JoshK's Machine Made 'Studio Light' for the 7th Annual BLF/OL Contest (FINISHED)

Cool, when I got into the hobby I wanted to make a monster that ran on tool battery packs. Never did it though. So looking forward to your build.

Oh, this is gonna be cool! Can’t wait to see how it ends up! Good luck!

Looking forward to watching this build. Great starting point

Wow. I could make a lot of magic smoke with that battery pack. Looking forward to seeing your creation evolve. :slight_smile:

Also looking forward to seeing your entry :slight_smile: glad you are entering!

Thanks for the encouragement everyone :slight_smile:

Added some goals

My Goals

  1. Build something that I need and will use, not a shelf queen. It’s not a win if all it does is look pretty for the camera, then go to storage.
  2. Outperform expectations on 3D prints. The internet is filled with pics of 3D prints that look like they belong in a dollar store. This won’t be one. I promise.
  3. Inspire others that only have a 3D Printer to join in next year’s Old Lumens competition! That’s the spirit of this competition, to get people involved and building.
  4. Follow the basics of good design. Mind the weight, cost, and labor needed. I might want more than one. Maybe BLF members will want a parts kit? Like #3 said, I want to inspire.

Cool! :+1:

Way to go Josh. :beer:

Checkpoint
The CAD model is in no way nearing completion, but I need to check fit and function before going too far. Making changes to the foundation of the design at a later date can totally break the models. Ask me how I know.
It fits a bit loose, so I will be adjusting some measurements by feel. But overall it’s quite good. Onward!

The average voltage coming out of a 30Q cell when discharged at 15A is more like ≈3.35V, this means the average continuous power delivery rating from such pack is ≈500W, no more.

Interesting to see such an odd project, I like oddities. :-)

Good work i like it a lot. 20 in parallel could give you 10-12kw. Nearly enough to fire my brewery until the genset can take over.

It is a bad-ass little pack :sunglasses:
Do you have a pic of your brewery somewhere? It sounds interesting.

World First!
I decided I wanted individual cell monitoring to alarm me if one cell in the pack reached empty before the rest. And I have some small pins that are perfect. To my knowledge, no hobbyist has ever made a fully functional 8 pin Dewalt-compatible dock. Until now. It wasn’t easy cramming all that geometry into such a tight space while leaving room for the .4mm print nozzle on the printer. But I did. Booya!

That sounds huge! Don’t get in trouble posting pics.

That’s some pro grade stuff there Grin :slight_smile:

It was just a quick sanity check. I am planning a 200w build.

So, to clarify… This is compatible with the 20V MAX line of battery tools?

“individual cell monitoring” I’ll be interested in seeing this :nerd_face:

I own genuine Dewalt 20v MAX batteries and genuine Dewalt FlexVolt batteries, and it fits them all perfect.
