Hi. I am trying to use amplifier in a projekt like this Shouldn't this be posible with this kit? (read: it dosn't work yet :-) )
Asked by: Sophie Hovdekorp

Hi Sophie, Unfortunately we have never tried this amplifier with a fabric speaker. In theory it may work, as this kit is an amplifier kit and would work in a standard project for amplifying an input.

Hi Can this kit be used instead of the DIY Speaker Kit required on the Micro:bit air guitar?
Asked by: LeonL

Hi, Unfortunately as this isn’t a kit that we have developed we can’t confirm if this amp kit would be suitable. You would need to find out what amplifier is used in that kit and then find one that is equvilent.

Hi would it be possible to connect the power supply to a light sensitive sensor that when covered plays the tracks from the mp3? Also would it be possible to connect headphones rather than the speaker? This for an exhibition piece I would like to create but i'm not overly gifted in the electrical/technical side of things yet.. Cheers Em
Asked by: Emily

Hi Emily, The easiest way to do this is to connect the power to the following kit, 2112-light-activated-switch then connect the output of this kit to the power of the mono amp kit. This would then mean when it went dark or light (depending on how you connected it) the mono amp would then be on. You could also connect headphones to the amp kit but you would need to ensure impedance rating is 8 ohms or higher.
