I agree with Audioguru.
Especially you don't know much on the circuit. -
use STV5730 as OSD driver for analog video.
-
You can try using 74HC193, the binary up/down counter and cascade them to counter up to 50.

It is a technology trend in using different buses......
the newest have the higher data flow bandwidth and faster speed. -
Hi Cody,
My soldering iron is temperature controlled and doesn't turn the rosin in the solder to smoke, just pleasant smelling steam. The steam rises in front of me, not into my face. I also seem to hold my breath when soldering, so my hands are steadier. I huff and puff a bit beween joints (solder joints, not the other kind of smoking). ;D
Reminds me of when I snuck some good stuff into the brownies my wifey cooked for her Tupperware party. You should have seen the smiles and those ladies dancing around! He, he. ;D ;D
Try a different brand of solder. I like the smell of English - Ersin but hate American - Kester.
I do approx. the same as Audioguru...... hold my breath while soldering.... and I will not apply paste unless it is necessary.....
More is...... I will blow away the fumes..... when it comes up...... -
why not layout yourself?
2 days is far more enough for this layout............ ::) -
nice pictures..... Sasi.
So how are their performance then? -
unless you are using analogue meter.......digital meter will be able to take the 5V at its negative probe.....

Like audioguru said, only one column will be considered at a time.
At the same time, you can determine which LED in a row will lite.
Each column will state on a very short period of time and loop.
I think it is no more method to make the LED matrix lites as you decided. -
Give a try and use spybot:search and destroy to scan for checking spyware.... you will get more spyware that adaware doesn't show you......
Here is the website and it is freeware

you have to change the phone system.....
building your own circuit is not efficient ... buy one! -
You have to build a rectifier circuit before the two regulator circuits.
Also be caution on the current drawn from each regulators and the circuit behind them. -
Hi Ldanielrosa
Thanks a lot for the knowledge that you shared. I didn't get what does the caster mean. Guess its some kind of wheels working concept.
What does dedicated device mean here. Then how to decide which motor will be suitable.
I will be using a Pentium Processor as said by Prateek. Soon I will be starting to make position control programs for the same.
Thanks a lot
Bye.
Sumit
don't be kidding....... using Pentinum processor will drive you into nightmare......... unless you got an industrial control board based on intel CPU..... else... don't touch it........
and most MCU are sufficient to perform motor controls........
-
My veroboard sample will not as tidy as Audioguru does............ :P
Good job Audioguru!!!
I got to learn from you... ;D -
compare die bonding on PCB and IC fabrication ??
-
I have changed my web surfing using firefox for 2 months.... so far no big problem except some required IE only webpages. And there is no problem in here.
And I really found out that I am free of spyware (I am using spybot:search and destroy to scan) .....
Previously using IE will result at least 5 to 6 spyware installed after a week.... -
Agree tp Ante.....
Open the case may cause more dirt inside.... which may be a disaster..... -
robots is a combination of electronics, porgramming and mechanical monster..... :P
What Kevin refer to is the program codes on the MCU to control the robots. -
ISA is no longer commonly available in nowadays motherboard.... except some industrial mini size controller board
and do not "visually" distinguish the bus .......... get yourself a manual of the motherboard..... it will clearly state what are these! -
For lamp switching, I suggest you to use diac+triac for switching on/off, where you can find many of such circuits in the topics of dimmer switch.
So, is there any meanings on the serial port data? If yes, I think you may need MCU to interprete the serial signals at receiver side .
For transmitter and receiver, I think you can find many circuit in this site and some hot topics within this forum.
The system seems not so complicated, just what you need to do is step by step doing so.... and many experts here (except me :P ) will give you much help. -
If you have block diagram of the system, there is not much difficulties on building each of them.
And what is the problems you are facing in using IR??
Is the lamp are AC supplied??
RF transmitter and receiver? Frequency? AM? FM? Distance?
You have to clarify your mind on these questions (or more) in order build the system.
Remember to build block by block. -
max2606 center frequency is adjusted by the external L... can vary from 45MHz to 650MHz
-
acrobat reader 7.0 can read ps file....
I found it some time ago -
use ghostscript and ghostview to print ps file
Light bulb dimmer

some low cost dimmer will use SCR + diac circuit...
