I recently started experimenting with home made percussion sounds to make practice at home more productive. I live in an apartment building so I have to respect my neighbours which is why I focus mostly on quiet alternatives.
The first thing I did was Jerry-rigging one of my pads so that it now has a kind of pipe band snare drum effect. I did this by placing bb gun bullets in a small metal lid which I attached to the pad by wrapping a thick rubber band around both the pad and the lid.
I also taped an egg shaker to a wrist band which serves as a great alternative for a hi-hat pedal sound when wrapped around the left foot. For bass drum sound I simply tap my right foot on the floor. The key is to record the feet by placing the mic (I use a cheap head-set mic) on the floor close to the feet.
Brushes sound great on any cardboard surface, my favorite being a pizza box. For the sound clip below I used an A4 paper sheet, which is also fine.
Then of course you can use pencils etc to make clave-like sounds.
As for recording, I use a program called Audacity. It is easily available on the internet and free.
I think that I am onto something here. Since starting these experiments I've really enjoyed practicing at home a lot more than before. Until recently I've done a lot of pad work at home, focusing mainly on pipe band snare drum scores, and I've felt a strong need to do something creative and new in order to make home practice more complete. I will definitely be experimenting with more ideas and maybe record some pad battles between my numerous alter egos
Here is a sound sample of my first recorded experiment:
