First, you need to sign up for an API key from TMDB. Visit the TMDB website, create an account, and navigate to the API section to generate an API key. This key will allow you to access TMDB's data programmatically.

Using your TMDB API key, write a script or use command-line tools like `curl` to send HTTP GET requests to TMDB's API endpoints. For example, you can fetch popular movies data with a request like:
```
curl -X GET "https://api.themoviedb.org/3/movie/popular?api_key=YOUR_API_KEY"
```
Store the JSON response in a local file or a variable within your script for further processing.

Download and install Typesense on your server or local machine. Follow the official Typesense documentation for installation instructions suitable for your operating system. Once installed, start the Typesense server to ensure it is running and accessible.

Decide on the data schema for your Typesense collection. Based on the data you fetched from TMDB, define the fields you need. For example, you might create a schema for a "movies" collection with fields like `id`, `title`, `overview`, `release_date`, etc. Use the Typesense dashboard or API to create this schema.

Write a script to transform the JSON data from TMDB to match the schema you defined in Typesense. This involves mapping fields from the TMDB JSON to your Typesense schema and ensuring the data types are compatible. Python scripts or JavaScript can be used for this transformation.

Using the Typesense client library for the programming language of your choice, or using `curl`, push the transformed data into your Typesense instance. For instance, in Python, you might use:
```python
import typesense
client = typesense.Client({
'nodes': [{
'host': 'localhost',
'port': '8108',
'protocol': 'http'
}],
'api_key': 'xyz',
'connection_timeout_seconds': 2
})
client.collections['movies'].documents.import_(transformed_data)
```
Ensure to replace `'xyz'` with your actual API key and provide the correct host details.

Once the data has been imported, verify that the data is intact and the search functionality works as expected. Use the Typesense dashboard or API to perform some sample searches on your new collection to ensure the data is accessible and queries return the expected results.
By following these steps, you can successfully move data from TMDB to Typesense without relying on third-party connectors or integrations.
