PCB UV Exposure Unit

thingiverse

A UV Exposure Box is a Must-Have for Making PCBs. I've Been Searching High and Low for One That Meets My Needs, but Most are Too Big and Too Expensive. All of the Devices I Found Require an External Power Source, Which is a Major Drawback. So, I Decided to Take Matters into My Own Hands and Build One from Scratch. My Requirements Were Clear: I Wanted a Box that Could Fit in a Small Space, Charge Via USB, Run for a Long Time on a Single Battery, and Have No Buttons or Knobs to Complicate Things. I Built a Box That Can Handle Up to 184 PCBs on a Single Charge - It's a Game-Changer! To Get Started, You'll Need to Solder Some Parts Together, Drill a PCB, Print Out the Files, Program an Arduino or ATTiny, and Then Screw Everything in Place. Detailed Instructions are Available Online at Instructables: http://www.instructables.com/id/PCB-UV-Exposure-Unit/ How I Designed This Masterpiece I Used Google SketchUp to Design All of the Parts - It Was a Great Guide to Have. Having All of the Components and Especially the Glass Sheet Handy was a Huge Help. The Main Body Part Had to Be Cut in Half Because My Printer Has a Plate with Limited Space (150 x 150mm). Next, I Exported the STL Files, Sliced Them Up, and Printed Them Out Using My Printer. Here's What the Finished Unit Looks Like - With the Cover Closed and Open.
