Education

Found on YouTube: Abom79

I wasn’t sure how to file this article as I wrote it, In the end I went for education because I certainly learnt a lot from it. Normally, my wasting time on the Internet involves looking at cat videos, or stupid people doing stupid things that result in lots of pain (Say the last bit with the Mr. T voice). Then somehow I came across this guy – Abom79, or Adam Booth to give him his real name. Adam is a metal machinist and engineer who uploads a series of excellently produced videos showing him working on projects for his…

Speaker Cable Sizing – By the numbers

During a recent reshuffle of all the rooms of the house, I found myself going through the laborious process of moving my office, and all the equipment therein. Part of this meant rewiring my monitor speakers. While I was doing this, I didn’t have enough speaker cable, it was too late to go out and get some, and I was too impatient to order some on the internet and wait for it to arrive. What to do? I went into my store cupboard and grabbed myself a length of 1.5mm2 flexible cable, and hooked the speaker up using it. Having plugged in…

DIY Electronics and Home Automation – Part 1 – Introduction

Besides computer stuff, one of my hobbies is playing around with electronics. Having not done anything for a couple of years I decided that it’s time to get back into the subject. As I work my way through what I want to do, I am making a video series to share it with everyone. The video below is the introduction to the series. If you wish to view a larger copy of it, you can do so by clicking through to YouTube.

The council and the NeverSeconds blog. Bullet meet Foot!

I remember reading about the NeverSeconds blog, which is a nine year old girl writing about her school lunches and raising money for a charity providing school lunches in African school a few months back, most likely on the BBC and thinking that’s nice, before moving onto more important news. Yesterday however the blog went from being a backwater internet site, sitting alongside the society for the observance of paint-drying’s blog to being on the front page of almost every major news website, both technical and otherwise throughout the world. Why? Her council decided to censor her. Big mistake. Lets…

Back to school: The start of 6.002x

As I mentioned a couple of weeks back, I signed up for a free online self-study course in Circuits and Electronics, run by MIT under the MITx programme. Today the course started and I wish to say one thing should my Electronics teachers ever see this (David Brooker or Paul Abbot) half of what the course covers I have never seen before. When it comes to pure maths, my skills are pretty week, fortunately Google has been able to help me answer some of the questions, which so far concern looking at discrete abstractions based on the V-I relationship. From…

Updated: MIT to launch free online study courses

According to the BBC, next month, MIT (Massachusetts Institute of Technology) will begin offering a free online course in 6.002x: Circuits and Electronics through its fully automated MITx programme. From the looks of it, it’ll be free to join from anywhere in the world, and those that complete it successfully will receive a certificate, while MIT students can complete the course as part of their degree. Apparently there are plans to offer more courses in a wide range of subjects once this initial trial has completed. They say that there are no formal entry requirements for the course other than…
