***New Project*** First Portable PCB Saw Table

After some time creating and cutting my PCBs with hand saw I decided to stop practice that and make something more suitable for 21.st century and that is Portable MINI PCB SAW Table. Also, as all my Project are on budget the same is with this one. I made it with minimal costs, Motor was from my old electric driller, table was found in garbage only thing I had to buy and give to processing was bottom aluminum plate, motor holder and saw blade. PWM controller left from another project, case as well. So overall price is <50$


Parts:
  • 1-Electric driller with battery (18V)
  • 1-Old saw table 
  • 1-PWM controller (from ebay)
  • 1-Saw blade
  • 1-Enclosure for controller
  • 1-Green LED
  • 1-1k Resistor
  • 1-Toggle switch 
  • 20 cm of velcro




Battery from hand driller




PWM controller

This is first try with PWM controller. Everything is nice labeled on PCB so there is no problem with it at all.

Added LED, Toggle swithc

Front panel of enclosure

Velcro is applied on the bottom of enclosure to provide easy access to controller. It handles enclosure really good without potential moving while carrying around.
