Need help - Computerized Scale
logitec replied to logitec's topic in Electronic Projects Design/Ideas
the only problem is that im from israel and i dont have a place to buy it :-[ and about programing in vb , where can i get information about that? -
Need help - Computerized Scale
logitec replied to logitec's topic in Electronic Projects Design/Ideas
well i dont think i could use any other scale but digital and writing a program that i will be able to show the information in a graf i think it is hard spacialy when i have never programed any thing program-hard ware -

any one? -
Hello . Resently I have started geting interested in modifing a scale so I will be able to see a graf on my computer of any wight movements. I saw here some when a thermometer that doing the same can I modify just the parts and use the same program? and as the sensor i will use a usual human scale? tnx Ron some thing like this one http://www.electronics-lab.com/projects/pc/013/index.html

hello agin i have started building this project and i have left one capistor not in use where does it satnds? C10 electrolitic 10UF ron

hello MP I did some reading in this post and i saw a few people that had problems with this project hello audio can you tell me what difference and corrections those parts are making i mean why have you changed these parts
-
hello all i see there are alot of mistakes in this project (almost 60 pages) can any one tell me what i need to know to build it, problems and what was discussed Ron

TNX i didnt thought about it

yaa i can find the 0.47 Ohm with 10W (the only one i found with this resistens was 0.128W :S)
-
ammm what wre the pots and trimpots?
-
oooo i just came from the store :'( any way can you tell me more about the changed parts why changing them and in what are they better? and one thing more i can install a cooling system (2 computer fans, intake and outtake) that will help? Ron

a fue more questions: -can i use 1N5408 diode in the place of D1, D2, D3, D4 where in the circuit was writen to use the 1N5402,3,4 diode 2A - RAX GI837U -what is the diode that is writen on it 1N 75 2A 227 and can i place it as D7, D8 = 5,6V Zener diode -can i put 1N4007 diode instead of D11 = 1N4001 diode 1A - how much Tolerance can i give to the R1 and to R7 Ron

need help designing a power supply 3.6V 10A
logitec replied to logitec's topic in Electronic Projects Design/Ideas
that isnt a problem and what out put it has? by the way i cant find this part at the main importer in the country so i dont think i can get it... any other more common parts? -

logitec replied to logitec's topic in Electronic Projects Design/Ideas
OK but steel i need some thing to hold the voltage and then regulate it so what chip can i use that will not burn under 10A? -
need help designing a power supply 3.6V 10A
logitec replied to logitec's topic in Electronic Projects Design/Ideas
the input voltage is 4V not 0.4V and the out put3.6V and i dont think that in my place so new components will be available to me so lets go to the other way we can do this transistor + resistor but the voltage will be juppy after the transformer so i need another chip so lets say stablize to 4V from 5V where can i get one like this? and witch transistor and resistor i need? -

logitec replied to logitec's topic in Electronic Projects Design/Ideas
hello EdwardM i actually meant a chip like 78L05 that stabelaizes 5V of a circuit with exact parameters and tranzistors -
hello all im searching for a circuit of a small triger the when a pin from my microcontrollor will set the first time high the output from this Circuit will be always high no matter if the input is 0 or 1 logical opps i think it isnt the place for this massae sory Ron

how much watt i need for the transformator ???

hii all i am trying out this project: http://www.electronics-lab.com/projects/pc/020/index.html i have already prepered all the electronics to go(Im using the LPT port) but the program while i was trying to download it its site was down while the second program is only for COM ports... can any one plz upload the first program to the site? Ron

hii i have a question 82 Ohm 0.47 Ohm 1.5K 3.9K for what they are used in this project and can i change those to some thing else more common resistors- even the shops dont have them is their stoke and does it makes big difference if i put polyester condinsator instead of the ceramic ones?
