BirdBox2015: Picaxe controller details

Progress has been slow due to other commitments, and a heavy bout of man-flu.

But I've been testing the Picaxe powered controller with a RaspberryPi and it works just as I had hoped.

This low power controller may even be a useful building block for other battery-powered application.

An armchair review of the Garmin eTrex 10

I think Santa's plan was to make me more enthusiastic about "...going walkies."

The idea was to try and prise me out of my armchair by giving me a bit of tech to play with while exploring this green and pleasant land.

But what does a hand-held satnav have to offer a casual walker like me?

Normally, the first thing I do with a bit of new tech is install myself in a comfy armchair and spend the next day or two exploring all the options. This proved more of a challenge with the eTrex.

BirdBoxPi2015: using a Picaxe controller

Looking back at my last 2 posts, I started thinking about how I might incorporate a Picaxe into the BirdBoxPi2015 controller.

Although the 8 pin Picaxe is a little more expensive than the 555 timer currently used, it does offer more flexibility.

My RaspberryPi bird box system runs from a 12Volt, 12Ahour "mobility" lead-acid battery.
