Re: Stamp vs PIC microcomputers

Rodney,<p>You can get a PIC kit which includes the programmer, assembler, the PIC, sample codes, and literature at Carl's Electronics for $17. I built the kit in 30 minutes and within a few hours I learned assembly language for the chip (the one Harold mentioned) and wrote my first program. I downlo...

Bipolar Transistor Cookbook

In Ray Marston's article "Bipolar Transistor Cookbook" in the July 2003 issue of N&V he shows the current flowing through the transistor in the direction from positive to negative.<p>I thought that positive to negative modeling of current flow was antiquated and prediscovery of the electron? <p>Why ...

Re: Bike spedometer

Isn't a PIC (Stamp or whatever) required to run a LCD display? It seems that no matter how you arrive at the speed value you are going to have to run the analog signal through a PIC to be able to display the value on a LCD.

low frequency tone generator

The audio frequency of low A on a piano is 27.5 Hz.<p>When I use my function generator to send a 27.5 Hz audio signal to a speaker, the speaker just clicks in and out at that frequency. It isn't until I increase to a higher frequency that the speaker starts to produce a "tone".<p>Two Questions:<p>1....

audio frequency oscillator w/ meter

Is there an inexpensive kit or assembly for a low voltage variable audio oscillator ( 0 to 5000 Hz) with a frequency display? <p>I really "need" one, for alot of different hobby projects I have going on right now.

Re: Composite Video Output

Thank you for your reply,
that is a neat gadget, <p>But... I need to go from my VHS camera straight to a computer monitor without a computer. I need some kind of converter that converts a vhs camera signal to somthing I can plug directly into my spare color monitor. <p>Do you have any suggestions?

Composite Video Output

Hello,<p>Is there a cheap device available (not a PC!) that will convert the Composite Video Output to VGA. I would like to hook up my VHS camera to a spare PC CRT monitor I have. <p>Thank you for your suggestions.
