Platform Build Retrospective

On a regular basis, I take a month off of work to focus on projects that are outside of my normal work. In 2018, I decided I needed to build a storage solution for my loft. The project went through a number of stages to arrive at the final design, some of it decided on the fly while working in the shop, so I’ll do my best to recap everything here....

Methane Sensor parts have arrived

A while ago I bought this Methane sensor on a whim because it could be used for something interesting, and now comes the interesting. We have a tiki mask in the bathroom as part of our decorations for that room, so I thought, “wouldn’t it be great if when it got really stinky in the bathroom, the tiki mask eyes glowed red, or flashed or something”. So spawned the Tiki Mask of Fart Detection....

Acrylic In Hand

I stopped by Tap Plastic to get some Acrylic. I bought 4ft x 4ft piece cut in half so that I can fit it into my laser cutter. I have time scheduled on Tuesday to use the cutter, so I’m ready. Since I still had a couple of the test pieces left, I glued one piece together and fit it into the 2” ID tube that I’m using to house the wand....

Drawing Disappearing Images

The idea is simple. A plotter that hangs from a wall and draws on a UV-reactive surface with UV leds as the “paint”. Based on the characteristics of the UV-reactive surface, the picture will slowly fade and disappear over time. Since I want this to hang from the wall, there are two ways I can do it. The way most people do it is with two stepper motors with a spool of rope connecting each to a center puck....

First 3D Printed Object

Today, I printed my first object with the makerbot at Makerhaus. It’s a servo bracket for a Futaba S3004 Servo. The idea is to print two of them, and have a pan-tilt head for a laser or something else that’s relatively light, maybe a nerf gun. It looked like this while it was getting printed: It is quite a fascinating thing to design something in a virtual world and see it slowly materialize in the physical world....

Quadcopter Failio

Delayed update because I’ve been having a bitch of a time getting my quadcopter to work properly. First, the documentation on how things were supposed to be wired up was just plain wrong, but once I get that straightened out, I still couldn’t really get it off the ground. Come to find out, and I hope I didn’t ruin my battery, but the motors are underpowered for the weight. Weighing the quadcopter, it is about 1....

Quadcopter Build Day One

Controller Setup Transmitter Configuration The first order of business is the bind the receiver to the transmitter and configure the transmitter for . This is necessary since you don’t want stray transmitters to be able to control your quadcopter. I found a pretty good guide for the Hobby King transmitter that I have. I ended up using t6config because turborix didn’t work correctly on my computer. The settings that I used are as follows for the different sections:...

Datalogger build day one

I received my Tiny Circuits package on Tuesday, and started playing around with it that night and the next day. They are amazingly easy to work with, except one thing: my big fingers have a hard time screwing the super-tiny nuts onto the bolts to hold them together, but that’s just an annoyance more than anything. Stacking the tinyduino, usb adapter, accelerometer, and sd card shields together, in less than 10 minutes, I had what would eventually be my datalogger....

Trapeze Datalogger Project

Project Abstract An accelerometer equiped datalogger is strapped to a person doing aerial (trapeze, and rope) to measure the force applied to that person through different movements. Parts List A small number of parts are needed, mostly in thanks to tiny circuits and their amazing products. I could have gone with the lilypad version of these, but opted to not make it part of my clothing since aerial is so rough on fabrics....

Change of Flight Controller

My MultiWii board was missing pins and has zero documentation, so I decided to return it and get the KK2.0 because it’s well documented, well supported, and has some good features. It’s lacking the automatic gimbal control for cameras, but whatever. The price was roughly the same....
