Stick 'em up

2008-04-07: Little Drum Machine

Which means I don't need that motor driver PCB I spent so much thought and effort soldering up. Ah well	I put his head on a servo because that zippy little pager motor just wasn't precise enough	Underside. I moved the microphone away from the "bass drum" motor because it was picking up the whining of the motor louder than the drumming itself	Rear view. Ahh, isn't that so much cleaner?
Sampling board on the left (hot glue makes it so easy to mount things)	The final robot. Motor driver on the right side	This helped a lot -- glued small plastic tabs to limit the rotation of the head	My sketched-out plan for the circuitry. Just like the motor driver PCB, it took some clever arrangement to lay everything out efficiently
Fits right onto the microcontroller board	Six hours of soldering, phew	The completed PCB. So much neater	That's a mess
Here's the final messy circuit, just before I recreate it on a PCB using a hard disk ribbon cable to keep things neater	Underside	Once the circuit is finalized, I'll probably solder it up on a PCB to eliminate that rat's nest	He's now almost completed, construction-wise
Reverse view	Bracket fabricated to mount the sonar "eyes" onto the motor	The solder side of the board (I need a finer tip for my soldering iron)	My first PCB -- a motor driver to turn the "head" back and forth
Now he can record his beats, play them back in a loop, and jam out along with them	I hacked a little sampling circuit board, removing the pushbuttons and soldering up wires so the robot can trigger the record and playback functions	Bass drum motor detail	"Bass drum" mounted
Rear view. All those long cables will be trimmed down once I know exactly where I'm actually mounting everything	Some revision of the circuitry mounting, and he's got a little drumstick to bash on things now	Rear view	Main body glued together
Clear as day, eh?	One of the tiny pager motors, geared down and hot-glued to a "drumstick"	The breadboarded circuit. The small blue board is a motor controller for the two tank tread motors, the three transistors to the right of it will each control one of the three "drumsticks", and the green wire towards the top is for the LCD	The underside
The base of the robot	Gluing it up	LDM's 'superstructure'
