and poor color choices sometimes cause contrast issues. (Probably due to time constraints they went with lower quality that is faster to render.)The number of rendered frames are not a measure about visual quality or good presentation.(A bit nitpicking: the speaking voice makes it difficult to sit through this video. Also, the happy smiling atoms which hold hands with each other makes me think this is being aimed at small children. Is this video really aimed at small children?)In contrast, here is a video showing the basic working principle of a BJT (although its focus is different from LE's video) while -in my opinion- delivering much better graphics and much better presentation:(The video i linked is not free of flaws either. It basically makes a giant jump from explaining BJT working principle to (half/full) adders, without mentioning not even one example of how logic gates are formed using transistors...)Both LE's as the video i linked share a common flaw: both seem to imply BJTs are used in modern CPU's etc... (or at least are ambiguous about it).

The circuits I glossed over in the tablet looked super interesting though, and I'd especially like to go into detail about the coil layout. It looks much denser than the huion tablet from earlier, but I think it's actually not very many coils but many turns per coil.Thanks for watching!

content: I have to admit I clicked just to hear on which side you'd stand on the walk 'em / whack 'em pronunciation divide. :-)Nice job reverse engineering! Makes me think what else one could do, using just coils and simple logic for NFC communications.There's a tradition in a part of my town of having an "advent calendar" of sorts that is made up of windows in people's houses. People have various kinds of displays, and every day until Christmas another one is revealed.One of the participating houses had some sort of capacitive touch sensor made from aluminium foil on the inside of the glass last year, and you could use that to turn lighting on, and trigger some event in their display IIRC. Now I'm thinking a coil and a few simple logic ICs is something you could give away to let people interact with art, or whatever weird project one might have.Watching the (previous) USB and tablet video now, great stuff. At the risk of seeming like a weirdo, I found the low-level legacy and dirty protocol hacks part really interesting.
