<h1>Another ATX Power supply things.</h1> <h2>Updates:</h2> 02/03/2020: update part list add potentiometer 26/01/2020:Print ready! update facade after test. update stl files. add Step file, update drawings. (V7) 13/01/2020: update stl file, first print seems to be ok, waiting some parts for the wiring, back of the front face migth be change. 11/01/2020: update ATX dimension, remove wrong STL files, printing test ongoing. <h2>Why I do this:</h2> It is usually difficult to know the dimension of things (no 2D drawings with cotation), so I decided to make one with 2D drawings. It is an excellent excercise to learn Onshape. It is fun! <h2>Specification:</h2> Stabilized power supply ouput: - 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 Parts</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 adjustement potentiometer - 2x 10kOhms potentiometer linear (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: done - Add wiring detailled - Add commercial reference for parts - Add option for voltmeter on 3.3V, 5V and 12V - Add fuse for DC converter protection.
