This is my journey through the trials and tribulations of
How to Make (Almost) Anything.

About

Don Mateo Coates

I was born and raised in the Silver Lake neighborhood of Los Angeles. I went to Harvard and graduated in 2007 with a degree in Mechanical Engineering. I am currently pursuing a dual MBA/SM Mechanical Engineering through MIT's Leaders for Global Operations Program. I am interested in the commercial applications of Digital Fabrication and Additive Manufacturing. I one day want to print my own rocket and head to space.

Weekly Timeline

Week 1

Final Project Brainstorming

Just getting my bearings

Brainstorming final project ideas - ballistic rocket, drone that noses up and has controlled crash over destination using just GPS, hearable technologies using advanced ear scanner from Lantos Technologoes? Project progress (or lack thereof) can be found by clicking above.

Week 2

Computer-controlled Cutter

Laser cut Rocket Press-fit Kit

Used the vinyl cutter to make a sticker for my MBA name placard in honor of a great pre-f(x) trip to Mykonos. Crudely protoyped my rocket that will go to space with cardboard.

Week 3

Electronics Production

Milled and soldered a usb stick

Milled a usb stick on a copper plate and then soldered for the first time! Went mostly smoothly, except for the time I vacuumed up the first usb stick I milled.

Week 4

Computer-controlled machining

3D printed a helicopter blade

Used rhino and grasshopper to design a helicopter rotor. Each blade has a different twist and pitch. Parametric design made that easy to manipulate - though high set-up costs. Cavity inside rotor mount could only have been done with additive manufacturing.

Week 5

Electronics Design

Designing a fish circuit board

Documenting Temporary Failure: Used KiCad to recreate the Hello World circuit and add a couple LEDS and a button to open ports. Adding a couple of components turned out to be harder than thought. Exporting a PNG turned to be harder than thought. Milling is impossible with a terrible resolution file. And my soldering skills are still need of a lots of work!

Week 6

Computer-controlled Machining

Make something big

Used the Onsurd to make a temporary table extension for my dining room table. Eating off OSB is probably not wise in the long run. Also OSB was unable to support my snap design. But will use this as a prototype for possibly a follow-up in nice pine.

Week 7

Embedded Programming

Attempt at Morse

Attempted to catch-up from Week 5. But turns out I still need to work on my soldering skills. Also realized that I am a bigger fan of high-level programming. C is still a mystery to me

Week 8

Molding and Casting

Making a model sub

Milling a mold to cast a rubber mold to make a model. Learned Fusion and got more exposure to MasterCam.

Week 9

Input Devices

Designing a distance sensor

Modified the hello sonar distance sensor to work with an ATTiny44 so next week I can attach a DC motor to it.

Week 10

Output Devices

Output: Stepper, Input: light proximity sensor

Making a stepper motor board that a light sensor can be plugged into.

Week 11

Team Machine Design

Working with the whole section to create an Automatic Drink Dispenser and Mixer

Making a stepper motor board that a light sensor can be plugged into.

Week 12

Interface Programming

Reading a proximity sensor

Used python and Kivy to display a proximity wheel for a synchornous light sensor.

Week 13

Networking and Communications

Working towards my Final Project

Networking my proximity sensors together.

Week 14

Wild Card - Pick 'n Place

Went through the Pick 'n Place workflow. Link is to Abdul's documentation of what we went over.

Learning you cannot just press a button and make a circuit appear.

Week 15

Final Project

Bringing it all together...

Sigh of relief.
