Manual and CNC Mill

I had a harbor freight mini mill i used for modifying parts. Its was used to aid in finishing the large laser cutter, specifically modifying the glass CO2 laser tube mounts and the gantry. I also have a Taig CNC mill I've upgraded to and a list of projects to make custom parts for.

Omtech K40+

I have an Omtech K40+ for small projects and sales. Used to make keychains, cutting board engravings, flasks. Also used to make cool light up acrylic signs for my dog Musubi.

Redsail 5070 Clone

This is a fixer upper machine, it functions, but not the best. I used the mini mill to modify the Y axis gantry cross beam, and the mounts for the glass CO2 laser tube. Rewiring this was fun. The lights look awesome!

Laser Cut Signs

Laser cut signs based on images of my dog. Used image manipulation tools to get a black and white photo and then used Lightburn to engrave and then cut out the image on a sheet of acrylic. Light up bases were purchased from amazon to get a glowing sign effect.

CNC Router

Bought this with the intention of rapid prototyping printed circuit boards for projects like my custom keyboard. Still in development, working on the manufacturing process.

PCB Creation

I’ve been learning PCB design through custom keyboard projects and small support circuits. I used Ergogen and KiCad to prepare a keyboard PCB for fabrication through JLCPCB, and I’m now building smaller PCB designs directly in KiCad.

Staggered Ortholinear Split Keyboard

Taking inspiration from keyboards I've seen online, I came up with this! its a staggered ortholinear split keyboard. More ergonomic, but I have to relearn how to type.

P1S 3D Printer

My Bambu Labs P1S printer used for many things.

MSLA Resin 3D Printer

This is a cool printer. Used it for minis mostly. Doesnt get much use but I've had similar experiences with Formlabs SLA and SLS printers.

Water Pressure Boosting Pump

This is the booster pump mentioned in my resume. I prototyped, tested, refined, and redesigned for manufacturing. Built from the ground up by me. Worked with other teams such as marketing, purchasing, operations to finish job.

Wash Tank

A wash tank for the tube bending operation at my current employer. Designed based on specifications given to me. Holds 500 gallons of water and detergent to remove grease and chips from bent tubes. Sheet metal parts designed in Solidworks.

Vacuum System Inlet Valve

Wall-mounted valve used in vacuum systems. The user opens the lid and inserts a hose adapter to vacuum materials. The design went through several iterations, from 3D-printed prototypes to a final SolidWorks design fabricated from sheet metal with off-the-shelf components such as cotter pins and springs.
