    Thanks for fixing that drove me a bit nuts until I found the error. BTW I did do a BOM on mouser for this should anyone want it.http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=54cbf7c8a2It might be cheaper to get the mosfets from an overseas seller on a place like eBay. They’re $18+ through mouser for 8 but I picked up 10 on ebay for $7 shipped. I’m currently waiting on those to come in to test themSome of the resistors on the BOM are qty 10 because of the price break for 10+, if you need 3 it’s cheaper to get 10

    Ok I figured out my main issue with V2.2 not pulsing. The BOM has the mosfet driver part number as MCP 14E10-E/P. That's what I had originally purchased which didn't function properly. The name field for this part has MCP1407-E/P. I purchased some MCP1407-E/P drivers and they do function now properly. I do think I killed one or more mosfets even with a the extra protection and one of the 15 ohm resistors nuked itself.

    Still at a loss on this. I do notice I'm getting battery voltage at the welding tips when it's not pulsing (in normal 2.2 programmed mode, not test mode) which the youtube video says should be 0V. I hope the 2.2 pcb file didn't have a problem. I've ordered parts to make a few more of these to test just to see if the first one I assembled was a dud but it's not my first rodeo with SMD soldering. I usually do things smaller than 1206 though :)

    Flashed the nano into test mode. jump the foot switch header with auto pulse off.Power supply in is 12.89V (it's a 12V wall plug). Nano D5 and pin 2 of the mosfet driver is 5V. LED is 2V but on. Mosfet gates on all 8 of them are 4V

    Well I have it all built without R13 populated. The device notices when both probes are placed as the LED flashed but I get no actual welding pulse out of it. Where would you start troubleshooting?

    I have a question! The silkscreen for the 2.2 version has 20k resistors for R1, R13 and R14. The 2.2 version BOM only has 2 resistors of this value needed.Is one going to not be populated, is the silkscreen value off on one, or is the BOM incorrect for v 2.2?

  • How to open and replace the MagSafe cord on an Apple AC adapter

    I'm not the one who did the video, I think I know which specific one you're talking about though.

    1. Yes you can install a magsafe2 cable in a magsafe charger and it works fine. I've done it to several.2. No difference noticed.3. Yes they're the same electrically, just the end is different.
