Astrophotography - Building a Wireless Flat Panel for N.I.N.A. Flat Wizard

Good day. Thank you for your project, it was very interesting to assemble it, but I have a small problem. Everything works, the control goes, but the LED lamps, which are very dim at 5 volts, barely glow. What could be the cause of this problem? I used the resistor at its nominal value, that is, the one that controls the field-effect transistor, eh, 330 ohms, and 5 kOhm, but for some reason it barely glows. Perhaps something does not match the transistors. Nor at their nominal value. Please tell me how this could be a problem.

are you using the same LEDs and have you tried reducing the resistance ?

@@craynerd I tried changing the tape. It came to work with two 1.5 V batteries, that is, it glows well, but does not want to go through the circuit. I also changed the resistors. It starts to glow a little better, but I think the field-effect transistor does not open to the full extent, most likely, not that it is faulty, they do not match the parameters. That is, from 2.5 V the gate does not open. I have ordered another transistor now. Eh, I will try. Eh, install it and solve this problem.
