At the time of writing, Argos (a high-street retailer here in the UK) has a sale on DS games, including “Learn with Pokemon: typing adventure“. For someone that doesn’t play Pokemon games (and doesn’t need to learn how to type) this wouldn’t usually be of interest. However, the game in question has one very nice incentive to its purchase: a bundled-in Nintendo Bluetooth keyboard. At the sale price of £9 it would almost be crazy not to snap one up. You can easily pay £15-£25 for a no-name Bluetooth keyboard on Amazon, and I won’t even bring up Apple branded nonsense . This post is a quick review of the package and the keyboard. For reviews of the game itself, there are a few around the internet (note: I don’t have any affiliation with those sites, they were just the first results on Google).
I recently obtained an OpenPicus FlyPort module and StarterKit Nest. I have a use in mind for the devices, but for now they are quite fun to play around with.
For information see:
The main attraction with these devices (for me) was that you aren’t buying the individual parts (which, let’s face it, are much cheaper), nor are you even buying them mounted on a fancy PCB. You are buying a complete product. The currently available software includes the full TCP/IP and Wifi stacks and a web server application that allows both displaying of input values and control of output values from a web browser anywhere on your network. Upcoming software includes an IDE targeted at the capabilities of the devices, with a wizard that looks like it will be capable of generating a lot of the code needed for a variety of uses (see this screenshot). A Bluetooth based module is also scheduled for release towards the end of 2010.
I’m always on the lookout for fun new development kits, and this fit the bill quite nicely.
GSS have released a whole load of new technical documents related to using their C20 CO2 sensor. I was a bit worried when I noticed that the original user guide had disappeared a while ago, but now it’s back, it’s revised, and it has some friends. Enjoy.
This post discusses the C20 CO2 sensor from GSS (Gas Sensing Solutions). It appears to be distributed by Air Monitors and Europa Environmental as the “Miniature CO2 sensor”. Specifically, I will discuss the differences between the datasheet and the actual implementation on the device.
The group obtained some B530 CO2 sensors (produced by ELT, Inc.) to interface to some Arch Rock nodes as part of another project. The datasheet is located here. As a first iteration of my own CO2 sensing setup I borrowed one of the devices to connect to a Verdex Gumstix device. This article gives an overview of how I achieved this, along with some hints and gotchas related to using the sensor.
