thank you.....but can you tell me what kind of questions they can ask me about.
I hate 2 questions they always ask:
1. What is your strongest courses to handle this job.
2. What is your weakest courses in these strongest courses, and why?
thank you again..
nextgen job interview
I have an interview next week for this position. Any comments and advises are greatly appreciated.
Description
Design Verification Engineer working on the next generation large VLSI to be used in continuously available hardware. You will start on an active team...
i used this chip
**broken link removed**
but other country make it, they called 7667,input is pin2, pin 2 connect with pin 3 by one resistor, pin 3 also go to ground, pin 6 go to Vcc, pin 7 is output to trigger the mosfet....can i replace this chip by LM358, it's just amplifier the signal....i...
Yes. Actually, I built the circuit exactly you posted, but the output is so small, can not drive the power resistor and inductor.
The driving circuit I built I used the schematic LM555 National Semiconductor as Figure 4 and Figure 1 to trigger the Mosfet. The output from Figure 1 is low, I...
chopper lm555
I have a schematic which I'm doing right now, but something is wrong with the connection. Say, Vcc has to connect with the Cathod of Diode, and Anode connect with Drain, Source is ground, the output is between freewheeling diode...but I get the output just around .4V with input...
lm358 driving power mosfet
I need help to finish this project. I used 2 IC555 as Astable and Monostable to trigger the MOSFET IRF620 n channel, I can also change the frequency and duty cycle.
I got two problems.
1/. The output signal is small when compare with input voltage(~50V), can the...
Re: chopper need help
can you give a link, i cant see that
anyway, i tried to search on google but i didnt work much for me
i want a circuit to build Class C two quadrant chopper with adjustable frequency, without specific requirements, any output is fine for me
thanks
Re: help me on power supply
Thanks for your help.
But Im still need help for relay.
Is it DRSPST5 from the website https://www.futurlec.com/RelDip.shtml
Re: help me on power supply
jzaghal, I'm not sure I can understand how come I change relay to 5V, and it works for circuit. Can you explain more details.
Actually, I just want to use that circuit to activate a small alarm. The power is just 2 AA batteries or 4 AA is maximum. I can not get 8...
help me on power supply
**broken link removed**
for the circuit VOX above, power supply is 12V
but I just have 3V, or 6V maximum. Can it supply that circuit. If not,how come I do it.
thank you.
Re: sensor question
nope, you are misunderstood me
What i'm trying to do, I need one sensor to mount on "the walker" (not on people) so the disability people use it, it will activate the LEDs because this user is deaf(he can not hear at all, but he can see). I think I will use one IR...
