Custom Linear Actuator (XY Table)

There was a point in time when I wanted to build an XY table with 3D printed components, wood, and hardware only. I wanted to utilize some cheap steppers found on Amazon. This XY table was going to be used for the ACAPP Project, a machine used for createting simple printed circuit boards. The design has flaws, but some of the parts work very well on their own! With some work, the whole system might work, but that's a project I have to save for the summer.

Custom Built Workbench

One thing I need when working on a project is a lot of desk space. The moment I feel cramped, I start to shut down. Previous to this project I had only been working off of a small hand-me-down desk from Walmart, and once I put an oscilloscope and multimeter on the desk, I barely had room to set a book down. So while I was house-setting for a friend who had a fully-stocked wood shop, I decided I should utilize it to build myself a big desk (as cheaply as possible).

 

Custom Electric Motor

So I decided it would be a fun weekend project to try and make my version of the electric machine! I wanted it to be as simple as possible in terms of construction, and also as cheap as possible. So I decided the frame should be 3D printed (as if I would have chosen any other option), and the cores of the coils would be roofing nails that I had sitting around. The magnets were picked up for $6.00 at a local craft store, they are neodymium and measure 2561 Gauss. Most of these dimensions were arbitrarily designed as this was more of a hobbyist weekend project than a technical engineering project. The motor stator and rotor was designed in SketchUp 2015. I designed for the bearing (a skateboard bearing I keep on stock) to be press fit, knowing that once it was 3D printed, it would fit tight, and could be sanded down.

Automated Copper Applicator for PCB Prototyping (A.C.A.P.P.)

The goal of this project is to create a machine capable of manufacturing printed circuit boards (PCB) in an efficient and ”green” way. There are many methods which could be used, but it was decided that the best method to use would be a unique copper tape applicator. Because of this, the machine is named Automated Copper Applicator for PCB Prototyping (ACAPP). ACAPP is still a work in progress, but all of the methodology is planned and is within the range of execution. In this report I will discuss how processes are selected, as well as the finer details of execution.
