JWoodrell 285 Posted March 30, 2014 Share Posted March 30, 2014 well I needed a full 24v supply to test my project here (only 300 mA) and i thought hey i can snag the 12V and -12V rail from my workhorse ATX supply i have, but then i thought this morning, HEY i got that Dangerous prototypes ATX breakout board as a prize on the forum here a while back although at this point i don't remember for what. so i was off to the races, resoldering and reworking the dc half of the ATX supply board to clean up the wan-hung lo construction and massive blobs of solder all over everything... anyway it now only has a single line from each rail to the pin on the breakout board rather than the 6 to 8 wires per rail for the computer like it used to have, much cleaner and better airflow. anyway stuffed it in a spare 4"x6"x2" project box i had left over, with just alittle encouragement two of the mounting holes for the atx pcb mounted to the mounting bosses in the box, so its actually screwed down nicely. used the stock plastic isolator sheet that used to isolate the pcb from the metal atx frame to isolate the atx breakout from the high voltage stuff, as well as directing air flow around in the case. works pretty well, and not as large as I thought it would end up being when i started. I like how it turned out you can see the LEDs shining through the label for each rail. the guts from my atx, and the breakout board. dubnet, GeekDoc and bluehash 3 Quote Link to post Share on other sites
enl 227 Posted March 30, 2014 Share Posted March 30, 2014 I am guessing that you are using no other line connected supply? Or did you disconnect the output ground from earth ground? Quote Link to post Share on other sites
JWoodrell 285 Posted March 30, 2014 Author Share Posted March 30, 2014 The earth ground is commected to the groundame of the pcb in the same place it was in the metal case (where the pcb mount holes are, i wired those 4 points together and connected the earth wire. That is also the common output line for the dc Sent from my iPhone using Tapatalk Quote Link to post Share on other sites
