Re: Pic Programmer kits
There are lots of options. <p>One way to get your feet wet without a lot of expense is to use a boot loader. I agree that the 18F series is the way to go if you are just starting, but, the 16F has lots more example code on the Web.<p>The problem with a boot loader is you have to know someone with a ...

Re: transmitter / receiver
Have a look at a wireless doorbell. Read http://www.wd5gnr.com/rfrem.htm for my experiences hacking one of these for a laptop "clicker." I've also used them to let one Basic Stamp send a signal to another.<p>Hmm... 300 yards? Thought you said 300 ft. Not sure if this would do it or not for...

Re: Schematic CAD program?
Actually Eagle has schematic capture and PCB routing. I often use it just for the schematics.<p>I have a recent book about using Eagle which covers a lot of ground including schematic capture, PCB, routing, how to make your own boards, and how to have them sent out... <p>Whoops that's the wrong link...

Re: Microcontrollers help
There are many books on the PIC, but there are also many tutorials on the Web. Mine is at http://tutor.al-williams.com although if you google for microchip pic tutorial you'll find a bunch.<p>The PICs are very cheap and a bewildering range of parts. AVR has a more sane architecture, but are have not...

Re: basic stamp2 to start a timer
In general, yes. The Stamp is not fantastically accurate over long periods of time, so depending on your definition of "timer" you might need to provide a little extra information. A simplistic approach would be:<p>ctr var word ctr=0<p>XLoop: High 0 ' turn on square wave Pause 5 ' pause 5m...

Re: Basic Stamp
There are actually two Williams <p>Have a look at http://www.wd5gnr.com/stampfaq.htm<p>Also, subscribe to the Parallax discussion groups http://groups.yahoo.com/group/basicstamps -- I think that's right. Lots of great info there.

Re: can visual basic control serial or usb port power?
One thing you could consider (although it might be a little overkill) is a GP-3 (see http://www.al-williams.com/gp3.htm). This board can control several digital outputs, has digital inputs, analog input, PWM, etc. You can connect to it with an ActiveX control from VB, VB.net, VBA, C++, etc. This alo...

Re: schools
Challenging is getting more accepted. One problem though is that any ABET certification requires an amount of lab work and I don't know any way around that except doing the lab work. ABET cert may not bother you if you don't plan on seeking a PE ticket, though.<p>There are three kinds of schools:<p>...

Re: Schematic Software
Speaking of Eagle, be sure to check out my latest book. It includes the free version of Eagle on CD and covers using it for schematic capture and board layout. In addition, it talks about creating libraries, building your own boards, or sending them out to a service bureau. Literally, hot off the pr...

Re: Transistor Circuit Needed
I wonder if you need anything to drive the LED but the PIC. The PIC can drive a good bit by itself (maybe 20mA if memory serves -- as high as 30mA on some). Check the data sheet. I wonder if you could parallel two or more output to draw higher current? I haven't tried it, but it should work as long ...

Re: new in PIC assistance needed
Another tutorial resource:
http://tutor.al-williams.com <p>Just recently added some 18F material there to supplement the 16F material that has been there for some time.

Re: Buying a digital multimeter
I have been happy with Elenco for "cheap" meters. They are inexpensive but work well and are pretty rugged. Read: http://www.wd5gnr.com/meter.htm
