hey im new to the group and i am interrested in using my basic stamp II kit to make a simple guitar petal. i was wondering if this is possible and if so, if...
The circuit does not reset when a non-inductive load is attached to the TIP -- only when the motor is attached and only when I use the TIP that I over-amped. ...
Yes, they do, but the LTC and what you replaced it with may not. Always double-check your connections when making any substitution. I've also learned to...
There is an eplenation in the manual and help file. The PWM command is designed to be filtered in order to create an analog output. It is different from PWM...
To get started, and for those of us who don't play, exactly what do you want the guitar pedal to do? Ken ================== hey im new to the group and i am...
Yep, a new month and a new project. Something to help you debug that intractable Stamp program this month... As always, http://www.awce.com/som.htm Enjoy! Al...
... While you can do some things with the stamp for guitar effects, I question the applicability, even from an experimentation standpoint. Most effects pedals...

The BS2 doesn't have near enough horsepower to do any real-time audio processing. That's why pro-audio gear uses dedicated Sharc DSP (Digital Sound Processing)...
... Good write up. The old manual under Basic Stamp 1 App notes, says that using the circuit, they got up to about 15 minutes of an output for a single burst...
Hi everyone, is that possible to do a kind a PWM with a 555 controled by a BS2 is anyone did before. I want to do a motor speed controler. Regards Chris...
It depends on the load placed on the circuit. We recommend using an opamp buffer as shown on Tracy's web site. -- Jon Williams -- Applications Engineer,...
It might be fun to find out. Connect the 555 as a VCO and use the PWM filtered PWM output to control it. -- Jon Williams -- Applications Engineer, Parallax --...
... You could bounce a laser pointer (LED) off of any part of the rotating shaft or chuck and use a photo detector to count the pulses. ... Actually, if there...
... I don't think the stamp has enough juice to do DSP but it could act as a MIDI interface to analog FX circuits. -- Enjoy, George Warner, Schizophrenic...
I am trying to read NMEA data being transmitted from a Garmin 35-PC GPS unit which is sending a standard GRMC sentence every second at 4800 baud to my BS2p40...
... What benifit would you get with a 555 ? It seems the PWM in not a perfect duty cycle, but makes the full count come out right over time. For motor...
Maybe your data is getting double inverted. Remove your MAX232 or change the baud rate parameter to 500 for 4800 baud on the BS2p. -- Jon Williams --...
... I'm not sure I follow. The op-amp would be the end of the loop for the Stamp output. the R and C in the signal line from the Stamp would never see any...
Jon, I tried the 500 baud rate parameter as well as every other one listed for the BS2p with no effect. I have the max232 there to convert the incoming GPS...
... I was going to suggest a method that involves using two Op-Amps. One generating a triangle wave, and the other acting as a comparator. The Triangle wave...

If you have an RS-232 level signal then you can feed it to the BASIC Stamp through a 22K resistor (protects the pin if it accidentally gets made an output)....
Jon, Hurray!! It works!!! I used the 22K resistor like you suggested and its working fine. Last question. If I want to send data to the GPS unit (ie. to...
Hi Dave, With a good CMOS input op-amp, the hold time can indeed be minutes. There is a leakage current which depends on the op-amp, the BASIC Stamp input, the...

probably the simplest thing to do with the stamp and FX pedals is to simply use the stamp to turn on a certain combination of pedals with the click of one...
That part I don't know ... haven't tried it yet. Chances are with very short connections between the BASIC Stamp and the GPS unit you can get away with not...
Actually, with a 22Kohm resistor in series, the Stamp quite happily can recieve RS-232 signals. The Stamp has internal clamping diodes which prevent damage to...
