Re: Simple Remote control
The code that accompanies the article is for reading the remote from the PC. But the signal it produces is just a signal. You could use it to trigger anything. I just happen to be using it to trigger a PC serial port's handshaking line. In fact, I've used the same setup to trigger a relay and a Basi...

Re: Simple Remote control
The article I mentioned doesn't use a PIC or a Stamp and it is RF, not IR. It is just a hack of a cheap piece of radio shack gear. I'm not sure where you got the idea it was PIC/Stamp/IR related.

Re: Hints for a rookie writer?
I'll weigh in. I have made part of my living from time to time as a magazine columnist or editor (editing generally pays better). However, I've never been able to make much money writing electronics articles and have stuck mostly with software development magazines (Dr. Dobb's, Web Techniques, Visua...

Re: White LEDs
You need a dropping resistor. Computing the value depends on the voltage of the LED, the battery voltage, and the current you want to drive through the LED. An exercise in ohm's law.<p>If you want to learn more about all of this, check out http://www.al-williams.com/classroom/course/view.php?id=4.

Re: RS-232 control of light bulb
Speaking of the Firecracker, if you can get these cheap (they have, at times, given them away for shipping) they make a great interface for the BS2:

If you are looking for some guidance on Eagle (or toner method or even outsourcing boards) look at http://www.nutsvolts.com/Store_Pages/Books/buildYourOwnPrintedCircuitBoard.php .<p>The free version of Eagle is very capable. They do want money if you use it commercially or you want to do larger or 3...

Re: LED Sequencing
A PIC could do this. However, if you are just getting your sea legs in electronics, you may find the Basic Stamp easier to work with. They are at http://www.parallax.com . I maintain an unoffical Basic Stamp FAQ at http://www.wd5gnr.com/stampfaq.htm .<p>If you do want to work with the PIC (or an Atm...

Re: Reading servo signal from JR receiver
I doubt the Stamp can read fast enough to get both sides of the square. So you are actually skipping some parts for example: <blockquote><font size="1" face="Verdana, Helvetica, sans-serif">code:</font><hr><pre> --___-----_____-----____ A B C D </pre><hr></blockquote><p>You might...

Re: RS-232 control of light bulb
More overkill for your application, but you could use the controller at [GP3] and a solid state relay or a mechanical relay to do the job. I've used them many times with SSRs but usually we need to control several. The board has libraries that are usable with Visual Basic, Java, C/C++, Linux, or eve...
