XT - 30 Motorcycle Phone Charger
Not a huge achivment by any means. But made life better for a client.
A perspective client approached me with an issue. His solution for charging his phone via USB on his bike was taking up too much room under the seat
They had previously wired a car cigarette lighter / 12 volt port and then plugged this in.
What's an XT-30?
It's a non latching /friction held polarized dc connector capable of up to 30 amps. It a very robust connector in a very small form factor.
if I had had a latching connector on hand I would have used it. but the XT-30s fit together extremely snug so I doubt it would ever be an issue.
For strain relief I epoxied the connector to the the pcb.(actually dripped it between the plastic of the connector and the pcb) Which was isn't ideal but was far better than relying on the solder joints the take the brunt of plugging and unplugging
To get the case back on I simply melted out enough of it to get the xt30 to fit in the end where the pin usually went in the 12 volt cigarette lighter configuration.
Do you have a lawn tractor you use to plow snow? Ever wondered if you could make a manual snow plow attachment into a push button? A friend of mine had a riding lawn mower and snow plow blade attachment. Every winter he used the riding lawn mower to plow the driveway. The plow was a kit that bolted on the front of the lawn tractor and it had a mechanicaly actuated adjustable snow plow blade. The issue and this project came about when the arm to adjust the snow plow blade broke. I had just bought a mig welder. I had also watched linear actuators capable of handling 300lbs of force drop to $25 on ebay. Here's what I came up with for converting a riding lawn mower snow plow into an electricity adjusted lawn tractor plow. Repair The lawn tractor snow plow kit had seen better days. The fork that attaches it had bent /deflected and spread. I used a map gas torch and a bench vise to squeeze the tongs back and then welded some L channel angle iron on the sides.

This post is for anyone interested in owning or building a CD welder. I wanted a reliable Resistive spot welder for lithium ion pack construction and or repair. I didn't want to spend 3k or buy from china. I decided to design and fabricate my own. Bellow is my first crack at a Mosfet Switched capacitive discharge mcu controlled spot welder. This post is a work in progress. If you've stumbled across in hoping to build your own cd welder feel free to ask questions in the comments section. I'll provide any help I can.
