I have been building projects using PIC microcontrollers for years. This is one of my best devices. This is used during a speech in a Toastmasters club to inform the speaker of their time remaining. Green LEDs indicate they have spoken long enough, red means time is up, and yellow is halfway in-between. All of the LEDs are colored, even though some appear clear in the photo. The control panel and LCD display offer great flexibility in how the timer operates.

Fishing line power transmission.
The first time I saw the Timescapes teasers I knew I would have to build a camera slider and explore the timelapse world for myself.
After a lot of research on this forum and a lot of late nights I have finally tested my motorised camera slider.
Lego gearset (don't laugh it works a treat) fishing line power transmission, aluminium door frame extrusion, Arduino micro controller and a 12v stepper motor. Note the termination of the fishing line with stainless steel thimbles and cotton covered hair bands, this takes up any harsh speed changes or direction changes.
All my demo timelapses have worked just fine.
The attached photos might explain the build better.
