Tinkering -- October 24th
Had our usual weekend tinkering this Saturday. Breaking News: We got our own Slurpee machine! Some highlights: Got a slurpee machine! SuperProbe manufacture Making the DSO kits we group-ordered Made a prototype drumkit for future workshop stuff Juggling & Poi practice
I came across the Super Probe two weeks ago, and just had to make one. I had a bunch of the PIC 16F870 microcontrollers left over from an earlier project, and the rest of the parts were all easily found in my parts collection. It is a really simple circuit, with so many useful features: - Logic Probe (L 3.7 V, P > 0.5us pulse) - Logic Pulser (0.5 us pulses at 5, 50, 500, 5k Hz) -...
Geigerduino (part 1)
Over the last couple of months, Gav and R3becca have been discussing a new project idea - the Geigerduino. The idea being to be able to build an simple device that can detect cosmic rays or other radiation using a Geiger-Müller tube and an Arduino, and then publish the details so others could do the same. In late August, whilst having an R&D group dinner at Rockdale McDonalds, Gav quizzed me...
