Subject: Re: [alt-beam] Re: BEAM sound maker
my advice is to nay luse a speaker. It would drain your energy within
seconds. Use piezo transducers, they have 90% effeciency over 2 % of the
speaker.
or look at wilf's great communcation module using microcore tech.... they
are awesome!
I've attached the printlayout with the components on. cap's are in uF diodes
are 1n4148
use the piezo part and not the green speaker part
I've allso attached the protoboard layout that's way smaller than the
printed circuit.
goood luck!

is there a tutorial ne where to create the sound maker?
thank you for the help
what is a protoboard? im literally a begginer, not even know whatthe
symbols mean yet, so im probly the most begginer you can be.
