speed control

Hello group,
I am building a project that uses a shop vac as a
blower, I need to be able to control the blower speed
with the stamp (bs2sx). Does anyone have a suggestion
on a 115VAC ( 11 amp) motor speed controller circuit
that would work and the stamp could manipulate? The
circuit could be stepped, ex. speed low, medium and
high, or it preferably would be stepless and the stamp
could vary the speed to any rate. Whatever the
circuit, it must be able to be controlled by the
stamp. Thanks in advance for your responses. Have a
great Christmas.

Scott Sutton

    If you are using a universal motor (which most vac's are) you can rectify
    the AC and control it as any DC motor. Just expect the brushes to wear a
    little quicker than usual.

    Hi everyone,
    I have been in the middle of reading a book on PIC microcontrollers
    until I realized that most everyone is using STAMPs. Being 17 years
    old, I don't have the money YET to buy a microcontroller so I wanted
    to learn the basics of programming and electronics before I invest in
    an actual unit. Is it easier to learn programming and electronics on
    microcontrollers or interfacing with a PC? I just learned a little
    bit on Pascal programming and I just wanted to know if anyone could
    teach me or know of any sites that could teach me how to make a speed
    control using pascal and a 486 (sorry, I know its a little off topic,
    but I am REALLY new to electronics and the digital world).
    Thanks,
    Tei

    Pascal no, but other languages definitely. The problem is even to control
    stuff from a PC you need electronics hardware which costs money. For
    example say you wanted to control some 110v lamps and make them blink or
    something like that. You can't just plug the lamps into the PC. You'd need
    some type of interface circuit which would most likely would connect to the
    parallel or serial port. If I were you I'd save up and buy a Basic Stamp 2.
    I started using basic stamps when I was 15 and based on my experience it's
    the best way to learn. Stamps are also a very good way to get some basic
    understanding of programming microcontrollers. Stamps use a subset of Basic
    know as PBasic which gives a lot of control but handles a lot of the
    difficult aspects of programming for you. PICs are actually very commonly
    used but PICs have a little bit of a steeper learning curve then the stamp.
    They maybe cheaper then the stamp but unless you know assembly you'll end up
    buying a C or Basic compiler for the PIC.

    So in short my recommendation to you is save up and get a Basic Stamp 2
    starter kit or the StampWorks kit which is even better but it's expensive.
    Then once your comfortable with electronics and programming move onto PC
    interfacing if you want.
