  • Scanning for Ideas: Building a Better Rat Trap
    eatsup metal conductors in the controller, killing mechanism) 2- It is hard to get a cell signal from under the manhole, this has been tried and the only solution is to drill the manhole cover and install an antenna on the outside. Keep in
  • On the cutting edge of FEA
    a pickup punch used in progressive dies. The punch cracked at an antirotation feature. Geometry that lowered the strain in the part solved the cracking problem. The underside of a manhole-cover model from LeBaron Foundry shows simulation constraints around the edge. Changing the geometry
