X-Carve Build

To improve the quality of my circuit boards and the precision of the panel, I knew I’d have to go digital. We determined that a CnC would be the best option for this, and after some research, we decided on Inventable’s X-Carve 750x750.

The parts shipped in multiple boxes. The boxes were labeled with their contents and this helped majorly in organization during assembly. 

KFETS Part 4: Circuit Boards 1


The short lights in my first prototype were connected by a circuit board, as were the meter panels displaying resistance. These circuit boards were the first I’d ever made, evident in the uneven hacksaw cuts on the side :), but were a good foray into the world of circuit board making.


After prototyping, I knew which connections I wanted, I had drawn rough schematics on paper while wiring. …

KFETS Part 3: Prototyping 1

The stages between research and a final product can take a long time, with many iterations and prototypes in between. 

After obtaining all the parts, I connected everything with jumper wires and a breadboard for PCB-mount components.

After I was satisfied with how everything was working, I realized that I needed to make circuit boards to mount buzzers (responsive to shorts) and to mount the parts that run the meters. …

EngX 2018

On February 24, 2018, the USC Viterbi School of Engineering and the Armani Labs are holding their annual EngX event in the Epstein Family Plaza at the university. Presenters include USC students along with JPL and USC’s Insitute for Creative TechnologiesFor more information, visit the EngX website here.

Making Basic Packages in EasyEDA

While making the KFETS, I used the free EDA (Electric Design Automation) software EasyEDA in order to lay out my schematics and circuit boards. Recently, I encountered an issue which I thought could be best resolved by making my own part. It took a little while for me to figure out how to do this, and in the end I figured out that I had to make a basic “package” including a schematic (Schematic Lib) linked to the pad layout for a circuit board (PCB Lib). …

KFETS Part 2: Research

Before starting this project, I researched to check if anyone had made a similar project in case I could use some aspects of their designs. I found similar boxes, but most of them had a 1-meter layout instead of the 3-meter design that my client had emphasized.

The main idea that I gleaned from these designs was the resistance meter being an analog-style ohmmeter based on an ammeter wired in parallel with a 1 ohm resistor and with a 1.5 volt battery, adjustable with 5

DTLA Mini Maker Faire

Had so much fun today presenting along with 45 other makers/groups at the Downtown Los Angeles Mini Maker Faire at the Los Angeles Central Library! With over 1500 in attendance the Faire was a total success. There were so many cool projects and people. I had such an amazing time!

KFETS Part 1: Introduction

For several months, I’ve been working on a system to check the quality of equipment for the sport of fencing. This project was commissioned by H.O.M. Fencing.

Electronics are used for the scoring system in fencing. Each fencer has a sword connected to a body cord, connected to a reel at the end of the strip. This reel connects to a scoring box. Whenever each fencer hits the other, the electrical loop is completed and the scoring box registers this. …

DTLA Makerfaire 2017

Honored to be presenting at the DTLA Mini Makerfaire on December 2. Hope to see you there!
