GoldTronic
- Electronic Air Drums
(electronic toy drum kit unit)
 |
At the back you can see a plastic clip, usable to wear this device
at the trousers belt. |
This device is made in China and has 3x 3.5 mm stereo (walkman headphone
style) input jacks those each trigger 2 percussion sample sounds when shorted
to GND. A long time I was curious what was intended to be plugged into
this electronic toy drum kit unit since I didn't find the missing part.
There could have been ordinary electronic drumpads, but by the name "Air
Drums" I expected that it must have been rather some kind of virtual user
interface - possibly a set of light barrier sensors those reacted on hand
or drumstick motion, or the name could also have been a pun in a way that
the instrument used some kind of air inflatable PVC drumpads (e.g. similarly
constructed like the step mats of dance videogames).
Finally someone e-mail me that a set of 2 cabled plastic drum sticks
was plugged into the unit. These sticks contain in their tip each a leaf
switch with a weight which inertia triggers a sound when the stick is moved
in the air or knocked against any surface. Some buttons (or similar) on
the drum sticks select which sound is triggered by each stick.
main features:
-
3x 3.5 mm stereo jacks those each trigger 2 percussion sounds
-
6 sampled percussion instruments {rim shot, hi tom, cymbal, high hat, bass
drum, snare drum}
-
built-in loudspeaker and headphone jack
-
volume control knob (with integrated power switch)
-
belt clip (?) at the back
notes:
The inputs lines don't seem to be velocity sensitive. (I didn't experiment
much with this device yet.) Besides the CPU (14 pins DIL case) the small
PCB contains many discrete resistors and capacitors (to process the input
signal?). When I bought it on a flea market, the brand label "GoldTronic"
was hidden by a white sticker of the German toy company "Hartung".
