New X-Axis Gantry

Here are some renders of the new X-Axis Gantry design that I’ve been working on with Scott!

Update- Because a concern friend had asked me how the new gantry design handles the movement of the Goostruder I’ve added this extra render!

Modified X-Carve and Custom 4-Axis CNC Controller

Here is my fully customized X-Carve!
I originally bought it in 2015 but I didn’t do much with it during College. Fast-forward to 2017, I found myself wanting a machine capable of handling demanding production run, better 3D carving, and to do it all on an Open Source platform as to make future expansions possible.

I quickly ditched the TinyG GRBL shield w/Arduino Uno and pick up some control cards from Mesa, specifically the 7i76/5i25 card combo.

With Mesa cards, you need to run LinuxCNC or MachineKit to talk to the FPGA controlling the CNC. so I download a 32-bit kernel of Linux (Wheezy 2.7.14) to an older dual core Pentium II PC with a trivial amount of RAM.

The design files can be found by going to my GrabCad and Thingiverse pages –

If you’re considering this upgrade, you should know that LinuxCNC is VERY picky about the computer hardware you run it on.

My advice advice to you would be to go read through all the forum posts on linuxcnc.org.

Pay special attention to all the information about GPU compatibility. Also, disable your computer’s power saving features and start with a computer that has only the bare essentials in it.

Getting stuck for three weeks because you didn’t notice how the after-market sound card was trashing your latency numbers isn’t a good time.

I hope you enjoyed this article. If you have any questions about my X-Carve or LinuxCNC, you can comment here or email me, and I’ll do my best to help!

Motorcycle Front End Assembly

Made in SolidWorks 2016 for a Lighting & Rendering Course back in College. I only made this with a few reference images so this isn’t meant for manufacturing – it’s simply a design exercise!

Laser Cutting Progress

Scott Beibin and I stayed up all night designing and building this enclosure for the MandelBot. It’s designed to use a minimal amount of mechanical fasteners, in a style inspired by the Architect Gregg Fleishman.

World MakerFaireNY 2016

On October 1st and 2nd 2016, Brandeis MakerLab and UConn 3D Printing Club, alongside Colgate University and Wellesley College attended the World MakerFaire in New York. We set up a pavilion to showcase community projects, led a panel presentation about maker technologies on campus, and won an Editors Choice Award!

In just 2 days, more than 100,000 people attended the faire — part science fair and part carnival — which showcases invention, creativity, and resourcefulness.

Interactive Media Wall at Boston’s Children Hospital

During a semester-long internship, I worked alongside a team of fellow 2D & 3D Digital Media students to support the Interactive Media Wall at Boston Children’s Hospital. We were tasked with creating assets for several new scenes before a summer refresh. All new assets were created in Cinema 4D, the scenes were built in Unity 3D. My responsibilities included character modeling for the Monsters scene, as well as object modeling for the Ant scene and Around the World scene.

Disclaimer – Chipmonk was rigged and animated by Robin Simon in the following videos.

Monsters Interactive Scene –
Here are some renders of my finished character + footage of the final project from when delivered it to BCH.
