Hi, I am more electrical than mechanical, I have an application which need to be modified, the current machine checks for axial and radial runout on a crankshatf, specifically on something that is called time gear or time cogwheel (sorry but english is not my native language) the case is that...

Ok, just giving you a more detail on why I need to a delay routine in usecs, I developed an RS232 interface to be connected to COM1 using DTR/CTS (Data Terminal Ready/Clear To Send), RTS/DSR (Request To Send/Data Set Ready) as control lines to drive a 24CXX Serial EEPROM (I2C bus type). So far...

Hi, I have a chaallenge of generate a microseconds delay in Visual Basic, I know how to generate delay on the order of milliseconds (see below) but is too long for my application. Does anyone know how to generate this microsecond delay on Visual Basic 6.0. Thanks JM

Hi there, I have an application in which a crankshaft is manufactured, lately defects have been found on several pieces, the defect is less material as is suppose to be (i have some pics if someone need to take a look), I need to sense in some way to ensure that the piece is always...

Hi, I am experimenting with a programmer for 24CXX type serial EEPROMs, I developed a programmer interface for the serial port (I don't want to use the parallel port which is a common preference) on the PC, I have tested this programmer using PONYPRO program and works just fine, the thing is...

Hi, I have downloaded from the net a programmer that uses serial port from the PC, also i downloaded different applications to programm the serial EEPROM (in my case I am using a 24C01 (1K EPPROM) I am able to read and write using these programas which tells me that I aseembled my programmer...

Hi Hold timemay vary, it could be 1 sec to anytime, the rule is if I start IN1(ON), ramp goes up from 0V to 10V when IN1 (OFF) 10V are hold until IN2 is activated (ON) and ramp down from 10V to 0 V, the slope going up and down is the same 1V/sec means that after tens steps i will reach 10 V if...

IRStuff I wonder if you can provide more details on your comment to work it out. Thanks

Hi nbucska, which software you used to simulate circuit? I am having trouble interpreting files you send me one seems to be truncated. I you could email me directions to interpret how to build it from node list i will aprecciated. JM

Yes nbucska wire list will be ok to give it a try, if a doubt arises I will posted for your help.

Yes, you are right, any other change won't affect the operation nbucksca, let me check the circuit you just send me. tks JM

Thanks IRStuff I willwork on your tip, everyone: IN1 and IN2 are exlusive, means that when IN1 is activated ramp is going up and IN2 is not present, when IN2 is activated ramp is going down and IN1 is not present, based on IN whenever they reach their correspondig target they will remain on that...

Thanks nbucksa, I have the timing diag how do I add it, sorry but I am new to eng-tips.

Hi everyone, I have an unusual application in wich I need one Output (OUT1) and two input signals (IN1 and IN2)in a circuit, the input signals will provide +V (+24V) or will be open (lead lifted not grounded) depending on certain conditions: 1. IN 1 = +V, when this happen a Step Up voltage...
