I am looking for a specific recommendation of hardware and software
within the PIC, BASIC Stamp, etc.,
single board microprocessor products
that will allow me to trigger (i.e., send
an ASCII string) and then take the
continuous output from an electronic
gauge via RS-232 and display it on an
LCD screen. I get overwhelmed with all
the choices of available products. I
would presume to program in some
form of Basic or C (preferably Basic).

I'm looking for a schematic for a
low power wireless switch. Something
simple, using transistors, with a range of
25-50 feet. Both the transmitter and
receiver should be battery powered
and act as a simple switch.

Our club was vandalized several
times in the last month. I need to put a
video camera at the entry way and turn
on a video recorder using a motion
detector to record anyone who enters.
A commercial motion detector security
camera with a 12 minute digital video
recorder made to look like a clock is
available, but costs $180.
Does anyone make a cheap digital
recorder (recording on an SD or similar
card) that I can trip using a standard
motion detector and which can turn off
when the motion detector sees no
more movement? I can use a pinhole or
similar camera as the video feed so
the video source is not a problem.
Battery operation of the recorder
would be a plus.
I would like to use an old 12 inch
B&W monitor (RCA connection a Dell
Optiplex computer) to show text
parameters using this as an EMC CNC
Can I do this? If so
I'm looking for plans to replace an
old Dranetz 626 meter (records AC
power spikes, voltage drops, and their
pulse widths). I'm hoping someone may
have something that can provide the
I would like to see a design for a
variable frequency drive to operate
single phase 110/220V induction
motors in the 1/2 to 2 HP range. I
think this would be of interest
