Simple Home Security with Raspberry Pi and DropBox

Built using a Raspberry Pi and a Playstation Eye camera, this budget security camera system is a great way to protect your house and spy on your pets whenever you are out and about. It takes shots every 5 mins, then records continuously if any movement is detected. A cron job that runs every minute triggers a python script that synchronises the folder of pics with your folder at Dropbox, which gives you global access.

Ten 3D printers for 2013

From The Register:

You may not know why but you probably want a 3D printer. These are intrinsically cool devices: A mix of engineering, electrical engineering, material science, chemistry, electronics and software.

As an emerging technology you need to understand a bit of all of these to get the most from a hobbyist device, just as early computer users needed to be competent with a soldering iron and writing assembly code. Here we look at ten of the most interesting 3D printers around. There is a mix of technologies, and some are not yet shipping, but it goes to show just how diverse this nascent industry is.

Raspberry Pi + Wii

I recently came across this post showing the capabilities of the Gertboard. What I didn’t realise up to this point was how straight forward it was to connect up Nintendo Wii remote controls to the Raspberry Pi and use it to control programs (and activate the GPIO).

The Wii remote despite its infrared sender is actually a Bluetooth device and can be connected to the Pi via any generic (cheap) USB Bluetooth dongle and a library that turns the signals into something Python can get involved with.

Here’s a Brian Hensleys blog which explains the process of how he did it.

Human ear moulded using 3d printer

Print-out ears may be one step closer to reality, now that scientists are figuring out how to tweak 3-D printers to craft customized ear cartilage out of living cells. Though the printable ear hasn’t been used in humans, the goal is to make these ears reliable enough to be used for children born with deformed ears, and adults who lose them from injuries.

3Doodler 3d doodler goes nuts on Kickstarter

The inventors of the 3Doodler at Wobble Works mustn’t have know what had hit them today.
Their ingenious handheld 3d printer pen was the talk of the Internet today.
The original goal of $30,000 has been smashed with over 30 days to go on kickstarter. The pledge target jumped by $500,000 over the course of the day, approaching $900,000 and 10,000 supporters.
Backers were treated to updates from kickstarter throughout the day.
Here’s a little word from Wobble Works

and here’s a little something our web designer 3Doodled for you while we were frenetically typing away (tweet @its4raz to say thank you!). The reference to “People who make cool things”, yeah, that’s you not us

Wobble Works – 3D doodler on kickstarter

This looks fun if you can wait till October to get your hand on it:

3Doodler is the world’s first and only 3D Printing Pen. Using ABS plastic (the material used by many 3D printers), 3Doodler draws in the air or on surfaces. It’s compact and easy to use, and requires no software or computers. You just plug it into a power socket and can start drawing anything within minutes.

Now with only 32 days to go the 3Doodler has hit over $400,000 in pledges which is fantastic news. We’ve managed to secure a $75 pledge which will get us a 3Doodler pen when they ship in the autumn. Will start crossing off the days 🙂

Raspberry Leaf

A really useful idea – a template for Raspberry Pi GPIO so you can see the PIN numbers when attaching your wires.

Visit Dr Monks site for the print out.

Thanks to Liz from Raspberry Pi blog for the link.

Minecraft Pi API

This wiki documents the Minecraft Pi API Protocol. Handy.

Looks like our Minecrafting is going to be put on hold for the next few days whilst I sort out what’s up with my filesystem.


Stuck at shell..

Any tips on what to do next would be appreciated.

Python and Minecraft Pi edition

A blog dedicated to Minecraft on the Raspberry Pi.


Along with the blog, the nice guys at MCPIPY have provided all their code in a git repo which makes it massively easy to get the scripts onto the Pi.

You can access the git repo here
