How can the PI be a Wifi Access Point??? The Linksys hardware pictured above is synonymous with wifi routers. Under the covers its just a dedicated Linux box and some fancy software. Turns out your PI can be that “dedicated Linux box” piece. In this post, we will cover turning your Raspberry PI into something… Continue reading Easily turn your PI3 into a Wifi Router!!! (Raspberry PI 3 as a Host AP – in code!)
What is programming? Programming is the process of recording knowledge or tasks into code. Code like Python, or Javascript is a bridge “language” that allows humans to write their intent into formulas that a computer can then use like a recipe for action. Computers don’t get bored… In the previous lesson we used git to get some… Continue reading Lessons on PI – Lesson 2(cont.) A little programming…
http://zty.pe/ This game is a lot of fun, and its teaches typing skills quickly. Check it out, its been kid approved. Later, I’ll build a word list you can upload to work on typing specific words.
The Sense Hat What’s a hat? Hats are the term that the Raspberry PI community uses to identify bits of hardware that are made to plug into the Raspberry Pi’s GPIOs (General Purpose IO) – that row of pins along one side of your pi. There are lots of these out there to make interacting with… Continue reading Lessons on PI – Lesson 4: The Sense Hat (and a little VIM)
Digital Currency is inevitable… It’s too perfect (or it will be after a bit more scaling work.) It works everywhere on the globe, the government can’t freeze it or de-value it, credit card agencies don’t have to insure it, and it’s guaranteed to be a limited resource. It’s coming… so you should probably teach your… Continue reading Bitcoin(now Ripple) and the Modern Family
For a little servo background… See my article on the servo-trigger: Servo Triggers – Quickest, Fastest, Easiest way to make your servos dance To install node… See my NodeJS installation article: Installing NodeJS on a Raspberry PI Then… a little something on PWM Ok, a little background: Controlling servos works by using something called PWM or Pulse Width… Continue reading Controlling Servos from your PI (No extra hardware needed) using NodeJS
There are two ways… The easiest is to install using the package manager. Recently though I ran into an issue where the folks providing the package manager version forgot to include the ARMv6 build. If that’s the case while you attempt, move onto the tarball method and you’ll be up and running in no time.… Continue reading Installing NodeJS on a Raspberry PI
The Linux operating system and specifically the terminal, can feel like a maze when trying to find your way around. If you haven’t yet, check out Lesson 1, and Lesson 2. The file and directory File There are a couple of concepts you will have to hold in your head as you get started. The… Continue reading Lessons on PI – Lesson 3: Getting around (ls, cd, rm, mkdir, touch, pwd, less…)
On the Shoulders of Giants That phrase, “On the shoulders of giants”, has come to mean, “discovering truth by building on previous discoveries” which just about sums up all of computer science. That idea, is the reason Computers are moving so fast! When you can reuse the work being done by hundreds of thousands of people… Continue reading Lessons on PI – Lesson 2: On the shoulders of giants (apt-get, and git)
Wago 222-Series Electronics typically means soldering. Soldering means highly stressful training using soldering irons with parental-hands hovering inches from child-hands. Cords everywhere for soldering irons, lead free solder, fume extraction. All of which is mostly impossible with any size group. Turns out we live in a fairly modern time. We can connect wires with tiny… Continue reading Kid-Friendly Electronics Teaching Supplies
