Video Tutorial: Writing code onto Micropython Wemos D1 using Ampy

Last week we covered how to flash Micropython onto an ESP8266 (Wemos D1 Mini) but we had to type our code into the REPL by hand. That’s not terribly useful for a real world project, so this week we learn how to upload code and make it run on boot. We’ll be using a tool called Ampy, by Adafruit, since the Micropython world is a little immature.

3D Printing: Knurled brass inserts using a heat gun

In my current quest of building the Hypercube Evolution, one of the early and critical steps is putting in the knurled brass inserts into the 3D printed parts. These inserts are the receptacle for screws/bolts that would otherwise chew up the plastic you’ve printed. The standard instructions are to use a soldering iron but I wanted something with a little more accuracy so I used a heat gun. It works...

SocketIO IRC-style Tutorial – Part 2 – Getting started

This is the 2nd post in a multi-part tutorial series on Socket.io. See Part 1 here. As with all things in life, code is in a constant state of change. Eventually, this tutorial series will be improved, but so that we can all stay on the same page, let’s start with the same version of code. You can go to ShakataGaNai/socketio-sample/d9b7bcc132 to browse the exact working copy this tutorial is...

SocketIO IRC-style Tutorial – Part 1 – Intro

One of the technology things that excites me the most is the use of Websockets to help power the “Real Time Web“. When you use a modern browser and use a web based chat system (like IRCCloud), it very likely uses websockets. Twitter feed constantly updating? Websockets. Facebook feed growing as you waste the day? Websockets. “Real Time” Google Analytics? Websockets. You get the idea, lots of cool things we...
