... First off, if this is for some sort of lightening protection, forget it. If lightening comes in the line, it will jump the relay contacts as if no gap is...
just information for European Stamp users: the XM10 interface can be addressed from the stamp with the Xout command, it was just some weird problem with the...
Thanks Jim. You bring up some good points. A little more detail on what and why I am doing: I want to disconnect the phone of my girl friends 15 year old ...
I would find a latching mechanical relay that requires a short pulse to switch it one way or the other. This way you would not have to supply power to the...

Hi guys,,,, Thanks for your suggestions, and stop fighting amongst yourselves.Its not worth it. I simply wanted to know how to use the pot command to speed up...
... Hi Jim, While no guarantee, I do think that relays can provide significant protection. After all, very few hits are direct, and a relay with an isolation...
... I bet Radio Shack has what you need. Since you're not looking for isolation from lightening most anything will do as long as it's at least double pole....

I have a program that runs fine on a BS2P40 in program slot 0. But if I load this program in slot 3, and call it from slot 0, the results are incorrect. I am...
It should work the same as the other BS1 variants. I would first figure out the POT command by getting a value to display in the DEBUG window. If the value...

Hi all, I'm trying to get a TCL1549 10bit ADC to send data to my bs2 with no real success. I had it working with an 8bit ADC0831 (ala' basic stamp lessons...)...
Greetings all! I'm working on a little science project in which I need to use piezo's to trigger variable voltage inputs on a stamp. I've got a 2P right now,...
Dear Friends: I have a problem, I want to work with floating point numbers and negative numbers. I found some nformation in PBP manual about negative numbers...
If your numbers are limited in range you may be able to scale them using fixed point math. So, suppose you want to compute .02 * 6. You could scale by 100 so...
Hello, I have some troubles in linking two stamps with RF Trasceivers, the stamps hangs up when i use the serin with wait formatter (using the Reynold...
Hi folks! I'm using a BS2 on a Super Carrier to control a BS1 Rev.D, which in turn controls a couple of relays that turn LED's on and off. All of the...
Greetings! Also, the BS2 series allocate RAM to variables on a 'biggest first' base, so it allocates Word types first, then Byte (and Byte arrays) before...
Thanks to those who helped with my problems with the tlc1549 10bit adc. I am now getting legit data, and the problem was simply that there was overflow to my...

Hi, I am trying to count inputs for the BS2. What I need to do is set up a timer for say 10 seconds. If the input receives say 3 low's in 10 secconds then it...
