[FIXED!!!] Turn on a lamp with a gesture – Image Processing! Machine learning!

Source: http://makezine.com/projects/raspberry-pi-potter-wand/ Make has a write-up on wand-control with a simple reflective wand… …it *was* broken.  Fixed it. Back in January 2017 when I first read the article I was so excited to try it, I ordered a bunch of parts, downloaded the Git, and then figured out it didn’t work. Not to worry though.  A fellow… Continue reading [FIXED!!!] Turn on a lamp with a gesture – Image Processing! Machine learning!

Lessons on PI – Lesson 4: The Sense Hat (and a little VIM)

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)

Kid-Friendly Electronics Teaching Supplies

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
