  • Long range, 1.8km,  Arduino to Arduino wireless communication with the HC-12.

    Don't know who this "range" request is for, but my response is that it depends on the RF environment, transmitter power & local band noise ! LoS (Line of Sight ), with simple ~165mm wire whip antenna & elevated I managed a good 500 metres with controlling PICAXE's at both ends. However at ground level thru' typical urban clutter (mostly wooden buildings here in NZ) I was lucky to get 100 metres. The spring antenna in my trials was NOT as good as the wire, so you'd perhaps max a few 100 metres in open space & under 100 metres in built up urban areas ( less if solid walls & conctrete etc).If you want more range then I can HIGHLY recommend Semtech's LoRa™ technology, which give km instead of 100s of metres.

  • Discover Electronics With Snap Circuits Arcade (A Review)

    Bravo - although indeed a tad costly the Arcade's POV display should REALLY appeal to youngsters! Quite some years back (~2008) I PICAXEd a basic snap kit's sound module to very good effect. This proved cheap, versatile & very educational. See =>http://www.instructables.com/id/quotSnap-connectorquot-PICAXE-microcontroller/

    Bravo on posting this - the whizzing POV display should REALLY appeal to youngsters! Quite some years back (~2008) I gutted & PICAXEd snap kit sound modules to good effect. See=>http://www.instructables.com/id/quotSnap-connectorquot-PICAXE-microcontroller/
