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.

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.

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.

The first stage of building a dancing, obstacle avoiding robot was to build the body and legs using my 3D printer.

Surprisingly, for someone who has been playing around with computers since I was eleven but only had a 3D printer for a month, I was much more worried about the electronics than the actual making stuff.

So confident, in fact, that initially I placed all six pieces into one print job.

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).

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.

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.

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 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.

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.

According to WordPress, this is my one thousandth post here. I’m not sure how (or whether) I should celebrate this occasion but thought it was worth noting.

ZX81.org.uk has been around in one form or another since 1999. It’s survived the dot com boom and bust, it made it through the financial crisis and austerity. It’s been my “home” for longer than any physical location. It’s outlasted six employers (excluding myself, when I was self-employed) and I’ve had it longer than I’ve known my wife or had children.
