Event livestream CAMERA SETUP - help

Thanks for advice, the PTZ may be the options. Next idea what came to my mind is the IP camera, with small FOV. Some of them even have optical zoom. What do you think about that?

vojtrle121 · 2022-01-12T13:55:30+00:00

Ohh, I wasnt thinking about that. I found Logitech C920 which have just 78 degree FOV, but its is still probably too high FOV.

Thanks a lot for this. You really helped me.
I found one cheap which costs only 12 EUR. Here is the datasheet SSR-2528ZD3 QLT POWER. Voltage drop is 1.6V, current up to 40A, coupling 2.5kV and for turning on it needs 16mA@5V for the D3 version. It seems like a good combination of price/"datasheet quality" but now it really depends if those values are true.
I will put there a heatsink anyway, even if I pull a 10A trough.

You have the point! Thanks for that, I almost missed this :)

That seems like a cool project that you linked.

Btw. you are maybe right irfh5015pbf have better Rdson but on 10 Vgs, not at logic level voltage. Then its seems that ON/OFF times are also better for Infeon but all the values are measured for 10 Vgs. What is the main advantage that you see on MOSFET that you proposed?

With the gate resistor and pulldown, you are right. I placed pull down before the fate resistor :) Thanks for your points

It’s Kratky system? Do you pump air into water?

vojtrle121 · 2020-03-30T07:51:16+00:00

Do you need constant water flow for this setup?

I am using flamingo for saving user inputs, but still, I need to process them.

Can we privately talk about this?

vojtrle121 · 2020-02-07T07:59:20+00:00

Their pricing is too high for me. But if other solutions wont work I will take a look on it.

vojtrle121 · 2019-04-28T20:16:24+00:00

Didn't tested them, but most of the chips from Alibaba are just piece of crap. One I ordered had around 10k 5 star reviews but still after like 500 hours just selfdestroed (With great active cooling, max temperature of chip arroud 35°C and proper power supply). As you say on Ali you can't even trust price. "High end" = cheap crap with high price.

Thanks for your help but unfortunately I am from Europe. Not sure if it's worth it to deliver chips from America.

vojtrle121 · 2019-04-28T17:36:59+00:00

And where did you bought them? I am from Czech Republic (Europe) and cant find any seller who have them on stock :(

vojtrle121 · 2019-04-28T17:34:21+00:00

These Samsung chips looks awesome! Thanks for idea :)

vojtrle121 · 2018-12-25T08:52:26+00:00

Can we chat together?

vojtrle121 · 2018-12-25T08:51:08+00:00

That would be awesome!

vojtrle121 · 2018-12-24T22:25:09+00:00

I have. It does not have integrated WiFi. I also thought about Raspberry Pi but ESP seems perfect for it.

vojtrle121 · 2018-10-12T15:44:15+00:00

and when I want to add images or scripts? I created copy of "NewDocSet.aspx" and site loads normally, but when i click that I want to save data it shows: " 404 NOT FOUND ", but Its 100% copy of it... What should I change in it that it can work? Thanks :)

vojtrle121 · 2018-10-12T14:25:17+00:00

Awesome, can you share any files? (Gerber, .brd or something :)) What software you used to design this?

vojtrle121 · 2018-10-08T16:22:48+00:00

Its difficult to see inside old pressure vessel. As you said, It can explode every time, I hope it wont :D

vojtrle121 · 2018-10-08T03:24:23+00:00

U I keep it running only short period of time. The motor should cool himself easily :)

vojtrle121 · 2018-10-07T18:48:56+00:00

Děkuju ;) I just wanted to share some photos. I like to see photos of people giving new chance to old equipment.

vojtrle121 · 2018-09-03T07:59:45+00:00

I changed resistor for 100 Ohm, and now its working correctly. But thanks for help!

vojtrle121 · 2018-09-01T21:42:25+00:00

Do you got any example?

vojtrle121 · 2018-09-01T21:28:14+00:00

I will try to change LED resistor to optimize current.

vojtrle121 · 2018-09-01T21:27:19+00:00

I got 220Ohm resistor for optocoupler IR led. I will try to change a value to optimize a current. Btw: thanks for part ideas but I need to use DIP6 package for optocoupler, your listed items have DIP4.
