PCB Designs

 Some of the projects I was working on


The above board is the first one "sent out" for.
Sent out as in, I made the design and sent it to a 3rd party for manufacture.
OSH Park in Oregon does nice work. 


Minus the intended programing  connector here's the final product.

Modular electric manufacturing process controller



This was the evolution of my cd welder board. I intend it to be a multi purpose weld and cutting process controller with modular design.

I intend to try laying it out as a 4 layer board as well.

That would give two options. The first would be roughly the same dimensions but much easier to work with component sizes. The second would be a board about a third the size. Some of the routing on this was a gigantic pain in the ass with two layers.

Actually the size to be further reduced on two layers by moving some of the power components to a separate board.

Lawn Tractor Snow Plow Electric Upgrade

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. Less Play I also tack weld

CD Resistance Spot Welder

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.  My CD Spot Welder  Here's pics of the first working version from 2018
