Hello, I need some assistance identifying this smd component on an LCD inverter.
It is marked DK and then QM right below it. I have another identical board which is a newer revision and the same part is marked DK however with QS below it.
My preliminary research on s-manuals seems to indicate...
I have a problem in my ET212 class that I truly have no idea on where to start, I have the circuit design, but am clueless when it comes to the values that I need to use. I am not asking for answers, mainly just guidance on where I am supposed to start, or the steps i need to do to find my...
So this might be a bit of a strange one i have a LE-375 single board computer nothing to fancy but im planning a little project for it and i got given it and would love to get it up and running on Linux as its not the most of powerful of devices.
Iv contacted the company who make them but not...
Hello everyone,
I made a post before on here (I am new) but I think I posted it in the wrong sub-forum and I got no responses.
I have a Nordic Track T5.7 with a MC-2100LS-30 motor in it.
I have connected an Arduino Uno to the wiring harness that connects the controller to the console like so...
I recently got a NordicTrack T5.7 treadmill which is powered by a MC2100LS-30. It is an older treadmill that works great, however one of the features of the new treadmills out today allow you to visualize your treadmill run like so:
This is amazing to me, but my treadmill is not smart like...
Hi i just joined to try and get a little help after getting no further with my project all day.
my project is one push button and one LED.
my goal was to get the push button to swap from 1 mode to another and then off (reset to 0)
i am new to all this so i got bits of code from here and there...
The question is asking what the resistance of the first resistor is (which has been labelled as 0 ohms on the diagram). I am told 20v drops across the first resistor and i am given the value of the other resistor. Now both of the methods I am sure I've done correctly but I'm getting different...
Hi guys !
First i'm new member here with you , and i hope you guys help me with my power supply kit problem:
Like most people , i have problem with this kit wich is i get -0.45v when the V and A pot are fully anti-clockwise and i get only 5.1V when the V and A are fully clockwise.
I checked...
Hello,
I'm currently working on a project that requires the use of an MCP475 DAC. Currently, it is being powered from the 3.3V source from on a Raspberry Pi and hence works in the range of 0V to 3.3V.
I need it to work in the range of -3.3V to +3.3V. By reading the spec sheets I found that I...

What's the difference between Vt+ and Vhigh and Vt- and Vlow ??
please help me!
I need to design a circuit to calculate the product of two 4-bit binary numbers, and then display the decimal result in three HEX displays.I already have the multiplication part, but the hex baffles me since :
1-The inputs are two 4-bit binary numbers.
2-The system can display each input...
I've been designing a simple random number generator that is supposed to generate a number from 1-100 and display it using three 7-segment displays(D0, D1, D2). This design also uses a 555 timer(astable 1400Hz) and two BCD decade counters. For D0 and D1, I am using CD74HC4511E decoders, which...
