Note on my advances in the timelapse slider project:

Materials gathered so far:

1m length of IGUS Drylin W aluminium extruded rail. Rail diameter 10mm, width 80 mm
1x 100 mm carriage
2x T5 pulley 30 teeth
2m T5 timing belt
1x continuous motion high torque servo

1x Arduino UNO board
1x Motor Shield (though I probably will make my own servo controller)
1x mini joystick
1x I2C 16x2 LCD display

1x 12v sealed lead battery 3.3 Ah

1/4" aluminum rod
1x 1/4 BSW 20tpi Tap (that's the thread used for tripods)
1x 1/4 BSW 20tpi Die

2x limit switches from microwave oven ;)

I hope to have time this weekend to start the design of the servo mount...
