How smart is your beer?

Øyvind Nydal Dahl at Øyafestivalen 2010It was a cold December morning.

I could see the frost smoke rising from the ice-cold water of the Berlin canals

…and a man from the US greeted me at the door and welcomed me in. His name was Jackson, and he was one of the founders of a hardware startup in Berlin, called Relayr.

I got a tour of their office, and they showed me their technology.

And it was really interesting to see how their technology enabled people to easily make smart things.

Yesterday I waved to 100 people

Oyvind-OsloMiniMakerFaire-croppedWhich seems like a strange thing to do =)

At least when you don’t have the context.

But the thing is, I was at this event in Berlin. Yesterday was the opening of a new electronics lab, that aims to attract both hobbyists and startup companies within hardware.

I thought it was going to be a small event – but a lot of people are interested in building electronics.

There must have been at least 100 people there.

So why did I wave?

A thing I do, that you should not do

A recruit wearing safety gogglesI was browsing the Internet and found something…

I came across a story about someone who had gotten solder into his eyes. He didn’t wear protective glasses when soldering.

He turned blind on one eye, suffered from so much pain that he was unable to continue his job – and was left in a position where he was unemployed and couldn’t pay his medical bills.

This was back in 2011.

Support our mini-display project

A homemade LCD screenMy friend and I built a mini-display.

We bought a replacement screen for an HTC smart phone, added some electronics and a multi-touch panel, and made it HDMI compatible – so you can easily plug it into your computer, Raspberry Pi, Beaglebone Black and such.

This means you can build gadgets with really nice graphics, like a handheld gaming device, or your very own smart phone!

Can you charge a cell phone in 30 seconds?

polarized-capacitor-2220uFNo way!

That was my first reaction when I started researching this.

The editor of, which is the biggest tech-channel in Norway, asked me if I could write an article where I explained what supercapacitors are and what they can do.

I knew about the concept – supercapacitors are capacitors with a lot of capacitance – but I had never really looked into the current state of the technology.

Until now…

How to add WiFi to your project for $3

Image of Arduino board for What is a Microcontroller?I did some Googling today.

And found that you can add WiFi to your project for only $3.

I’m talking about the ESP8266 module. It’s a WiFi module you can connect to an Arduino – or some other microcontroller.

It’s usually $5 or more.

But today I checked and found someone who sold it for only $3!

You can control it by sending commands over the UART interface. The documentation is in Chinese, which can be a challenge for some of us ;) But there are people experimenting with it and translating into English.

I played around with it in Berlin at a workshop a few months ago. It was really cool.

So this is what I’ve been doing these last days

sales-video-screenshotToday’s email is later than usual.

The reason is that a thing I was gonna do on Saturday – that I thought would take a couple of hours – turned out to take several days.

But now I’ve completed it.

I’m a bit tired now – so I’m gonna keep it short.

I wanted to offer something for those who are hungry for more than just an eBook.

(And my video training is currently not available for purchase. I’m upgrading it. More on that in a later email)

Circuit Board Recycling

Circuit board recycling necessaryCan you get money for your old circuit boards?

Apparently yes…

Anne Staley wrote to me a while back.

She was very enthusiastic about the environment and recycling. And she asked me if she could write an article on my blog about this.

I answered that it probably wasn’t something for my blog.

But she persisted. And she wrote the article and sent me. And as I read through it, I realized that it could be an interesting thing to learn about. Even as a hobbyist.

It turns out that you can actually earn money on your old circuit boards. Circuit board recycling sounds like a good idea =)
