Please help me, I got problem.
From circuit diagram
Target : I want to make square wave on Vout (Period =18 sec on :8 sec off: 10 sec)
I have problem when I use scope to measure triangle and Vout , I have followed target. But when I use scope to measure Vout only, time Period and time on reduce...
I have a circuit that
produces 2 pulses of (200mv)-(2v) when transitioning to On state
and
produces 2 pulses of (-200mv)-(-2v) when transitioning to Off state
I have would like to use these pulses in the simplest way possible to control a switch/relay/circuit
+12v on state
0 volt off state...
Hello, I am engineering student in Turkey.
Our teacher gave us a homework. I took care of all but this question. But I couldn't do this question. It is very complicated, I just could not put it in my mind. Can you help me?
Thank you
Hi everyone, can you help me
I want to make a alarm circuit when the power failure or outage. Relay detect a 220vac in normal close, so when 220vac it’s fail , relay can detect and buzzer is alarm until press a reset switch.
Hi All
I work for a medical diagnostic company which develops drug/malaria/HIV/etc diagnostic tests. I have been tasked with the role of learning and developing a digital display to mitigate human error when reading the results.
I was guided to look at the ClearBlue pregnancy test (with LCD...
Hi, guys, I'm new here. Recently I made a design of TPS54116QRTWTQ1 based on the datasheet. According to my design parameters, the actual voltage CPUVCC15 is 1.5V, VTT_DIMM is 0.46V and VTTERF is 0.86V. But the voltages of VTT_DIMM and VTERTF are not correct. When I remove the load behind...
Hi,
Our Trademark is currently designing a pair of "Powered heated Winter horse riding boot".
We are looking for someone with experience to customize the right heating element/battery/selector etc.

The code is here,
Diode Voltage Drop
r1 1 2 10k
r2 2 3 5k
r3 3 4 4k
r4 4 0 3k
vin 1 0 dc 10
.print dc v(3,2)
.end
As you can see I am trying to get a voltage drop between node 3 aand 2. But the print function is not working properly. It is just showing the usual outputs of( the ouput is...
I have a project, first i need to find a circuit to Analyse/study the Frequency Response of Heterojunction Bipolar Transistor. Then simulate that circuit on SPICE (i'am using Orcad Cadence).
Can someone help me finding a circuit as mentioned above???, I'm having difficulties finding one. Any...
Any help on this problem would be very appreciated:
So I am supposed to solve a push button problem and draw the circuit, using any gates and multiplexers.
So the problem reads:
Design a sequential circuit which will output Z = 1 for exactly four clock cycles each time a person pushes a...
Hello everybody,
I am planning on making a motorized Pan/Tilt head to go on a camera jibcrane. My electronics knowledge isn't too well, so I'd wanted to ask all the amazing people here.
My plan was to use two 12volt DC motors, powered by a battery pack, to drive the axis, controlled by a...
