RIP MetPi #1

We had 2 storms passing over us at the weekend. One casualty: the MetPi.

Raspberry pi + Amazon Dash button

Amazon has launched its Dash button which allows you to order something (e.g. toothpaste) with a single click through Amazon Prime. You can put these buttons anywhere you like (e.g. in the bathroom in case of toothpaste emergency during the upcoming zombie apocalypse). What's great about them is that you can hack them.

Logpi: prototype #2

After having got my hands on a new camera (the new 8MP Raspberry cam v2.1 not IR), I had to start the design of the Logpi from scratch: cables and sizes are different, software is different.

Logpi: prototype #1

I've been wondering about lifeloggers for a while. I'm not convinced they're useful outside specific events, but as my niece is getting baptised next month, I thought I'd create one and wear it.

Metpi #5: outdoor housing

Once the Metpi setup and adjusted, it was time to put it outside. I looked around at how to build a suitable housing and even though the Stevenson box would look nice, it would be too difficult to build to a high standard. So I went low tech and built one with plant pot plates.
