Initial Planning As with any good project, I started by doing some boring planning and requirements making to get started in the right direction. As an initial target, I defined the below basic requirements: Must be handheld and cordless (battery power...
Download and unzip the the Sipper code (also in the files area) to where ever you like to keep Arduino sketches (for me it's: /Documents/Arduino). Open the code in the Arduino IDE, you should see several tabs across the top. ...
Design As mentioned in the introduction, the UWB Feather consists of an ATSAMD21 ARM Cortext M0+ for the brains and a Decawave DWM1000 module for the ultra-wide band wireless, in the feather form-factor. The design is relatively simple consisting of...
In the previous post I shared some of my thoughts about this project, and decided to pick a different development board than the Pro Mini that I have been using so far. Don't get me wrong, Pro Mini is great for all kinds of small and cheap projects,...
Tardygrade is my attempt to leverage some tried and true mechanical linkages into a simple yet capable robot walker. Rather than trying to emulate gait and leg articulation from biology, I started out with a mostly clean slate. My only two guidelines...
Attempting to make the whole package thinner, I went looking for shorter female pin headers than the 8 mm ones I had used. At western distributors, I found four manufacturers with suitable products: Samtec, 3M, PRECI-DIP, and Mill-Max. Three of them...
Why build my own? Sure, there are dozens of existing robots. However, when I started choosing a robot for my summer camp, none of them seemed to be quite what I wanted. I wanted something: compact (and not too tall)programmable in Python, preferably...
For the sensor pod introduced in Log 1: First obtain the battery and Adafruit Circuit Playground boards (as noted in the Components section.) Next, if you have never programmed an Arduino before, you will need to download the Arduino IDE (Integrated...
I received the shipment of revised PCBs from PCBWay a few days ago. I immediately populated one completely and tested it. I wanted to have one copy of the board that populated everything, including things that I don't plan to actually use myself. I'm...
A few of you may have seen me walking around the after party with a blindingly bright flashy demo running on my badge. More than a few people stopped me to ask me how I managed to do that. Here is a very brief tutorial on how to get the Adafruit NeoPixel...
Wiring the Joystick and Buttons (Optional Soft Mount)This will be the start of your amazing Raspberry Pi Arcade System!First, you must become familiar with the Raspberry Pi GPIO.This will be where you plug in all the buttons and joysticks.The awesome...
Currently I'm using the GY-906 (off eBay) MLX90614 - non-contact IR temperature sensor breakout board. I chose this sensor mainly because it had a smaller field of view than Texas Instruments TMP006 sensor. Adafruit has tutorial's and libraries for both...
As I'm writing this, my 2-days-old Ender 3 v2 is printing the second version of an enclosure for the project. A very bulky enclosure for the first prototype. The first enclosure, or frame really, had a few issues so some very ungraceful adjustments...
