PWM Fan Controller used to cool an External Hard Drive
DIY Hacks

6

I made a PWM Fan Controller to cool my external hard drive that got quite warm when it was running for an extended period of time. There are 4 videos documenting the build below. Have a look at the project page for the schematic, code and additional information. The heart of the PWM Fan Controller is a PIC 12F675 microcontroller. This microcontroller is reading the analog output of a LM35

Strobe Array
Complex Hacks

Strobes are an effective way of creating atmosphere. Wizz Engineering designed a huge Strobe Array which used 24 small strobe lights that were controlled using custom DMX stage lighting equipment. “The Strobe Array is a matrix of 8 x 3 small 10W stroboscopes. Each strobe has a relay soldered into it which forces it to flash, and the relays are controlled independently by a MPLI DMX512 interface. Patterns where selected
