After trying to encaplulate electronics in casting resin and always getting bubbles in the resin, it was time to make my own vacuum chamber. With this chamber you can “degas” the resin, eliminiating the trapped air bubbles.
For this build I used:
Harbor Freight 2.5CFM vacuum pump – $100
Harbor Freight Automotive Vacuum Tester – $15
Stainless Steel thingamig from a restaraunt supply store – $15
1/2″ thick plexiglas – FREE from a friends scrap pile
