Is there any C code for ATMEL's AVR micro controllers to read servo motor
position data from a serialport and control 16 RC servo motors
simultaneously?

I guess this question is addressed to anyone who has used one of these
successfully.
The device is an H-bridge driver with separate inputs for each
channel.

Yes that's right, HP inkjet printer cartridges.  Need to know what the
circuits are on the cartridge from the contacts to the print head.  Tried to
meter this out and it's not making much sense of the readings using an ohm
meter.

Hi group.
To reset memory on the Casio WQV-1 watch camera :-
1) Put into watch mode
2) Press bottom left (mode) once "Play"

It just occured to me, why dont IC's come with internal decoupling
capacitors ? as its suggested to have them as close as possible etc
etc.

I want to make a 10 meter long usb cable, I need to be able to connect my
telescope digital camera to a desktop pc, all the current cables in the
shops only go upto 3 meters. Is there somewhere selling the connectors ?

How to build a phase detector??
I know that normal design is two flip-fops and NAND gate but it works only
with phase difference between signals smaler than 1 (T).  How could I
possibly build a phase detector when phase difference between signals is up

I'm doing a project in clockless uart..as u know that the primary
function of uart is parallel to serial conversion while transmitting
and serial to paralel conversion while receiving..I was wondering if
someone could tell me as how can i do a parallel to serial conversion

I'm trying to program a PIC16F826 with a JDM programmer ("Multi chip
programmer" from http://www.talkingelectronics.com) and IC-Prog 1.05C.
I always get the error message "Verify failed at address 0000h!".
Anyone know what the problem can be?

Please can anyone help me with a circuit that can automatically
control the humidity in a poultry incubator? A complete step by step
or DIY on how to build an incubator is welcome. thanks

I was wondering if someone knows how to do this. There are adapters from
PS2>DB9 normally intended for mice, but I have a reverse situation:
I need to connect a RS232 device (specialized digital modem) to a laptop
only equipped with PS2 port.

Can anyone tell me where I can find a SPICE or a PSPICE model for a 2N3055
NPN transistor. Any help anyone could provide would be greatly appreciated.
Thanks in advance,

I've heard of special pens that containing conducting inks. They were
mentioned to me as a way of drawing printed circuit boards and not having
to worry about etching copper. What I'm wondering is whether the inks
that go into these pens are available in containers other than the ...

Where I live, the electric co. ran 2 wires for 240V. There is NO
common, each leg is 120V. When I try to use one leg for 120V and add a
ground for the common, the 2 lines become unbalanced and one line may
read 80V while the other reads 160V. What can I do to  fix this

   I have a collection of DVD's which i would like to backup. I have tried
