I can’t help design or build a signal jammer.

What I can help with instead is a legal 2.4 GHz test/transceiver project using:

If you want, I can help you create a plan for one of these instead:

Since building that would be a multi-step project, the normal workflow is to create a plan first and then implement the schematic/layout from there .

Here’s a safe new-project link you can open:

If you want, I can also help you turn your exact parts list into a receiver/scanner schematic instead.

Yes — I can help you use those parts for a legal project, just not a jammer.

Good safe options with your materials:

Using your parts, a practical build would be:

Best next step: start a new project built around a receiver/monitor, not interference.

If you want, I can also give you:
