Re: Using DTMF to drive solenoids

Hi John,

*** This is an email I sent you because I guessed it's not possible to post
pictures to this newsgroup. Did you receive it? ***

Thanks for your help so far!

Actually I am not going to drive castagnets; I am going to drive
"crab-arms"!  Together with my girlfriend I am building a synthetic "plant"
equipped with 16 crab-arms. The plant should be able to give a concert every
once in a while. The attached picture shows a small test-model we built; we
emptied the crab-arm and equipped it with a solenoid from a pinball machine.
(This "prototype" is push-button operated but it works really well.)

My knowledge of electronics is quite basic but I can understand your
schematic fairly good.
I will try to find suitable solenoids.

Do you have any other useful remarks before we build the schematic? Of
course we'll keep you posted concerning the result!

Thanks again,
Eibert Draisma.
