Overhead Work Lights

So while I wait for the printer to be repaired and continue down that path, I have a new project.  One that probably should have happened while I was building out the crafting space.

Space.  That is the problem.  Work table in the garage is covered with tools and parts.  Work table upstairs is cluttered with tools and parts.  No good way to clean them up currently as all surface space is used.  Time to go vertical.  I have a shelving kit for the garage Work table that I just need to put together.  The crafting room will require some shelves, but that should be about it.  Doing so may add some shadow to the work surface.

Well, the garage was never lighted all that well to begin with and the upstairs work area

has a nice bright 5 bulb directional octopus lamp, but it sits on one side. I picked up some LED arrays built for cars to put under the shelves to help light up the work space. https://www.amazon.com/gp/product/B00J23EA2U/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I can buy $20 current controller devices … or build our own.  Looking up on solutions, I settled with one by Dan on Instructables:  http://www.instructables.com/id/Power-LED-s—simplest-light-with-constant-current/circuit.jpg

The parts listed were a bit more then I wanted to pay for, so I looked for alternatives.  I often avoided using mosfets if possible as I was unfamiliar with them, but this was a simple enough project and helps me to learn the basics of them… in addition to making the control circuit cheaper than $20.

I modified the above schematic to:

The basics are there, but added a dimmer switch and soft off capacitor as well as a diode… that is probably unnecessary and will be removed. I originally added it to drop the voltage slightly from 12V with the intent of not over-driving the LED array, but I can do that with the resistors and dimmer switch by controlling the current flow.

Waiting on parts at the moment.

 

M3D Pro issues

Problems with the printer seem to be ongoing. Heated bed died within 24 hours. Z belt snapped within a week. Now the extruder gear is somehow destroyed. Unable to return based on the Indigogo method.  Damn shaddy buisness model, but stuck with this machine for now.  They do promise to fix it and it’s been shipped back to M3D to get fixed and updated if newer parts are available. Will see if it comes back in a workable condition.

Thoughts: Should have just got the Prusa Original MK2.
