Fixing a ferrite antenna control knob (BD563A)

ferrite antenna control knob
Bakelite can be pretty fragile

The control knob of this Philips BD563A broke because the previous owner didn’t notice or care that the knob was turning heavily and so after a while it broke out.

Since it is basically impossible to get the right colour AND type of knob, one has to come up with something. Printing a new button is not an option, since I do not own a printer and part of the knob is in plain view.

So I fabricated a sliding axle and have affixed part one of the control mechanism onto it. No glue, just a precise cut and some thinking it over many times.


How to reset Joomla (admin) passwords in MySQL

Oh joy, you lost the admin password. Now what?

If the admin user is still defined, the simplest option is to change the password in the database to a known value. This requires that you have access to the MySQL database using phpMyAdmin.

“what, no hacking?”, I hear you say. No. Again, you need access to the MySQL database by using phpMyAdmin.

  1. Navigate to phpMyAdmin and select the database for the Joomla site in the left-hand drop-down list box. This will show the database tables on the left side of the screen.
  2. Click on the table “jos_users” in the list of tables.
  3. Click on the “Browse” button in the top toolbar.
  4. Find the user whose password you want to change and press the Edit icon for this row. A form will display that allows you to edit the password field.
  5. Copy the following value into the password field and press the Go button.
  6. At this point, the password should be changed to “secret”.
  7. Log in with this user and password and change the password of this user to a secure value.

Should I use VestaCP?


Only recently it got patched because it apparently puked out the root password. Secondly, Roundcube is horribly outdated and not easily to upgrade. It also still has the white-space bug, preventing you from logging in.

If you finally fixed the bug and managed to log in, you can’t send any email. It’s supposed to run out of the box and it only does it partially. The interface is easy and once it works, it does the thing. But generally, it’s poorly maintained.
