I would like to introduce you to the diy pick and place machine which I have been working on with my brother for the past year.
The machine is driven via the Mach 3 API using a custom .Net windows app via a SmoothStepper Ethernet interface for driving the main stepper motors and I also use an Atmel microcontroller to drive a stepper motor for the component picker system.

The machine had to fit into a small space in my loft workshop and contain all the power and drive system within its own footprint.
11411
The chip feeder is a vibration design using a vibration motor from an xbox game controller.
11412
The tape fed components are supplied via modified panasonic feeders (cheap via ebay) and is actuated via an air ram.
11413
The pnp machine has two picker heads driven by NEMA 8 motors.
11414
The first version of the controller system used 7 different control boards and we have just finished an upgrade to make a single USB host control board which uses a Microchip PIC as the USB host and this controls the vacuum valves, led lighting for the camera module and head led, vibration motor control and communicates via I2C to an Atmel processor which drives the picker head system.
11415
The new control board has in circuit programming ports so the code can easily be changed if needed.

Full details with photos and videos are on my project blog at Brian Dorey.com | DIY Pick and Place (http://briandorey.com/category/DIY-Pick-and-Place.aspx) and i have a lot of videos of the project on my YouTube channel Brian Dorey - YouTube (http://www.youtube.com/user/briandorey)
