Can anyone help explain how to send message to zwave trhough rs232? I am using zensys controller libraries and want to send a command to the zwave zw0301 to request for the firmware version ?
Theres a lot of C# api but I don't really understand how or what functions/class to use. Any examples...
Im debating on which one to buy, the Hantek MSO5074FG or the Rigol DS1074Z or Rigol DS1074Z-S. Same screen size for all models.
Im on a budget but im willing to spend ONLY if its worth it.
MSO5074FG spec: 4 channels, 70MHz bandwidth, 8 channel logic analyzer, 2 channel 25MHz function...
Just apply the equation you have E=1/2CV^2. I think you didn't get the correct answer because you either have the paranthese in the wrong place or maybe you are not in radians.
E=(1/2)*(1000uF)*((1.5*cos(100000 *50us))^2)
Remember only the voltage is squared. So V=1.5cos(100000*t) where t=50us...
Anyone know a cheap place to make pcb? I am thinking of making a 4in x 4in board. All the places ive looked at, with a 4in x 4in it would cost roughly $90 to $100! I am looking for places that could possibly cost me $50 or less. I am hobbyist but I get discouraged making projects because it cost...
Help me understand, for a 2 layer, if bottom is ground and top is power...wouldn't all the component on top be all connected to power??....Guess im confused
I am making a 2 layer PCB for a motor driver, whats the typical layout for a 2 layer pcb?
Is one layer lets say the bottom ground? And the top layer for power and connection of components? Or how should I do this, the expected current draw will be around 15+ amps continuous.
by putting resistor in parallel with the caps to help keep the charge the same would just be a waste of energy because the resistor would just be eating it up.
These PIR don't really have a "communication protocol" unless they changed it. Its just an open collector output, when it detects movement it turns on the transistor, that's it, nothing you need to do. Just connect a pull up resistor to the output of the sensor and connect the output to a DIO...
In theory yes you will 10 volts out after fully charge but you have to becareful...if the two caps are of different (capacitance and leakage resistance), most likely it is because no 2 components are identical in real life, you can blow up the caps.
I have one of these before, I believe the output is an open collector, meaning you will need a pullup resistor. You cant just connect directly to it.
Tie the ouput to a resistor, and connect the resistor to VCC. The output also goes to PIC dio pins.
If the sensor uses the same voltage as the PIC, then just connect directly to a DIO or if it outputs analog, then connect to the analog channel. Read the datasheet for the sensor, they will tell you what it needs, sometimes it requires some resistor connected to it.
Then you just set the PIC...
Are you using an IC to driver the H-Bridge or are you making your own circuit? The motor you are using doesn't even draw a lot of current. Like other people who posted here, you need to provide more info...what kind of mosfets are u using, wheres your circuit? Can your mosfet handle the load? It...
I am using orcad and am having a hard time finding useful tutorial on how to make footprints in orcad. I know theres a wizard in orcad to make parts, but sometimes theres odd parts that doesn't fit those templates and you have to create your own but I cannot find any resource about it. I think...
Anyone use the LT1158CN mosfet bridge driver?? I tried wiring up the same as the example they have and use a small brushed dc motor as load and BOTH of my mosfet gets hot...but the motor runs. The bottom shouldn't get hot because I am only driving the top. The datasheet also said the input pin...
