Pedro's demonstrations


Pedro's demonstration table

In the left back corner of the room Pedro showed two items. At the computer monitor Gary Millard's AVI to WAV conversion program is demonstrated. That is why there is a webcam on the table. The recorded files can be shown using Gary's NBTV-viewer program or they can be shown on the disc monitor. Pedro has regular contacts with Gary about these programs.

The spinning disc is a prototype of an easy to build monitor kit. The disc is a 32-line clubshop disc and the circle is a glued on reflective foil. A reflection sensor behind the disc senses the sync holes. In the aluminium box all the electronics is placed. For easy assembly PCB's from the clubshop are used wherever possible.
