anand, So it sounds like there is no conversion between ASCII and Modbus, it's apples and oranges time. Jim

Hello all, I'm trying to build an electronic flute and need a way to create each note from a source tone. I'm using a voice record and playback IC (ISD1420P)to play a looping tone as the source. I

Stan, I don't know what kind of computer languages you know or what you consider cheap but the Basic Stamp modules by Parallax are what I started with recently. They are programmed in PBasic and are

Do you want your VGA monitor receive RF television signals (like channels 2-13) or just make a circut to convert NTSC video to VGA?

iman, So is ASCII, can you say something about where or why it is used instead of ASCII? The first thing you could do is locate a table for both and compare the two. If you had two tables in memory,

Thank's Jim, I just red the instruction,Modbus is a protocol for data tranfering. It's a standard protocol comunication which created by Modicon.Presently i've problem to establish communication

Yes, I meant accidentally, sorry for the missunderstanding. About the spanish pronunciation, you are 95% correct, it goes like gui (like "gi" in "give") ller (like "Jerr" in "Jerry") mo (like "mo" in

Guillermo, Have to get it from someone besides me. I'm neither a physicist, nor an engineer, although I challenge an engineer to explain it. :-) Jim

That's a good one! I would be very grateful if you tell me the answer. Guillermo.

As fuses are used as overcurrent protection devices, the relevant factor here is the CURRENT that the fuse will carry before melting. Power is somewhat irrelevant here, as it would be an indirect way

Sorry but it won't.... Simply because you don't have just the two resistances there... In fact the Op-amp has its own active resistance and i feel that you can read that from any good book on

d, First off, maybe you mean a pass transistor. This approach involves using the regulator to establish the output voltage at the base of a power transistor, then the power supply output is taken from

Back in August I posted a question about building a power supply and someone suggested bypass transistors as a method for limiting current at the input to LM3xx and LM78xx voltage regulators. What are

Here's an idea: Buy a new VCR. Seriously, these things are cheap now. I've seen them for as little as $50. If you were good at electronics and had access to tools and parts I could see fixing it

Hi folks, I just started a Yahoo!Group for us techies in the Portland,OR area. Maybe we can get a group going and try setting up some meetings so we can show our project, help each other out and

Sure, you'll need a few things to get started: 1) A microcontroller (from Digikey, Jameco, etc.) 2) The hardware to program the microcontroller (many designs exist online that can be built for less

Jim, I'm not sure what you meant by this, but, once programmed, the PIC can be placed in its own circuit to perform its duties - its program stays in its EEPROM (or EPROM) and will start running once

Hmmmm. Somehow the problem solved itself. So, it must've been in the software somehow. I thought I blew a hardware connection. But, maybe you can explain the mic in the computer and what happens when

Try this: + | R | *---||--------- Opamp Input | R | - Did you understand that ? I sure didn't :). The point with the negative voltage is to allow the audio signal to swing both ways Now if you're able
