[*] not yet asked questions

What will be done?

You can choose to do the voice changer, the fm transmitter (for doing some radio) or just do both. They fit together. Imagine how radio listeners react if there's suddenly a robot voice on their radio :-)

Who can attend?

Everyone. And I mean everyone, even non-members are welcome. But there's a limit on voice changer chips so please send a message here: [1]. Members click on "Edit with form" and add themselves to the attendees list instead.

What does it cost

  • Voice changer: 15€ (1.)
  • FM transmitter: 7€ (2.)
  • Both: 20€ (3.)

  1. There's a small donation included.
  2. See 1.
  3. See 2.

How many can attend?

1001 (nine). The workshop will be repeated on a monthly (or on every second month) basis.


In the workshop only the FM transmitter will be designed because the voice changer takes too much time for that. If you want to etch and solder the voice changer you get a preprinted layout which is proved to work.

  • 13:00 Presentation about Eagle (the CAD software) and PCBs
  • 13:45 Designing PCB: Schematic (from the scratch)
  • 14:30 Designing PCB: Board (from the scratch)
  • 15:15 Exposing
  • 16:15 Etching
  • 17:00 Soldering (FM transmitter takes up to 1h, voice changer takes up to 3h)
  • 20:00 Finally finished. Enjoyig the rest of the evening with some Club Mate and smalltalk.
