Why did you make Res 3 2Mohms? Is it to limit bias currents?

nice and informative, wished you show how to convert the analog signal to degrees on raspberry pi 4 model b

Hi John, thank you so much for this information, really helped me to understand. Was looking for this exact topic and your video is perfect. 🙂

Leaded solder is the best………lead free just cracks and doesn’t hold. It’s garbage……….pure garbage.

Is there a way to talk with ya ask some questions if I may ??

Thanks for the video. It cleared up a few things for me. I'm just starting to use Kikad and it's hard to find videos that don't leave important info out.

There is no way I could do that I’m heartbroken I need that feedback 💔

300 deg , air flow to half

Can't hear you properly with the goddam mask on.

I did the same thing and I got the clearance problem pad to top layer and region. I prefer not to waive the DRC and solve it fundamentally. I had the same problem in Cadance PCB editor. PAD and top layer copper should not collide. The whole shape should be a pad in Cadence and I think here needs the same treatment.

Nice bro! 😊

Thanks for the explanation. The preheater would perform the same sort of function as a hot plate, correct? What kind of solder paste are you using?

I was worried far too much solder was used. I see you got the visible bridges but what about the possibility that bridging can happen under the IC far enough that its not visible?

There ARE ways around the ergonomic issue

Maybe you could have just the strain-gauge, and a three-conductor slip-ring attached to the shaft?

very cool !

I go the other way when I see those junk female crimped maybe $.00002 jumper ribbon connector huh?

This video is comfy

Can you link to a reference for the hot keys you use for changing settings and modes?

Oh my God I'm going to come back to this one the list of what you did right and said versus the list of what you did wrong and said oh my God Only thing really I can think you said right is that reflow heat gun goes into standby mode when you put it in it stained and that's because it's got a magnetic read switch in the handle and little neodymium magnets in the stand... And watch out the hot air gun can burn you Let's see what else I like that you pre warm you're bored not your pre warmer though I will come back to this in outline lake everything wrong but And I say this with respect but if you ever read a datasheet for any of these components and looked at the reflow slash solder temperature chart for the part or any SMD cuz they're all pretty close but My speech-to-text is my location right now is Cappy location so I'll come back to this but I do hope you take what I say in this and my next reply

Lol finally moved to the dark side. KiCad for life

Mask? Why? It has absolutely no positive effect on your health. You inhale all kinds of fungal spores etc after a while. Not good! And it cannot block transmission of any viruses.

really too much time spent showing how to stuff a 4th wire through the servo case. Not really informative. You seem to struggle with the whole deal, as if it was the first time you have done this. Perhaps if you had spent the time (post fitting the blessed wire!) and shown us the full story, i.e. connect to a scope, measure the value and use it to retro-position the PWM back to the servo again. Really, 16:57 of my life I will never get back again.

You definitely made it look like it isn't hard. do we need lead? we have lots of flux...

Thanks John well explained.

Lead free is just a pain unless it gets banned I'll stick to leaded

Still coming back to this every time I make a PCB 😅

Thank you for this

very helpful

Hi John - Thanks for making and sharing this excellent presentation. I have a couple of questions I’m hoping you can answer. One, is it possible to make a version of this that could operate from a single battery (e.g., 9 volt battery)? Two, I’ve read that piezo devices can build up a high voltage when disconnected and that it may be wise to protect the input op amp using reverse-biased diodes. Do you view this as a concern for your design? - Thanks again - Jim

Thanks for sharing 👍

Nice work, detailed explanations.

If it won't let you go into R: drive, I just remapped and it worked

and....?

nice vid , might want some lorazapam , snipers use benzos to keep steady aim , might help you to stable your hand...

Lead Free Solder = Sadness...

Is the process different in 2021? We truly live in the future

Thank you for the great presentation! Really clear explanation.

10 mV diode drop is still too high! should use an additional opamp as a precision rectifier.

10:06 Keep yer stick on the ice!

Oh boy a two for one special!

Can Alumni get access to the VPN pls?

My Man Strikes Again!

Ok youtube recommended

I wouldn't call ground and positive a signal,it's just applying power. Regards the feedback wire: if the feedback voltage is used to supply a too big load( not necessarily a micro controller), it could probably confuse the feedback to the servo chip. Pls let us know how you use the feedback on the white wire.thx.

Excellent lecture but I am confused about the last part - - the method to measure and calculate common and differential modes (and rejection).

What the hell! I finished all three videos on instrumentation amplifier and I learnt so much about how the heck 'common mode rejection' works, and that 'reference' resistor can be used to adjust offset and/or increase common mode rejection ratio! I think common mode rejection ratio is equivalent to offset. Which means offset causes common mode imbalance, which directly translates to less noise rejection. I wish to learn more about this subject matter as it is intriguing!
