Futurlec makes these gas sensors in several varieties: CO2, alcohol (for breathalyzers), ozone, and “air quality” (several gases). They look relatively uncomplicated; anybody know what it would take to hook one of these up to an Arduino? Via Fashioning Technology.
I love this modern twist on a traditional cross stitch sampler from Sailor Coruscant. It’s based on a pattern from LiveJournal user, Gnat, with a slight modification in how she displayed the alphabet. She used the keyboard “qwerty” configuration to give a simple, perfect personal touch to the sampler. I love the details of the […]

Robert Hart is developing his own cosmic ray detector using familiar fluorescent tubes and a high voltage(~650V DC) power supply. The design is a variation on an example from CERN researcher Sascha Schmeling’s DIY Spark Chamber – Like the CERN example above, when a muon flys through the fluorescent tube, the gas inside ionizes due […]
From the MAKE Flickr pool Carl decided to test the limits of the Open Source Electronic Game Kit by letting Arduino give it a go. He wired it up for proper control and after three hours of chip versus chip recorded the following … Apologies – I suppose that’s a bit of an ending-spoiler for […]
