Sizzler Posted October 24, 2010 Share Posted October 24, 2010 I just got a new power supply, and with out checking it I hooked up to the servodog and ir motion detectors, and after doing a walk test of motion detectors, i smelled burning electronics, I found that i melted the IC5 Mosfet on servodog:(. I just un-soldered it, but can't read it fully. I can make out this much is from ST (stmicroelectronics) e3 in circle then 2n, then 7805 or 2805 This is where the melt is then on bottom i only can get gk. If anyone that has one can you please look at numbers, so that I can order a new one ASAP, I need the inputs for trigging my halloween pneumatic props. I can do without the 3axis talking skull(still working the sequences anyways.LOL. Any help tracking this IC mosfet would be great.

Sizzler Posted October 24, 2010 Author Share Posted October 24, 2010 Forgot to add that power supply had 4 leads coming out of it 2 were red pos, and black neg. other two had red as neg. and black as pos., so i had reverse polarity on servodog and a couple motions, funny the motions worked well reversed. After examining the diagram it states on it that 2 were in reverse. Let that teach me a lesson that things arent always as seems. Link to comment Share on other sites More sharing options...
Sizzler Posted October 26, 2010 Author Share Posted October 26, 2010 Jeff, Thanks for the reply. Mine melted right below the 7805 which i now think the 0 is a D when turned to side a little it turns to D from top looks like a 0. I can't read anything below that where your M911 (looks like a 11?) is. I talked to Dan today on phone and he thinks he might have one around the shop somewhere. When I finally get the chip I'll see if any damage went pass it? Does it look like there is a GK in front of the M9? Buckey looks sad, and dead without brain.Don Attached files Link to comment Share on other sites More sharing options...
