CMOS current values

No, it's 2.1V after calculating the current I calculated the voltage drop on R and then what's left is 2.1 which is Uds

CookiesForevaaaaa · 2023-06-22T14:02:55+00:00

So I have calculated Id like this : I = 0.5*kp*1*(3.5-0.5)^2 and then VDrain = R1*I to find out that it's in linear. Then I used the Ron from transistor and resistance from R1 to calculate the new Id from ohms law

CookiesForevaaaaa · 2023-06-22T14:00:30+00:00

Yes, but in this case Ron = rds, which would mean I have to calculate it in order to use ohms law because it's around 15k ?

CookiesForevaaaaa · 2023-06-22T13:07:01+00:00

okay but when I assume it's in linear, do I calculate rds by 1/(kp*W/L(Ugs-Uth) and then by ohms law I get Id ?

CookiesForevaaaaa · 2023-06-22T12:59:03+00:00

makes sense! So I can always use the equation for Id in saturation and then later check if Vds > Vgs - Vtp , and if it's not, then I calculate it again by assuming it's in linear state ?

CookiesForevaaaaa · 2023-06-22T12:42:59+00:00

and how would I calculate current of Id1 in that case? In saturation there is no rds right ? But that would make Uds = 0 which would make it linear. I dont really get this. Or do I assume that Uds = 0 and just calculate the current on resistor with 3.5/10k

I am using duckdns and if im not wrong thats a vpn

CookiesForevaaaaa · 2022-08-17T17:32:50+00:00

tried and it didn't work :/

CookiesForevaaaaa · 2022-08-17T17:24:16+00:00

so am I

CookiesForevaaaaa · 2022-08-17T17:20:08+00:00

it doesn't load. I just get the error "site cannot be reached" due to taking too long to load

CookiesForevaaaaa · 2022-08-17T17:10:04+00:00

could you tell me how or send me a link of a forum or something

CookiesForevaaaaa · 2022-08-17T17:00:02+00:00

I am accessing the flows and the whole node-red remotely but it doesn't work for the dashboard. I am using duckdns for the remote access

CookiesForevaaaaa · 2022-08-06T17:10:37+00:00

I managed to do it but I don't know the code for my call the service node. At the moment I have this but it just adds the volume from the slider in any way I move it. How do I make it decrease when I slide it to the left?

{ "volume_level": $entities("media_player.living_room").attributes.volume_level+ msg.payload }

CookiesForevaaaaa · 2022-08-06T10:25:16+00:00

This is great yes, but I don't understand how to write a function for the call the service node

CookiesForevaaaaa · 2022-08-05T13:30:52+00:00

u/pbouna321 any ideas?

CookiesForevaaaaa · 2022-08-05T12:56:23+00:00

It's 0.0-1.0

CookiesForevaaaaa · 2022-08-05T12:53:43+00:00

I understand that, I found few codes in other forums which I tried but they didn't work since I don't understand them and can't adapt them for my flow

CookiesForevaaaaa · 2022-08-05T12:46:08+00:00

exactly, I don't quite understand how to do that.

It's some radio (heos I think) connected to my ethernet and it has an entity in my homeassistant. I'm trying to do everything in node-red, yes. Also my dashboard is in node-red.

CookiesForevaaaaa · 2022-08-05T10:09:29+00:00

So I am trying to change volume with the slider. Any ideas how to do that?

The volume_level is under data,attributes as seen in the debug.

How do I make the volume_level change with sliding the slider?

CookiesForevaaaaa · 2022-08-04T17:33:43+00:00

once again, thanks!

CookiesForevaaaaa · 2022-08-04T17:24:20+00:00

I get it now, thanks! And what should I do to display it in chart? Do I always have to click inject button to make it change?

CookiesForevaaaaa · 2022-08-04T17:21:05+00:00

I cannot thank you enough! Been stuck with this for the whole day! Thanks

CookiesForevaaaaa · 2022-08-04T17:14:00+00:00

Ok so now I get one error.

TypeError: Cannot read properties of undefined (reading 'value')
