  1. Diode Bridge Rectifier Verification Hello I am trying to verify the diode circuit labelled "Diode Bridge Rectifier" above. Diagrammatically, it can also be represented as: On placing the positive terminal of my voltmeter (switched to diode mode) on one of the AC terminals and the negative on the other I get a reading of 0.130 V. When I swap the terminal positions, the same reading repeats. Is it safe to conclude the bridge is broken? My google search say the reading should be OL. But verification from this forum would be helpful.

  3. I am interested in DIYing a 3d Printer at home. This is my first to start a project. Firstly, I need to calculate what materials, components and supplies are needed? This is the Electrical Components Required.datsheet Ramps 1.4 controller board x 01 Nos. Optical endstop switch x 03 Nos. NEMA 17 stepper motor x 05 Nos. PCB heatbed x 04 Nos. E3D v6 hotend x 01 Nos. A4988 stepper motor driver x 04 Nos. Power supply 12V/20A x 01 Nos. ATMEGA16U2 Microcontrollerdatasheet Is that all? I am not sure.Thanks for you sharing your advice
