Ciao John, I'm working on a project that uses the 82C54 PIT with the BS2p24. To solve the problem of the excessive I/O required by the PIT I use two PCF8574...
Hi All, I can't seem to get a 24FC256 EEPROM working. I can't find any code examples specifically for this device, but it ssems as if code for the 24LC256...
Jonathan: I've connected a stock BS2 to a 24LC256 so I can't imagine the FC version (which seems only to differ in the upper end of buss speed) won't work....
... voltage circuits? Is there the possibility of some form of disturbance in the watchdog circuit of the stamp if near high current circuits switching on or...
Jon, Happy new year! Did your clock count down ok? Were you awake to see it ;-)? Thanks for the NV link. Oddly, cutting and pasting from this PDF seems screwy....
I am a beginner in basic stamps. My question is how to detect a disc in kwh meter, number of rotation and convert it to cost in seven segment display. ronny...
You can get the files from all of our posted N&V code on our web site. Using the menu bar, GOTO Downloads --> Nuts & Volts Columns and look for the article;...
If you can't come up with something more suitable, you could roll your own counters using a PIC. The PIC18F252, for instance, has three built-in, 16-bit...
I'm not sure if you have to use the electric companies power meter for your project. If you must then use an optical sensor. most disk in kwh meter have holes...
If you do have access to the disc and can put an optical sensor over the slot/hole, perhaps using PULSIN would let you get an "instant" power reading. The...
HSC Electronics www.halted.com sells these 24 pin LIF (low Insertion Force) sockets for $0.79. They are big, almost 1/2 inch tall, but they are perfect,...
My common sense tells me that my questions must be already be answered and written up someplace, but I couldn't find them. For the BS2: First, the spec says...
John, I have used a stamp directly from the vehicle battery several times, and despite the noisy evironment I have not had trouble. The 0 to 12 volt signals...

Hi Everyone, I want to build my own modules that plug into the Appmod port on the BOE but I'm not sure what type of connector to use. I'd be soldering the...
In a message dated 1/1/2004 6:22:56 PM Eastern Standard Time, ... Your best bet is to buy one of the blank AppMod boards from Parallax so you can see how they...
Hello, In my recent order to www.jameco(part# 174043), I bought a few latched hall sensors to play with. There is not much on the jameco site for the product...
... For my robots, in the making, I want a web interface. No graphics. Nothing fancy. Just simple text so I can give them instructions via the 'Net. I am...
Curtis, I assume you want to interface the part to your stamp...... Connect pin #1 to +5 volts. Connet pin #2 to ground. Connect pin #3 to +5 volts THROUGH 10k...

Hello Chris: Very nice project, the CdS sensor is a neat idea. I'm working on a similar BS2 project for a digital camera, but am hung up on how to use a...
Hi, I've got the Al Williams book on this so I know it can be done, but there arn't example programs for it? Could anyone please help me out with this? I was...
I'm looking for a laser distance sensor to rig up on a pan-tilt mount to create a cheap alternative to those extremely expensive 3-D imaging systems, but...

I'd probably check out the hall effect sensors at www.allegromicro.com The data sheets are likely there as well. Plus they have a lot of other info as well. ...
Guys out there, Happy New Year. I am currently doing a project which need to use basic stamp to drive a few servo motors. As I am quite new in this field, I...
