<h1>Another ATX Power Supply Project.</h1> <h2>Updates:</h2> 02/03/2020: Update Part List - Added Potentiometer 26/01/2020: Print Ready! Updated Facade After Test. Updated STL Files. Added Step File, Updated Drawings. (V7) 13/01/2020: Updated STL File. First Print Seemed Okay. Waiting for Remaining Parts to Complete Wiring. 11/01/2020: Updated ATX Dimensions. Removed Incorrect STL Files. Printing Test Ongoing. <h2>Why I'm Doing This:</h2> It's Often Difficult to Determine the Dimensions of Things (No 2D Drawings with Measurements), So I Decided to Create One Using 2D Drawings. This Is an Excellent Exercise to Learn Onshape. It's Fun! <h2>Specification:</h2> Stabilized Power Supply Output: - 1x Fixed 3.3V - 1x Fixed 5V - 2x Fixed 12V - 1 Adjustable Voltage and Current Output (0-12V) <h2>3D Printed Parts:</h2> - 1x Front Face - 1x Front Body - 1x End Body Optional: - 2x Knobs <h2>Other Required Components:</h2> - 1x ATX Power Supply - 1x Power Switch: Type KCD1-11 - 1x Volt/Amp Meter: DC100V 10A Voltmeter/Ammeter - 5x Banana Plug Red - 5x Banana Plug Black - 1x DC/DC Buck Converter: LM2596S DC-DC Buck Converter with 3 Adjustable Potentiometers - 2x 10kOhms Linear Potentiometer (WH148 Type) - 1x Prototype PCB - 10x Dupont Connector PCB (4 Poles): 4 Pin Female Tall Stackable Header Connector Sockets for Arduino Shield - 4x Stud M4x155 - 12x Nut M4 - 4x Socket Head Hex M4x25 - 10x Screw M2x5 - 3 Rilsan Collars <h2>Work in Progress:</h2> - Finalize 3D Part Design: Completed - Add Detailed Wiring - Add Commercial References for Parts - Add Option for Voltmeter on 3.3V, 5V, and 12V - Add Fuse for DC Converter Protection
