Earth Day Cynicism (Not mine)

Earth Day bugs me.

Okay, not Earth Day itself. The idea of respecting and preserving the world is difficult to argue with. No, what annoys me is all the big corporates jumping on the bandwagon just to be seen to be there.

These companies do, effectively, nothing, or at least nothing actually useful, just to say that they’re supporting Earth Day. It’s worth talking about a couple of examples.

My employer had committed to turn off the lights that illuminate the logos on all its buildings for our lunch hour. They also suggest that we turn off unnecessary computers and other equipment for the same time. They generously suggest that home workers to do the same.

Otto: Assembly

With all the pieces printed or purchased, it was time to assemble Otto.

Since I’d already tested the Arduino and enlarged the holes for the eyes and stepper motors, the process of putting it together was actually fairly uneventful.

Putting Otto together

Because of the small size, some parts were very fiddly but it wasn’t hard per se. Kudos to the people who put the instructions together!

I came across three minor problems.

Otto: Electronics

The first stage of building a dancing, obstacle avoiding robot was to build the body and legs using my 3D printer. The second was to test the electronics before assembly. This would prove to be more eventful than the printing.

I was least sure about all the electronics. They components arrived and… they sure looked okay. I didn’t think the buzzer looked quite right — it looked too big, but I figured that it even if a little lose it should make something approaching a buzzing noise.

New project: Otto

My wife got me a 3D printer for my birthday/Christmas. I’ve printed a few little things since then, but I’ve been itching for a bit of a project. I didn’t want anything too ambitious but, clearly, there’s no point in doing something that can’t fail.

After much searching, I decided upon Otto, a walking, dancing, obstacle avoiding robot.

In this post I’ll talk about how I prepared for the project and my thoughts on its likely success (or otherwise).

Reading 2016

Coming into the beginning of last year I decided I would try to read more books. I do most of my reading on my commute and the previous couple of years I had not had to regularly go to an office, so I managed few books and no novels at all.

While my total of twelve books may not set the world on fire, I managed to read some interesting ones so I thought it might be worth writing a few words on each one.

Write to your MP about Brexit!

I’m sick of last years referendum on our membership of the EU being used to justify… pretty much anything. And any criticism is met with “you have to respect the will of the people.”

Well, I’m a person and I don’t think my will is being respected by many politicians and much of the media. The result of the referendum doesn’t say that people are happy with a so-called Hard Brexit, dismantling the NHS or using EU citizens as negotiation pawns.

Apple AirPods first thoughts

I got some Bluetooth headphones about a year ago as an experiment. They were cheap but more than lived up to expectations. The lack of wires really is a game changer, albeit a totally #firstworldproblems one.

But they had flaws. When Apple announced their AirPods I was intrigued. Would they fix the problems while keeping the benefits? At ten times more than my old headphones I hoped so.

They arrived only a few hours ago so this isn’t a thorough review but here are my initial thoughts.

Virtual Assistants

Virtual assistants are all the rage now, in the press if not in not people’s lives.

I am not claiming to do a thorough, like for like comparison. What follows is my subjective, personal experience. Your usage patterns, successes and failures may be different to mine, but I think my conclusions should broadly hold. We’ll see.

I’m comparing an Amazon Echo, an iPhone 6S and the Google app on that same iPhone. I know I’m not using Google Now in its native environment. That was unavoidable and may hobble it. You should bare that in mind if you use Android.

Dongles

When I got my new MacBook it wasn’t complete. I sat it down on my desk and nothing would connect.

I tried to plug in my monitor, but I needed a dongle to connect to my DVI monitor. My FireWire external hard-drive needed an adapter. I had to get a card reader as my camera takes CompactFlash cards. Even my USB hub needed replacing because my new computer came with a newer, faster USB standard.
